Mary Berry Chocolate Mirror Cake Recipe

Ingredients Needed

Mary Berry’s Chocolate Mirror Cake is an indulgent dessert that combines a rich, moist chocolate cake with a stunning mirror glaze finish. To create this show-stopping cake, you’ll need a few carefully selected ingredients, each contributing to the cake’s moist texture, luscious flavor, and glossy appearance.

For The Cake

1. Self-Raising Flour (225g)

   The self-raising flour ensures the cake has a light and airy crumb, giving it the perfect texture. The rising agents in the flour will help it rise effortlessly, providing a soft, spongy base for the cake.

2. Cocoa Powder (50g)

   Unsweetened cocoa powder adds a deep, rich chocolate flavor to the cake, creating a strong, satisfying taste that balances perfectly with the sweetness of the cake. Opt for good quality cocoa powder for the best results.

3. Baking Powder (1 tsp)

   Although the self-raising flour already contains a rising agent, the extra bit of baking powder ensures that the cake rises uniformly, especially with the added cocoa powder that can sometimes weigh the batter down.

4. Unsalted Butter (225g, softened)

   Butter is the key to achieving a tender, flavorful cake. The fat content of butter contributes to the rich, moist texture that Mary Berry’s recipes are so well-known for. Make sure it’s softened to room temperature for easier incorporation into the batter.

5. Caster Sugar (225g)

   Caster sugar has fine granules that dissolve more quickly into the batter than regular sugar, ensuring an evenly sweet cake without any grainy texture. It provides the cake with the necessary sweetness.

6. Eggs (4 large)

   Eggs are essential for binding the ingredients together and adding structure to the cake. They also contribute to the cake’s moisture and help it rise during baking.

7. Whole Milk (200ml)

   Whole milk adds moisture to the cake, preventing it from becoming dry. The richness of the milk complements the cocoa flavor, ensuring a soft, moist crumb.

8. Vanilla Extract (1 tsp)

   While this cake is primarily about chocolate, the addition of vanilla extract enhances the overall flavor profile, rounding out the sweetness and adding a subtle depth to the taste.

For The Chocolate Mirror Glaze

1. Dark Chocolate (200g, finely chopped)

   Dark chocolate with a high cocoa content (around 70%) works best for the mirror glaze, giving it an intense, deep chocolate flavor and a glossy finish. Chop it finely so that it melts evenly and smoothly.

2. Double Cream (150ml)

   The heavy cream helps create a smooth, silky texture for the glaze, making it easy to pour over the cake. It also gives the glaze a beautiful shine, turning the cake into a true showpiece.

3. Golden Syrup (1 tbsp)

   Golden syrup adds a subtle sweetness and helps to achieve the perfect glossy finish for the glaze. It’s a key ingredient for getting that mirror-like shine.

4. Gelatin Sheets (2)

   Gelatin helps the glaze set perfectly on the cake, ensuring that it remains firm and doesn’t slide off once applied. It contributes to the signature mirror-like texture, giving the glaze its incredible smoothness.

Equipment Needed

Creating Mary Berry’s Chocolate Mirror Cake requires a few essential pieces of equipment to ensure everything comes together seamlessly, from the baking process to the final glazing.

1. Cake Tin (23cm / 9-inch round, deep)

   A deep, round cake tin is crucial to give the cake its desired height and texture. Ensure the tin is lined properly with parchment paper to help with easy removal after baking.

2. Mixing Bowls

   You’ll need separate bowls for the dry ingredients, wet ingredients, and the batter. Using large, spacious bowls ensures that everything is thoroughly mixed without splattering.

3. Electric Mixer or Whisk

   An electric mixer helps to speed up the creaming process, allowing the butter and sugar to reach the light, fluffy texture needed for a great cake. If you prefer a more hands-on approach, a whisk can work, but an electric mixer makes it much easier.

4. Spatula

   A flexible spatula is invaluable when folding the ingredients together. It helps prevent over-mixing and ensures that all the ingredients are incorporated without deflating the batter.

5. Saucepan and Heatproof Bowl (for Glaze)

   You’ll need a saucepan to heat the cream and golden syrup, and a heatproof bowl to melt the chocolate. A double boiler method (heating the bowl over the simmering water) is perfect for melting chocolate without burning it.

6. Cooling Rack

   A cooling rack is necessary to allow the cake to cool evenly after baking. This prevents any sogginess from forming at the bottom, which is especially important if you’re glazing the cake right after.

7. Pastry Brush

   If you want to smooth out the glaze and ensure it’s evenly spread across the cake, a pastry brush will come in handy for applying the final mirror glaze layer.

How To Make Mary Berry’s Chocolate Mirror Cake

Step 1: Prepare The Cake

• Preheat your oven to 180°C (160°C fan) or 350°F (320°F fan).
• Grease your cake tin and line the bottom with parchment paper to prevent sticking.
• In a large bowl, sift together the self-raising flour, cocoa powder, and baking powder. This will help to avoid lumps and ensure even distribution of the dry ingredients.
• Using an electric mixer, beat the softened butter and caster sugar together until pale and fluffy. This may take about 3-5 minutes.
• Add the eggs one at a time, beating well after each addition. If the mixture starts to curdle, add a spoonful of the sifted flour mixture to stabilize it.
• Add the vanilla extract, followed by the milk, mixing gently until smooth.
• Gradually fold in the dry ingredients using a spatula until fully combined. Be careful not to overmix to maintain a light texture.
• Pour the batter into the prepared tin and smooth the top.
• Bake in the preheated oven for 25-30 minutes, or until a skewer inserted into the center comes out clean. Let the cake cool in the tin for 10 minutes, then transfer it to a wire rack to cool completely.

Step 2: Prepare The Chocolate Mirror Glaze

• Begin by soaking the gelatin sheets in cold water for about 5 minutes.
• In a saucepan, heat the double cream and golden syrup over medium heat, stirring occasionally. Once it’s hot but not boiling, remove it from the heat.
• Add the chopped dark chocolate to the cream mixture, stirring until fully melted and smooth.
• Gently squeeze out the water from the gelatin sheets and add them to the warm chocolate mixture, stirring until dissolved completely.
• Allow the glaze to cool slightly before pouring it over the cooled cake. It should be around 35°C (95°F) for the perfect texture.

Step 3: Glaze The Cake

• Place the cooled cake on a wire rack or a cake stand, with a tray underneath to catch any excess glaze.
• Pour the mirror glaze slowly over the top of the cake, letting it spill over the sides in an even layer. Use a spatula to help smooth the glaze if needed.
• Let the glaze set for about 30 minutes before serving, allowing it to form a beautiful mirror-like shine.

Expert Tips

1. Use Room Temperature Ingredients

   Ensure your butter, eggs, and milk are at room temperature before beginning the recipe. This allows them to mix more easily and results in a smoother batter.

2. Double the Glaze for Extra Shine

   If you want an even more dramatic mirror finish, you can double the glaze ingredients and pour on a second layer once the first one has set.

3. Chill the Cake Before Glazing

   If your cake is slightly warm when you add the glaze, the glaze may melt into the cake and lose its shine. Make sure the cake is completely cool before glazing for the best result.

4. Use Quality Chocolate

   Since the chocolate is the star of the glaze, using high-quality dark chocolate will elevate the flavor and texture of the entire cake.

Mary Berry’s Chocolate Mirror Cake is a stunning dessert that combines indulgence with elegance. The rich, moist chocolate cake paired with the smooth, glossy mirror glaze creates a showstopper worthy of any occasion.

The simple ingredients and straightforward steps make it accessible for bakers of all levels, while the expert tips ensure your cake turns out perfectly every time. Whether for a birthday, a special celebration, or just to impress your loved ones, this cake will undoubtedly leave a lasting impression with both its taste and its visual appeal.

Easy Recipe Variations For Mary Berry’s Chocolate Mirror Cake

Mary Berry’s Chocolate Mirror Cake is a showstopper in its own right-smooth, glossy, and undeniably rich. But the beauty of a recipe like this lies in its adaptability. While Mary’s version is a classic, there are countless ways to tweak and personalize the recipe, giving you ample room to experiment while staying true to its delicious core.

1. Flavouring the Ganache

   The mirror glaze that defines the cake is an opportunity to add subtle flavors beyond the traditional chocolate. For a citrus twist, try infusing the glaze with orange or lemon zest.

   A splash of liqueur such as Grand Marnier, rum, or Baileys can also elevate the ganache’s richness and depth. You could even experiment with herbs like mint or lavender for a refreshing contrast to the sweetness of the cake.

2. Adding Fruit Layers

   One easy variation is to add a layer of fresh fruit or fruit preserves in between the layers of the cake. Raspberries, strawberries, or cherries pair beautifully with the dark richness of chocolate, adding both color and a tangy contrast. A fruit compote or even a dollop of raspberry coulis beneath the ganache creates an unexpected surprise when cutting into the cake.

3. Different Types of Chocolate

   If you’re a chocolate connoisseur, consider mixing up the types of chocolate in the mirror glaze and cake layers. Dark chocolate brings out a rich, bittersweet flavor, but milk or white chocolate can create a creamier, sweeter experience. For a truly indulgent twist, blend different types of chocolate for a multilayered flavor profile that will appeal to all palates.

4. Adding Nuts for Texture

   Mary’s original recipe is quite smooth and elegant, but adding a crunch factor can add an interesting dimension. You can sprinkle chopped hazelnuts, almonds, or pistachios in the ganache or between layers for a delightful contrast in texture. These nuts also provide an earthy, nutty depth to the flavor.

5. Coffee Infusion

   For those who love coffee and chocolate pairings, consider infusing the cake batter with a shot of espresso or strong brewed coffee. The coffee not only enhances the chocolate’s depth but also brings a bit of warmth and richness to the overall flavor. You can even add a dash of coffee liqueur to the glaze for added intensity.

6. Dairy-Free or Vegan Option

   For those with dietary restrictions, adapting Mary Berry’s Chocolate Mirror Cake to be dairy-free or vegan is surprisingly simple. You can substitute regular butter with plant-based margarine or coconut oil, and swap out heavy cream for coconut cream or any non-dairy milk like almond or oat milk. Vegan-friendly chocolate options are abundant now, so there’s no reason you can’t enjoy this decadent cake without compromising on flavor.

7. Mini Mirror Cakes or Cupcakes

   For an elegant, individual twist, consider making mini versions of the cake. The mirror glaze will look just as stunning on small cakes or cupcakes as it does on a large one. These bite-sized treats are perfect for parties, making them easy to serve and enjoy.

By adding simple twists like these to Mary Berry’s Chocolate Mirror Cake, you can adapt it to different tastes, occasions, or dietary preferences, all while maintaining its iconic elegance.

Best Practices To Store Leftovers

One of the greatest challenges with making a cake as delicious as Mary Berry’s Chocolate Mirror Cake is how to store the leftovers (assuming there are any!). Fortunately, when stored properly, this decadent dessert can stay fresh for days. Below are some essential tips for keeping your mirror cake in the best condition:

1. Refrigeration Is Key

   The chocolate mirror glaze on the cake is quite delicate and can be prone to melting or losing its shine if not stored properly. Store the leftover cake in the refrigerator to keep both the cake and the glaze intact. Place it in an airtight container or wrap it in plastic wrap to prevent the cake from drying out or absorbing any unwanted odors from the fridge.

2. Avoid Slicing Until Ready to Serve

   If you know you won’t be finishing the cake in one sitting, try to avoid slicing it too early. The more you cut into the cake, the more surface area becomes exposed to air, which can dry it out. It’s best to slice off individual portions only as needed.

3. Allow Cake to Come to Room Temperature Before Serving

   While the cake should be stored in the fridge, serving it straight from the fridge might not showcase its full flavor. The coldness can mute the chocolate’s taste.

   Take the cake out of the fridge about 30-60 minutes before serving, allowing it to return to room temperature. This will help preserve the rich, velvety texture of the ganache and the moistness of the cake.

4. Freezing for Long-Term Storage

   If you’ve made a large batch or need to keep leftovers for a longer period, freezing is an option. To freeze the cake, first slice it into individual portions (or leave it whole, depending on preference).

   Wrap each piece tightly in plastic wrap, followed by aluminum foil, and store it in a freezer-safe container. The cake can last up to a month in the freezer. When ready to eat, allow it to thaw in the fridge overnight and then bring it to room temperature before serving.

5. Reheating Tips

   If you prefer a warm slice of chocolate cake, gently reheat individual portions in the microwave for 15-20 seconds. Be cautious not to overheat, as this could cause the ganache to melt. Alternatively, you can heat it in an oven at a low temperature (around 160°C or 320°F) for 5-10 minutes.

6. Storage of Leftover Ganache

   If you happen to have leftover ganache after glazing, you can store it in an airtight container in the refrigerator for up to a week. You can even repurpose it as a dip, spread, or topping for other desserts like ice cream or fruit. If it becomes too firm after chilling, gently heat it up to return it to a pourable consistency.

By following these best practices, you can keep your chocolate mirror cake fresh for several days and still enjoy its rich, indulgent flavors without losing any of its signature appeal.

What Goes Well With Chocolate Mirror Cake

Mary Berry’s Chocolate Mirror Cake, with its smooth ganache and moist chocolate layers, is already a complete experience on its own. But pairing it with the right accompaniments can enhance the flavors and elevate your dessert table to new heights. Here are a few delicious options to pair with this decadent treat:

1. Fresh Berries

   The tartness of fresh berries provides a perfect contrast to the rich sweetness of the chocolate. Raspberries, strawberries, or blueberries are the most popular choices, but blackberries or even a mix of tropical fruits like pineapple and mango can work well. The vibrant color of the berries also adds a lovely visual contrast to the dark, glossy cake.

2. Whipped Cream or Crème Fraîche

   Sometimes, the simplest additions are the best. A dollop of freshly whipped cream or a spoonful of crème fraîche can balance the cake’s richness with their lightness and slight tang. You can flavor the whipped cream with a touch of vanilla, or for something more indulgent, whip it with a bit of powdered sugar to create a sweeter complement.

3. Ice Cream or Sorbet

   Chocolate and ice cream are a classic pairing, and there’s no better time to indulge than when you’re serving a cake as luxurious as this one. Rich vanilla bean ice cream, salted caramel, or even a coffee-flavored gelato would be delicious alongside a slice. For a lighter, fruitier option, a scoop of sorbet-perhaps raspberry or lemon-adds a refreshing, zesty contrast.

4. Nuts and Caramel

   Candied or roasted nuts like pecans, hazelnuts, or almonds bring a satisfying crunch and depth of flavor when paired with chocolate cake. You could even drizzle some homemade caramel sauce over the cake or serve it alongside a bowl for dipping, enhancing the overall richness with a sweet, buttery element.

5. Coffee or Hot Chocolate

   For an afternoon tea or cozy dessert experience, pair the cake with a rich cup of coffee or espresso. The slightly bitter notes of the coffee balance out the sweetness of the cake, creating a harmonious contrast. If you want to indulge further, serve the cake with a mug of hot chocolate, rich in flavor and perfect for a chocolate lover’s dream pairing.

6. A Glass of Dessert Wine

   For a more sophisticated pairing, consider serving the chocolate mirror cake with a dessert wine such as a rich port, sherry, or a late harvest Riesling. The natural sweetness of the wine complements the cake’s richness while the wine’s acidity helps cut through the density of the ganache.

7. Chocolate Truffles or Mousse

   If you can’t get enough chocolate, you can serve the cake alongside small, rich chocolate truffles or a velvety chocolate mousse. These extras add a touch of variety while still remaining in the realm of deep, luxurious chocolate flavor.

These accompaniments not only enhance the flavor but also transform the chocolate mirror cake into a more complex, multi-sensory experience, perfect for impressing guests or simply treating yourself.
