Mary Berry Chocolate Traybake Recipe

Ingredients Needed

When preparing Mary Berry’s Chocolate Traybake, the key to achieving a moist, chocolatey, and beautifully textured cake lies in the ingredients. Here’s a list of all the essentials to ensure your traybake turns out perfectly:

1. Butter (unsalted) – 225g (8 oz)

   • Butter is an essential fat in the recipe, providing richness and moisture to the cake. Using unsalted butter is important so you can control the amount of salt in the recipe, and it melts beautifully when mixed with other ingredients.

2. Caster Sugar – 225g (8 oz)

   • Caster sugar, with its fine texture, dissolves easily into the batter, ensuring that the cake has a light and airy texture. This is a great choice for baked goods because it helps achieve the perfect balance between sweetness and tenderness.

3. Self-raising Flour – 225g (8 oz)

   • Self-raising flour has baking powder already mixed into it, making it an excellent choice for giving the traybake its rise. It ensures the cake comes out light and fluffy without needing to separately add leavening agents.

4. Cocoa Powder (unsweetened) – 3 tablespoons

   • This is where the deep, chocolatey flavor comes from. Unsweetened cocoa powder adds a rich, slightly bitter note that balances the sweetness of the sugar. Opting for a good-quality cocoa powder will make a huge difference in the final taste.

5. Eggs – 3 large

   • Eggs contribute to the structure of the cake, helping it rise and bind the ingredients together. They also provide moisture, ensuring the cake isn’t dry.

6. Milk – 2 tablespoons

   • A splash of milk ensures the batter achieves a smooth, pourable consistency. The milk also adds a creamy richness that enhances the flavor.

7. Baking Powder – 1 teaspoon

   • While self-raising flour has some leavening built-in, an extra teaspoon of baking powder gives the cake that extra rise, ensuring it’s perfectly light and fluffy.

8. Vanilla Extract – 1 teaspoon

   • Vanilla extract is the secret ingredient that elevates the flavor profile of the traybake. It enhances the chocolate notes and provides a lovely, fragrant undertone.

9. For The Icing

   • Butter (unsalted) – 50g (1¾ oz)
   • Cocoa Powder (unsweetened) – 2 tablespoons
   • Icing Sugar – 200g (7 oz)
   • Milk – 2 tablespoons
   • The icing is what brings this traybake to the next level. It’s smooth, glossy, and intensely chocolatey. Butter and cocoa powder provide the base, while icing sugar creates that perfect texture to spread over the top.

Equipment Needed

Making a Mary Berry Chocolate Traybake doesn’t require specialized equipment, but you’ll need a few key items to ensure everything goes smoothly:

1. Large Mixing Bowl

   • You’ll need a spacious bowl to combine your ingredients without making a mess. A large mixing bowl is perfect for stirring the dry ingredients with the wet ingredients to create the batter.

2. Electric Hand Mixer Or Stand Mixer

   • While you can mix by hand, an electric hand mixer or a stand mixer saves time and energy, ensuring the butter and sugar blend together thoroughly, and the eggs are beaten into a smooth mixture.

3. Measuring Scales

   • Precision in baking is crucial, so a set of reliable measuring scales will ensure you have the correct proportions of ingredients.

4. Baking Tray (approximately 30×20 Cm Or 12×8 Inches)

   • A rectangular or square baking tray with these dimensions is ideal for this traybake recipe. It provides ample space for the cake to bake evenly and gives you that perfectly squared shape once it’s cooled.

5. Parchment Paper Or Baking Liner

   • Line your tray with parchment paper or a baking liner to prevent sticking and ensure the traybake comes out in one smooth piece once baked.

6. Sifter Or Fine-Mesh Strainer

   • For a smooth and clump-free cocoa powder, it’s a good idea to sift it before adding it to the dry ingredients. This ensures your cake’s texture is velvety and uniform.

7. Cooling Rack

   • Once the traybake has finished baking, transfer it to a cooling rack to prevent the bottom from becoming soggy as it cools. This helps preserve the cake’s structure.

8. Spatula

   • A spatula is your best friend when it comes to spreading the smooth icing over the top of your traybake. It ensures an even layer that’s both aesthetic and delicious.

9. Sharp Knife

   • To cut your finished traybake into neat squares, a sharp knife is essential. This will help achieve clean edges without disturbing the texture of the cake.

How To Make Mary Berry’s Chocolate Traybake

Making Mary Berry’s Chocolate Traybake is surprisingly simple, yet it results in an incredibly satisfying, indulgent dessert. Here’s a step-by-step guide to ensure your cake is as delicious as the original:

1. Preheat your oven to 180°C (160°C fan)/350°F/Gas Mark 4. Line your baking tray with parchment paper, ensuring it covers the bottom and sides for easy removal later.

2. Cream the butter and sugar. In a large mixing bowl, use an electric mixer to beat the softened butter and caster sugar together until the mixture is light, fluffy, and pale. This process helps incorporate air into the batter, which will make your cake light and tender.

3. Add the eggs one at a time. Crack the eggs into a separate bowl and add them to the butter-sugar mixture, one at a time, beating well after each addition. This ensures the eggs are properly incorporated into the batter and prevents curdling.

4. Combine the dry ingredients. In another bowl, sift the self-raising flour and cocoa powder together. Add the baking powder and stir to combine.

5. Add the dry ingredients and milk. Gradually fold the dry mixture into the wet ingredients, alternating with the milk. Use a spatula or spoon to gently combine everything until you have a smooth batter.

6. Pour the batter into the prepared tray. Once the batter is smooth, pour it into your lined baking tray and spread it out evenly with the back of a spoon or spatula.

7. Bake the traybake. Place the tray in the oven and bake for 25-30 minutes, or until a skewer inserted into the center comes out clean. The cake should be springy to the touch.

8. Cool the cake. Once baked, remove the tray from the oven and leave the cake to cool in the tray for about 10 minutes. Then, transfer it to a cooling rack to cool completely before icing.

9. Prepare the icing. While the cake is cooling, make the icing. Melt the butter in a small saucepan over low heat, then stir in the cocoa powder. Gradually mix in the icing sugar and milk until the icing is smooth and glossy.

10. Ice the cake. Once the cake has cooled completely, spread the chocolate icing evenly over the surface using a spatula.

11. Cut and serve. Let the icing set for a few minutes before cutting the traybake into squares. Serve and enjoy the rich, chocolatey goodness!

Expert Tips

• Room Temperature Ingredients: Ensure the butter and eggs are at room temperature before starting. This helps them incorporate better and results in a smoother batter.

• Sift Your Dry Ingredients: Sifting the flour and cocoa powder eliminates any lumps, resulting in a smoother batter and a finer texture in the finished cake.

• Don’t Overmix: Once you add the dry ingredients, mix gently. Overmixing can lead to a dense and tough cake.

• Check for Doneness Early: Oven temperatures can vary, so start checking your cake after 25 minutes by inserting a skewer. If it comes out clean, the cake is done. If not, leave it for a few more minutes.

• Customize Your Icing: If you prefer a thicker or thinner icing, adjust the milk to your liking. You could also add a pinch of sea salt to balance the sweetness or a teaspoon of instant coffee for a deeper chocolate flavor.

Easy Recipe Variations For Mary Berry’s Chocolate Traybake

Mary Berry’s Chocolate Traybake is a classic, rich treat that has captured the hearts of many bakers. Its simplicity, ease, and ability to be modified in countless ways make it a versatile recipe in any home kitchen. While the original recipe is delightful on its own, there are many variations you can try to customize the flavor and texture to suit your tastes or add a twist of creativity.

1. Adding Nuts: One of the easiest ways to enhance the chocolate traybake is by incorporating nuts. Walnuts, hazelnuts, or almonds can be folded into the batter before baking, or sprinkled on top to add a delightful crunch. Toasting the nuts beforehand will release their oils and deepen their flavor, making them even more aromatic when combined with the chocolate.

2. Swapping the Chocolate: While the recipe typically calls for dark or milk chocolate, experimenting with different types of chocolate can create exciting variations. Try using white chocolate for a sweeter, milder result, or opt for a combination of dark chocolate and salted caramel for a sophisticated, complex flavor. You can even add a dash of espresso powder to intensify the chocolate taste, creating a deep, rich profile that pairs beautifully with the sweetness of the cake.

3. Fruits and Berries: If you’re looking to bring some fruity freshness to the traybake, why not fold in some berries or dried fruits?

   Fresh raspberries or blackberries can add a tart contrast to the rich chocolate, or dried cherries and apricots can provide a sweet and chewy texture. A sprinkle of freeze-dried strawberries on top before baking adds color, flavor, and a light tang that complements the chocolate wonderfully.

4. Adding a Layer of Ganache: For an extra indulgent treat, you can top the traybake with a layer of glossy chocolate ganache. Simply heat heavy cream and pour it over chopped chocolate, stirring until it’s smooth and silky. Spread this over the cooled traybake for a glossy, decadent finish. You can also flavor the ganache with a hint of vanilla, orange zest, or even a splash of liqueur, such as Grand Marnier or Baileys, to elevate the experience.

5. Making It Vegan or Dairy-Free: If you’re catering to dietary preferences or restrictions, it’s easy to adjust the chocolate traybake to be vegan or dairy-free. Replace butter with coconut oil or a dairy-free margarine and use a plant-based milk like almond or oat milk instead of cow’s milk. For the chocolate, look for dairy-free chocolate chips or bars. With these swaps, you can still enjoy the richness and fudginess of the traybake without the dairy!

6. Infused Flavors: For those who enjoy a bit of flair in their bakes, try infusing the cake with different flavors like orange zest, mint, or even a hint of chili for a spicy kick. You can add finely chopped mint leaves to the batter or zest a fresh orange and fold it in to add a refreshing burst of citrus that balances the richness of the chocolate. A touch of ground cinnamon or chili powder can create a warm, aromatic twist, perfect for those looking to experiment with flavors beyond the usual chocolate.

Best Practices To Store Leftovers

Once you’ve baked Mary Berry’s Chocolate Traybake and indulged in its decadence, you may have leftovers to store. Proper storage is key to keeping your traybake fresh and delicious for as long as possible. Here’s how to keep your leftovers in optimal condition:

1. Let It Cool First: Before storing any leftover cake, make sure it’s completely cooled to room temperature. This prevents condensation from forming inside the storage container, which could make the cake soggy and affect its texture.

2. Use Airtight Containers: To maintain the freshness and prevent the cake from drying out, store the chocolate traybake in an airtight container. If you don’t have a large enough container, wrap the traybake tightly in plastic wrap, then place it in a resealable plastic bag or another airtight container. This helps keep moisture in and preserves the cake’s softness and flavor.

3. Refrigeration: If you plan to keep the traybake for more than a couple of days, refrigeration is a good idea. The cake should last for about 5-7 days in the fridge. However, make sure to let it come to room temperature before serving for the best taste and texture.

4. Freezing for Long-Term Storage: If you want to store the traybake for an extended period, freezing is a great option. Cut the cake into individual portions to make defrosting easier. Wrap each slice tightly in plastic wrap and then place them in a freezer-safe bag or container. When you’re ready to enjoy, simply remove a portion and let it thaw at room temperature, or gently heat it in the microwave for a few seconds.

5. Avoid Over-Storing: Like most baked goods, chocolate traybakes are best enjoyed within a reasonable time frame. Even with proper storage, the cake can lose some of its charm if stored for too long. A good rule of thumb is to enjoy your traybake within a week, even when refrigerated.

What Goes Well With Chocolate Traybake

While Mary Berry’s Chocolate Traybake is delicious on its own, pairing it with complementary flavors and textures can elevate the experience to new heights. Here are some suggestions for what goes well with this delightful treat:

1. Fresh Fruit: The richness of the chocolate traybake pairs wonderfully with the freshness of fruits like raspberries, strawberries, or orange slices. The tartness of the berries balances the sweetness of the cake, while the citrus adds a refreshing note that cuts through the chocolate’s richness.

2. Whipped Cream or Ice Cream: For those who enjoy an indulgent dessert experience, serving the chocolate traybake with a dollop of freshly whipped cream or a scoop of vanilla ice cream is a classic choice. The cold creaminess of the ice cream or the lightness of whipped cream contrasts beautifully with the dense, fudgy texture of the traybake.

3. Coffee or Tea: Chocolate and coffee are a match made in heaven. A strong espresso, cappuccino, or even a cup of rich hot chocolate can complement the deep chocolate flavor in the traybake. For a lighter pairing, try a cup of Earl Grey or a rich, smooth black tea, whose notes of citrus and bergamot add another layer of flavor.

4. Nuts and Seeds: If you’ve already added nuts into your traybake, you can further enhance the experience by serving it with a few extra roasted almonds, pecans, or even a sprinkle of pumpkin or sunflower seeds. These add texture and a savory element that pairs well with the sweetness of the chocolate.

5. Caramel or Toffee Sauce: For an extra layer of decadence, drizzle some warm caramel or toffee sauce over the top of your traybake. The buttery, rich flavor of the sauce complements the chocolate, creating a heavenly combination. For a more sophisticated option, you could serve the traybake with a salted caramel sauce to provide a sweet-salty contrast.
