Mary Berry’s Walnut and Coffee Sandwich Cake is a delightful treat that combines the earthy richness of walnuts with the robust flavor of coffee. The ingredients for this cake are simple yet indulgent, giving you a beautiful, textured dessert that’s perfect for any occasion. Here’s what you’ll need:

1. For The Cake

   • Butter (softened): About 200g of unsalted butter, ensuring it is at room temperature for easy creaming with sugar.
   • Caster Sugar: 200g of caster sugar to give the cake a fine, smooth texture.
   • Eggs: Four large eggs, ideally at room temperature, which helps the batter to emulsify better.
   • Self-Raising Flour: 200g of self-raising flour, which will provide the cake with the necessary lift, creating a light texture.
   • Ground Coffee: 2 tablespoons of instant coffee or espresso powder, dissolved in a bit of hot water to infuse the batter with a strong, rich coffee flavor.
   • Ground Walnuts: 100g of ground walnuts, which give the cake a nutty, earthy flavor while also adding texture.
   • Baking Powder: A teaspoon of baking powder to further assist in the rising process, ensuring the cake remains light and fluffy.
   • Milk: 2 tablespoons of milk to loosen the batter, ensuring it’s the right consistency to pour into the tin.

2. For The Coffee Buttercream Filling

   • Butter (softened): 100g of unsalted butter, at room temperature, which will be the base for the smooth buttercream.
   • Icing Sugar: 200g of icing sugar for a light, sweet texture that will blend seamlessly with the butter.
   • Instant Coffee: 1 tablespoon of instant coffee dissolved in hot water for that signature coffee flavor.
   • Vanilla Extract: 1 teaspoon of vanilla extract for a hint of warmth to balance the strong coffee flavor.

3. For The Decoration

   • Walnut Halves: A handful of walnut halves, roughly 8-10, to decorate the top of the cake and provide an extra crunch and nutty flavor.

Equipment Needed

To make Mary Berry’s Walnut and Coffee Sandwich Cake, you’ll need a few essential kitchen tools and equipment to ensure a smooth and successful baking experience. Here’s what you’ll need:

1. Mixing Bowls: A couple of medium-sized mixing bowls for combining dry ingredients, wet ingredients, and for making the buttercream.

2. Electric Mixer (Handheld or Stand Mixer): A handheld electric mixer or stand mixer makes the process of creaming the butter and sugar easier, as well as ensuring the eggs and flour are incorporated thoroughly without over-mixing.

3. Sieve: A fine sieve for sifting the self-raising flour, which helps aerate the flour and prevents lumps from forming.

4. Cake Tins: Two 20cm (8-inch) round cake tins. The cake batter will be divided evenly between these two tins to create the sandwich-style layers.

5. Spatula: A rubber or silicone spatula for folding ingredients gently, ensuring a smooth batter and a light cake texture.

6. Cooling Rack: A cooling rack to let the cakes cool properly after baking, which is essential for preventing them from becoming soggy.

7. Piping Bag (Optional): While a spatula can be used to spread the buttercream, a piping bag will give you more control and precision when filling the cake.

8. Baking Paper: For lining the cake tins to prevent sticking, ensuring the cakes come out easily after baking.

9. Small Bowl (for coffee): A small heatproof bowl to dissolve the instant coffee in hot water for both the cake and buttercream.

How To Make Mary Berry’s Walnut And Coffee Sandwich Cake

1. Prepare The Oven And Tins

   Preheat the oven to 180°C (350°F) or 160°C (320°F) for fan ovens. Line the two 20cm cake tins with baking paper and lightly grease them. This will prevent the cake from sticking and ensure a smooth removal after baking.

2. Make The Coffee And Nut Mixture

   In a small bowl, dissolve the 2 tablespoons of instant coffee in 2 tablespoons of hot water. Allow this to cool.

   Then, mix the ground walnuts with the flour and baking powder in a separate bowl. Sifting the flour before mixing with the other ingredients will keep the texture light.

3. Cream The Butter And Sugar

   In a large bowl, use an electric mixer to cream together the softened butter and caster sugar until the mixture is pale and fluffy. This step helps to create air pockets in the batter, making the cake light and airy.

4. Add The Eggs

   Crack the eggs into the creamed butter and sugar, one at a time, beating well between each addition. This prevents the mixture from curdling. If the mixture starts to split, you can add a tablespoon of flour to help it come together.

5. Fold In The Dry Ingredients

   Gradually fold in the sifted flour, walnut, and baking powder mixture using a spatula. Add the cooled coffee and mix until just combined. Be careful not to over-mix, as this can make the cake dense.

6. Bake The Cakes

   Divide the batter evenly between the two prepared cake tins, smoothing the tops with a spatula. Bake in the preheated oven for about 25-30 minutes or until a skewer inserted into the center comes out clean. The cakes should be golden brown and spring back when lightly pressed.

7. Cool The Cakes

   Once baked, remove the cakes from the oven and let them cool in the tins for 10 minutes before transferring them to a wire rack to cool completely.

8. Prepare The Buttercream

   While the cakes are cooling, make the coffee buttercream. Beat the softened butter with the icing sugar until smooth and creamy.

   Then, add the dissolved coffee and vanilla extract. Mix well to combine, ensuring the buttercream is light and fluffy.

9. Assemble The Cake

   Once the cakes are completely cooled, place one layer on a serving plate. Spread a generous layer of coffee buttercream over the top of the first cake layer. Place the second cake on top and press down gently to sandwich them together.

10. Decorate

    Decorate the top of the cake with walnut halves, placing them in a decorative pattern, and perhaps even dusting the top with a little extra icing sugar if desired.

Expert Tips For Making Mary Berry’s Walnut And Coffee Sandwich Cake

1. Room Temperature Ingredients: For the best results, make sure your butter, eggs, and milk are at room temperature before starting. This ensures they mix together smoothly, which is crucial for the texture of the cake.

2. Don’t Overmix the Batter: When folding in the flour and walnuts, be gentle. Over-mixing can result in a dense cake, so aim for just enough mixing to combine the ingredients without beating too vigorously.

3. Use Fresh Coffee: Freshly brewed coffee or high-quality instant coffee can make a noticeable difference in the flavor of the cake. Ensure that the coffee is strong enough to give the cake a deep, rich coffee taste but not overpowering.

4. Cool Cakes Completely: It’s essential that the cakes cool fully before you add the buttercream filling. If they’re too warm, the buttercream can melt and slide off, resulting in a messy finish.

5. Decorate with Precision: When decorating with walnuts, consider using whole walnut halves to give the cake a more elegant, polished look. This creates an inviting contrast between the smooth buttercream and the nutty texture.

Mary Berry’s Walnut and Coffee Sandwich Cake is a wonderfully indulgent dessert that combines the flavors of rich coffee and crunchy walnuts in a soft, airy cake. Its moist, nutty crumb and smooth, coffee-infused buttercream filling make it a crowd-pleasing favorite that’s perfect for special occasions or simply as a delightful afternoon treat with a cup of tea.

Whether you’re a seasoned baker or a beginner, following Mary Berry’s classic recipe will guide you to creating a show-stopping cake with minimal effort. With a few expert tips and a touch of patience, this cake will become a timeless addition to your baking repertoire, sure to impress all who take a bite.

Easy Recipe Variations For Mary Berry’s Walnut And Coffee Sandwich Cake

Mary Berry’s Walnut and Coffee Sandwich Cake is a delicious treat that combines the earthy flavor of walnuts with the rich depth of coffee, creating a cake that’s both indulgent and aromatic. While the classic recipe is a winner on its own, there are several creative ways to put a spin on this classic, making it adaptable to various tastes or dietary needs. Here are some easy recipe variations to try:

1. Gluten-Free Walnut and Coffee Cake

   For those with gluten sensitivities, simply replace the regular flour with a good-quality gluten-free flour blend. Many gluten-free flour mixes work well as substitutes in cakes, and a slight addition of xanthan gum (usually included in most gluten-free blends) will help with the cake’s structure and texture. Ensure you use gluten-free baking powder as well.

2. Vegan Walnut and Coffee Cake

   To make the cake vegan-friendly, swap the eggs for an egg replacer like flaxseed (mix one tablespoon of ground flaxseed with three tablespoons of water and let it sit for a few minutes until it thickens). Replace the butter with a plant-based butter alternative or oil, and use non-dairy milk, such as almond or oat milk, in place of regular milk. For the filling, opt for a dairy-free spread or whipped coconut cream to keep it fully plant-based.

3. Decadent Chocolate Walnut and Coffee Cake

   If you’re a fan of chocolate, add some cocoa powder to the cake batter for a rich, chocolatey twist on the classic recipe. You can mix in a few chunks of dark chocolate to make the cake even more indulgent. For the icing, a smooth ganache made from dark chocolate and dairy cream will add an extra layer of luxury and complement the coffee flavor beautifully.

4. Coffee and Walnut with a Toffee Twist

   Adding a toffee layer or using toffee-flavored buttercream will bring a caramelized richness to the cake. You can make your own toffee sauce by simmering butter, brown sugar, and cream until it thickens, and use it in the filling or drizzle it over the top of the cake. The combination of toffee, coffee, and walnut creates a truly indulgent treat.

5. Citrus-Infused Walnut and Coffee Cake

   For a fresh, bright note, consider infusing the cake with citrus zest. Orange or lemon zest works wonderfully with the deep, rich flavors of coffee and walnut.

   This variation lightens up the taste profile and brings a delightful contrast to the overall richness of the cake. You can also add citrus to the icing for an extra layer of flavor.

6. Coffee and Walnut Cake with Cream Cheese Frosting

   For a tangy, creamy alternative to the traditional buttercream, opt for cream cheese frosting. The slight acidity of the cream cheese balances out the richness of the cake, offering a smooth, velvety texture. The contrast between the tangy frosting and the deep coffee flavor is irresistible, and the walnuts provide the perfect crunch.

Best Practices To Store Leftovers

After indulging in Mary Berry’s Walnut and Coffee Sandwich Cake, you might find yourself with a few leftovers. Storing cake properly ensures it stays fresh and delicious for as long as possible. Here are some best practices for storing the cake:

1. Cool Before Storing

   Allow the cake to cool completely before storing it. If stored while still warm, condensation can form inside the container, which could make the cake soggy and less pleasant to eat.

2. Wrap Properly

   To preserve moisture and prevent the cake from drying out, wrap it tightly in plastic wrap or place it in an airtight container. You can also cover it with a layer of aluminum foil, ensuring that no part of the cake is exposed to air. This will help maintain the softness of the cake while also protecting it from any external odors.

3. Refrigeration (If Iced or Filled)

   If your Walnut and Coffee Sandwich Cake has been frosted or filled with cream-based fillings (like buttercream or cream cheese frosting), it’s best to refrigerate it to prevent the filling from spoiling. Be sure to store the cake in a container that is well-sealed to keep it from drying out.

4. Freezing for Longer Storage

   If you’re not planning on eating the leftovers within the next few days, freezing the cake is a great option. To freeze, wrap the cake slices tightly in plastic wrap, followed by a layer of aluminum foil to avoid freezer burn.

   When you’re ready to enjoy it again, simply defrost it in the fridge overnight or on the counter for a few hours before serving. Keep in mind that the frosting might lose a bit of its texture after freezing, but the cake itself should remain delicious.

5. Storing Unfrosted Cake

   If you have an unfrosted cake left over, it can last for about 3-4 days at room temperature if stored properly in an airtight container. If you’d like to store it for a longer period, you can freeze the cake layers and frost them once defrosted.

What Goes Well With Walnut And Coffee Sandwich Cake

Mary Berry’s Walnut and Coffee Sandwich Cake is a flavorful dessert, and pairing it with complementary items can elevate the experience. Whether for a special occasion or a casual afternoon tea, here are some great options for what to serve with it:

1. Fresh Coffee or Espresso

   Since the cake features coffee as a key flavor, it pairs wonderfully with a rich cup of freshly brewed coffee or an espresso. The boldness of the coffee enhances the deep coffee notes in the cake and provides a perfect contrast to its sweetness.

2. Fresh Berries

   Fresh berries such as raspberries, blueberries, or strawberries provide a tangy contrast to the richness of the cake. Their slight acidity and burst of freshness balance the dense texture of the walnut and coffee flavors, making the whole dessert experience more vibrant.

3. Whipped Cream

   A dollop of freshly whipped cream is a classic accompaniment to cakes like this. The light, airy texture of the cream provides a lovely contrast to the dense, nutty cake. You can sweeten the cream lightly and even add a dash of vanilla extract or a sprinkle of cinnamon for an extra layer of flavor.

4. Vanilla Ice Cream

   For an indulgent treat, serve a scoop of creamy vanilla ice cream alongside the cake. The cold, velvety ice cream contrasts beautifully with the warmth of the coffee and walnut flavors, and the combination is an irresistible dessert duo.

5. Tea or Iced Tea

   As is traditional with many British cakes, a hot cup of tea pairs perfectly with Mary Berry’s Walnut and Coffee Sandwich Cake. Earl Grey or English Breakfast tea works well with its subtle citrus or malty undertones. For warmer weather, a refreshing iced tea with a hint of lemon can balance out the richness of the cake.

6. Chocolate Truffles

   If you’re looking for an added touch of decadence, a few chocolate truffles on the side will take the flavor profile to another level. Rich, dark chocolate truffles offer an intense contrast to the coffee and walnut flavors, making the dessert feel even more luxurious.

Conclusion
