What is the coffee & walnut sponge cake?

So, what’s the deal with Mary Berry’s Coffee & Walnut cake? It’s a classic British dessert that brings together a light and fluffy coffee-infused sponge with loads of chopped walnuts. And we can’t forget about that dreamy coffee-flavoured buttercream icing that gets slathered between the layers. Seriously, it’s like a creamy, velvety masterpiece!

To whip up this delightful cake, you’ll need self-raising flour, unsalted butter, caster sugar, eggs, instant coffee granules, walnuts, and milk. The method is a piece of cake. You start by creaming the butter and sugar, then add in the eggs, fold in the dry stuff and coffee, and finally mix in those heavenly chopped walnuts. Pop it all into cake tins, bake ’em ’til they’re golden and smell like heaven, and you’re good to go!

Ingredients

  • Unsalted butter – 100g/3½oz softened unsalted butter. We would also need around 1 teaspoon for greasing.
  • Caster sugar – 100g/3½oz
  • Eggs – 2 free-range eggs.
  • Self-raising flour – 100g/3½oz
  • Baking powder – ½ teaspoon
  • Coffee granules – 1 tablespoon of coffee granules dissolved in 1 tablespoon of boiling water

How to make Mary Berry’s coffee and walnut cake recipe

  1. Warm the oven to 180C/160C Fan/Gas 4.
  2. Butter the two 18cm/7inch sandwich tins and line each base with baking paper.
  3. Mix the butter, sugar, eggs, flour, baking powder, and coffee in a mixing bowl using an electric hand whisk if you have one handy. Combine until smooth.
  4. Fold gently the walnuts.
  5. Split the mixture evenly between the tins.
  6. Smooth out the surface with a spatula or the back of a spoon. We want it nice and level.
  7. Place those tins in the oven and let them bake for about 15-20 minutes keeping an eye on them. Check when to pull them out by inserting a skewer.
  8. Pull them out to cool for around 5 minutes when the skewers come out clean.
  9. Gently loosen the edges by using a rounded butter knife and gently loosen the edges.
  10. Carefully turn the cakes out onto a wire rack.

For assembling the coffee and walnut cake.

  1. Pick the cake with the best-looking top.
  2. Place the other cake upside-down on a fancy serving plate and cover it with half of the coffee icing.
  3. Plop the other cake right on top and press gently.
  4. Cover the top of the cake with the coffee icing and get creative with some walnut pieces as decoration.
  5. Serve and enjoy the scrumptiousness!

Tips

  • Level the cake batter in the tins to ensure even baking and a uniform texture.
  • Allow the cakes to cool completely before frosting to prevent the icing from melting.

Variations

  • Coffee & walnut cake with espresso flavour: Use espresso from a coffee machine for a robust coffee flavour.
  • Coffee & walnut cake with a nutty kick: Toast the walnuts before adding them to the batter to enhance their nuttiness.
  • Gluten-Free coffee & walnut cake: Substitute the self-raising flour with gluten-free flour blend and ensure all other ingredients used are gluten-free.
  • Vegan coffee & walnut cake: Replace butter with vegan margarine or coconut oil, use a plant-based milk, and replace eggs with a suitable egg substitute like applesauce or flaxseed meal.
  • Mocha coffee & walnut cake: Add cocoa powder to the cake batter to create a delicious mocha flavour. You can also incorporate chocolate chips into the cake for extra richness.
  • Coffee & walnut cupcakes: Transform the recipe into delightful cupcakes by portioning the batter into cupcake liners. Adjust the baking time accordingly.
  • Boozy coffee & walnut cake: Add a splash of your favourite liqueur, such as Irish cream or coffee liqueur, to the cake batter or frosting for a grown-up twist.
  • Coffee & walnut loaf cake: Use a loaf tin instead of sandwich tins for a more rustic presentation. Adjust the baking time accordingly.
