Moist, fluffy, and addictive are the best to describe this Mary Berry’s coffee and walnut traybake, a cake you would love to have for your afternoon cuppa. 

Those who love baking will almost definitely know who Mary Berry is, the baking queen from the UK whose recipes are failproof.

Of all her baking recipes, I love her cake recipes the most.

And because I love coffee, my favorite cake recipe is the coffee and walnut cake recipe. I found it in Mary Berry’s Fast Cakes recipe book. 

The coffee cake has coffee in it. You dissolve your favorite instant coffee granules with a little water and use it as your coffee flavoring.

This traybake recipe will give more ideas for moms with school-age children so that you can make this coffee and walnut traybake next time you have to bake a cake for your school fete. I promise you it will be so popular.

The cake has a smooth sponge texture, and it is very moist. The coffee buttercream is smooth and creamy with the right sweetness that won’t make you sick.

Lastly, the savory walnuts give the sweet cake and buttercream a nice finish. 

Versatile recipe

Although this recipe calls for a rectangle bake tin to make the cake a traybake, you can use a different cake tin. Then, you can turn the cake into an ordinary coffee and walnut cake.

This recipe is sufficient to be divided into two 8-in round cake tins. So feel free to use this recipe for your next coffee and walnut cake.

And if you have a nut allergy, you can omit the walnuts and enjoy it as a coffee cake. 

What you need to make coffee cake

Apart from the instant coffee granules and walnuts, this cake requires basic items to make a sponge cake.

ingredients for coffee and walnut cake.

In detail, there are 11 ingredients you need:

  1. Instant coffee granules.
  2. Baking spread.
  3. Caster sugar.
  4. Self-raising flour.
  5. Baking powder.
  6. Eggs.
  7. Milk.
  8. Butter
  9. Icing sugar.
  10. Walnut.
  11. Hot water.

I appreciate that the baking spread may not be easily available to you. In this case, you can substitute with margarine. 

However, I must warn you that margarine tends to have a higher fat content than baking spread. So, the baked goods may be slightly denser or dryer.

Rest assured, though, that your coffee cake will still be delicious. 

Fast method

What I love about this recipe is the easy and simple method that doesn’t take much time. It took me about 10 minutes to make the batter and another 5 minutes to whip the coffee buttercream.

The baking itself took about 35 minutes. But I had to leave the cake to cool down before completely putting the frosting on. This took me around half an hour. 

I had the cake ready in about 1 hour and 20 minutes. I think this was fast. Considering the cake has frosting on it. 

Tips for making a moist coffee cake

  • Baking is like doing chemistry. Every item involved will affect each other according to its weight and value. So measuring in precision is important, as well as the temperature of your oven and the baking time. 
  • Fresh ingredients. Ensure your self-raising flour, baking powder, milk, and eggs are fresh. Because these items can go stale and off. You want them of their best quality so they can create the nice cake you want.
  • Whisk your cake batter until everything is mixed well, and you end up with a creamy and pale-colored batter.

How to store your cake

Ideally, you keep your coffee and walnut cake in the fridge if there is any leftover. 

However, the cold temperature will dry the cake texture no matter how tightly you wrap or keep your cake in a food container. So bear that in mind.

I personally store my cake in a cake container with a tight lid on it and leave it on my kitchen worktop. Luckily, cakes usually last only for a few days in our household.

If you need to freeze the cake, you can put the cake in a tight-lid container and store the container in a freezer. It keeps well for about 2 months. 

Once your cake thaw, consume it within a few days, and you must not refreeze it.

Instructions

  • Preheat the oven at gas 4/ 180℃/ 356℉.
  • Prepare a 30 x 23cm (12 x 9 in) bake tin, grease its side and line it with a greaseproof baking paper. 
  • Dissolve two tablespoons of instant coffee granules with two tablespoons of hot boiling water from the kettle. Let it cool while you get the other ingredients ready.
  • In a mixing bowl, place the self-raising flour, caster sugar, baking powder, baking spread or margarine, eggs and milk.
  • Use a handheld mixer or a standing mixer to beat the ingredients in the bowl until you get a smooth batter. 
  • Then add the coffee mix into the batter. Mix well.
  • Pour the batter into the traybake and level the top evenly. 
  • Bake for about 30-35 minutes at gas 4/ 180℃/ 356℉ until the top springs back when you touch the cake and it has shrunk from its sides a little. 
  • Let the cake cool down for about 15 minutes before taking it out of the tin.
  • Meanwhile, mix one tablespoon of instant coffee granules with one tablespoon of hot water from the kettle. Leave it to cool.
  • Beat the butter, icing sugar, milk and coffee mixture until smooth and fluffy.
  • Spread the buttercream on top of the coffee cake and scattered the chopped walnuts over. Cut the cake into generous 16 pieces.

Notes

  • The baking spread is similar to margarine but with lower content of fat. If the baking spread is not available to you, using margarine or butter can be an option. Just bear in mind if you use butter your cake may be slightly denser due to the fat. But I can assure you it will be equally delicious.
  • In the case self-raising flour is not available to you, mix 1 tsp of baking powder with every 3.5oz/ 100 gr all-purpose flour/ plain flour. Use a handheld whisk to stir and mix the flour.

    1. Yeah, one doesn’t need to be a coffee drinker to love this coffee cake. I’m glad you find it easy to make and yummy to eat.

  9. Chris Stiles says:

    Looks like it will be a nice cake but there’s no mention of butter on the cake mix part of the video. Doesn’t say when to put it in. So my thirteen year old is now mixing it in after he’s done everything else.

    1. Apologies! I definitely missed that. I have updated the recipe and thank you for pointing that out. Your thirteen old did no mistake. The cake should turn out fine. Because this coffee cake is like a dump-everything cake. As long as all the ingredients are there, it should be ok. Again, thank you for letting me know.
