The Best Coffee and Walnut Cake Recipe

If you’re bored of the usual vanilla or chocolate, you have to try this classic British coffee and walnut cake recipe!

I promise, it’s super easy and crazy-tasty.

The cake itself is tender ad moist with the perfect amount of coffee taste. Plus, the frosting is silky smooth and tastes just like a latte.

How To Decorate a Coffee and Walnut Cake

One of the easiest ways to decorate this cake is to simply divide the frosting in half. Then, trim the bottom cake so it is flat and gently spread the frosting over the surface, stopping at the edges.

Put the top cake in place and add the rest of the frosting to the top. Then, carefully spread it to the edges, and you’re done!

Want something a little nicer? Use a butter knife, starting at one side, and gently move back and forth, from edge to edge, to create delicate ridges over the top.

Want to use a piping bag? Great! Try adding some swirls around the border of the bottom cake. You can even just add blobs, so long as they run around the whole edge of the cake. Next, fill with frosting, spreading it out, so it’s even.

One of the most popular ways to decorate this cake, though, is to cover it with finely chopped walnuts - all over the top and the sides. With this method, you don’t need to worry about being neat and tidy. The nuts will hide any imperfections.

Of course, that will be more expensive, so you could just chop the nuts roughly and scatter them over the top.

A drizzle of caramel would look extra decadent, or chocolate shards really make this cake pop!
