All through Lockdown we have had THE best weather here in the UK. It would seem though, that as Lockdown is being eased the good weather is easing too. The day I recorded the video for this recipe it was windy, blustery, raining but still a bit warm. I figured weather like that needed comfort food, and you can’t get much more comforting than a good Coffee and Walnut Cake.

The Best Coffee and Walnut Cake Recipe

Coffee and Walnut is a great classic cake flavour in the UK. It was always a favourite in our Tea Room, and most popular with the men…..I don’t know why. Maybe its the strong flavour, but it’s definitely a male classic.

The Easiest Recipe to Remember

This Coffee and Walnut Cake is a finely balanced piece of baking, but even in the absense of a set recipe it is actually one of the easiest to remember how to make.

It all starts with the weight of the eggs, and because of that it scales really well. You can make a small 6″ layer cake, like I have here, or a 4 layer, 12″ wedding cake tier. It’s just the difference between 2 eggs and 18 eggs – the way you work out the other ingredients is exactly the same.

The Best Coffee and Walnut Cake Recipe

Start by weighing your eggs, in their shells, and use the same for all the other ingredients. So for example is your eggs weight 150gms in their shells, you use 150gms of butter, sugar and flour too.

When you break the eggs you’re going to loose the weight of the shell, so you make up for that by adding the coffee. So when you break the eggs they may then weigh 120gms, which means you put in 30gsm of coffee to get the weight back.

If you don’t like walnuts, that’s no bother, just leave them out. You could add pecans if you prefer. Or if you’re looking for a different flavour sensation you could use chocolate buttercream for a Mocha Cake – again, another big hit in the Tea Room.
