A sweet treat today, one for the coffee lovers!
The boys devoured this so it isn’t too strongly flavoured with coffee and it is gluten and nut free.
Cuts into 8 very generous slices.
Ingredients
6 eggs
150g caster sugar
2 teaspoons instant espresso powder
50g cocoa powder
ICING
250g icing sugar
125g salted butter
2 teaspoons instant espresso powder
15mls boiling water
Method
Preheat the oven to 180 degrees Centigrade. Line a baking tray, 38x25cm, with baking parchment, folding it right into the corners as the cake batter is too light to weigh it down.
In a large bowl, whisk the egg whites with an electric whisk to stiff peaks, add 50g of the caster sugar and whisk in until the whites are shiny.
In another large bowl, using the whisk that you used for the whites, whisk the egg yolks, remaining sugar and coffee powder until really thick, creamy and the powder has dissolved. Sieve the cocoa over the bowl and fold in.
Now, fold a third of the whites into the yolk very gently. Once combined repeat with another third and then with the remaining third.
Spoon the batter, spreading it evenly up to the edges, onto the baking tray and bake for 20 minutes.
While the cake is baking boil the kettle.
In a food processor, whizz the icing sugar to remove any lumps, add the butter and whizz until creamy in the processor.
Measure out the coffee powder into a small cup, add the boiled water and stir to combine.
Slowly pour this coffee into the processor with it on to combine. Scrape down the sides and process again. You may neeed to do this a few times to get all of the coffee incorporated.
Once the cake is ready, remove from the oven and let it sit for five minutes.
Cover the cake with a clean tea towel and invert so you have the parchment up. Peel the parchment off.
Now, roll the cake, including the tea towel, skinny end to skinny end. Allow to sit and cool with the tea towel still in situ.
Once the cake has cooled, unroll gently, remove the tea towel, spread the inside of the roll with the icing and roll back up.
Sift a little icing sugar over and serve.
