I had been saving these coffee granules ready for a cake for S for ages. It's his birthday tomorrow, coffee and nuts for his cake is perfect (I hope) - I wanted to make a classic coffee and walnut cake and make it as good as I could. For the cake part I used approximately
this recipe (ramping up the coffee but no other real changes), then I added syrup.
I thought I'd try a cream cheese icing, inspired by
Delia's coffee and walnut cake and by the icing Seb made for my birthday cake (at which time I discovered that Trader Joe's carries vegan cream cheese and it really isn't that bad - doesn't even have palm oil in it).
For the cake:
1 cup fake milk
1 tsp cider vinegar
1¼ cups plain flour
2 tbsp cornstarch
¾ tsp baking powder
½ tsp bicarbonate of soda
½ tsp salt
⅓ cup veg oil
¾ cup sugar
2 tsp coffee granules dissolved in 2 tsp hot water
¼ tsp vanilla essence
¼ cup walnut pieces
For the syrup:
1 tsp coffee granules
2/3 oz demerara sugar
28 ml boiling water
For the icing:
2 packages (~500g total) vegan cream cheese
2 heaped tbsp icing sugar
1 tbsp powdered coffee granules
1 tbsp maple syrup
1/4 tsp cider vinegar
To decorate:
More walnut pieces plus 10 walnut halves, toasted
Heat oven to 350F. Line the bases of two cake tins. Mix the fake milk and vinegar and set aside to curdle.
In a medium bowl, beat together the fake milk mixture, oil, sugar, coffee and vanilla. In a separate bowl, mix the flour, cornstarch, baking powder,
bicarb, and salt with a fork. Add wet to dry and mix until no large lumps
remain, adding the walnut pieces in the final few strokes. Divide the mixture between the cake tins and bake for ~30 min.
While the cakes bake you can make the syrup - put the sugar and coffee in a small bowl or mug, pour the boiling water over and mix until the sugar and coffee are dissolved. When the cakes come out of the oven, while they are still hot, prick all over with a skewer and then spoon the syrup evenly over the surface. Leave to cool.
While the cakes cool you can make the icing. Put the cream cheese, powdered coffee granules (I crushed them in small pestle and mortar) and sugar in a bowl and beat together. Taste and add maple syrup, cider vinegar and/or some fake milk if you feel like it needs more sweetness or acidity, and until a good spreading texture is obtained. Refrigerate until needed (if you're not planning to assemble as soon as the cakes are cool).
Bring the icing to room temperature before assembling the cake. Take the cooled cakes out of the tins and strip off the backing papers. Place one on a plate, spread with ~ half the icing and sprinkle with some toasted walnut pieces. Then put the other cake on top, spread the rest of the icing over it, and arrange the walnut halves on top. I used the finer walnut crumbs to make the letter S on top too. Keep refrigerated if not eating right away.
At first I thought the cake layers were a bit thin, but by the time I'd piled them up with the icing and toasted nuts it ended up as a good total cake thickness, so perhaps not (although, final word, would probably increase cake recipe by half as much again if making again). The icing I thought was very successful - nice soft brown colour, good creamy consistency that sat up well by itself, not too sweet. So I was happy using more than usual to layer up the cake as it didn't overpower with sweetness or drip off the edges. Instead, it provided a definite coffee hit to mix in with the toasty walnut flavour. All in all, a pretty successful birthday cake - definitely suitable for breakfast (when we always end up eating birthday cake) as it is loaded with coffee and not very sweet! One thing: I think both the syrup and the addition of walnuts to the cake batter are perhaps not really necessary and the cake would probably be just as good without.
