I love raspberries and wanted to use some in a cake. So I came up with this very easy Raspberry Chocolate Sponge.
It uses that tried and tested method of weighing eggs, in the shells, and using that same weight for the other ingredients. That works very well for a sponge cake. But for the recipe below I provide weights and cup measurements.
Basically, using the same weight for the sugar, the butter and a combination of flour and cocoa powder makes a very nice sponge cake. If you wish to check an interesting article about the ration of ingredients in baking you can read here.
For a plain sponge cake the flour will weigh the same as the eggs in the shells. However for a chocolate sponge we need to use some cocoa powder too. So 3/4 of the weight of the eggs is flour and the remaining 1/4 of the weight is made up with cocoa powder.
Of course the cake needs some leavening, in addition to the eggs, so a little baking powder is used as well.
Then, as a filling for the cake I used some raspberry as well as fresh raspberries along with a chocolate buttercream. Using fresh cream instead of buttercream is an alternative for those who might prefer that.
The recipe is actually very easy, even though there are several steps to it. It just takes a little patience which is rewarded by a very tasty treat.
The texture of the buttercream can be varied to personal taste, using different rations of butter, chocolate and icing sugar. Adding a little cream into it would make a richer buttercream too, if desired.
I baked my sponges for 22 minutes, until they were springy to the touch and just coming away from the sides of the pan.
Then I left them to cool for about 5 minutes before transferring them to a wire rack, where they cooled completely.
As the cakes cooled I made the buttercream by mixing butter and icing sugar and then some melted, cooled, chocolate.
I assembled the cake with that and the jam and raspberries between the two layers. Then it was time to taste it. The sponges were lovely and soft, with a nice chocolate flavour. The filling, too, was very good, the sweet but tart jam complementing the chocolate buttercream and then the lovely fresh raspberries made a great combination.
This is perfect for serving just as a slice of cake. But it is very good as a dessert too, with some whipped cream, or even ice-cream.
