I made this cake for my friend Mia's birthday (hence why my pictures say Mia on the cake). The sponge was moist and dense like a brownie, and perfectly complemented the rich chocolate buttercream icing and crunchy finger biscuits! You could add fruit such as strawberries or raspberries in the middle and it would look very colourful. You could also top it with marshmallows, or with more chocolate sweets such as Malteasers, or just decorate it with tons of candles!
Love this recipe...made it twice now. Second time swapped the chocolate in the icing for white chocolate. It worked really well but was harder to work with than the dark chocolate icing - 11 Jun 2015
