Tiramisu Cake Lisa Thompson January 5, 2018 The beginning of something beautiful. Pillowy sponge cake delicately flavored with almond and vanilla extracts to mimic a lady finger biscuit. This technique involves slicing the sponge into three equal strips, spreading each with filling (in this case, a coffee/Kahlua soak and mascarpone buttercream), then rolling each strip into the next (think "snowball effect"). This tiramisu-inspired beauty gets decorative dollops of buttercream and a shower of black cocoa powder for deep, chocolatey richness and a little bit of drama.
