Prep your matcha by dissolving/whisking 2x packets in 3-4 tbsp of hot water. Reserve a tiny bit of the matcha powder to dust the top of the finished caked.
Bake both cakes according to package, adding/whisking in the prepped matcha, lemon zest and squeezed lemon juice when you first combine the wet ingredients according to the box instructions. Once cakes are baked, let cool and refrigerate for 1 hour.
Add vanilla frosting to the top of one of the cakes, to serve as the in-between layer.
Mash 1 cup raspberries in a bowl, then spread over the top of the already-frosted cake layer.
Carefully stack currently unfrosted cake on top of the raspberry + frosted-cake layer by flipping the unfrosted cake so that the flat bottom now becomes the top of the cake.
Add frosting to cover the outside of both layers/the fully-stacked cake, then use a cake smoother tool to smooth out the frosting.
Add about 10-12 raspberries to decorate the top, I like to outline the edge of the cake with them. Then use a strainer or duster to dust the top of the cake with the leftover matcha powder. Enjoy!
