ASSEMBLING
Place the first cake layer on your serving dish or cake board on your turntable. If you don’t have a turntable, don’t worry, you can easily decorate the cake without it.
Add 2 big scoops of buttercream and with an offset spatula, even it out. Then add 2-3 tablespoon of blueberry jam and even it out. Leave the outer edge of the cake free so the blackberry jam doesn’t spill out. Repeat the process for the next cake layer. Add the last cake layer and cover the whole cake in a thin crumb coat.
4-6 tablespoon blackberry jam
Place it in the fridge for 20 minutes, so it’s easier to cover the whole cake in the remaining buttercream.
Add the remaining buttercream, and even it out over the cake. Finally, decorate with fresh blackberries and lemon slices.
