Instructions

Banana Cake

Preheat oven to 350℉. Grease two 9" cake pans, line with parchment paper, and grease the parchment.
Beat together butter and brown sugar.
Add the eggs and vanilla and mix until well combined.
Mix in the mashed banana.
Add the dry ingredients and mix until just incorporated.
Divide batter between the two prepared cake pans, about 900g of batter per pan.
Bake approximately 35 minutes, until the cakes are golden brown and the center of the cake is set. Cool completely.

Banoffee Cake Assembly

Place one layer of cake onto a serving dish and spread a thin layer of dulce de leche onto the cake layer.
Pipe a border of dulce de leche around the edge of the cake to form a barrier using a piping bag without a tip or a strong zip-top bag with a corner cut off.
Place a single layer of banana slices inside the barrier.
Place the other layer of cake on top.
Beat the cream and brown sugar until stiff peaks form, then spread over the cake. Slice and enjoy!

Notes

Use as much or as little of the dulce de leche as you'd like. And if you decide to skip the fresh bananas, the dulce de leche barrier around the edge isn't needed - just spread a layer as thick as you'd like!

This cake can also be made into three 8" layers or four 6" layers.
