Take your lined springform and spread on about 2-3 tablespoons of the yellow batter on the bottom. Make sure you spread the batter evenly. Bake this first layer under the grill/broiler for a few minutes. You’ll have to check how long it takes to bake the layer usually about 1-3 minutes, depending on your grill/broiler. Use a cake tester to test if the cake is done. Once the yellow layer is done, take it out of the oven and spread 2-3 tablespoons of the brown batter on the top of the first layer. Bake the second layer under the grill and spread 2-3 tablespoons of the batter onto the brown layer.
