Instructions

Working time approx. 15 minutes; Cooking/baking time approx. 1 hour; Total time approx. 1 hour 15 minutes

Cream the butter with the powdered sugar, cornstarch, rum, salt, vanilla, and lemon zest until fluffy. Gradually stir in the egg yolks. Mix the flour with the baking powder and stir in alternately with the milk. Beat the egg whites until stiff peaks form, slowly adding the sugar. Fold the egg whites into the batter. Pour 2/3 of the batter into a greased bundt cake pan. Mix the cocoa powder into the remaining batter and pour over the light-colored batter. Use a fork to spiral through the batter to combine the two batters. Preheat oven to 180°C and place the cake on the middle rack. Bake for approx. 60-70 minutes (use a skewer to test if it is dry). Remove from the oven and let rest in the pan for 10 minutes. Turn the cake out onto a wire rack to cool. Decorate the finished cake with glaze or powdered sugar, as desired.
