Marble Cake with Swirls (Print Version)

# Ingredients:

→ Cake

01 - 275 g unsalted butter or baking spread
02 - 275 g caster sugar
03 - 275 g self-raising flour
04 - 5 medium eggs
05 - 25 g cocoa powder
06 - 2 tbsp whole milk
07 - 1 tsp vanilla extract

→ Buttercream

08 - 200 g unsalted butter, room temperature
09 - 400 g icing sugar
10 - 25 g cocoa powder
11 - 1 tsp vanilla extract
12 - Sprinkles for decoration

# Instructions:

01 - Preheat your oven to 180ºC / 160ºC fan and line two 8-inch cake tins with baking parchment. Beat butter and sugar together until light and fluffy.
02 - Add self-raising flour and eggs to the mixture and blend until incorporated. Divide the batter evenly between two bowls.
03 - Mix cocoa powder and milk into one bowl, and vanilla extract into the other. Mix each bowl thoroughly.
04 - Dollop the two batters alternately into the prepared tins and swirl gently with a skewer or knife to create a marbled effect.
05 - Bake in the preheated oven for 30-35 minutes, or until a skewer inserted in the center comes out clean. Allow the cakes to cool completely.
06 - Whip the room-temperature butter for a few minutes to aerate. Gradually add icing sugar and beat until light.
07 - Split the buttercream into two bowls. Add cocoa powder to one bowl, and vanilla extract to the other. Mix each thoroughly.
08 - Lay a large piece of cling film flat. Place the two buttercream flavors in lines down the center. Roll into a sausage shape, snip the end, and insert into a piping bag.
09 - Pipe the buttercream onto the cooled cakes in your desired pattern. Decorate with sprinkles as a finishing touch.

# Notes:

01 - This cake remains fresh for 3-4 days once baked and can be frozen for up to 3 months. Consider flavor customizations such as orange for the chocolate batter or lemon for the vanilla batter.
