Classic Marble Butter Cake by Tiimakitchen

Ingredients

• 200 g (1 cup) unsalted butter, softened
• 200 g (1 cup) granulated sugar
• 3 large eggs
• 250 g (2 cup) all-purpose flour
• 2 tsp baking powder
• 1/2 tsp salt
• 120 ml (1/2 cup) whole milk
• 2 tsp vanilla extract
• 2 tbsp unsweetened cocoa powder
• 1-2 tbsp milk (extra, for chocolate batter)

Instructions

1. Preheat your oven to 180°C (350°F). Grease and flour a 9x5 inch (23x13 cm) loaf pan or an 8-inch (20 cm) round cake pan.
2. In a large bowl, cream together the softened butter and granulated sugar with an electric mixer for 3-5 minutes, until light and fluffy.
3. Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Scrape down the sides of the bowl as needed until ready to serve.
4. In a separate medium bowl, whisk together the all-purpose flour, baking powder, and salt over medium heat until heated through, about 5 min.
5. Gradually add the dry ingredients to the wet ingredients in three additions, alternating with the milk. Begin and end with the dry ingredients, mixing until just combined after each addition. Be careful not to overmix.
6. Divide the batter evenly into two separate bowls. Stir 2 teaspoons of vanilla extract into one bowl of batter until ready to serve.
7. Into the second bowl, stir in the 2 tablespoons of unsweetened cocoa powder. If the chocolate batter appears too thick, add 1-2 tablespoons of extra milk until it reaches a similar consistency to the vanilla batter.
8. Spoon alternate dollops of vanilla and chocolate batter into the prepared cake pan. Once all batter is in the pan, use a butter knife or skewer to gently swirl the two batters together to create a marbled effect. Do not overmix the swirls until ready to serve.
9. Bake for 45-55 minutes, or until a wooden skewer inserted into the center of the cake comes out clean. The top should be golden brown and spring back when lightly touched.
10. Allow the cake to cool in the pan for 10-15 minutes before carefully inverting it onto a wire rack to cool completely before slicing and serving.
