German Marble Cake
A buttery vanilla cake is divided into two portions.One portion is enriched with cocoa to create the chocolate batter.The vanilla and chocolate mixtures are layered in a prepared Bundt pan.A fork gently swirls the batters together to create the marble pattern.The cake is baked until golden and a skewer comes out clean.After cooling, it is dusted with powdered sugar and served in slices.
Ingredients
For the Vanilla Batter
- 250 g unsalted butter, softened
- 200 g granulated sugar
- 1 packet vanilla sugar or 2 teaspoons vanilla extract
- 4 large eggs, room temperature
- 300 g all-purpose flour
- ¼ teaspoon salt
- 1 teaspoon lemon zest, optional
- 120 ml milk
For the Chocolate Batter
- 25–30 g unsweetened cocoa powder
- 2 tablespoons milk
- 1 tablespoon sugar, optional
For the Pan
- 1 tablespoon softened butter
- 1–2 tablespoons breadcrumbs or flour
For Finishing
- Powdered sugar, for dusting
Instructions
Prepare the Oven and Pan
- Preheat the oven to 175°C / 350°F. Generously butter a 9- or 10-inch Bundt or Gugelhupf pan. Sprinkle it with breadcrumbs or flour, making sure the inside is well coated.
Cream the Butter and Sugar
- Place the softened butter in a large mixing bowl. Beat until smooth and creamy. Gradually add the sugar and continue beating until the mixture becomes lighter and fluffy.
Add the Eggs
- Add the eggs one at a time, beating well after each addition. Mix in the vanilla sugar or vanilla extract and lemon zest if using.
Add the Dry Ingredients
- Whisk together the flour, baking powder, and salt. Add the dry ingredients to the butter mixture alternately with the milk. Mix only until a smooth batter forms. Avoid overmixing.
Create the Chocolate Batter
- Transfer approximately one-third of the batter to another bowl. Add the cocoa powder and 2 tablespoons of milk. Mix gently until evenly combined. If the chocolate mixture seems noticeably thicker than the vanilla batter, add another small splash of milk.
Layer the Batters
- Spoon about half of the vanilla batter into the prepared Bundt pan. Add the chocolate batter over it, then finish with the remaining vanilla batter.
Bake
- Place the pan on the middle oven rack and bake for approximately 45–55 minutes.Insert a wooden skewer into the thickest part of the cake. If it comes out clean or with only a few moist crumbs, the cake is ready.
Cool
- Remove the cake from the oven and allow it to rest in the pan for approximately 10–15 minutes. Carefully turn it onto a cooling rack and allow it to cool completely.
Finish and Serve
- Once completely cool, dust generously with powdered sugar. Slice and serve with coffee, tea, or hot chocolate.
Notes
- Use room-temperature ingredients for a smoother, more uniform batter.
- Do not overmix after adding the flour because this can make the cake dense.
- The chocolate batter should have a consistency similar to the vanilla batter.
- A Bundt or Gugelhupf pan gives the cake its traditional German appearance.
- Grease every groove of the pan carefully to make releasing the cake easier.
- Avoid opening the oven frequently while the cake is baking.
- Let the cake cool before slicing for cleaner and more attractive swirls.
- Store the finished cake covered at room temperature for about 2–3 days.
