Easy homemade marble bundt cake recipe! This moist chocolate and vanilla swirl bundt cake is so simple to make.
This Chocolate Swirl Bundt Cake is so super moist! It has a rich chocolate cake that contrasts perfectly with the tender vanilla cake. And when it's topped with chocolate ganache, it tastes like one of my favorite foods - a cake donut.
This yummy bundt cake is perfect for birthdays or any other celebratory occasions (like a Tuesday night).
How to make marble bundt cake
With bundt cakes, it's important to grease and flour the pan well. Otherwise the cake can stick. Pan release works really well for greasing bundt pans.
Beat butter and sugar together in a large mixing bowl until well-combined. Mix in the eggs one at a time and vanilla extract.
Mix in the buttermilk until well-combined. Add the flour, baking powder, and salt. Stir in just until combined.
Remove part of the vanilla batter to a separate mixing bowl. Mix in the cocoa powder and milk.
Stir the remaining vanilla into the vanilla batter. Drop a scoop of vanilla batter into the bundt pan and top with a scoop of chocolate batter.
Repeat alternating batters. Continue to drop the scoops of batter on top of each other.
Do not stir. To level out the batter, gently tap the pan a few times. Bake.
- I use a baking spray with flour in it or pan release to coat the bundt pan. You can also grease and flour the pan. Either way, generously grease the pan to avoid sticking.
- Cake flour: Cake flour helps to make this cake tender. To make a cake flour substitute, you can use this recipe.
- Buttermilk: You can use regular or low-fat buttermilk in this recipe. If you would like to make a substitute, you can use this recipe.
- Chocolate ganache: I use a simple chocolate ganache on top of this cake.
- If you'd like to make mini bundt cakes instead of a regular bundt cake, this cake will make 12 1-cup bundt cakes. Reduce the baking time to about 20-25 minutes.
