Tips For Best Results
- Use room temperature ingredients for a smoother batter.
- Don’t overmix the batter to keep the cake tender and light.
Step 1
Lightly heat your oven to 300°F (150°C). Grease and flour a 12-cup Bundt pan to make sure the cake doesn’t stick. In a large bowl, beat together the sugar and margarine until the mixture is light and fluffy. Then, add the eggs one at a time, mixing briefly after each addition. Stir in the sour cream and vanilla extract until everything is well combined.
Step 2
In another bowl, sift together the flour, baking soda, and baking powder. Add this dry mix to the wet ingredients in four parts, beating well after each addition until the batter is smooth.
Step 3
Scoop out about 2 ½ cups of the batter into a small bowl and mix in the cocoa powder until it turns a rich chocolate color. Fold in the white chocolate chips. Then, stir the dark chocolate chips into the remaining plain batter.
Step 4
To assemble, pour half of the plain batter into the Bundt pan, then add all of the chocolate batter on top, and finish with the rest of the plain batter. Bake for about 1 hour and 20 minutes, or until the top is golden and a knife inserted in the center comes out clean.
Step 5
Let the cake cool for about 20 minutes on a wire rack. Run a knife around the edges to loosen it, then carefully flip the cake onto a plate or cooling rack. Enjoy!
