Marble Bundt Cake

Why You Will Love This Cake

One Batter: Even though this cake has two flavors, you only need to make one batter!
Moist: Butter, oil and buttermilk give this cake so much moisture.
Chocolate & Vanilla: Not only is this such a pretty cake with the marbling, but you get the best of both worlds with the two flavors.

Ingredient Notes

Full ingredient measurements and instructions can be found in the recipe card below.

Butter: I always use salted butter, but unsalted is fine also.
Oil: I've used both canola and coconut with this. If using coconut make sure its melted.
Vanilla Bean Paste: I love the taste and little flecks this adds to the cake, but you can use vanilla extract instead if you prefer.
Flour: If you have cake flour I would suggest using it, but all-purpose or gluten free will work great too!
Buttermilk: Using a full-fat buttermilk is always preferred because the more fat, the more moist the cake will be.
Cocoa Powder: I love using dutch process for a rich chocolate flavor.

Expert Baking Tips

When making cakes, having room temperature ingredients is very important for helping both the rise of the cake, and that the ingredients mix properly.
This can also be made into a two layer 8-9 inch cake. You will need to bake for about 28-33 minutes.
If you prefer you can skip the chocolate glaze and dust with powdered sugar or use this vanilla glaze.

Storing & Freezing

This marble bundt cake may be stored at room temperature in an airtight container. You can also wrap it in tinfoil, as this will help the glaze from getting too sticky and moist.

This cake freezes well for up to 3 months. Thaw overnight in the refrigerator and allow to come to room temperature before serving. You can also freeze individual slices in ziplock bags for an easy on the go snack.
