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
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.
Tips
Tips- I use a baking spray with flour in it 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.

Can I make this in a 6 bundt pan? Is there a need to reduce the recipe?how about the cooking time? Thank u, dying to try this delish recipe!! 😊
Kate says
Hi! This recipe is meant for a 10-12 cup bundt pan. If you’re using a 6 1-cup mini bundt pan, you should be able to halve the recipe. I would start checking around 15-20 minutes on mini bundts. Hope that helps!
SN says
I made this recipe and loved it, thank you!
Kate says
You are very welcome! Glad you liked the cake. =)
Candy says
Reply for poster above wanting bake time for small Bundt cakes…
this cake will make 12 1-cup bundt cakes. Reduce the baking time to about 20-25 minutes.
Denise says
Perhaps I was blinded by the gorgeous site of cake, but was there a time listed for baking the mini-Bundt cakes? I’m sure the 50-60 minute time frame is for a ‘regular’ 12-cup Bundt pan.
Kate says
Thank you! Yes, you’re correct about the bake time. For the mini-bundt cakes, the bake time is 20-25 minutes. If you have any other questions, please feel free to ask!

Yum!
Jackie says
Hi Kate
You mentioned there was bittersweet chocolate in the recipe, but it is not listed in the ingredient’s list.
Kate says
Hi Jackie,
Sorry for the confusion! The mention of the bittersweet chocolate swirl was referring to the flavor of the chocolate swirl in the cake (i.e. a not-so-sweet chocolate swirl). The cake doesn’t contain any actual bittersweet chocolate.

This is such a beautiful little cake! Back in Utah we had a little bundt cake shop, but I haven’t been able to find anything quite like it since we moved. But I fell in love with little marble bundt cakes, and now I can make my own! Thanks!
Kate says
Was the name of the shop something like “Nothing Bundt Cake”? My sister brought me a little red velvet cake from that shop for my birthday a couple years ago, and it was so good!! I’m glad that you can make your own now, though! It’s always fun to be able to make something that you enjoy. =)
