I wasn’t sure how this banana bundt cake was going to shake down, but how bad could it be? Vanilla, banana, and chocolate all go together in a banana split, right? And the buttermilk gives it a tang that helps cut the sweetness. I’m pretty sure that banana buttermilk bundts will be happening in my house more often than not!

When I am desperate to bake something, whether it’s because I need:

a) the stress relief of baking something, anything just let me bake!

b) a sweet tooth fix

c) both are the same thing, no?

I usually end up rummaging through my tickle trunk of ingredients and see what my mind comes up with. This last time I had buttermilk in the fridge, chocolate chips, and ripe bananas in my freezer.

Tips and Tricks for Making Banana Bundt Cake

  • The buttermilk really adds not only a great tang to the cake but also makes it a super moist cake.
  • Use really ripe bananas for the best flavor possible
  • You need to bake bundt cakes until a cake tester or toothpick is inserted in the middle AND in the cake beside the hole in the middle comes out clean. The area by the hole in the middle can take a while to bake. If it falls, it’s because you didn’t bake it completely so always test!

This was a great textured bundt, moist from the buttermilk, sweet with banana flavor and the chocolate makes it so decadent! And that chocolate satin glaze takes this far beyond a boring banana bundt! Add some fresh bananas on top for decoration right before you serve it and you have something ten times more tasty than normal banana bread!

However, if you are looking for banana bread, try my Mom’s Best Banana Bread. It actually IS the best!

Happy baking!

  • 3 cups all-purpose flour
  • 2 teaspoons baking soda
  • 1/2 teaspoon salt
  • 1 cup of butter softened
  • 2 cups  white sugar
  • 2 teaspoons pure vanilla extract
  • 2 large eggs
  • 4 very ripe bananas
  • 1 cup of buttermilk
  • 1 cup of semi sweet chocolate chips
  • Chocolate Satin Glaze
  • 3/4 cup semisweet chocolate chips
  • 3 tablespoons butter
  • 1 tablespoon light corn syrup
  • 1/4 teaspoon vanilla extract


  • Kick the tires and light the fires to 350 degrees.
  • Cream your butter and sugar together in a mixer, or with a hand mixer.
  • Combine the dry ingredients together using a whisk.
  • Beat the eggs into the butter/sugar mix, one at a time and beating well after each.
  • Get your hand blender or whatever you can think of to puree the bananas. In a large container or bowl, puree the bananas until smooth. The smoother the banana’s the nicer your cake turns out!
  • Add in the buttermilk and puree again, until it’s a non-lumpy liquid.
  • Add your flour into the butter mixture and combine completely. .
  • After you completely mix in the dry, slowly pour in the liquid banana/buttermilk mixture.
  • Right when it’s almost mixed, add in your chocolate chips. Mix slowly until they are combined.
  • Pour into a greased and floured bundt pan.
  • Bake at 350 degrees, 40-50 minutes, until a knife inserted comes out clean and it’s a gorgeous brown.
  • Remove and cool for 5 minutes, then invert onto a baking rack to cool completely.
  • To make the glaze, combine the ingredients in a microwave safe glass measuring cup. Microwave 30 seconds at a time ,stirring after each, until the mixture is smooth.
  • Pour the glaze over the cake and let set.

    This recipe doesn’t tell you when to mix in the vanilla extract into the cake mixture!

    • Annie B says

      Exactly what I was gonna mention…what I did is mix in the vanilla with the wet ingredients (see step 4) after the eggs were mixed in as I have another recipe that indicates this.

  2. Karlynn says
