Do you ever stand there and stare at the pile of overripe bananas on your counter, wondering how many more times you can make banana chocolate chip bread?
Perhaps you want to make banana chocolate chip cake but need something a little more impressive for someone’s birthday?
One thing I’ve learned over the years from making my chocolate Bundt cake is that if you want a cake to look fancy without taking too much effort, put it in a Bundt pan.
And that’s how this Banana Bundt Cake was born!
It’s a banana bread bundt cake with a hidden chocolate cream cheese filling then drizzled with a chocolate ganache glaze on top.
This banana bundt cake recipe stays incredibly moist even after a few days thanks to the sour cream and overripe bananas.
And because this is a small batch baking blog, I also tested it in a 3-cup 6 inch Bundt cake as seen with my small Bundt cake recipe.
That way you can decide if you want a small or large chocolate banana cake!

What is a bundt cake?
A bundt cake gets its name from the type of pan used called a bundt pan. Traditionally it’s a ring-shaped pan with fluted sides, but there are some pans with more intricate patterns.
There are several sizes of Bundt pans – regular-sized pans that hold 10-12 cups batter, small 6 inch pans that hold 3 cups batter, and mini pans that are served individually.
This banana bundt cake recipe has been tested for both a regular-sized and small Bundt cake pans.

Why did my bundt cake stick to the pan?
The biggest challenge with making a homemade bundt cake is it has a tendency to stick to the pan. Here are some ways to prevent that when inverting:
- Use a pan that doesn’t have any scratches or damages in the nonstick coating. The older the pan, the more likely it’ll stick.
- Thoroughly grease the pan with cooking spray or brush with melted butter and coat with flour.
- Invert the pan while still warm but not TOO warm. Let it sit for about 15-20 minutes so it can set then flip onto a wire rack. If you let it cool completely, the cake is more likely to stick (especially if it has chocolate chips then the melted part may harden onto the pan).

- 2 large eggs, room temperature
- 1 + 1/4 cup mashed banana (roughly 3 medium ripe bananas)
- 1 cup full-fat sour cream, room temperature

Instructions
- Preheat oven to 350F. Lightly grease and flour a 12-cup bundt cake pan (*for 3-cup Bundt pan, see notes for measurements).
- In a large bowl, sift the flour then stir in the baking soda, cinnamon, and salt.
- In another large mixing bowl on medium speed (with the paddle attachment if using a stand mixer), beat together the butter and sugar until light and creamy, about 1-2 minutes.
- Scrape down the bowl then beat 2 eggs, one at a time. Beat in the banana, sour cream, and vanilla.
