Whether you overbought at the farm stand or your fruit is ripening quicker than you can eat it, this blueberry banana cake is the perfect way to use up the produce and enjoy something sweet. What is great about this recipe is that there are more bananas and blueberries in the batter than flour and sugar, which makes it not only extra fruity and delicious, but also a healthy breakfast, dessert, or snack. 

This cake was made in a cathedral Bundt cake pan, but you can use any Bundt, cake, or loaf pan.

Tips

This recipe is somewhat simple, but there are a few tips you should keep in mind to ensure your banana blueberry cake is a success:

  • First, it is important that the butter and eggs be at room temperature so they both mix into the batter uniformly.
  • You also want to make sure that the bananas are nice and ripe; the goal is to have them blend into the batter versus remain in chunks. Bananas with almost black skins are ideal.
  • To achieve the creamiest texture, mash the ripe bananas with a mixer until they are a thick puree. You can use frozen bananas as well, just remember to thaw first.
  • When it comes to the blueberries, you need completely dry them before adding to the batter. Introducing water to the batter will result in a soggy cake.
  • This recipe can be baked in a Bundt pan, loaf pan, or muffin tins. Just be sure to adjust the cooking times (muffins will take about half the time).

Recipe Variations

Whether you add or sub out ingredients in this cake, there are a few twists on this recipe that are sure to please:

  • Add walnuts to the batter—or sprinkled on top—brings a nice crunch to the cake.
  • Add chocolate chips or shaved chocolate on top for decoration and flavor.
  • Layer a streusel topping before baking, which will create a sweet, crispy outer crust.
