When life hands me overripe bananas, I hand life back banana desserts and smoothies. I either freeze them to make ice-free smoothies for light breakfasts (my fav being peanut butter/vanilla/banana), or make them into my Dad’s Favorite Banana Bread.

For this round of overripe bananas, however- I wanted to try something a bit different. Armed with an arsenal of gluten-free baking ingredients I picked up from H Mart, I set my sights on making a gluten-free dessert, with a slight twist.

You’ll whisk the dry ingredients, then stir in the peanut butter, bananas, vegetable oil, and eggs- the fold the chocolate chips in and throw the whole thing in the oven for 25-30 minutes. Let that bad boy cool in the pan or on a cooling rack, and dive in!

Not a fan of peanut butter or don’t have it on hand? Trade in your favorite nut butter. I used a standard/sweetened creamy peanut butter for this recipe.
