Next, I peel the bananas and mash them in a large bowl until they become mostly smooth. I’ve learned that very ripe bananas work best here. The darker the bananas, the sweeter and more flavorful the brownies become. Once mashed, I add the peanut butter and cocoa powder.
Then I mix everything together until a thick brownie batter forms. If I want a sweeter dessert, I stir in a little maple syrup. Sometimes I also add chocolate chips because they create delicious pockets of melted chocolate throughout the brownies. The batter should be thick, smooth, and evenly combined.
Finally, I spread the batter into the prepared loaf pan and smooth the top. If I’m using chocolate chips, I sprinkle a few extra on top before baking. I bake the brownies for about 18–20 minutes, just until the center is set. After baking, I let them cool completely before slicing. The first time I rushed this step, and the brownies were too soft. Cooling allows them to firm up into the perfect fudgy texture.
Pro Tips for Best Results
I tested this recipe with bananas at different stages of ripeness, and very overripe bananas consistently produced the best flavor and texture. Don’t use firm yellow bananas if you can avoid it.
Another thing I learned is that natural peanut butter works beautifully, but it should be stirred well before measuring. Separated peanut butter can affect the consistency of the batter.
If you love extra chocolate flavor, adding chocolate chips is absolutely worth it. I’ve made the brownies both ways, and the chocolate chips make them feel even more indulgent.
Common Mistakes to Avoid
The biggest mistake I made the first time was under-mashing the bananas. Large banana chunks created an uneven texture throughout the brownies. A smoother mash produces better results. (See the next page below to continue…)
