Step 1

Preheat oven to 350°F (175°C). Spray a muffin pan generously with oil, or use a silicone muffin pan for easy removal.

Step 2

In a mixing bowl or stand mixer, combine all ingredients: mashed bananas, peanut butter, eggs, vanilla, maple syrup, cocoa powder, baking soda, and chocolate chips.

Step 3

Mix with hand mixer or standing mixer until smooth and fully combined.

Step 4

Spoon batter into prepared muffin pan, filling each cup about 3/4 full.

Step 5

Bake for 15 minutes, or until muffins are set and a toothpick comes out clean.

Step 6

Let cool completely in the muffin pan—this helps them set up fully. (They may deflate slightly as they cool; this is totally normal!)
