Prep Your Oven and Pan
Preheat your oven to 350°F (175°C). Line a standard 12-cup muffin tin with paper liners or spray generously with non-stick cooking spray. Mash the Bananas
In a large mixing bowl, mash the bananas with a fork until smooth. A few small lumps are totally fine!Combine the Wet & Dry Ingredients
Whisk in the eggs and nut butter until completely combined. Then, fold in the rolled oats. Stir well until a uniform batter forms. Fill and Bake
Divide the batter evenly among 8 to 10 muffin cups (they will fill about 3/4 of the way). Bake for 15 to 18 minutes, or until a toothpick inserted into the center comes out clean and the tops spring back when lightly touched.Cool and Serve
Allow the muffins to cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely. Enjoy warm!
