Preheat oven to 350 degrees F and coat a 24-cup mini muffin pan with baking spray (I used a silicone one, and placed on a baking sheet)
Pulse your rolled oats in a blender until finely ground
Add baking powder, baking soda, cinnamon, and salt, then pulse to combine
One at a time, add your eggs, then banana, brown sugar, oil, and vanilla
Pulse between ingredients briefly, then puree until smooth
Mix in chocolate chips by hand and pour into the muffin cups, filling to the rim. They don’t rise very much
Bake until a toothpick inserted in the center comes out clean, about 15 to 17 minutes. As ovens vary, check yours to ensure they don’t overcook
Allow to cool in the pan on a rack until just able to lift out, then cool completely on a wire rack
Store in an airtight container at room temperature for 5 days (if they last!)
Notes
Although this recipe has not been lab tested, a single serving should be low-FODMAP based on the ingredients (using available FODMAP data at time of testing)
For bananas, one low-FODMAP serving of ripe banana is 35g. See more about bananas and FODMAPs in the header above, or in my TikTok videos!
Yield 24 muffins, 1-2 per serving
Try with walnuts or pecans instead of chocolate if you prefer
