Preheat the oven to 350 F
Pulse 1 cup of the rolled oats in a food processor until it resembles flour
In a large bowl, combine the 1 cup pulsed rolled oats, remaining 2 cups rolled oats, baking powder, cinnamon, and salt
In a separate medium bowl, whisk mashed bananas, eggs, almond milk, maple syrup and coconut oil
Pour the wet ingredients into the bowl of dry ingredients and mix with a rubber spatula until it comes together (the mixture may look wet, but the oats will absorb the moisture)
Scoop the mixture into the mini muffin pan, filling each cavity to the top
For toddlers and kids, add a few mini chocolate chips to the top of each cup before baking
Bake for 15-17 minutes until a toothpick inserted into the center of a mini oat muffin comes out clean
Let cool in the pan for a few minutes and then turn out onto a cooling rack. Best served warm, but can be stored in an airtight container in the fridge for about a week
