Mash bananas with a fork in a large mixing bowl. You should make sure you have close to two cups. Add in eggs, maple syrup, and almond milk. Whisk with an electric hand mixer until combined.
2 cups mashed bananas, 3 large eggs, ½ cup maple syrup , ½ cup almond milk
Combine oats, almond flour, cinnamon, and baking powder in another medium bowl. Add dry ingredients to the wet, and mix until combined.
1 ½ cups rolled oats, 1 cup almond flour , 1 ½ teaspoons baking powder, 1 teaspoon cinnamon
Preheat the oven to 375F and prep the muffin pan by greasing or lining it with muffin cups while you wait for the oven to preheat, around 5-10 minutes, so the oats can soak. Divide batter among the 12 muffin cup holes. Bake for 10 minutes, rotate the pan 180 degrees, and bake for another 10 minutes or until the muffins are set and an inserted toothpick comes out clean.
Allow muffins to cool for five minutes in the pan, then remove and cool on a cooling rack. If you don't use a muffin liner, you may need to run a knife around the edge of each muffin to get them out.
