Preheat the oven to 425F. Line a muffin tin with silicone muffin liners or grease.
Mash bananas. Add in eggs, maple syrup, and almond milk. Mix until well combined.
Add in oats and let sit for 5-10 minutes. (I usually just put away the ingredients I've already used.)
Add the whole wheat pastry flour, cinnamon, baking powder, and baking soda. Mix until just combined.
Fold in blueberries. Divide batter among the muffin tin evenly. Place in oven and immediately turn down to 350F. Bake for 15-20 minutes or until an inserted toothpick comes out clean.
