Preheat the oven to 375 degrees F. Line a muffin tin with 10 muffin liners (we’re only making 10 muffins). Spray the inside of the muffin liners with nonstick cooking spray so the muffins do not stick to the liners.
Add the eggs, bananas, maple syrup/honey, dairy free milk, spinach and vanilla extract to a large, high powered blender and blend on high for 1 minute or until completely smooth. Set aside.
In a large bowl whisk together the almond flour, oat flour, flaxseed meal, cinnamon, baking powder, baking soda and salt until well combined. Pour the blended wet ingredients over the dry ingredients and mix with a wooden spoon until well combined. Feel free to stir in hemp hearts, if using. Divide the batter between the muffin liners. Bake for 20-25 minutes or until a toothpick comes out clean or with just a few crumbs attached.
