To make these muffins, start by preheating your oven to 325 F.
Next, prepare the muffin tin. Line a muffin tin with liners or grease the inside of the muffin cavities with butter or oil.
Prepare the dry ingredients. In a medium bowl, mix together the gluten-free flour, almond flour, coconut sugar, cinnamon, baking soda, and sea salt until just combined. Set them aside while you prepare the wet ingredients.
Add all of the wet ingredients (the eggs, bananas, non-dairy milk, maple syrup, and vanilla extract) to a blender. Blend until the ingredients are fully smooth.
Once the wet ingredients have come together, slowly pour them into the bowl with the dry ingredients, mixing until a thick batter forms. Be careful not to over-mix here, as the batter can turn out tough!
Prepare the blueberries by adding them to a small bowl, alongside the flour, and mixing them gently until they're fully coated in the flour.
Then, fold the blueberries into the muffin batter.
Divide the muffin batter evenly amongst all of the cavities and transfer the tray into the oven.
The bake time will be dependent on the size of muffin tin that you use. For smaller or standard sized muffins, bake for 20-22 minutes, or until a toothpick comes out clean. For larger muffins, bake for 28-30 minutes, or until a toothpick comes out clean.
Once the muffins are done, remove them from the oven. Allow them to cool completely, then enjoy!
