1. Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners or lightly grease it.
2. Mash the bananas in a large bowl until smooth.
3. Add wet ingredients: Stir in honey (or maple syrup), applesauce, almond milk, egg, and vanilla extract.
4. Mix dry ingredients: In a separate bowl, whisk together gluten-free flour, baking soda, baking powder, cinnamon, and salt.
5. Combine: Gradually add the dry ingredients to the wet mixture, stirring until just combined.
6. If desired, fold in chopped walnuts or chocolate chips for extra flavor and texture.
7. Spoon the batter evenly into the muffin tin, filling each cup about 3/4 full.
8. Bake in the preheated oven for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
9. Allow the muffins to cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.

Enjoy your healthy, delicious banana muffins as a snack or breakfast!
