Preheat the oven to 350°F (175°C) and line a muffin tin with 8 muffin liners. I recommend silicone liners as these muffins stick a bit to paper ones. If you have to use paper, then waiting a few hours after baking helps make removing the liners easier.
Add the mashed bananas, eggs, vanilla and coconut sugar to a large mixing bowl, and stir until combined.
1 cup (230 grams) mashed bananas, 2 large eggs, 2 teaspoons vanilla extract, 2 tablespoons (22 grams) coconut sugar
In a medium bowl, mix together the almond flour, cinnamon, salt and baking soda. Add the dry mix to the wet and stir just until combined.
1 1/3 cups (133 grams) almond flour, 1 tablespoon ground cinnamon, 1/4 teaspoon salt, 3/4 teaspoon baking soda
Spoon the batter into the muffin liners, filling them 2/3 full.
Bake for 17 minutes or until a toothpick inserted in the center comes out clean.
Let the muffins cool for 5 minutes in the pan and then turn out onto a wire rack to cool completely. These muffins are best after they've rested for a few hours.
Store in an airtight container for 2-3 days at room temperature. These are very moist so I don't recommend keeping them at room temp so long. You can also refrigerate for 5 days or freeze for 2 months.
