With the delicious flavor combination of banana and chocolate, these muffins are both delicious and nutritious. Be sure to use very ripe bananas since they taste the sweetest. Warm the muffins slightly after storing in the fridge if desired.
Preheat oven to 375 degrees F and grease a mini muffin tin with nonstick spray.
Mash the banana very smooth and measure out 1 cup.
Add the banana to a medium bowl with the rest of the wet ingredients. Whisk to combine well.
Add the remaining ingredients and whisk to combine. (I add the cocoa powder through a small sieve to remove any lumps.)
Add batter to the prepared muffin pan, using about 2 tablespoons batter in each.
Bake for 10-12 minutes or until a cake tester inserted into the center comes out cleanly. Use a paring knife to remove from the pan and cool on a wire rack.
(To make as standard size muffins, bake for 14-16 minutes.)
Notes
Store in the fridge for up to 5 days in an airtight container or in a zip-top freezer bag for up to 3 months.
Gluten-free: Use cup-for-cup gluten-free flour.
Dairy-free: Use melted coconut oil for the butter.
Egg-free: Omit the eggs. Increase the baking soda to 1 teaspoon and add 1/4 cup milk.
Blend the wet ingredients in a blender and add a handful of spinach if desired.
Some mini muffin tins have a tendency to stick, so be sure to grease them well. (I like this mini muffin tin from Wilton.)
Very ripe bananas with brown spots have the most natural sweetness and will make these muffins taste best.
