Preheat the oven to 350 degrees F. Spray a standard-size muffin pan with a light coating of non-stick cooking spray.
Using a fork or immersion blender, mash the banana into a paste in a large mixing bowl.
1 medium ripe banana
Add the almond butter, milk, sugar and vinegar and mix until completely smooth and creamy.
1/4 cup almond butter, 1/2 cup coconut sugar, 2/3 cup unsweetened non-dairy milk, 1 tbsp apple cider vinegar or white vinegar
Add the buckwheat flour, baking powder and salt. While they're sitting on top of the wet ingredients, gently mix the dry ingredients together to incorporate the baking powder and salt, then fold the dry ingredients into the wet until all the flour is wetted. Do not overmix the batter. Fold it just enough to wet all the flour, then stop mixing.
2 cups light buckwheat flour, 2 tsp baking powder, 1/4 tsp salt
Add the chocolate chips and grated carrot and gently fold them in a few times to mix.
1/2 cup dairy-free or dark chocolate chips, 1 cup finely grated carrot
Evenly divide the batter between 12 muffin cups. Bake for 20-22 minutes until browned and firm on top.
Remove from the oven and let cool in the pan for 4-5 minutes then gently pop them out using a knife and place them on a cooling rack to finish cooling.
