Preheat the oven to 350 degrees F. Line a 12 cup muffin tin with muffin liners. I prefer to use parchment paper liners as they easily peel away from the muffins!
In a large bowl, whisk together the white whole wheat flour, coconut sugar, cacao powder, instant espresso (optional) baking powder, baking soda, and salt.
Place ripe bananas in a food processor with the blade attachment. Pulse until bananas are smooth and pureed.
Make a well in the center of the dry ingredients. Pour in the pureed banana, almond milk, and vanilla extract. Fold together until just combined.
Add the chocolate chips, and gently fold into the batter.
Using an ice cream scoop, or measuring cup, fill the muffin cups ⅔ of the way full. You should have enough batter for 12-14 muffins depending on how much batter you add to each cup. Sprinkle a few mini chocolate chips on top of each muffin.
Place in preheated oven for 20 minutes, or until toothpick inserted in the center comes out clean. Allow to cool in the muffin tin for 5 minutes, then transfer to a wire rack to cool completely. Enjoy!
