These muffins are best with very ripe bananas (they should have a lot of brown spots, which indicate sweetness). Then, simply stir everything together in one bowl and bake up a batch of delicious Banana Chocolate Chip Muffins to share with the kids.
Preheat the oven to 400 degrees F and grease a standard muffin tin. Set aside.
Mash the banana very smooth with a potato masher or fork.
Add the flour, sugar, flaxseed (if using), cinnamon, baking powder, baking soda, and salt to a medium bowl. Stir together.
Add the banana, eggs, milk, peanut butter, and vanilla and stir well.
Add the chocolate chips.
Spoon batter into prepared muffin tin, using about 1/4 cup batter for each. Top with additional chocolate chips if desired.
Bake for 16-20 minutes or until a cake tester inserted into the center comes out cleanly and the edges are golden brown.
Let cool for about 5 minutes in the pan, then run a paring knife around the edges to help remove the muffins. Cool on a wire rack.
