Start mixing the first set of ingredients either the night before and bake the next morning (this is what I usually do) or start 6 to 8 before you plan on baking the muffins. Oftentimes, I will mix the batter right before I go to bed, around 10. Then, mix the rest of the ingredients around 7 am and bake.
Combine 2 cups of flour, 1/2 cup of honey, 1/2 stick of melted butter, 1 1/2 tsp of vanilla, 3 to 4 very ripe bananas, and 1 cup of active sourdough starter.
Cover the muffin batter while fermenting and leave it on the counter.
The next morning or 6 to 8 hours later, preheat the oven to 350F, then add the rest of the ingredients. Add and mix 2 eggs, 1/2 cup of peanut butter, 1/2 tsp of salt , 1 tsp baking powder, 1/2 baking soda, and chocolate chips.
Using a muffin tin and paper muffin baking cups, fill each muffin cup almost to the top.
Bake for 15 to 20 minutes or until a toothpick comes out clean.
After baking, remove the muffins from the tin and place on a cooling rack.
This recipe yields 12 to 14 muffins depending on the size of the muffin.
