Chocolate Peanut Butter Swirl Muffins

We all really liked these and I will definitely make them again. They get a 7.5 and came from ourbalancedbowl.com. 3 medium ripe bananas 1/4 cup pure maple syrup 1 large egg 1/2 cup vegetable oil I used olive oil 1 cup all purpose flour 1/4 cup cocoa powder 1 tsp baking powder 1 tsp baking soda 1/4 tsp salt 1/4 cup peanut butter I just added 1/2 TBS to the top of each muffin before baking 1/2 cup semi-sweet chocolate chips https://ourbalancedbowl.com/chocolate-peanut-butter-swirl-muffins/
