Deliciously moist and fluffy chocolate muffins that are loaded with peanut butter and banana flavour, and stuffed full of chocolate chips. Perfect with a hot cup of tea or coffee!
Spoon the mixture into the prepared pan. Spoon a small dollop of runny peanut butter on the tops, and use a knife or toothpick to create swirls. Bake for 15 - 20 minutes.
