Is this breakfast or dessert!? These soft, moist S'mores muffins are a treat and loaded with graham cracker crumbs, milk chocolate and marshmallow cream. The perfect way to start the day!
Preheat oven to 375°. Place 12 muffin liners into a muffin tin OR coat the muffin tin cups with nonstick cooking spray.
In the base of your stand mixer, cream together the butter and sugars until pale, light and fluffy. Beat in the eggs, one at a time. Add the sour cream and continue mixing until combined.
In a separate bowl, whisk together the dry ingredients. Add to the creamed mixture, alternating with the milk until all is incorporated. Fold in the chocolate chips.
Fill each cup 1/4 with batter. Spoon 1 tbsp of marshmallow fluff into each muffin cup and top with the remain batter, about 2/3 full in each cup. Place another 1/2 tbsp of marshmallow fluff on the top.
Bake 18-20 minutes, until a toothpick comes out clean. Cool for 5-10 minutes in pan and then place on a wire rack. Serve warm.
Notes
Note: You may fold in 1 cup mini marshmallows into the batter in place of the marshmallow fluff, if you prefer. You may also omit the top dollop of marshmallow fluff.
