Marshmallow Monstrosity Cups

This recipe was born out of a gooey brownie recipe that is a favorite of mine, and all it takes is the addition of marshmallows. I learned two very important lessons when I baked this dessert. First, place a piece of aluminum foil under the pan to catch the marshmallows that explode out of their respective cups. Second, sometimes delicious desserts do not look very pretty.
  • 16 tablespoon unsalted butter
  • 6 jumbo marshmallows, cut in half horizontally
  • 1/2 cup sugar
  • 1 1/4 cup chocolate chips
  • 2 teaspoon vanilla extract
  • 1 1/4 cup all-purpose flour
  • 2 eggs, beaten
  • 12 peanut butter creme cookies
  • 1/2 teaspoon salt
  • 3/4 cup light brown sugar
  1. Place a piece of aluminum foil on middle rack of oven. Preheat the oven to 350 degrees. Set aside a 12-cup muffin pan.
  2. Place the butter, brown sugar, and sugar into a large microwaveable bowl. Microwave until the mixture is completely melted and bubbly. Be sure to use oven mitts when removing the bowl from the microwave as it will be very hot.
  3. Whisk the mixture to blend the ingredients together. Whisk in the vanilla, then the flour and salt.
  4. Continuously whisk the mixture while adding the eggs, one at a time, to prevent cooking the eggs.
  5. Lastly, use a wooden spoon to mix in the chocolate chips. Most will melt, but you will have some that still hold their shape.
  6. Spray the pan with non-stick cooking spray. Use a large cookie dough scoop to transfer batter to pans. For each cup, scoop just under half the scoop of batter and place a peanut butter creme cookie over this. Place marshmallow half on top of cookie. Top it with the remaining half of batter in the scoop. This will drip down sides of each marshmallow as well, covering them completely.
  7. Bake on the aluminum foil for 18 minutes. The marshmallows will look like they have exploded, which is pretty accurate.
  8. Remove and cool completely in the pan. Use a small metal spatula to go around the edges of the Marshmallow Monstrosity Cups and lift out of pan. Some will lift out very easily and some will have to be helped out of the pan.
