Prep time: 25 mins

Total time: 1 hour 15 mins
  • 1 pound (454 grams) marshmallow fluff
  • 2 cups (396 grams) chocolate chips, divided
  • 2 cups (284 grams) all purpose flour
  • ½ cup (50 grams) cocoa powder, plus additional for dusting the pan
  • ½ teaspoon (3 grams) baking soda
  • ¼ teaspoon (2 grams) salt
  • 14 tablespoons unsalted butter, softened
  • 1¾ cups (380 grams) sugar
  • 3 eggs
  • ¾ cup (184 grams) sour cream
  • 1½ teaspoons (5 grams) vanilla extract
  1. Preheat the oven to 325°. Butter and dust a 10 cup bundt pan with unsweetened cocoa powder and set aside.
  2. Stir the marshmallow fluff directly in the container to release air. Stir in 1 cup (198 grams) chocolate chips. Place a gallon size plastic freezer bag into a large glass, folding the seal backwards so that the fluff does not get stuck on the seal. Transfer the fluff/chocolate chip mixture to the bag. Release the air and seal the bag. Set aside.
  3. Whisk together the flour, cocoa powder, baking soda and salt. Set aside.
  4. Place the butter and sugar into a large mixing bowl. Cream the mixture until light and fluffy. Add the eggs, one at a time.
  5. Blend in one-half of the dry ingredients followed by the sour cream and vanilla. Blend in the remaining dry ingredients.
  6. Stir in the remaining 1 cup (198 grams) chocolate chips.
  7. Transfer a third of the batter to the prepared pan. Use the back of a spoon to make a well in the center of the batter, all the way around.
  8. Cut off a piece of one of the bottom corners of the fluff/chocolate chip bag, roughly ¾" wide. Squeeze half of the fluff/chocolate chip mixture into the well. Spoon the remaining batter over the top of the fluff.
  9. Bake at 325° for 50 minutes.
  10. Remove from the oven and cool completely in the pan.
  11. Once the cake has cooled, invert the cake directly onto the serving plate. Squeeze the remaining marshmallow/chocolate chip mixture over the top of the cake.
Additional time is needed for the cake to cool.
