Ingredients

  • 1.5 cup all-purpose flour sifted
  • 0.75 cup unsweetened cocoa powder Dutch-processed for deeper flavor
  • 1.5 cup granulated sugar
  • 1.5 tsp baking powder
  • 1 tsp baking soda
  • 2 large eggs room temperature
  • 0.75 cup whole milk
  • 0.33 cup vegetable oil
  • 0.75 cup boiling water to bloom the cocoa
  • 7 oz marshmallow fluff one standard jar
  • 0.5 cup semi-sweet chocolate chips for the ganache
  • 0.25 cup heavy cream

Notes

Store leftovers in an airtight container at room temperature for up to 2 days. For a 'S'mores' twist, sprinkle crushed graham crackers over the chocolate drizzle. Do not refrigerate as it can cause the marshmallow fluff to become sticky and the cake to dry out.
