  • Method: Baked
  • Cuisine: American

Ingredients

For the chocolate cakes:

  • 2 cups all-purpose flour
  • 1/2 cup unsweetened cocoa powder
  • 1 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1 cup granulated sugar
  • 1/2 cup vegetable oil
  • 1 large egg
  • 1 cup buttermilk
  • 1 tsp vanilla extract
  • 1/2 cup hot water

For the filling:

  • 1/2 cup unsalted butter, softened
  • 1 1/2 cups powdered sugar
  • 1 jar (7 oz) marshmallow creme or fluff
  • 1 tsp vanilla extract

Instructions

  1. Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
  2. In a large bowl, whisk together flour, cocoa powder, baking soda, and salt.
  3. In another bowl, beat sugar and oil until combined. Mix in egg, buttermilk, and vanilla.
  4. Gradually add dry ingredients to wet mixture, stirring just until combined. Stir in hot water until batter is smooth.
  5. Drop batter by spoonfuls (about 2 tbsp each) onto prepared sheets, spacing well apart.
  6. Bake 10–12 minutes, until tops are puffed and set. Cool completely on wire racks.
  7. For filling: Beat butter until light and fluffy. Gradually add powdered sugar, then beat in marshmallow creme and vanilla until smooth.
  8. Spread or pipe filling onto flat side of one cooled cake, then sandwich with another cake.

Notes

  • Chill batter for 10–15 minutes before scooping to prevent spreading.
  • For holiday variation, add peppermint extract or crushed candy canes to filling.
  • Make mini whoopie pies by using smaller scoops and reducing bake time by 2–3 minutes.
