Method

For the Cake

  1. 1

    Prepare the Oven

    Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

  2. 2

    Mix Dry Ingredients

    In a bowl, whisk together flour, cocoa powder, baking soda, and salt. Set aside.

  3. 3

    Cream Butter and Sugars

    In a large bowl, cream the softened butter, granulated sugar, and brown sugar until light and fluffy.

  4. 4

    Add Eggs and Vanilla

    Beat in the eggs one at a time, then mix in the vanilla extract.

  5. 5

    Combine Mixture

    Gradually add the dry ingredients to the butter mixture, alternating with the buttermilk, starting and ending with the dry ingredients.

  6. 6

    Scoop and Bake

    Using a cookie scoop, drop spoonfuls of batter onto the prepared baking sheets, spacing them about 2 inches apart. Bake for 10-12 minutes, until the edges are set.

  7. 7

    Cool the Cakes

    Remove from the oven and let them cool on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely.

    Make the Filling

    In a medium bowl, beat together the marshmallow fluff, softened butter, powdered sugar, and vanilla extract until smooth and well combined.

Assembly

    Take one cake round and spread a generous amount of the filling on the flat side, then top with another cake round, flat side down. Repeat with remaining cakes.
