Ingredients

For the Cookies:

1 2/3 cups all-purpose flour

2/3 cup unsweetened cocoa powder

1 1/2 teaspoons baking soda

1/2 teaspoon baking powder

1/2 teaspoon salt

1/2 cup unsalted butter, softened

1 cup granulated sugar

1 large egg

1 teaspoon vanilla extract

1 cup buttermilk

For the Filling:

1/2 cup unsalted butter, softened

1 1/2 cups powdered sugar

1 cup marshmallow fluff

1 teaspoon vanilla extract

Orange food coloring (optional)

Optional Decorations:

Halloween sprinkles (optional, for rolling edges)

Instructions

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

In a medium bowl, whisk together dry ingredients: flour, cocoa powder, baking soda, baking powder, and salt.

In a large bowl, cream butter and sugar until light and fluffy.

Add egg and vanilla, beat until fully incorporated.

Alternately add dry ingredients and buttermilk to the wet mixture, starting and ending with dry. Mix until just combined.

Drop tablespoon-sized dollops of batter onto baking sheets, spaced 2 inches apart.

Bake for 10–12 minutes, until tops are set and spring back to the touch. Let cool on the pan 5 minutes, then transfer to a wire rack.

Make the filling: Beat butter until smooth. Add powdered sugar and beat until fluffy. Mix in marshmallow fluff and vanilla. If desired, add food coloring.

Once cookies are cool, sandwich with filling and gently press together.

Roll in sprinkles, if using. Serve or store in an airtight container for up to 3 days.

Notes

Let cookies cool completely before filling to prevent melting.

No buttermilk? Substitute with 1 cup milk + 1 tbsp vinegar or lemon juice.

Switch up food coloring for different festive looks (purple, green, etc.).

These are great make-ahead treats and stay soft for up to 3 days at room temperature.
