# What you need:
→ Chocolate Cookies
01 - 2 cups all-purpose flour
02 - 1/2 cup unsweetened cocoa powder
03 - 1 teaspoon baking soda
04 - 1/2 teaspoon salt
05 - 1 cup granulated sugar
06 - 1/2 cup unsalted butter, softened
07 - 1 large egg
08 - 1 cup buttermilk
09 - 1 teaspoon vanilla extract
→ Marshmallow Filling
10 - 1/2 cup unsalted butter, softened
11 - 1 1/4 cups powdered sugar
12 - 1 jar marshmallow creme (7 ounces)
13 - 1 teaspoon vanilla extract
14 - Pinch of salt
# Directions:
01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - Whisk together flour, cocoa powder, baking soda, and salt in a medium bowl until evenly incorporated.
03 - Beat softened butter and granulated sugar in a large bowl until light and fluffy, approximately 2 minutes.
04 - Add egg and beat until fully combined. Mix in buttermilk and vanilla extract. The batter may appear curdled, which is expected.
05 - Gradually add dry ingredients to wet mixture, mixing just until combined. Do not overmix.
06 - Drop rounded tablespoons of batter onto prepared baking sheets, leaving 2 inches of space between each.
07 - Bake for 10 to 12 minutes until tops spring back when gently pressed. Cool completely on wire rack.
08 - Beat butter until creamy. Add powdered sugar and beat until smooth. Incorporate marshmallow creme, vanilla, and salt until fluffy and fully combined.
09 - Spread or pipe filling onto flat side of half the cookies. Top with remaining cookies, flat side down, to form sandwiches.
