# How To Make It:

01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together all-purpose flour, unsweetened cocoa powder, baking soda, and salt until evenly combined.
03 - In a large bowl, beat unsalted butter and granulated sugar with an electric mixer until light and fluffy. Add the egg and mix thoroughly.
04 - Add buttermilk and vanilla extract to the butter mixture. Gradually incorporate the dry mixture, blending until batter is smooth.
05 - Spoon or scoop 24 equal portions of batter onto prepared trays, spacing 2 inches apart. Bake for 10 to 12 minutes, or until the cakes are set and spring back when touched. Let cool completely on a wire rack.
06 - Beat softened butter until creamy. Add powdered sugar, marshmallow creme, vanilla extract, and a pinch of salt. Beat until the mixture is light and fluffy.
07 - Divide the filling evenly into three bowls. Leave one batch plain, tint one batch red, and tint the remaining batch blue with food coloring.
08 - Pipe or spread an even layer of filling on the flat side of half of the cakes. Top with the remaining cakes to create sandwiches.
09 - Roll the edges of each whoopie pie in patriotic sprinkles, or pipe additional colored frosting on top if desired.

# Helpful Hints:

01 -
  • The secret is in the marshmallow filling—it&aposs light, fluffy, and never too sweet.
  • I love how the food coloring transforms every batch into an instant party centerpiece.
02 -
  • If you try to fill the cookies before they're fully cool, the frosting slides right off in sticky defeat.
  • Using parchment paper is non-negotiable—nothing sticks, and your cakes lift off like a dream.
03 -
  • Bake only one sheet at a time if you want perfectly even cakes—trust me, it&aposs worth it.
  • A little extra marshmallow creme transforms the filling into pure cloud-like magic.
