# How-To Steps:
01 - Preheat oven to 350°F (175°C) and line two baking sheets with parchment paper.
02 - In a medium mixing bowl, whisk together flour, cocoa powder, baking soda, and salt.
03 - In a large bowl, beat unsalted butter and granulated sugar until light and fluffy using an electric mixer. Incorporate the egg until fully blended.
04 - Mix buttermilk and vanilla extract into the butter mixture. Gradually add dry ingredients, mixing until a smooth batter forms.
05 - Using a spoon or cookie scoop, drop 24 equal portions of batter onto prepared sheets, keeping a 2-inch gap between rounds.
06 - Bake in the preheated oven for 10 to 12 minutes, or until cakes are set and spring back when lightly touched. Cool completely on a cooling rack.
07 - Beat softened unsalted butter until creamy. Add powdered sugar, marshmallow creme, vanilla, and a pinch of salt. Continue beating until filling is light and fluffy.
08 - Divide frosting into three separate bowls. Leave one batch white, tint one batch red, and tint the remaining batch blue using food coloring.
09 - Pipe or spoon filling onto the flat side of half the cakes. Top with remaining cakes to form sandwich pies.
10 - Roll the edges of assembled pies in patriotic sprinkles or pipe colored frosting on top as desired for garnish.
# Expert Tips:
01 -
- The marshmallow filling makes these treats disappear in a blink when set out at any party, trust me.
- They're fun to decorate and surprisingly forgiving—messy frosting just means more sprinkles.
02 -
- If you skip cooling the cakes completely, the filling melts and oozes everywhere—lesson burned in my memory.
- Leaving the whoopie pies in the fridge for a bit firms them up and makes the sandwich bite so much tidier.
03 -
- Sifting powdered sugar and cocoa powder before mixing gives you extra smooth batter and filling.
- Chilling the filled pies for thirty minutes keeps the frosting set and makes every bite cleaner and more satisfying.
