Ingredients

3 cups all-purpose flour

1 teaspoon baking soda

1 teaspoon baking powder

1/2 teaspoon salt

1 cup unsalted butter, softened

1 1/2 cups granulated sugar

2 large eggs

1 tablespoon vanilla extract

1 cup buttermilk

Red gel food coloring

Blue gel food coloring

1 cup unsalted butter, softened (for filling)

4 cups powdered sugar

2 tablespoons heavy cream

1 tablespoon vanilla extract (for filling)

Pinch of salt

Instructions

  1. Preheat the oven to 350°F and line two baking sheets with parchment paper.
  2. In a medium bowl, whisk together the flour, baking soda, baking powder, and salt.
  3. In a large bowl, beat the softened butter and granulated sugar until light and fluffy. Add the eggs one at a time, mixing well after each addition, then mix in the vanilla extract.
  4. Gradually add the dry ingredients to the butter mixture, alternating with the buttermilk. Begin and end with the dry ingredients and mix until just combined.
  5. Divide the batter evenly into two bowls. Mix red gel food coloring into one bowl and blue gel food coloring into the other until vibrant.
  6. Using a cookie scoop, portion the batter onto the prepared baking sheets, leaving space between each cookie.
  7. Bake for 9 to 11 minutes until the tops are set. Cool completely on a wire rack.
  8. To make the filling, beat the softened butter until smooth. Gradually add the powdered sugar, then mix in the heavy cream, vanilla extract, and salt until fluffy.
  9. Pipe or spread the filling onto the flat side of one cookie and top with another cookie to form a sandwich.
  10. Serve immediately or refrigerate until ready to enjoy.

Notes

Add patriotic sprinkles around the filling edges for extra decoration.

Marshmallow fluff can be added to the filling for a classic whoopie pie texture.

Store in an airtight container in the refrigerator for up to 4 days.

Place parchment paper between layers to prevent sticking.

Let sit at room temperature for 15 minutes before serving for the best texture.

Freeze for up to 2 months and thaw overnight in the refrigerator.

Gel food coloring works best because it keeps the batter thick while creating vibrant colors.
