Why You’ll Love Red White and Blue Cookie Sandwiches Whoopie Pies Recipe

I love how soft and tender these whoopie pies stay even after chilling. The red and blue colors give them a festive patriotic look that works beautifully for 4th of July parties, Memorial Day gatherings, and summer cookouts. I also like that the filling is smooth, fluffy, and easy to spread or pipe between the cookies.

I find this recipe easy to prepare because the batter comes together quickly and the cookies bake in just a few minutes. The sandwiches also store well, making them convenient for preparing ahead before parties or events.

Ingredients

(Note: All ingredient amounts are listed in the recipe card below.)

FOR THE WHOOPIE PIE COOKIES

3 cups all-purpose flour
1 teaspoon baking soda
1 teaspoon baking powder
½ teaspoon salt
1 cup unsalted butter, softened
1 ½ cups granulated sugar
2 large eggs
1 tablespoon vanilla extract
1 cup buttermilk
Red gel food coloring
Blue gel food coloring

FOR THE VANILLA FILLING

1 cup unsalted butter, softened
4 cups powdered sugar
2 tablespoons heavy cream
1 tablespoon vanilla extract
Pinch of salt

Directions

1. I preheat the oven to 350°F and line two baking sheets with parchment paper to keep the cookies from sticking.
2. In a medium bowl, I whisk together the flour, baking soda, baking powder, and salt until evenly combined.
3. In a large bowl, I beat the softened butter and granulated sugar together until light and fluffy. I add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.
4. I gradually add the dry ingredients to the butter mixture, alternating with the buttermilk. I begin and end with the dry ingredients and mix only until combined.
5. I divide the batter evenly into two bowls. I stir red gel food coloring into one bowl and blue gel food coloring into the other until the colors are vibrant and smooth.
6. Using a cookie scoop, I portion the batter onto the prepared baking sheets, leaving room between each cookie for spreading.
7. I bake the cookies for 9 to 11 minutes until the tops are set and the centers no longer look wet. I let them cool completely on a wire rack.
8. For the filling, I beat the softened butter until smooth. I gradually mix in the powdered sugar, then add the heavy cream, vanilla extract, and salt. I continue beating until the filling becomes light and fluffy.
9. I pipe or spread the filling onto the flat side of one cooled cookie and top it with another cookie to create a sandwich.
10. I serve the whoopie pies immediately or refrigerate them until ready to enjoy.

Cook Time: 10 minutes
Additional Time: 20 minutes
Total Time: 55 minutes

Variations

I sometimes add patriotic sprinkles around the edges of the filling for extra color and texture. For a chocolate version, I mix a little cocoa powder into the batter to create a richer flavor. I also like using marshmallow fluff in the filling for a more classic whoopie pie texture.

For a brighter flavor, I occasionally add a small amount of almond extract or lemon extract to the filling. Mini versions also work wonderfully for dessert trays and party platters.

Storage/Reheating

I store the assembled whoopie pies in an airtight container in the refrigerator for up to 4 days. I like placing parchment paper between layers to keep them from sticking together.

Before serving, I let the whoopie pies sit at room temperature for about 15 minutes so the filling softens slightly. These cookies do not need reheating, but I sometimes enjoy them slightly chilled during hot summer weather.

FAQs

How do I keep the whoopie pies soft?

I make sure not to overbake the cookies. Removing them once the tops are set helps maintain a soft texture.

Yes, I often bake the cookies one day ahead and assemble them before serving.

Can I freeze whoopie pies?

I freeze them in an airtight container for up to 2 months and thaw them in the refrigerator overnight.

Why should I use gel food coloring?

I prefer gel coloring because it creates bright colors without thinning the batter.

Can I use store-bought frosting?

Yes, but I think homemade filling gives the best flavor and texture.

How do I make evenly sized cookies?

I use a cookie scoop so each cookie bakes to a similar size for easy sandwiching.

Yes, although the colors may appear softer and less vibrant.

What can I use instead of buttermilk?

I sometimes mix regular milk with a little lemon juice or vinegar as a substitute.
