Step 1: Prepare the Dry Ingredients

In a medium-sized bowl, whisk together the flour, cocoa powder, baking soda, and salt. Set aside.

Step 2: Mix the Wet Ingredients

In a large mixing bowl, beat the softened butter and sugar until light and fluffy. Add the egg and vanilla extract, and mix well.

Step 3: Add the Buttermilk and Food Coloring

Gradually add the buttermilk and red food coloring to the butter mixture, mixing until fully incorporated.

Step 4: Combine Dry and Wet Ingredients

Slowly add the dry ingredient mixture to the wet ingredients, stirring until just combined. Avoid over-mixing to keep the cookies soft and fluffy.

Step 5: Shape and Bake

Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper. Use a cookie scoop or spoon to drop equal portions of batter onto the sheet, spacing them 2 inches apart. Bake for 10-12 minutes or until the cookies spring back when lightly touched. Let them cool on a wire rack.

Step 6: Prepare the Cream Cheese Filling

In a bowl, beat together the cream cheese and butter until smooth. Gradually add powdered sugar and vanilla extract, mixing until fluffy.

Step 7: Assemble the Whoopie Pies

Once the cookies have cooled, spread or pipe the cream cheese filling onto the flat side of one cookie, then sandwich it with another cookie.

Step 8: Serve and Enjoy!

Enjoy your homemade Red Velvet Whoopie Pies with a glass of milk or your favorite hot beverage.
