Ingredients
Method
Preparation
- Preheat your oven to 350°F and line two baking sheets with parchment paper.
- In a medium bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and salt.
- In a large bowl, beat the softened butter and brown sugar on medium speed for 2-3 minutes until light and fluffy. Add the egg and vanilla extract, mixing until well combined.
- In a small bowl, whisk together the orange food coloring gel and vinegar into the buttermilk.
- With the mixer on low speed, gradually add the flour mixture to the butter mixture in three additions, alternating with the orange buttermilk.
Baking
- Transfer the batter to a piping bag and pipe 28 mounds about 1 1/2 inches wide onto the prepared baking sheets, spacing them 2 inches apart.
- Bake for 10-12 minutes. The cakes should spring back lightly when touched. Allow cooling on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
Filling and Assembly
- Beat together the softened cream cheese and butter until smooth. Gradually add the powdered sugar, mixing well, and finally mix in the vanilla and orange zest.
- Once the cakes are completely cooled, spread or pipe about 2 tablespoons of filling onto the flat side of one cake and top with a second cake.
Serving and Storage
- Serve the whoopie pies at room temperature or chilled in the refrigerator.
- Store leftovers in an airtight container in the refrigerator for up to 5 days.
Notes
Avoid overmixing the batter and ensure proper piping technique to prevent misshapen pies. Let cakes cool for at least 30 minutes before assembling.
