Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper.

1. In a bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt.

3. Pipe or Scoop the Cookies

Use a cookie scoop or spoon to drop tablespoon-sized dollops onto the prepared baking sheets. Leave space for spreading.

3. Add vanilla and 1–2 tablespoons of milk to achieve a smooth, spreadable consistency.

Tips for Perfect Whoopie Pies

• Even sizes: Use a cookie scoop for uniform cakes.

• Cool completely: Ensure cookies are cooled before filling to prevent melting the buttercream.

• Make ahead: Cakes can be baked a day in advance; assemble just before serving.

• Optional coatings: Roll the edges in sprinkles or crushed nuts for a festive touch.
