Ingredients

Scale

For the Cake:

  • 2 cups all-purpose flour
  • ½ cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 tablespoon instant espresso powder
  • ½ cup unsalted butter, softened
  • 1 cup granulated sugar
  • 1 large egg, room temperature
  • 1 teaspoon vanilla extract
  • 1 cup milk
  • ½ cup strongly brewed coffee, cooled

For the Filling:

  • ¾ cup unsalted butter, softened
  • 3 cups powdered sugar
  • 1 tablespoon instant espresso powder
  • 1 tablespoon hot milk or water
  • 1 teaspoon vanilla extract
  • 12 tablespoons milk (as needed for consistency)

Instructions

  1. Preheat and Prepare Baking Sheets: Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper to prevent sticking and facilitate easy cleanup.
  2. Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking soda, salt, and instant espresso powder until well combined. Set aside.
  3. Cream Butter and Sugar: In a large bowl, beat the softened butter and granulated sugar using a mixer until the mixture is light and fluffy, about 2 to 3 minutes. This ensures a tender cake texture.
  4. Add Egg and Vanilla: Beat in the large egg and vanilla extract into the butter and sugar mixture until fully incorporated and smooth.
  5. Combine Milk and Coffee: In a separate measuring cup, mix the milk and cooled brewed coffee. This liquid mixture adds moisture and enhances the coffee flavor in the cakes.
  6. Combine Wet and Dry Ingredients: Add the dry ingredients to the wet ingredients in two additions, alternating with the milk-coffee mixture. Mix gently until just combined to avoid overmixing, which can toughen the cakes.
  7. Scoop Batter onto Sheets: Using about 2 tablespoons of batter per scoop, place dollops onto the prepared baking sheets, spacing them about 2 inches apart to allow room for spreading.
  8. Bake the Cakes: Bake in the preheated oven for 10 to 12 minutes or until the cakes are set and spring back lightly when touched. The cakes should be soft but firm enough to handle.
  9. Cool the Cakes: Remove the baking sheets from the oven and transfer the cakes to a wire rack to cool completely before filling, ensuring the filling does not melt.
  10. Prepare the Filling: Dissolve the instant espresso powder in the hot milk or water to enhance the coffee flavor in the frosting.
  11. Make the Buttercream: Beat the softened butter until smooth and creamy. Gradually add the powdered sugar, beating well after each addition for a light texture.
  12. Add Espresso Mixture and Vanilla: Pour in the dissolved espresso mixture and vanilla extract, then beat until the filling is light, fluffy, and well combined. If the filling is too thick, add 1-2 tablespoons of milk to reach a smooth, spreadable consistency.
  13. Assemble the Whoopie Pies: Spread or pipe the filling onto the flat side of half of the cooled cakes. Top with the remaining cakes, flat side down, gently pressing to create sandwich cookies.

Notes

  • For stronger coffee flavor, increase the instant espresso powder slightly in either the batter or filling.
  • Ensure cakes are completely cooled before adding the filling to prevent melting.
  • Whoopie pies can be stored in an airtight container in the refrigerator for up to 3 days.
  • Allow refrigerated whoopie pies to come to room temperature before serving for best texture.
  • Use parchment paper for easy removal and cleanup.
