Whoopie Pies
These classic chocolate whoopie pies feature soft, cake-like cookies sandwiching a sweet marshmallow center. The batter comes together quickly with melted baking chocolate and buttermilk for a rich, tender crumb. A fluffy filling made from marshmallow creme, butter, and powdered sugar holds the two halves together. They make a fun weekend baking project or a nostalgic treat for parties and bake sales.
Ingredients
- 1 cup granulated sugar
- ½ cup butter, softened
- ½ cup buttermilk
- 2 teaspoons vanilla
- 1 egg
- 2 oz unsweetened baking chocolate, melted and cooled
- 1 ¾ cups all-purpose flour
- ½ teaspoon baking soda
- ½ teaspoon salt
- 3 cups powdered sugar
- 1 jar (7 oz) marshmallow creme
- ¾ cup butter, softened
- 6 to 7 teaspoons milk
Instructions
- 1Preheat the oven to 400°F and prepare your cookie sheets by greasing them or lining them with parchment paper.
- 2Combine the granulated sugar, one-half cup of softened butter, buttermilk, vanilla, egg, and melted chocolate in a large bowl, beating on medium speed until smooth.
- 3Mix the flour, baking soda, and salt into the wet ingredients until just combined, then drop rounded tablespoons of dough onto the prepared baking sheets about two inches apart.
- 4Bake the cookies for 8 to 10 minutes until the centers spring back when lightly touched, then transfer them to wire racks to cool for 30 minutes.
- 5Whip the powdered sugar, marshmallow creme, three-quarters cup of softened butter, and milk in a large bowl on medium speed for about two minutes until light and fluffy.
- 6Spread nearly three tablespoons of the marshmallow filling onto the flat side of one cookie and press a second cookie on top, storing the finished pies in a sealed container.
- 7For a chocolate chip version, fold one-half cup of miniature semisweet chocolate chips directly into the prepared marshmallow filling.
- 8To make a peppermint variation, mix six drops of red food coloring into the filling and roll the edges of the assembled pies in crushed peppermint candies.
- 9Create a toffee version by stirring one-half cup of chocolate-covered toffee bits into the fluffy marshmallow center.
- 10Prepare the pink peppermint whoopie pies as directed if choosing that flavor variation.
- 11Ensure you bake the cookies until almost no indentation remains when touched lightly in the center.
- 12Finish by placing the flat sides of two cookies together with the filling to create a sandwich style treat.
