Easy Cake Mix Whoopie Pie Recipe


    For the Whoopie Pies:

    • 1 box of chocolate cake mix (15.25 oz)
    • 1/2 cup vegetable oil
    • 2 large eggs
    • 1/4 cup water

    For the Filling:

    • 1/2 cup unsalted butter, softened
    • 1 cup powdered sugar
    • 1 teaspoon vanilla extract
    • 1 cup marshmallow fluff or marshmallow cream


    Preheat the Oven:

    • Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.

    Prepare the Cake Mix:

    • In a large mixing bowl, combine the chocolate cake mix, vegetable oil, eggs, and water.
    • Mix until well combined and a smooth batter is formed.

    Portion the Batter:

    • Using a cookie scoop or tablespoon, drop rounded portions of the batter onto the prepared baking sheets, spacing them about 2 inches apart.


    • Bake in the preheated oven for 10-12 minutes or until the edges are set.
    • The cookies should be soft and cake-like.


    • Allow the cookies to cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.

    Make the Filling:

    • In a mixing bowl, beat together the softened butter, powdered sugar, and vanilla extract until smooth and creamy.
    • Add the marshmallow fluff and continue to beat until the filling is light and fluffy.

    Assemble the Whoopie Pies:

    • Once the cookies are completely cooled, match them up into pairs of similar size.
    • Spread a generous dollop of the marshmallow filling on the flat side of one cookie and then sandwich it with another cookie.
    • Repeat this process for all the cookie pairs, creating your whoopie pies.

    Serve and Enjoy:

    • Serve these delightful and easy cake mix whoopie pies immediately or store them in an airtight container.
    • They can be enjoyed at room temperature or chilled.


    • You can roll the edges of the assembled whoopie pies in sprinkles, coconut flakes, or chopped nuts for added texture and flavor.
