    Chocolate Whoopie Pies are basically just a way to indulge in a thick smear of sweet, creamy buttercream filling using two soft, cakey cookies as the mode of transportation to your mouth.

    They're rich, indulgent and -- most importantly -- portable and easy to serve, making it an ideal treat to take to potlucks and celebrations.

    This Halloween version came to be when I was asked to review a copy of The Easy Homemade Cookie Cookbook several years ago, and came across a plain version that was asking for a monstrous makeover!

    I used food dye, melted chocolate, candy eyes and mini marshmallows to add some frighteningly fun details to these whoopie pies that lean more towards cute than creepy!

    This recipe is naturally vegetarian and can be made gluten-free. See Variations & Substitutions area below.

    Ingredients

    The ingredient list for these whoopies pies might seem long, but that's only because there are three parts: Cake, frosting and decorations. Here's what you'll need:

    • All-purpose flour
    • Unsweetened cocoa powder
    • Baking powder
    • Baking soda
    • Sea salt
    • Unsalted butter
    • Light brown sugar
    • Granulated sugar
    • Eggs
    • Vanilla extract
    • Buttermilk
    • Confectioners’ sugar
    • Milk
    • Mini marshmallows
    • Candy eyes
    • White chocolate
    • Green food coloring

    Instructions

    Make the cakes/cookies

    Preheat the oven to 350F. Line a cookie sheet with parchment paper.

    In a medium mixing bowl, sift or whisk together the flour, cocoa powder, baking powder, baking soda, and salt.

    In a large mixing bowl, beat together the butter and both sugars until light and creamy, about 3 minutes.

    Add the eggs and vanilla, and beat to combine. Add the buttermilk and dry ingredients in alternating batches, beating on low speed until incorporated.

    Using a medium (1 ½ tablespoon) cookie scoop, scoop the batter and drop about 2 inches apart on the prepared cookie sheet.

    Bake for 13 to 14 minutes, until they're puffed and set and the tops are slightly cracked.

    Let the cookies rest on the cookie sheets for 5 minutes before transferring them to wire racks to cool completely.

    Make the Filling

    In a large bowl, beat together the butter, confectioners’ sugar, milk, and vanilla until light and fluffy, 1 to 2 minutes. Stir in a few drops of green food coloring to tint the buttercream until the desired color is achieved.

    Transfer the filling to a piping bag or a zip-top bag with one corner snipped. Once the cookies are completely cooled, pipe a swirl on the bottom (flat) side of half of the whoopie pies. Add the top cookies, flat-side down, and gently press together.

    Decorate

    Carefully press two candy eyes into the buttercream. Place one mini marshmallow on each side of the eyes to create Frankenstein's "bolts".

    Use white chocolate to pipe "sutures" on one side to complete the monster look.

    Recipe FAQ's

    What is whoopie pie filling made of?

    Whoopie pies usually have a sweet, creamy filling. Most are made with either buttercream or a marshmallow crème filling.

    Can whoopie pies be made ahead?

    Yes. Make the whoopie pies as directed, place in an airtight container and refrigerate for up to 3 days, or keep at room temperature for 4 hours. Alternatively, whoopie pie elements can be made ahead (refrigerate buttercream), and assembled the day they will be eaten.

    Can whoopie pies be frozen?

    Yes. Whoopie pies are just like layer cakes and freeze beautifully. Place in an airtight, freezer-safe container and freeze for up to 2 months. Simply thaw overnight in the refrigerator or at room temperature for a few hours to defrost and enjoy.

    Variations & Substitutions

    Try these variations for a fun twist:

    • Change up the flavor of the buttercream filling! Try adding a pinch of ground cinnamon, flavored extracts such as almond or peppermint, or a few tablespoons of marshmallow crème.
    • Add an extra special filling: Pipe a buttercream "wall" around the exterior of the whoopie pie and fill the center with jam, Nutella or ganache.
    • Skip the Frankenstein decor and roll the edges in colorful, festive sprinkles.

    Diet-Specific Substitutions

    • Gluten-Free: Use your favorite one-to-one gluten-free flour blend in place of all-purpose.
    • Vegan/Dairy-Free: I have not personally made these with plant-based substitutes, but if you do try substituting the butter, eggs and buttermilk for plant-based versions and have a good result, let me know!

    Instructions
     

    • In a medium mixing bowl, sift or whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
    • In a large mixing bowl, beat together the butter and both sugars until light and creamy. This will take about 3 minutes if using an electric mixer or 5 to 6 minutes if creaming by hand.

    To Make the Filling:

    • In a large bowl, beat together the butter, confectioners’ sugar, milk, and vanilla until light and fluffy, 1 to 2 minutes.
    • Transfer the filling to a resealable plastic bag and snip off one corner of the bag. Once the cookies are completely cooled, pipe a swirl on the bottom (flat) side of half of the whoopie pies.
    • Add the top cookies, flat-side down, and gently press together.

    Decorate

    • To "Monsterfy" your Whoopie Pies, simply tint your frosting with some green food coloring before piping. Place 2 candy eyes on each whoopie pie, and 2 mini marshmallows on each side to make Frankenstein's "bolts." Finish off by piping "stitches" using melted white chocolate or frosting.
