What Are Whoopie Pies?
If you’ve never heard of a whoopie pie before, you’re in for a treat! Whoopie pies, sometimes called “Gobs,” are made by sandwiching two soft, cake-like cookies with a luscious filling. The traditional version features chocolate cookies with vanilla buttercream, but they can come in a variety of flavors, including red velvet, pumpkin, and more.
These cakes were originally popularized in New England and Pennsylvania, where they were often packed as lunchbox treats. Over time, they gained nationwide fame, and now, they’re a staple in many bakeries across the U.S. Their delightful balance of cake and creamy filling makes them the perfect indulgence.
Ingredients for Whoopie Pies
Here’s everything you need to make these delicious whoopie pies:
For the Chocolate Cake Cookies:
- 1 ½ cups all-purpose flour
- 1 cup cocoa powder
- 1 ½ tsp baking powder
- 1 tsp baking soda
- ½ tsp salt
- 1 cup light brown sugar
- ½ cup oil (vegetable or canola)
- 1 large egg
- 1 tsp vanilla extract
- 1 tsp instant coffee powder
- ½ cup hot milk
For the Marshmallow Buttercream:
- ½ cup unsalted butter (softened)
- 2 cups powdered sugar
- 7 oz marshmallow fluff
- 1 tsp vanilla extract
How to Make Whoopie Pies
Step 1: Preheat the Oven
Preheat your oven to 350°F (180°C) for conventional baking. If using a convection oven, reduce the temperature by 25°F (about 10°C). Line three baking sheets with parchment paper (two half-sheet trays and one smaller tray work well).
Step 2: Mix Dry Ingredients
In a medium bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt. Whisk until well combined and set aside.
Step 3: Prepare Wet Ingredients
In a large bowl, whisk together the light brown sugar, oil, egg, vanilla extract, and instant coffee powder until smooth and well combined.
Step 4: Combine Dry and Wet Ingredients
Add the sifted dry ingredients to the wet mixture. Using a spatula, gently fold the ingredients together until just combined. The dough will be thick, similar to cookie dough, so gently push the dry ingredients into the wet mixture.
Step 5: Add Hot Milk
Pour in the hot milk and fold until the batter reaches a smooth, thick cake-like consistency.
Step 6: Scoop the Batter
Using a medium-sized spring-loaded cookie scoop (holding about 1 ½ tbsp of batter), portion the dough onto the prepared baking sheets. Space the scoops about 2 inches apart. If the scoops aren’t perfectly round, don’t worry—you can gently shape the edges with oiled fingers for a smooth round shape.
Step 7: Bake
Bake the cookies for 10 minutes, or until the tops are set and spring back when lightly touched. Allow the cookies to cool on the baking sheets for 15 minutes before carefully removing them and letting them cool completely.
Marshmallow Buttercream Filling
While the cookies cool, it’s time to make the marshmallow buttercream:
Step 1: Whip Butter and Sugar
In a large bowl, beat the softened butter and powdered sugar together using an electric hand mixer (or stand mixer with the paddle attachment). Mix on medium-high speed until light and fluffy.
Step 2: Add Marshmallow Fluff
Add the marshmallow fluff and vanilla extract to the butter-sugar mixture. Mix until smooth and combined. Avoid over-mixing to keep the texture light and airy.
Assembling the Whoopie Pies
Step 1: Prepare the Cookies
Place half of the cooled cookies upside down on a flat surface. Using the same medium-sized cookie scoop, place a dollop of the marshmallow buttercream on the flat side of each cookie.
Step 2: Fill and Sandwich
Take the remaining cookies, place them on top of the filled cookies (flat side down), and gently squeeze them together until the buttercream spreads to the edges.
Step 3: Enjoy!
Your whoopie pies are now ready to enjoy! The marshmallow filling will add a luscious, fluffy texture that complements the soft chocolate cookies perfectly.
How to Store Whoopie Pies

Pro Tips for the Best Whoopie Pies
- Do Not Overmix the Batter: To keep your cookies soft and cake-like, be sure to fold the batter until just combined.
- Chill the Dough (Optional): While chilling isn’t mandatory, it helps the dough firm up, making it easier to scoop.
- Make Sure the Cookies are Cooled Completely: This prevents the buttercream from melting when assembling the pies.
- Use Room Temperature Butter: For the marshmallow buttercream to whip up nicely, make sure the butter is softened but not melted.
