Classic Whoopie Pies Recipe – Soft, Chocolatey, and Creamy

There’s something purely joyful about biting into a Whoopie Pie — soft, cakey chocolate rounds sandwiched around a sweet, creamy filling. Part cookie, part cake, and completely nostalgic, this treat has been delighting dessert lovers for generations.

Originating from the Northeast (especially Maine and Pennsylvania), Whoopie Pies were once known as “gobs.” Legend says Amish bakers used leftover cake batter to make handheld treats — and the name “whoopie” came from the joy people felt when they found them in their lunchboxes.

Today, they’re still a comforting favorite — a perfect combination of tender chocolate cake and fluffy cream that’s fun to bake and even more fun to eat.

The Secret to Perfect Whoopie Pies

The magic of a great Whoopie Pie lies in its texture balance. The cakes should be soft and moist, not dry or crumbly, while the filling should be fluffy but stable enough to hold its shape.

Using buttermilk keeps the cakes tender and slightly tangy, while cocoa powder provides rich chocolate flavor. For the filling, a mix of marshmallow fluff and buttercream creates the classic smooth, sweet center.

Each bite delivers that signature contrast — airy chocolate and creamy vanilla — without being overly heavy.

Ingredients List

For the Chocolate Cakes:

2 cups all-purpose flour
½ cup unsweetened cocoa powder
1 ½ tsp baking soda
½ tsp salt
1 cup granulated sugar
1 cup buttermilk
½ cup unsalted butter, softened
1 large egg
2 tsp vanilla extract
½ cup hot water

For the Cream Filling:

1 cup marshmallow fluff
½ cup unsalted butter, softened
1 cup powdered sugar
1 tsp vanilla extract
Pinch of salt

Step-by-Step Instructions

Step 1: Preheat and Prepare

Preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper or silicone mats.

This step ensures your whoopie pies bake evenly and lift off the sheet easily once cooled.

Pro Tip: Parchment helps prevent spreading and keeps the cookies perfectly round.

Step 2: Make the Chocolate Batter

In a medium bowl, whisk together flour, cocoa powder, baking soda, and salt.

In a separate large mixing bowl, beat butter and sugar together using an electric mixer until light and fluffy — about 2 minutes. Then add the egg and vanilla extract, beating until combined.

Next, alternate adding the dry ingredients and buttermilk, starting and ending with the dry mix. Pour in the hot water last and mix just until smooth and glossy.

Pro Tip: The batter should be thick but scoopable, similar to brownie batter. Avoid overmixing to keep the cakes tender.

Step 3: Scoop and Bake

Using a 1½-inch cookie scoop, drop mounds of batter onto the prepared baking sheets, spacing them about 2 inches apart.

Bake for 10–12 minutes, or until the tops spring back when lightly touched.

Cool completely on wire racks before filling — this prevents the filling from melting.

Step 4: Make the Creamy Filling

In a medium bowl, beat butter until smooth. Add marshmallow fluff and beat until light and creamy. Gradually mix in powdered sugar, vanilla, and a pinch of salt until smooth and spreadable.

If the filling feels too thick, add a teaspoon of milk. If it’s too soft, chill it for a few minutes before spreading.

Step 5: Assemble the Whoopie Pies

Match similar-sized cakes in pairs. Spread or pipe about 2 tablespoons of filling onto the flat side of one cake, then top with its partner, pressing gently to spread the filling evenly.

Repeat with the remaining cakes until you have a batch of beautiful, creamy whoopie pies.

Pro Tip: For bakery-style presentation, use a piping bag for even, neat filling.

Flavor Variations

Whoopie pies are endlessly customizable! Try one of these fun twists:

Pumpkin Spice Whoopie Pies: Substitute pumpkin purée for half the buttermilk and add cinnamon, nutmeg, and ginger.
Peanut Butter Filling: Replace half the butter with creamy peanut butter for a rich twist.
Mint Chocolate Whoopie Pies: Add ½ teaspoon of peppermint extract to the filling and tint it pale green.
Red Velvet Whoopie Pies: Add red food coloring and reduce cocoa powder slightly for a festive version.

Each variation keeps the fun spirit of the original while adding a new flavor profile.

Storage & Reheating Tips

Room Temperature: Store in an airtight container for up to 3 days.
Refrigerator: Keep for up to 1 week — bring to room temp before serving.
Freezer: Wrap individually and freeze for up to 2 months. Thaw overnight in the fridge.

Pro Tip: Place parchment between layers to keep the pies from sticking together.

Common Mistakes & How to Avoid Them

Overbaking the cakes: They should be soft and slightly springy — not dry.
Warm filling: Always cool the cakes completely before adding filling.
Runny filling: Chill your butter and fluff mixture slightly before piping.
Uneven sizes: Use a cookie scoop for consistent shapes and even baking.

Follow these tips, and your whoopie pies will come out picture-perfect every time.
