Whoopie Pies

Whoopie pies are a classic dessert made of two soft, cakey chocolate rounds sandwiched around a creamy, sweet filling. Some call them cookies, others call them cakes, but one thing’s for sure—these little treats are irresistible. With a rich, tender texture and a nostalgic flavor, they’re a fun and comforting bake that brings smiles every time.

Why You’ll Love This Recipe

I love this whoopie pie recipe because it blends the fluffiness of cake with the convenience of a handheld treat. The chocolate cakes are moist and soft, not too sweet, which makes the creamy filling shine. They’re perfect for celebrations, lunchboxes, or even freezing for later. Plus, I don’t need any fancy tools or techniques—just some mixing, baking, and assembling.

ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

chocolate cakes:

• all-purpose flour
• unsweetened cocoa powder
• baking soda
• salt
• unsalted butter
• granulated sugar
• egg
• vanilla extract
• whole milk or buttermilk

filling:

• unsalted butter

• powdered sugar

• marshmallow fluff or cream

• vanilla extract

directions

1. I start by preheating my oven and lining baking sheets with parchment paper.

2. In one bowl, I whisk together the dry ingredients: flour, cocoa powder, baking soda, and salt.

3. In a separate bowl, I beat the butter and sugar until light and fluffy. I then add the egg and vanilla, mixing until smooth.

4. I alternate adding the dry ingredients and milk to the wet mixture, mixing just until combined.

5. Using a cookie scoop, I drop mounds of batter onto the prepared baking sheets, spacing them apart.

6. I bake until the cakes spring back when touched, then let them cool completely.

7. While the cakes cool, I beat the butter, powdered sugar, marshmallow fluff, and vanilla until light and creamy.

8. To assemble, I spread or pipe the filling on the flat side of one cake and top it with another to make a sandwich.

Servings and timing

This recipe typically makes about 10 to 12 whoopie pies, depending on how big I make them.
Prep time: 20 minutes
Cook time: 10–12 minutes
Total time: Around 40 minutes including assembly

Variations

• I sometimes swap out the chocolate cake for a pumpkin or red velvet version for seasonal twists.

• I like to add crushed peppermint or cocoa powder to the filling during the holidays.

• A peanut butter or cream cheese filling also pairs really well with the chocolate cakes.

• For mini versions, I use a smaller scoop to make bite-sized pies—perfect for parties.

• I’ve even dipped the edges in sprinkles or mini chocolate chips for extra fun.

storage/reheating

I store whoopie pies in an airtight container at room temperature for up to 2 days, or in the fridge for up to 5 days. If I refrigerate them, I let them sit at room temperature for about 15–20 minutes before serving so the filling softens.
For longer storage, I freeze them individually wrapped in plastic wrap and then place them in a freezer bag. They last up to 2 months this way and thaw well at room temp.

FAQs

What is the filling made of in a whoopie pie?

I use a mix of butter, powdered sugar, marshmallow fluff, and vanilla extract to make a light and fluffy filling. Some recipes use cream cheese or shortening instead.

Can I make whoopie pies ahead of time?

Yes, I often make the cakes a day ahead and store them in an airtight container. I add the filling and assemble them just before serving or store fully assembled pies in the fridge.

How do I keep whoopie pies from being dry?

I make sure not to overbake the cakes—removing them when they just spring back ensures they stay soft and moist. Also, using buttermilk helps keep the texture tender.

Can I use boxed cake mix for the whoopie pies?

I’ve seen people use boxed mix as a shortcut, and it can work, but I prefer the texture and flavor of homemade batter. It really makes a difference.

Do whoopie pies need to be refrigerated?

They don’t have to be if eaten within a day or two, but I refrigerate them if I’m keeping them longer. The filling stays firmer and the cakes stay fresh.

Conclusion

These whoopie pies are a nostalgic treat that I always enjoy baking and sharing. With rich chocolate flavor and a creamy, fluffy center, they hit the sweet spot between cookie and cake. Whether I’m making them for a special occasion or just to satisfy a craving, they’re always a hit—and I love how easy they are to make from scratch.
