What Ingredients are in Chocolate Peanut Butter Whoopie Pies?
These classic treats come together with pantry staples that create the perfect balance of chocolate and peanut butter flavors.
For the Chocolate Cookies:
- 1/2 cup melted butter
- 1 cup brown sugar
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 3/4 teaspoon salt
- 1 teaspoon vanilla extract
- 1 egg
- 1/2 cup cocoa powder
- 2 1/3 cups all-purpose flour
- 1 cup milk
For the Peanut Butter Filling:
- 1/2 cup melted butter
- 1 cup creamy peanut butter
- 2 cups powdered sugar
- 2 tablespoons milk
When shopping for these ingredients, I recommend using a high-quality cocoa powder and creamy peanut butter (not the natural kind that separates) for the best flavor and texture in your whoopie pies.
How to Make these Chocolate Peanut Butter Whoopie Pies
Preheat your oven to 350°F and line baking sheets with parchment paper or lightly grease them. Getting your oven to the right temperature before mixing guarantees those whoopie pies will rise properly.
Step 2: Mix the Wet Ingredients
In a large bowl, combine 1/2 cup melted butter and 1 cup brown sugar until smooth and well incorporated.
Add 1 egg and 1 teaspoon vanilla extract, mixing until the batter becomes light and slightly fluffy.
Step 3: Combine Dry Ingredients
In a separate bowl, whisk together 2 1/3 cups flour, 1/2 cup cocoa powder, 1 teaspoon baking powder, 1/2 teaspoon baking soda, and 3/4 teaspoon salt.
This pre-mixing helps distribute the leavening agents evenly throughout your batter.
Step 4: Create the Batter
Gradually add the dry ingredients to the wet mixture, alternating with 1 cup milk, beginning and ending with the dry ingredients.
The batter should be thick but still slightly sticky—kinda like a cross between cake batter and cookie dough.
Step 5: Scoop and Bake
Drop 1/4 cup portions of batter onto your prepared baking sheets, leaving about 2 inches between each to allow for spreading.
Bake for 11-13 minutes, or until the tops spring back when lightly touched.
Step 6: Cool Completely
Allow the chocolate cakes to cool on the baking sheets for 5 minutes, then transfer to wire racks to cool completely.
Patience is key here—if they’re still warm when you add the filling, you’ll end up with a melty mess.
Step 7: Make the Peanut Butter Filling
While the cakes cool, beat together 1/2 cup melted butter and 1 cup creamy peanut butter until smooth.
Using a professional kitchen mixer stand will give you the perfect consistency and save you time during this crucial step.
Gradually add 2 cups powdered sugar and 2 tablespoons milk, mixing until you achieve a creamy, spreadable consistency.
Step 8: Assemble Your Whoopie Pies
Pair similar-sized cakes together, spread a generous dollop of peanut butter filling on the flat side of one cake, and sandwich with another cake.
Gently press them together so the filling spreads to the edges without squeezing out.
What to Serve with Chocolate Peanut Butter Whoopie Pies
These indulgent whoopie pies make a perfect afternoon treat or dessert, but they don’t have to stand alone!
For a cozy coffee shop vibe at home, pair them with a tall glass of cold milk or a steaming mug of coffee—the dairy cuts through the richness beautifully.
If you’re feeling fancy, serve alongside fresh berries for a tart contrast that balances the sweetness. A scoop of vanilla ice cream transforms these into a next-level dessert, while a small dish of extra peanut butter filling makes for delightful dipping.
For brunch, these work surprisingly well with savory bacon—that sweet-salty combination is unbeatable.
They’re substantial enough to be the star of your dessert table, no additional fuss required.
Chocolate Peanut Butter Whoopie Pies Substitutions and Variations
- Holiday twist: Fold crushed candy canes into the filling for Christmas, or add orange zest to the batter for Halloween.
- Finishing touches: Dip half the assembled whoopie pie in melted chocolate, roll edges in chopped nuts, or dust with cocoa powder.
- Healthier option: Reduce sugar by 1/4 cup and use Greek yogurt instead of milk in the filling for extra protein.
Leftovers and Storage for these Chocolate Peanut Butter Whoopie Pies
These decadent treats stay remarkably fresh when stored properly. For best results:
- Store assembled whoopie pies in an airtight container with parchment paper between layers to prevent sticking. They’ll keep at room temperature for 2-3 days.
- For longer storage, refrigerate for up to a week. The peanut butter filling actually firms up nicely in the fridge, giving them an almost ice-cream sandwich quality.
- Freezing works beautifully too! Wrap each pie individually in plastic wrap, then place in a freezer bag for up to 3 months. Thaw at room temperature for about an hour before enjoying.
- To refresh day-old pies, microwave for 10 seconds to restore that just-baked softness.
While delicious fresh, many bakers swear these taste even better the next day when the flavors have had time to meld!
