Ingredients You’ll Need

The ingredients here work together to create that classic chocolate-and-cream flavor combo that everyone loves in a whoopie pie. You’ll want to make sure you have good-quality cocoa powder for the best chocolate flavor, and fresh butter will make your buttercream dreamy and smooth.

• Vegetable Oil: Keeps the whoopie pies moist and tender without making them greasy.
• Brown Sugar: Adds a deep, caramel-like sweetness and rich moisture.
• Granulated White Sugar: Balances the sweetness and helps with structure.
• Egg: Binds everything together and adds richness.
• Vanilla Extract: Enhances the flavor in both the batter and frosting.
• Whole Milk: Provides moisture and richness; feel free to use buttermilk for a slight tangy twist.
• All-Purpose Flour: The base that holds the whoopie pies together; spoon and level it for accuracy.
• Cocoa Powder: Use unsweetened for a classic dark chocolate taste.
• Baking Soda & Baking Powder: For perfect rise and fluffiness.
• Salt: Balances sweetness and enhances flavor.
• Hot Water: I learned that adding hot water activates the cocoa and helps the batter stay smooth.
• Unsalted Butter: Essential for creamy, rich buttercream frosting.
• Powdered Sugar: For that silky, sweet frosting texture.
• Heavy Cream: Makes the buttercream light and fluffy.
• Halloween Sprinkles: For that festive finishing touch—the more colorful, the better!

Variations

I love how versatile this Halloween Whoopie Pies Recipe is. Once you get comfortable with the basic version, you can easily make tweaks to fit your mood, taste cravings, or dietary needs. Feel free to experiment—it’s part of the fun!

• Pumpkin Spice Whoopie Pies: Adding pumpkin pie spice and a bit of pumpkin puree to the batter makes for a lovely fall twist that my kids adored last year.
• Vegan Version: Swap vegetable oil for coconut oil, use flax eggs, and replace the butter with plant-based butter; the frosting can be done with vegan shortening and non-dairy milk.
• Peanut Butter Filling: Try mixing peanut butter into your buttercream for a salty-sweet surprise that’s always a hit at parties.
• Colorful Frosting Variations: Make multiple colors of frosting and assemble different Halloween character whoopie pies—my nieces loved the creativity!

How to Make Halloween Whoopie Pies Recipe

Step 1: Prepping the Batter

Begin by heating your oven to 350°F. I always line my baking sheets with parchment paper—it’s a little trick I discovered that makes the clean-up so much easier and prevents sticking. Then, stir together the vegetable oil, brown sugar, and white sugar until nice and smooth. Add your egg, vanilla, and milk, mixing just until you don’t see streaks of flour or sugar—don’t overmix, or the whoopie pies might get a bit tough. In another bowl, whisk your dry ingredients—flour, cocoa, baking powder, baking soda, and salt—then gradually add them to the wet mixture. Last but not least, stir in the hot water; it thins the batter just enough and unlocks a deeper cocoa flavor. Your batter should be smooth but thick enough to hold shape.

Step 2: Baking the Whoopie Pies

Scoop 1 ½ tablespoons of batter onto your lined baking sheets, spacing them about 2 inches apart because they spread out quite a bit while baking. This is where a cookie scoop comes in handy—makes sizing so much more consistent. Bake for about 9 to 11 minutes. You’ll know they’re ready when the tops look set and a toothpick inserted in the middle comes out clean. Let them cool on the pan for a bit before transferring them to wire racks to cool completely—I learned that moving them too soon can make them fall apart!

Step 3: Making the Festive Buttercream

While the whoopie pies cool, whip up your buttercream. Beat together the butter and powdered sugar on a low speed until roughly combined, then add the heavy cream, vanilla, and salt. Crank the mixer to medium speed and beat for 3-4 minutes until your frosting is light, airy, and fluffy. Don’t rush this part—properly whipped buttercream makes all the difference in texture. Then add a few drops of orange (or mix red and yellow) food coloring and gently fold it in for a perfect Halloween vibe. Transfer the frosting into a piping bag or a ziplock bag with the tip snipped off for easy assembly.

Step 4: Assembling Your Halloween Whoopie Pies

Flip one cookie over, so the flatter “bottom” is facing up, and pipe a generous amount of frosting onto it. The thickness is totally up to you—I like a generous layer because it balances the rich chocolate perfectly. Top with a matching cookie, domed side facing up, to sandwich everything. For a festive pop, pour some Halloween sprinkles on a shallow plate and gently roll the edges of the frosting in them. I love how it adds that extra crunch and color, making them totally party-ready. Pop the whoopie pies back onto your sheet tray and refrigerate for about an hour if you want the frosting to set firm. Or just dive right in—warm or chilled, they’re fantastic!

How to Serve Halloween Whoopie Pies Recipe

Garnishes

I love topping these whoopie pies with classic Halloween sprinkles—think mini pumpkins, bats, and orange-and-black nonpareils. Sometimes I’ll add edible glitter or tiny candy eyeballs for a quirky twist my friends adore. These little touches turn a simple dessert into an unforgettable Halloween centerpiece.

Side Dishes

Pair your Halloween Whoopie Pies with warm apple cider or a rich hot chocolate for the ultimate seasonal treat spread. I also love serving them alongside simple pumpkin muffins or spiced nuts for a variety that keeps everyone coming back for more.

Creative Ways to Present

One year, I arranged these whoopie pies on a tiered cake stand decorated with mini pumpkins and cobwebs—it made for a festive and fun display. You could also wrap individual pies in cellophane with a Halloween ribbon for party favors or school treats. Another fun idea is to pipe the frosting in fun shapes or colors and add spooky faces with edible markers.

Make Ahead and Storage

Storing Leftovers

Once assembled, I keep leftover whoopie pies in an airtight container in the fridge. They stay fresh and delicious for about 3 to 4 days. Leaving them chilled actually improves the texture of the frosting and keeps everything nicely firm.

Freezing

If you want to make these ahead of time, freeze the baked cookies separately on a baking sheet until solid, then transfer them to a freezer bag. Freeze the buttercream in an airtight container as well. When you’re ready, thaw everything overnight in the fridge and assemble—the results will still feel fresh and homemade.

Reheating

Since these are best served chilled, I don’t usually reheat them. However, if you want your cookies slightly warm, pop the cookie halves (without frosting) in the microwave for 10-15 seconds before assembling. Keep the frosting cool for the best texture and flavor.
