Key Ingredients for Halloween Whoopie Pies

See recipe card below for full list of measurements, ingredients, and instructions.

Cocoa Powder

Cocoa powder is what gives these whoopie pies their decadent, deep chocolate flavor and classic dark color. For the richest taste, opt for unsweetened natural cocoa powder. Dutch-processed cocoa will work too, but may give a slightly different flavor profile. Make sure to sift the cocoa so your cookies bake up smooth and lump-free.

Buttermilk

Buttermilk keeps the cookies ultra-moist and tender with just the right hint of tang. If you don’t have buttermilk on hand, make a quick substitute by adding 1 tablespoon of lemon juice or white vinegar to 1 cup of milk and letting it sit for 5 minutes. You can also use plain yogurt thinned with a splash of milk.

Marshmallow Creme

This is the fluffy secret to that irresistible, cloud-like filling! Marshmallow creme (or fluff) makes the center sweet, light, and delightfully sticky. Look for it in jars near the baking aisle. If you can’t find it, you can blend mini marshmallows with a little butter over low heat as a substitute.

Food Coloring

Food coloring transforms the filling into bright orange, green, or purple—absolutely perfect for Halloween! Gel food colors give the most vibrant results without thinning out your filling. You can go classic orange and black, or get creative with any spooky color combo you love.

Festive Sprinkles

Halloween-themed sprinkles add a fun, crunchy finish and really make these whoopie pies pop on the dessert table. Use black, orange, purple, or even candy eyeballs! Feel free to skip or swap based on your own festive flair.

Instructions for Halloween Whoopie Pies

See recipe card below for full list of measurements, ingredients, and instructions.

Preheat and Prep

Start by preheating your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats—this helps prevent sticking and keeps your cookies perfectly shaped.

Mix the Dry Ingredients

In a medium bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt. Set aside. This step ensures your cookies rise evenly and have a deep chocolatey flavor in every bite.

Cream Butter and Sugar

In a large mixing bowl, beat together the softened butter and brown sugar until light and fluffy, about 2 minutes. Add the egg and vanilla, and beat until well combined.

Combine Wet and Dry Mixtures

Add the dry ingredients to the butter mixture in three parts, alternating with the buttermilk. Begin and end with the dry mixture, and mix just until combined—don’t overmix or your cookies may turn out tough.

Scoop and Bake

Use a small ice cream scoop or tablespoon to drop 1 1/2-inch rounds of batter onto your prepared baking sheets, spacing them about 2 inches apart. Bake for 10-12 minutes, until the cookies are puffed and spring back when gently pressed. Let them cool on the tray for 5 minutes before transferring to a wire rack.

Make the Marshmallow Filling

While the cookies cool, prepare the filling. In a clean bowl, beat together the softened butter and marshmallow creme until smooth. Gradually add the powdered sugar and vanilla, beating until fluffy. Divide the filling and tint with food coloring as desired.

Assemble and Decorate

Once your cookies are completely cool, spread or pipe about 2 tablespoons of colored filling on the flat side of half the cookies. Top with another cookie to create a sandwich. Roll the edges in festive sprinkles for extra Halloween flair.

Recipe Variations

Candy Corn Filling

Give your whoopie pies a candy corn vibe by dividing the marshmallow filling into three bowls and coloring each orange, yellow, and white. Pipe the colors in stripes for a fun, layered look that screams Halloween!

Gluten-Free Option

Swap the all-purpose flour for a 1:1 gluten-free baking flour blend. The cookies will remain soft and delicious—no one will even guess they’re gluten-free!

Vegan Twist

For a plant-based version, use a vegan butter alternative and certified vegan marshmallow creme. Replace the egg with a flax egg (1 tablespoon flaxseed meal + 2.5 tablespoons water, mixed and set for 5 minutes).

Spiced Chocolate Cookies

Add 1/2 teaspoon ground cinnamon and a pinch of nutmeg to your dry ingredients. The subtle spice makes these whoopie pies taste extra cozy and autumnal.

Serving Suggestions

Halloween Whoopie Pies are fantastic on their own, but they’re even better alongside a cup of hot cocoa or apple cider. For a party platter, serve with bowls of candy corn, caramel popcorn, or sliced apples. Add a spooky touch by garnishing your platter with gummy worms or candy eyeballs for kids!

Storage and Reheating

Store assembled whoopie pies in an airtight container at room temperature for up to 2 days, or in the fridge for up to 5 days. For best texture, let chilled pies sit at room temp for 15-20 minutes before serving. You can freeze the unfilled cookies for up to 2 months; thaw, fill, and decorate just before enjoying. Avoid freezing assembled pies, as the filling can get sticky.

Frequently Asked Questions About Halloween Whoopie Pies (FAQ)

Q: Can I make the whoopie pies ahead of time?
A: Yes! You can bake the cookies a day or two in advance and store them tightly covered. Fill and decorate them the day you plan to serve for best freshness.

Q: Can I use store-bought frosting instead of marshmallow filling?
A: Absolutely—store-bought vanilla or cream cheese frosting works in a pinch. The texture will be a bit thicker, but still delicious.

Q: How do I get perfectly round whoopie pies?
A: Use a small cookie scoop or pipe the batter in circles for uniform size. Chilling the batter for 15 minutes before baking can also help them hold their shape.
