How to Make Homemade Chocolate Whoopie Pies with Marshmallow Fluff Filling Recipe

Step 1: Prep Oven and Baking Sheets

Get started by positioning your oven rack in the middle and preheating the oven to 350 degrees Fahrenheit. Line your baking sheets with silicone mats or parchment paper to prevent sticking and to ensure even baking. This little prep step makes a huge difference in your final cookies’ texture and keeps cleanup a breeze.

Step 2: Mix the Dry Ingredients

In a medium bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking soda, baking powder, and salt. This dry mix provides the framework for your chocolatey goodness and guarantees every bite is perfectly balanced.

Step 3: Cream the Wet Ingredients

In a large mixing bowl, beat together the granulated sugar and vegetable oil until crumbly. This combination acts as the base for the moist texture you’re aiming for. Then add the eggs one at a time, followed by the milk and vanilla extract, beating after each addition until smooth and silky.

Step 4: Combine Dry and Wet

Gradually add your dry ingredients to the wet mixture, beating gently after each addition. You’re aiming for a smooth, well-incorporated dough that holds together but isn’t too stiff—this is what makes the whoopie pies soft and tender rather than dense.

Step 5: Scoop and Shape the Cookies

Using a 2-tablespoon cookie scoop, portion the dough into balls and place them roughly three inches apart on your prepared baking sheets. Gently press each ball down with your palm to create a flatter surface for perfect sandwich construction later on.

Step 6: Bake the Cookies

Bake the cookies for 7 to 10 minutes, rotating the pans halfway through baking to ensure even heat distribution. Look for cookies that are firm around the edges but still soft in the center—just what you want for the ideal whoopie pie shell.

Step 7: Cool Completely

After removing the trays from the oven, let the cookies cool on the pan for about 5 minutes before transferring them to a wire rack to cool completely. Patience here pays off; warm cookies won’t hold the filling well and may lose their signature tender crumb.

Step 8: Prepare the Marshmallow Fluff Filling

While your cookies cool, whip together softened butter and powdered sugar in a medium bowl until light and fluffy. Add vanilla extract and salt, then fold in the marshmallow fluff until smoothly combined. Chill the filling in the fridge for 20 to 30 minutes—this step helps it firm up so it pipes neatly onto your cookies.

Step 9: Assemble the Whoopie Pies

Fit a piping bag with a large round tip and fill it with your marshmallow fluff mixture. Pipe generous dollops onto the flat side of half of the chocolate cookies. Top each with a second cookie, gently pressing to create the perfect sandwich. That’s it—your Homemade Chocolate Whoopie Pies with Marshmallow Fluff Filling Recipe is ready to enjoy!

Garnishes

While these whoopie pies shine all on their own, adding a simple garnish can elevate their presentation. A dusting of powdered sugar or a few sprinkles of mini chocolate chips on top adds an inviting touch. For a festive flair, dip the edges of the pies lightly in melted chocolate or crushed nuts before the filling sets. These little extra steps make a big visual impact, especially if you’re serving guests or gifting your treats.

Side Dishes

Pair your whoopie pies with a scoop of smooth vanilla ice cream or a dollop of whipped cream for a classic dessert duo. If you’re enjoying them as an afternoon snack, a hot cup of coffee or a glass of cold milk complements the rich chocolate and sweet marshmallow perfectly. These pairings balance the sweetness and keep every bite interesting.

Make Ahead and Storage

Storing Leftovers

The great news is that these whoopie pies stay wonderfully fresh when stored properly. Keep them in an airtight container at room temperature for up to three days. If your kitchen is especially warm, refrigerate them to keep the marshmallow filling from getting too soft, though allow them to come back to room temperature before serving to enjoy their soft texture fully.

Freezing

You can freeze homemade whoopie pies for longer storage without losing their amazing texture or flavor. Wrap each pie individually in plastic wrap, then place them in a freezer-safe bag or container for up to two months. When you’re ready to indulge, thaw them in the refrigerator overnight and bring to room temperature for best results.

Reheating

To refresh your stored whoopie pies, especially if refrigerated or frozen, let them sit at room temperature until softened. If you prefer a warm treat, pop them in the microwave for about 10 seconds—just enough to warm the filling without melting it completely. This simple step will bring back their fresh-baked magic.

FAQs

Can I use a different type of filling besides marshmallow fluff?

Absolutely! While marshmallow fluff is classic and adds that iconic soft sweetness, you can substitute with cream cheese frosting, peanut butter filling, or even chocolate ganache for a twist on the traditional whoopie pie.

Are these whoopie pies gluten-free?

This Homemade Chocolate Whoopie Pies with Marshmallow Fluff Filling Recipe uses all-purpose flour, so it’s not gluten-free as is. However, you can try a 1-to-1 gluten-free baking blend to make a gluten-free version, watching baking times closely to avoid over-baking.

How do I prevent the cookies from spreading too much?

Use a cookie scoop to portion out consistent dough balls and chill your dough slightly if it feels too warm before baking. Also, gently flattening the dough balls by hand rather than pressing too hard will help maintain the right size and thickness.

Can I make these whoopie pies ahead of time?

Yes! You can bake the cookies and prepare the marshmallow filling a day in advance. Keep the components separately covered and assemble just before serving to ensure the freshest texture.

What’s the best way to pipe the marshmallow filling?

A piping bag fitted with a large round tip is ideal for creating generous, even dollops that look beautiful and hold well between the cookies. If you don’t have a piping bag, a zip-top plastic bag with a small corner snipped off works surprisingly well too.
