These vanilla whoopie pies are a joyful treat in every bite. Soft, tender vanilla cakes sandwich a rich vanilla-marshmallow filling for a dessert that feels special but is easy to make. They work equally well for family gatherings, bake sales, or an everyday sweet craving. With simple pantry ingredients and minimal equipment, these from-scratch whoopie pies are approachable and consistently delicious.
They’re quick to prepare, fun to assemble, and look impressive on a plate. After making them once, they often become a regular in my baking rotation because they require no special tools—just a few basics and a little time.

6 large cakes
Equipment
- Parchment paper
- Stand mixer or hand mixer
- Baking sheets (2 or more)
- Cooling rack
- Cake tester or toothpick
Ingredients
The Cakes
- ½ cup unsalted butter (1 stick), room temperature
- 1 cup granulated sugar
- 2 teaspoons vanilla extract
- 1 egg, room temperature
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon salt
- ¾ cup milk (whole preferred)
The Filling
- ¾ cup unsalted butter (1½ sticks), softened
- 1 cup powdered sugar, sifted
- 1 teaspoon vanilla extract
- ¼ teaspoon salt
- 2 cups marshmallow cream (for example, marshmallow fluff)
- ¼ teaspoon vanilla bean paste or scraped vanilla bean seeds (optional)
Instructions
Make the Cakes
- Prep the oven. Preheat to 350°F (175°C). Position oven racks in the upper-middle and lower-middle positions. Line two baking sheets with parchment paper.
- Cream the butter and sugar. In a stand mixer, beat the butter and granulated sugar on medium speed until light and fluffy, about 4–5 minutes. Scrape down the bowl as needed.
- Add the egg and vanilla. Beat in the egg and vanilla until combined, scraping the bowl to mix evenly.
- Combine the dry ingredients. In a separate bowl, whisk together the flour, baking soda, and salt.
- Alternate adding dry ingredients and milk. Reduce mixer speed to low. Add the dry ingredients to the butter mixture in three additions, alternating with the milk. Begin and end with the flour mixture. Mix until just combined.
- Scoop the batter. Use a ¼-cup measuring cup to portion batter onto the prepared sheets, spacing about 2 inches apart. For smaller cakes, use 2 tablespoons of batter for about 24 cakes.
- Bake. Bake large cakes 15–18 minutes (smaller cakes 10–13 minutes), rotating pans halfway through. Cakes are done when a toothpick comes out clean and the tops feel set. Cool completely on a rack before filling.
Make the Filling
- Beat butter and sugar. In a mixer, beat the softened butter and sifted powdered sugar on medium speed until light and fluffy, about 2–3 minutes.
- Add marshmallow cream and flavors. Add the salt, vanilla extract, and marshmallow cream. Beat until smooth and fully combined.
- Add vanilla bean. Mix in vanilla bean paste or scraped seeds on low speed until evenly distributed.
Assemble the Whoopie Pies
- Spread the filling. Spread about ⅓ cup of filling on the flat side of half the cakes. If filling is too soft, chill 10–15 minutes to firm it.
- Sandwich the cakes. Top each filled cake with a matching cake, pressing gently to spread the filling to the edges.
- Serve or store. Serve immediately or refrigerate up to 3 days. Bring to room temperature before serving for best texture.
Notes
Use room-temperature butter and egg so ingredients blend smoothly and produce a tender crumb. Cold ingredients can cause a lumpy batter.
If the filling feels runny, refrigerate briefly or add a tablespoon of powdered sugar at a time until it firms up.
Measure flour correctly by spooning it into the cup and leveling it off; scooping straight from the bag can pack in extra flour and dry the cakes.
Allow cakes to cool completely before assembling. Warm cakes will cause the filling to melt and become messy.
Sift powdered sugar before mixing into the butter to help prevent lumps and keep the filling fluffy. Use a piping bag or a plastic bag with the corner cut off for a neat, even application of filling.
Once you’ve mastered the classic version, try variations like adding a teaspoon of instant coffee to the filling for a mocha note, or a touch of almond extract in the cakes for a different flavor profile.

I absolutely love Vanilla Whoopie Pies. They strike the perfect balance of simplicity and comfort—soft cakes with a fluffy marshmallow filling. They bake quickly and can be adapted easily for different occasions, so they’re great for both weekday treats and weekend baking projects with kids.
Try variations by swapping the filling for buttercream, adding chocolate chips to the batter, or flavoring the filling with coffee or fruit extracts. These small changes keep the process interesting while using the same basic steps and ingredients.
Key Ingredients and Tools
Having the right ingredients and tools helps ensure success. Below are items that make this recipe straightforward and reliable.
- Vanilla bean paste: Adds intense vanilla flavor and visible specks. If unavailable, increase vanilla extract slightly.
- Marshmallow cream (fluff): Gives the filling its classic texture. It’s convenient and consistent for this recipe.
- Whole milk: Helps deliver a richer cake; other milks will work but may alter texture slightly.
- Parchment paper: Prevents sticking and makes removal easier for these delicate cakes.
- Stand mixer: Speeds mixing but a hand mixer works fine; just beat until the proper texture is reached.
- Unsalted butter: Allows better control of salt level; salted butter will change the balance slightly.
Tips for the Best Vanilla Whoopie Pies
- Mix wet and dry ingredients until combined—overmixing can make cakes tough.
- Chill the batter for 10–15 minutes if it seems too loose to help the cakes hold shape while baking.
- Use a scoop for uniform cakes so they bake evenly and pair nicely.
- On humid days, the filling may be softer—chill assembled pies briefly to firm the filling.
- If transporting the pies, chill for 30 minutes after assembling to stabilize the filling.
Serving Suggestions
Serve whoopie pies with fresh berries, a scoop of vanilla ice cream, a cup of coffee or tea, or a dollop of lightly whipped cream.
Storage Instructions
Store assembled whoopie pies in an airtight container in the refrigerator for up to 3 days. Let them sit at room temperature 10–15 minutes before serving. For longer storage, wrap each pie individually and freeze up to 2 months; thaw in the refrigerator overnight.
Troubleshooting and Help
Chill the filling for 10–15 minutes to firm it. If still soft, add powdered sugar one tablespoon at a time until it reaches the desired consistency.
Yes. A simple buttercream works well as an alternative if you prefer a less marshmallow-forward filling.
If butter was too soft or batter wasn’t chilled, cakes can spread. Try chilling the batter for 10–15 minutes before scooping and baking.
Parchment prevents sticking and protects the delicate cake bottoms during removal, keeping the cakes intact.
Yes. Use a tablespoon or small cookie scoop and reduce baking time—start checking around 10 minutes to prevent overbaking.
You can bake the cakes ahead and store them airtight for up to 2 days. Fill shortly before serving or assemble and refrigerate for up to 3 days.
Absolutely. Try chocolate ganache, peanut butter frosting, or fruit-forward fillings to customize the treat.
Vanilla Whoopie Pies are an easy, satisfying homemade dessert. Their soft cakes and creamy filling make them an ideal treat to bake for friends, family, or whenever you want something sweet and comforting.
