Whoopie pies are the perfect balance of cake and cookie, with soft, pillowy layers of sweet baked goodness sandwiched between a rich, creamy filling. Originating from the northeastern United States, these treats have quickly become a favorite in households and bakeries alike. Whether you’re looking to enjoy a homemade dessert with your family or impress guests at your next gathering, the whoopie pie is a timeless classic that can be customized in endless ways. This comprehensive guide will take you through the history of the whoopie pie, offer a list of essential ingredients, and provide a detailed step-by-step recipe to create the perfect whoopie pies at home.
A Brief History of Whoopie Pies
Whoopie pies are often considered a regional specialty, most commonly associated with the Pennsylvania Amish and the New England region. While there is no definitive record of their invention, several theories exist as to the origins of these beloved treats.
One of the most popular theories is that whoopie pies were first made by Amish women, who would bake these sweet treats as a special snack for their husbands. When the men would open their lunchboxes to find these delightful desserts, they would reportedly exclaim, “Whoopie!”—thus giving the treat its name. Another theory suggests that whoopie pies have their roots in the American colonial period, when the combination of cakes and filling was a popular method of baking.
Regardless of their exact origins, whoopie pies gained significant popularity in the 20th century, particularly in the northeastern U.S. Today, whoopie pies are sold in bakeries and grocery stores across the country, but many home bakers prefer to create them from scratch for a truly authentic taste.
Why Make Homemade Whoopie Pies?
Making whoopie pies from scratch offers several advantages:
- Customizable Flavors: When you make whoopie pies at home, you have full control over the flavors of both the cake layers and the filling. You can add ingredients like cocoa powder, vanilla, or even pumpkin to the cake, and experiment with different types of fillings, from classic buttercream to cream cheese or marshmallow.
- Freshness: Homemade whoopie pies are always fresher than store-bought versions, ensuring the most delicious bite. With each batch, you’ll enjoy the perfect combination of soft, moist cake and creamy filling.
- Personal Touch: Nothing beats the satisfaction of baking a batch of whoopie pies from scratch and sharing them with loved ones. It’s a great way to bond with friends and family and create lasting memories while enjoying a sweet treat.
Whoopie Pie Ingredients
To make the perfect whoopie pies, you’ll need to gather the following ingredients. We’ll break them down into two categories: the cake layers and the filling.
For the Cake Layers:
- All-purpose flour – 2 1/2 cups. This is the base of the cake and provides structure.
- Cocoa powder – 1/2 cup. This gives the whoopie pies their rich, chocolate flavor. Use unsweetened cocoa powder for the best results.
- Baking soda – 1 teaspoon. This helps the cakes rise and become light and fluffy.
- Baking powder – 1 teaspoon. Works alongside baking soda to provide lift.
- Salt – 1/2 teaspoon. Enhances the flavor of the cake.
- Unsalted butter – 1/2 cup (1 stick), softened. The butter adds richness and tenderness to the cake.
- Granulated sugar – 1 cup. Provides sweetness and moisture to the cake layers.
- Eggs – 2 large eggs. Bind the ingredients together and help with the texture of the cake.
- Buttermilk – 1 cup. Buttermilk provides moisture and creates a tender, soft texture.
- Vanilla extract – 1 teaspoon. Adds depth of flavor to the cake.
For the Filling:
- Unsalted butter – 1/2 cup (1 stick), softened. The butter provides a creamy texture and rich flavor.
- Vegetable shortening – 1/2 cup. This gives the filling a smooth consistency that holds up well in the pie.
- Powdered sugar – 4 cups. The powdered sugar helps sweeten and thicken the filling.
- Marshmallow fluff – 1 cup. Adds that signature light and airy texture to the filling.
- Vanilla extract – 1 teaspoon. Enhances the flavor of the filling.
Step-by-Step Instructions for Making Whoopie Pies
Making whoopie pies from scratch is simple, but the results are spectacular. Follow these detailed instructions for the best whoopie pies you’ve ever had.
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). Make sure the oven is fully preheated before you begin baking your cake layers.
Step 2: Prepare the Baking Sheets
Line two baking sheets with parchment paper or silicone baking mats to prevent the cakes from sticking. This ensures easy removal after baking and helps the whoopie pies hold their shape.
Step 3: Mix the Dry Ingredients for the Cake Layers
In a large bowl, sift together the following dry ingredients:
- All-purpose flour
- Cocoa powder
- Baking soda
- Baking powder
- Salt
Whisk these dry ingredients together until they are well combined. Sifting the flour and cocoa powder ensures a smooth batter with no lumps.
Step 4: Cream the Butter and Sugar
In a separate large bowl, use a hand mixer or stand mixer to beat the softened butter and granulated sugar together on medium speed until light and fluffy. This step is crucial for creating a tender and airy cake. It should take about 3-4 minutes to achieve the right consistency.
Step 5: Add the Eggs and Vanilla
Add the eggs, one at a time, beating well after each addition. Then, add the vanilla extract and mix until combined. The mixture should be smooth and slightly fluffy.
Step 6: Alternate Adding Dry Ingredients and Buttermilk
Now, alternate adding the dry ingredients and the buttermilk to the butter mixture, starting and ending with the dry ingredients. Begin by adding about one-third of the dry ingredients to the butter mixture, then mix until combined. Add half of the buttermilk and mix. Continue alternating until all the dry ingredients and buttermilk are fully incorporated into the batter. Be careful not to overmix, as this can result in dense cake layers.
Step 7: Scoop the Batter onto the Baking Sheets
Using a cookie scoop or two tablespoons, drop the batter onto the prepared baking sheets. Space the mounds of batter about 2 inches apart. You want each whoopie pie to be roughly the same size to ensure even baking.
Step 8: Bake the Cake Layers
Bake the cake layers in the preheated oven for 10-12 minutes or until a toothpick inserted into the center of the cakes comes out clean. Be careful not to overbake; you want the cakes to be soft and moist, not dry.
Step 9: Cool the Cake Layers
Once the cakes are done, remove them from the oven and allow them to cool on the baking sheets for about 5 minutes. Then, transfer the cakes to a wire rack to cool completely.
Step 10: Make the Filling
While the cake layers are cooling, prepare the filling. In a large bowl, beat together the softened butter, vegetable shortening, and powdered sugar until smooth and fluffy. This may take about 3-4 minutes.
Once the butter and shortening are well blended, add the marshmallow fluff and vanilla extract. Beat until the filling is smooth and creamy. If the filling seems too thick, add a tablespoon of milk or water at a time until you reach the desired consistency.
Step 11: Assemble the Whoopie Pies
Once the cakes have cooled completely, it’s time to assemble the whoopie pies. Flip half of the cake layers upside down, so the flat side is facing up. Using a spoon or a piping bag, generously spread or pipe the marshmallow filling onto the flat side of each cake. Top with the remaining cake layers, flat side down, to form sandwiches.
Press gently to ensure the filling spreads evenly to the edges.
Step 12: Serve and Enjoy
Once the whoopie pies are assembled, they are ready to be enjoyed! These treats are best served fresh, but they can also be stored in an airtight container at room temperature for up to 3 days. If you want to store them for longer, refrigerate them for up to a week.
Tips for the Perfect Whoopie Pie
- Flavor Variations: Feel free to add your own twist to the flavor of the cakes. Try adding a pinch of cinnamon, nutmeg, or even a bit of espresso powder for a richer taste.
- Filling Variations: You can experiment with different fillings such as cream cheese frosting, peanut butter, or chocolate ganache. Marshmallow fluff is traditional, but the possibilities are endless.
- Storage: Store the whoopie pies in an airtight container to keep them fresh. If you plan to freeze them, wrap each whoopie pie in plastic wrap and store them in a freezer-safe bag for up to 3 months.
