Ingredients
For the Chocolate Cookies
• 1 box chocolate cake mix
• 2 large eggs
• ½ cup vegetable oil
For the Vanilla Filling
• ½ cup unsalted butter, softened
• 1 ½ cups powdered sugar
• 1 teaspoon vanilla flavoring extract
• 1-2 tablespoons milk
How to Make Chocolate Cake Mix Whoopie Pies
1. Preheat the Oven
Preheat your oven to 175°C (350°F) and line a baking sheet with parchment paper.
2. Make the Batter
In a large mixing bowl, combine the chocolate cake mix, eggs, and vegetable oil. Mix until a thick and smooth batter forms.
The batter should be soft and scoopable.
3. Scoop the Cookies
Using a cookie scoop or tablespoon, drop small rounds of batter onto the prepared baking sheet. Leave enough space between each scoop since the cookies will spread slightly.
4. Bake
Bake for 8-10 minutes, or until the tops are set and the edges look slightly firm.
Remove from the oven and allow the cookies to cool completely before filling.
5. Prepare the Filling
In a mixing bowl, beat the butter until smooth. Add powdered sugar, vanilla flavoring extract, and milk, then mix until the frosting becomes light and fluffy.
6. Assemble the Whoopie Pies
Spread or pipe the filling onto the flat side of one cookie. Place another cookie on top and gently press together to form a sandwich.
Repeat with the remaining cookies.
Tips for Perfect Whoopie Pies
• Use a cookie scoop
This ensures evenly sized cookies so the whoopie pies match perfectly.
• Do not overbake
Slightly soft cookies create the classic tender texture.
• Let cookies cool completely
Warm cookies will melt the filling.
• Chill before serving
Refrigerate the assembled whoopie pies for 20 minutes to help the filling set.
Flavor Variations
You can easily customize these chocolate whoopie pies.
• Chocolate Marshmallow Whoopie Pies
Use marshmallow fluff frosting instead of buttercream.
• Double Chocolate Whoopie Pies
Add mini chocolate chips to the batter.
• Chocolate Peanut Butter Whoopie Pies
Fill with peanut butter frosting for a rich flavor combination.
How to Store Chocolate Whoopie Pies
Store the assembled whoopie pies in an airtight container.
• Room temperature: up to 2 days
• Refrigerator: up to 5 days
• Freezer: up to 2 months
