Easy Whoopie Pies from a Cake Mix
These whoopie pies can be made with a basic chocolate cake mix! I have filling recipes for vanilla whoopie pies and peanut butter whoopie pies. The best part is, you don't need any special tools or pans to make these!
Ingredients
For Whoopie Pie Rounds
- 1 chocolate cake box mix I used Duncan Hines Devil's Food
- 2 eggs
- 1/2 cup oil I used vegetable
- 1 cup coffee Replace the water your cake mix calls for with coffee
- 1 tsp vanilla
For Vanilla Filling (Double if you want all vanilla whoopie pies)
- 1/2 cup butter softened
- 2 cups powdered sugar
- 1 tsp vanilla
- 2-3 Tbsp heavy whipping cream
For Peanut Butter Filling (Double if you want all peanut butter whoopie pies)
- 1/4 cup butter softened
- 1/4 cup peanut butter
- 2 cups powdered sugar
- 2-3 Tbsp heavy whipping cream
Instructions
To Make Whoopie Pie Rounds
- Preheat oven to whatever temperature is specified on your boxed cake mix. Line some cookie sheets with parchment paper.
- Mix cake mix, eggs, oil, coffee and vanilla together until smooth.
- Using a cookie scoop (or an ice cream scoop), place round dollops on a cookie sheet lined with parchment paper. Leave plenty of space between them so they can expand. I fit only 6 per cookie sheet with the size of my scoops.
- Bake your whoopie pie rounds for 8-10 minutes, or until a toothpick inserted comes out clean and your round is firm in the middle.
- Allow your whoopie pie rounds to cool completely before adding the filling.
To Make Filling
- Decide whether you want vanilla filling, peanut butter filling, or both. If you want just one flavor of filling, double the measurements from above to fill all of your whoopie pie rounds. If you want both flavors, make one batch of each filling in separate bowls.
- Place all of your filling ingredients together in a mixing bowl. Start with just 2 tablespoons of heavy whipping cream. Beat all of the ingredients together until smooth. If the mixture seems too thick, add an extra tablespoon of heavy whipping cream.
- Place one of your whoopie pie rounds with the flat side up (This will be the bottom of the whoopie pie sandwich). Place filling on this side. I like to put my filling in a piping bag with a Wilton 1M tip and pipe a pretty swirl in the middle. Then, place another round on top to make your whoopie pie sandwich.
- Repeat this process until all of your whoopie pies are filled.
- I recommend storing the whoopie pies in a container lined with parchment paper and sprinkled with powdered sugar, as they get a little sticky.
