Cake Mix Whoopie Pies have soft, pillowy cookies surrounding a smooth and creamy buttercream. They're perfect for birthday parties, bake sales and everyday baking!Jump to Recipe
If a cake and a cookie had a baby, I'm pretty sure a whoopie pie would be the end result. Ok, maybe that's a strange way to think about it! But either way, the smooth filling with the moist and soft cookies surrounding it is just heavenly!
Never made a whoopie pie? Do they seem intimidating? They really shouldn't be. Don't let that intimidation stand between you and a whoopie pie!! Trust me....these things are SO good and surprisingly quite simple!
Why are they called "Whoopie Pies?"
Great question!! Lancaster county legend has it that the Amish started this tradition when they had leftover cake batter. They'd bake the batter into cookies and turn them into these treat. The kids and husbands of these Amish women would explain "whoopie!" when they saw one of these in their lunchbox, so they came to be known as Whoopie Pies!
What do you need to make these easy Whoopie Pies?
Before we get into which ingredients you need, it's super important that you have parchment paper or silicone baking mats. They're essential in making sure your cookies can be easily removed from the pan.
Ok, now for the ingredients!!
- Cake Mix - See below for different flavors you can use!
- Pudding Mix - Again, see below for different flavors you can use! No matter which flavor you go with, make sure it's the instant pudding mix.
- Vegetable Oil
- Eggs - I used large eggs.
- Butter - I use salted butter. If you only have unsalted butter, you can use that plus ¼ teaspoon salt. You'll want to make sure it's softened a bit.
- Powdered Sugar
- Vanilla Extract
- Marshmallow Cream - You will find this near the marshmallows in the grocery store. Depending on the brand, it might be called Marshmallow Fluff.
How to Make Whoopie Pies
Make the Cookies
Start by lining a few cookie sheets with parchment paper or silicone baking mats and preheat the oven to 350F. Add the dry cake mix, pudding mix, water, eggs and oil to a large bowl. You can mix by hand, use an electric mixer or a stand mixer fitted with the whisk attachment. Mix on low speed until combined then stop the mixer and scrap down the sides of the bowl with a rubber spatula.
Beat the batter on medium speed for 2 minutes. Drop batter onto the lined baking sheets using a medium cookie scoop, making sure to give each of them room to puff up as they bake. Bake the cake-like cookies until they no longer look wet on top (they should be shiny, but not wet to the touch). Let them cool for a couple minutes before removing to a cooling rack.
Make the Creamy Filling
In a separate bowl, add the softened butter. I find it easiest to make the filling using an electric hand mixer or a stand mixer fitted with the paddle attachment. Give the butter a stir until smooth then add the powdered sugar and vanilla. It'll be quite thick at this point.
Next, add the marshmallow fluff and stir until combined.
Assemble the Whoopie Pies
Once the cookies are completely cool and the filling is done, it's time to put these delicious whoopie pies together!! I like to match up cookies that are the same size and set them next to each other.
Use a spoon, a piping bag with a large round tip or a small cookie scoop to add the marshmallow creme filling to the bottom of one of the cookies. Use the second cookie to create a sandwich and repeat with the remaining cookies.
What kind of cake mix should I use?
Here's what I love about these whoopie pies - you can use about ANY cake mix and pudding mix flavor! Chocolate whoopie pies are simply a classic and funfetti is such a fun one for birthdays and celebrations! And though traditional whoopie pies have a marshmallow filling, feel free to use flavored buttercream instead!
Here are some delicious options:
- Classic Chocolate Whoopie Pies: Devils Food Cake Mix + Chocolate Pudding Mix
- Vanilla Whoopie Pies: Vanilla/White/Yellow Cake Mix + Vanilla (or French Vanilla) Pudding Mix
- Red Velvet Whoopie Pies: Red Velvet Cake Mix + Chocolate Pudding Mix (Can use Cream Cheese Filling rather than marshmallow creme frosting for a more classic red velvet flavor)
- Birthday Cake Whoopie Pies: Funfetti Cake Mix + Vanilla (or French Vanilla) Pudding Mix
- Lemon Whoopie Pies: Lemon Cake Mix + Lemon Pudding Mix
- Spiced Whoopie Pies: Spice Cake Mix + Vanilla (or French Vanilla) Pudding Mix
- Strawberry Whoopie Pies: Strawberry Cake Mix + Strawberry Cream (or Vanilla) Pudding Mix
How should I serve Whoopie Pies?
You can serve these cold (right out of the fridge) or after setting out a room temperature for 15 minutes. I personally prefer them right out of the fridge.
These can be a little messy to eat, so I like serving them on a flattened cupcake wrapper!
How should I store Whoopie Pies?
These need to be stored in the fridge - they'll last longer that way too. If you want to freeze them, you certainly can! Just be sure to put them in an airtight container in a single layer OR with waxed/parchment paper between layers so they don't stick together.
