This Easy Whoopie Pies recipe is perfect for Valentine's Day. Or any day you want to make something special for your sweetie pie.
It’s super easy to make because these are gluten free cake mix whoopie pies made in a non-stick whoopie pie pan.
This recipe also includes how to create a decadent, ooey gooey whoopie pie filling that’s also gluten and dairy free - and delicious!
What the heck is a whoopie pie?
First, when I found the heart shaped whoopie pie pan, I had to do a little research on creating gluten free whoopie pies.
UPDATE: Unfortunately, heart shaped whoopie pie pans are no longer made. You may be able to find used heart shaped ones on eBay or in thrift stores.
Believe it or not, I don’t think I’ve ever eaten a whoopie pie. For some reason, I was under the impression it was like a Moon Pie.
Wrong! Whoopie pies are basically a cupcake in sandwich cookie form with a gooey layer of marshmallow cream in the middle. Swoooooon, right?
I’ve even seen a vanilla whoopie pie recipe, but there are no hard and fast rules when it comes to flavors.
The origin of the whoopie pie is contested as Maine, Massachusetts, New Hampshire, and Pennsylvania all claim to be the birthplace. According to Wikipedia:
Labadie's bakery in Lewiston, Maine has been making the confection since 1925. The now-defunct Berwick Cake Company of Roxbury, Massachusetts was selling "Whoopee Pies" as early as the 1920s, but officially branded the Whoopee Pie in 1928 to great success.
Various claims suggest that the whoopie pie originated in Massachusetts and spread both north and south, or that German immigrants in Pennsylvania brought the predecessor of the Whoopie Pie to communities throughout the northeast.
Naturally, the whoopie pie recipe used Marshmallow Fluff in the filling!
Can you make an easy whoopie pie recipe that’s also gluten free?
I'd only baked gluten free cupcakes from mixes. Since I wanted to create a gluten free whoopie pie recipe, I did some research on making gluten free cupcakes from scratch.
Let me tell you folks, baking gluten free from scratch is a lot of work. Plus, I didn’t want you folks to go out and buy two or three different kinds of flours, a binder like guar gum, and experiment with adding cocoa powder to all that, too.
Plus, there was the matter of making homemade frosting.
Us busy folks ain’t got time for that! Obviously, there must be a better way.
For these fun desserts, I decided to swirl the yellow and chocolate gluten free cake mix together for a cool effect.
In addition, I’d make red or pink gluten free whoopie pie filling. Fun, fun, fun!
Tips for swirling the whoopie pie batter
Don’t worry about your results. Worse comes to worse, you’ve completely mixed the two batters. However, your whoopie pie will still look and taste great after baking!
If you find swirling too hard after a few tries, make half the easy gluten free whoopie pies with yellow cake mix and half with the gluten free chocolate cake mix.
Then make chocolate whoopie pies and vanilla whoopie pies with whatever flavor frosting you picked in the middle. It’ll still be a cute Valentine’s Day treat for your special gluten free sweeties!
How to make whoopie pies gluten free and dairy free
My other challenge was not only make the whoopie pies gluten free but dairy free, too.
I also like both the Betty Crocker frostings and cake mixes since you can easily find it at your local grocery store and don’t have to go to a specialty health food store or order it online.
But if you have another favorite gluten free cake mix, go ahead and use it.
To keep the whoopie pie recipe dairy free, I used a vegan butter spread and unsweetened coconut milk. If you aren’t dairy free, you can use regular butter and milk.
Whoopie pie filling tips
Betty Crocker frostings are clearly labeled as gluten free foods. They’re also dairy free. But always check the labels every time you purchase your supplies since ingredients can change.
For this post, I chose Funfetti Red Radiant Vanilla and Strawberry Marshmallow Betty Crocker frostings that I found at Walmart.
I believe both are special seasonal flavors and neither contain any dairy products per their labels. (The recipe below uses two flavors to reflect what’s shown in the pictures.)
Of course, you can choose any gluten free Betty Crocker frostings that appeal to you based on what you can find at your store or online.
If you want to be frugal, one can of frosting and half of the container of Marshmallow Fluff should be enough. (There was enough leftover frosting to make another batch of whoopie pies.)
Since I made this, Marshmallow Fluff brand has come out with a strawberry flavor.
Not only would this be kind of yummy, the color would be very pretty for Valentine’s Day, too!
Whoopie pies are not just for Valentine’s Day
Now I know you must be thinking that buying a whoopie pie baking pan for one holiday is a bit silly. Well, you can use the whoopie pie pan to make cookies, too.
Other whoopie pie ideas are using yellow cake mix and green frosting for St. Patrick’s Day or maybe some red, white and blue frosting for Fourth of July.
There are birthdays, baby showers, engagement parties, bridal showers, and class parties to bake whoopie pies for, too.
I’ve used Wilton colors for years and love how well they work for all my baking needs.
I also just bought a box of Pillsbury Funfetti Gluten Free Cake and Cupcake Mix, so the ideas for easy gluten free whoopie pies are endless!
You’ll thank me when you are baking one dozen, while another dozen cool.
Easy Whoopie Pies Recipe
For gluten free chocolate cake batter:
- 1 box Betty Crocker Gluten Free Devil's Food Cake Mix
- 6 tablespoons dairy free or vegan buttery spread, softened
- 2 eggs
- 5 ounces coconut milk
For gluten free vanilla cake batter:
- 1 box Betty Crocker Gluten Free Yellow Cake Mix
- 6 tablespoons dairy free or vegan buttery spread
- 2 eggs
- 5 ounces coconut milk
For the whoopie pie filling:
- 2 cans Betty Crocker gluten free frostings, flavors of choice
- 1 (7 1/2 ounce) container marshmallow fluff, divided
For the whoopie pies:
- Preheat oven to 350 degrees F.
- Place the devil’s food cake mix, buttery spread, eggs, and coconut milk into the bowl of your stand mixer. Mix on low until the ingredients are incorporated. Then mix on high for one minute. Scrape down the sides of the bowl with a spatula. Then mix on high for one minute more.
- Pour the mix into a medium mixing bowl.
- Repeat with the yellow cake mix but leave the batter in the stand mixer bowl.
- Using a small batter spoon, scoop 2 tablespoons worth of one flavor of batter into each pan cavity. Then spoon 1 teaspoon of the other batter flavor into each cavity.
- Use a toothpick to swirl the batter flavors together and spread the batter evenly to the edges of the pan cavity. The cavity should be 2/3 full.
- Place the pan in the oven and bake for 8-10 minutes or until the top of the whoopie cake springs back when touched.
- Remove pan from oven and allow whoopie cakes to cool for 8 minutes before removing from pan.
- Wash and dry pan thoroughly. Repeat steps 5-8 (switching batter as “base flavor”) until all batter is used up.
For the whoopie pie filling:
- As the last cakes are baking, wash and completely dry the mixer bowl.
- Empty one can of frosting into the mixer bowl. Add 1/2 of the marshmallow fluff. Whip contents on high until the filling is fluffy and the color is fully mixed.
- Scoop frosting out into a mixing bowl.
- Wash and complete dry the mixer bowl. Repeat step 2 with second flavor of frosting and remaining marshmallow fluff. Leaving filling in mixer bowl.
For assembling the easy whoopie pies:
- Using an offset icing spatula, gently spread a generous dollop of filling on the flat side of one cookie. (If you spread the filling around too much, as you would with cake frosting, it’ll just pick up crumbs and start looking messy.)
- Place the flat side of a second cookie on the filling. Keep the whoopie pies as flat as possible even though the tops may be slightly uneven. If you stack them on their sides or at an angle, the top cookie may slide off.
- Serve them up! Easy Whoopie Pies are best eaten within a day or two. After that, they will get a bit stale.
- Serving size: 1 whoopie pie
