How to Make Rainbow Whoopie Pies
-
Preheat your oven to 375°F (190°C) and line two baking trays with silicone mats. This ensures a perfect baking surface for your delightful treats.
-
Sift in a large bowl the all-purpose flour, baking powder, baking soda, and fine sea salt. This step helps aerate the dry ingredients for fluffy cookies.
-
Cream the softened unsalted butter in a separate mixing bowl on high speed until light and fluffy. Gradually add granulated sugar, followed by the egg and vanilla extract. Mix until everything is well combined and luscious.
-
Combine the dry ingredient mixture with the wet batter, followed by the whole milk. Mix until just combined to keep the cookies tender and soft.
-
Fold in the rainbow sprinkles gently until they are evenly distributed throughout the batter, creating that joyful color burst!
-
Pipe the batter into a piping bag fitted with a ½-inch round tip. On the prepared trays, pipe 1 – 1 ¼-inch rounds, leaving space for spreading. Pat the tops for a smooth surface.
-
Sprinkle additional rainbow sprinkles on top of the piped rounds for a festive touch. This will give your Whoopie Pies an extra pop of color.
-
Chill the trays in the refrigerator for 20 minutes to firm up the batter, ensuring they hold their shape while baking.
-
Bake for 8-9 minutes or until the edges are very lightly golden brown. Cool them on the trays for an easier transfer later.
-
Prepare the rainbow buttercream while the cakes cool down. Beat the softened unsalted butter until light and fluffy.
-
Gradually add confectioner’s sugar, alternating with the whole milk, until combined and creamy. The mixture should be rich and smooth.
-
Mix in the cake batter flavoring and kosher salt. Beat on high speed for 3-5 minutes until fully smooth and adjust consistency as needed.
-
Divide the buttercream into six bowls. Add 1-2 drops of gel food coloring to each bowl, creating vibrant reds, oranges, yellows, greens, blues, and purples.
-
Scoop each colored buttercream into its own piping bag. This will allow you to create beautiful swirls later!
-
Pipe a stripe of each color onto a piece of cling film to mimic a rainbow. Roll the cling film into a tube that will help create stunning patterns.
-
Trim the excess cling film from the ends and place the tube inside a larger piping bag fitted with a star tip. You’re all set to decorate!
-
Match the cooled cakes into pairs based on size to ensure even sandwiching when adding the frosting.
-
Pipe a swirl of the rainbow buttercream on the flat side of each bottom cake. Don’t hold back on that delicious frosting!
-
Top each with a second cake, creating a delightful sandwich that hides all that colorful buttercream inside.
-
Store the whoopie pies in an airtight container, layered between sheets of parchment, for up to five days. They’ll stay fresh and scrumptious!
Optional: Dust with additional rainbow sprinkles for that extra festive flair.

Rainbow Whoopie Pies Recipe FAQs
What should I look for when selecting ingredients for my Rainbow Whoopie Pies?
Absolutely! When choosing your ingredients, ensure your unsalted butter is soft but not melted, as this will help create that fluffy texture we love. For the flour, look for all-purpose flour without dark or brown spots—fresh is always best. Also, make sure your eggs are at room temperature for better emulsification, which contributes to a tender crumb.
How should I store my Rainbow Whoopie Pies?
The more, the merrier! Store your whoopie pies in an airtight container at room temperature for up to 5 days. Layer them carefully between sheets of parchment paper to avoid any sticky mishaps. This keeps the frosting intact and maintains that delightful soft texture of the cookies.
Can I freeze Rainbow Whoopie Pies, and how?
Certainly! To freeze, wrap each whoopie pie individually in plastic wrap and then place them in a freezer-safe bag or container. They can be frozen for up to 3 months. When you’re ready to indulge, simply thaw them in the fridge overnight or at room temperature for about 30 minutes. These little delights will be as good as fresh!
What should I do if my whoopie pies spread too much while baking?
Very! If your whoopie pies spread excessively, this could be due to a few reasons. Make sure your batter is chilled for the recommended 20 minutes before baking; this is crucial for maintaining shape. If you notice the dough is too soft, adding a little bit of extra flour—one tablespoon at a time—can help. Also, ensure that your oven is appropriately preheated to the correct temperature; an oven thermometer is a handy tool to keep on hand!
Are there any dietary considerations for Rainbow Whoopie Pies?
Yes! If you have allergies or dietary restrictions, consider using gluten-free all-purpose flour for a gluten-free version, which works quite well in this recipe. For a dairy-free option, you can substitute the butter with a vegan butter or coconut oil and opt for almond milk instead of whole milk. Always double-check your sprinkles and flavorings for any allergens—keep your baking worry-free and joyful!
