How to Make Rainbow Cookie Sandwiches
-
Cream Together: In a mixing bowl, blend the softened unsalted butter and confectioner’s sugar until the mixture is smooth and fluffy. This will create the perfect base for your cookies that melts in your mouth!
-
Mix in Wet Ingredients: Add the vanilla extract, milk, and a pinch of kosher salt to the creamed mixture. Stir well until everything is combined and the dough reaches a soft, workable texture.
-
Divide and Color: Gently divide the dough into separate portions for your gel food coloring. Add the colors one by one, mixing each portion thoroughly until you achieve the vibrant hues you desire.
-
Chill the Dough: Wrap each colored dough ball in plastic wrap and refrigerate for about 30 minutes. This helps the dough firm up, making it easier to roll out later.
-
Roll and Cut: Preheat your oven to 350°F. Roll out each colored dough on a lightly floured surface to about 1/4 inch thick. Use fun cookie cutters to create shapes, and place them on a baking sheet lined with parchment paper.
-
Bake: Place the baking sheet in the oven, and bake for about 10-12 minutes, or until the edges are lightly golden. Let them cool completely on a wire rack before assembling.
-
Assemble Sandwiches: Take one cookie and spread your favorite filling—such as icing or frosting— onto the bottom side. Top it with another cookie to create a delightful sandwich.
Optional: Sprinkle some edible glitter for an extra magical touch!

Expert Tips for Rainbow Cookie Sandwiches
-
Chilling is Key: Don’t skip the chilling step! This helps the dough firm up for easier rolling and keeps the cookies from spreading too much while baking.
-
Color Caution: When using gel food coloring, start with a small amount and gradually add more until you reach your desired vibrancy. It’s easy to overdo it!
-
Even Baking: Rotate your baking sheet halfway through the baking time for even browning. This ensures all your cookies come out perfectly golden.
-
Filling Fun: Experiment with different fillings! From buttercream to jam, choosing a filling that complements your rainbow cookies can elevate their flavor.
-
Storage Tips: Store your Rainbow Cookie Sandwiches in an airtight container at room temperature for the best taste and texture. Enjoy within a few days for maximum freshness!
How to Store and Freeze Rainbow Cookie Sandwiches
Room Temperature: Keep your Rainbow Cookie Sandwiches in an airtight container at room temperature for up to 3 days to maintain their delightful freshness and texture.
Fridge: If you want them to last a bit longer, refrigerate the sandwiches for up to a week in an airtight container. Just note that chilling may alter the texture slightly.

Rainbow Cookie Sandwiches Recipe FAQs
How do I choose ripe ingredients for this recipe?
Absolutely! When selecting your ingredients, make sure your unsalted butter is at room temperature—soft enough to easily cream but not melted. For the gel food coloring, choose high-quality brands like AmeriColor or Wilton for the brightest hues and consistency.
How should I store leftover Rainbow Cookie Sandwiches?
To maintain their freshness, store your Rainbow Cookie Sandwiches in an airtight container at room temperature for up to 3 days. If desired, you can refrigerate them for a week, but remember that chilling might soften the cookie texture slightly.
Can I freeze Rainbow Cookie Sandwiches?
Yes, indeed! For longer storage, wrap your unfilled Rainbow Cookie Sandwiches tightly in plastic wrap, then place them in a freezer-safe bag or container. They can last up to 3 months in the freezer. When ready to indulge, allow them to thaw at room temperature, or warm them in the microwave for 10-15 seconds for a freshly-baked experience!
What should I do if my dough is too sticky or too dry?
Very common! If your rainbow cookie dough is sticky, add a little bit of flour—about a tablespoon at a time—while mixing to reach the right consistency. On the flip side, if it feels too dry and crumbly, add additional milk, a teaspoon at a time, until it becomes smooth and pliable for rolling.
Are there any dietary considerations for these cookies?
Definitely! If anyone has allergies, be mindful of the ingredients. The butter and milk can be substituted with vegan versions for dairy-free cookies. You can use plant-based butters and non-dairy milk like almond milk or oat milk. Always check food coloring labels for any potential allergens, especially for those with sensitivities to food dyes.
What if I can’t find gel food coloring?
Don’t worry! If gel food coloring is unavailable, you can use liquid food coloring, but be aware that it might dilute the dough. Start with just a few drops and adjust accordingly to achieve vibrant colors without compromising the dough’s consistency. Alternatively, consider natural colorants like beet juice for red or turmeric for yellow for a more organic approach!
