Rainbow Butter Cookies Ingredients
For the Dough
Unsalted Butter - Provides richness and tenderness; use salted butter while omitting added salt if preferred.
Sugar - Adds sweetness and acts as a tenderizer for the dough.
Large Egg - Binds ingredients and contributes to the cookie’s chewy texture; make sure it's at room temperature.
All-Purpose Flour - Gives structure to the cookies; for best accuracy, use the spoon and level method when measuring.
Milk - Adds moisture to the dough; whole milk is best, but 2% or low-fat can work as substitutions.
Vanilla Extract - Enhances flavor delightfully; you can substitute with only ½ teaspoon of almond or lemon extract if needed.
Fine Sea Salt - Balances the sweetness; you can omit this if using salted butter.
For the Color
Food Coloring - Creates vibrant rainbow layers; red, yellow, and blue can be blended for other colors.
Rainbow Sprinkles - Envelops the cookies for a fun texture; opt for high-quality sprinkles for the best results.
These Rainbow Butter Cookies are not just delicious; their colorful presentation makes them perfect for any gathering!
How to Make Rainbow Butter Cookies
Prep Dough: Start by creaming together the unsalted butter, sugar, and vanilla extract in a stand mixer until the mixture is light and fluffy-this will take about 3-5 minutes. Add the room temperature egg and mix until fully incorporated.
Form Dry Mix: Gradually mix in the flour and fine sea salt. Blend on low until the mixture becomes crumbly. Add 1-2 tablespoons of milk, mixing until a cohesive dough forms that holds together nicely.
Color Dough: Divide the dough into portions, depending on how many colors you'd like. Add food coloring to each portion, kneading until the color is uniformly distributed and vibrant. Roll each colored dough into cylinders.
Combine Dough: Flatten a piece of uncolored dough. Layer the colored cylinders on top, then fold the uncolored dough over them. Roll the layered dough into a ball, ensuring the colors are mixed but still visible.
Coat and Bake: Roll the dough ball in rainbow sprinkles, then place it on a lined baking sheet, spacing them about 3 inches apart. Bake in a preheated oven at 375°F for 15 minutes or until the edges are faintly golden.
Cool: Once baked, carefully transfer the cookies to a wire rack to cool completely, letting their flavors meld together beautifully.
Optional: Drizzle with melted chocolate for an extra touch of sweetness.

How to Store and Freeze Rainbow Butter Cookies
Airtight Container: Store cookies in an airtight container at room temperature for up to 1 week to maintain their soft and buttery texture.

Make Ahead Options
These Rainbow Butter Cookies are perfect for meal prep enthusiasts! You can prepare the cookie dough up to 24 hours in advance by mixing the ingredients and placing the dough in an airtight container in the refrigerator. This method not only saves time but also enhances the flavors as they meld overnight. If you want to extend your prep even further, you can freeze the unbaked cookie dough for up to 3 months-just thaw in the refrigerator overnight before rolling in sprinkles and baking. When you’re ready to bake, simply slice the dough, coat with sprinkles, and pop it in the oven for a quick, colorful treat that's just as delightful as if freshly made!
