Ingredients
- Unsalted Butter: Unsalted butter, at room temperature, is the base of these cookies and adds flavor to every bite!
- Granulated Sugar: Granulated sugar adds sweetness and contributes to the chewy texture.
- Egg: An egg at room temperature adds to structure and creates some chewiness.
- Vanilla Extract: Pure vanilla extracts completes the flavor of the cookies.
- All Purpose Flour: Plain, all purpose flour creates soft and chewy cookies when measured properly. Read "Expert Tips" below for more information.
- Baking Powder: Baking powder helps with the texture and structure of the cookies. Do not substitute for baking soda.
- Salt: Salt brings out sweetness and enhances overall flavor!
- Food Coloring: What are rainbow sugar cookies without rainbow colors? I use red, orange, yellow, green, blue, and purple in this recipe. I highly recommend using food gel instead of liquid dye since you won't have to use as much dye to get a deep color.
Step-by-Step Process
STEP 1: Preheat your oven to 350 degrees Fahrenheit and then line baking sheets with parchment paper.
STEP 2: In a large bowl with a hand mixer or in the bowl of a stand mixer that is fitted with a paddle attachment, beat room temperature butter and granulated sugar together on medium speed until smooth.
STEP 3: Add the egg and vanilla extract to the batter and beat until fully combined throughout.


STEP 4: Pour the properly-measured all purpose flour, baking powder, and salt into the batter and mix only until you see the ingredients disappear.
STEP 5: Divide the dough into 6 equal parts and dye each a different color of the rainbow. You can mix the dye into each dough part one-by-one in the stand mixer.


STEP 6: Place the red dough ball on a sheet of parchment paper. Place another sheet of parchment paper over the dough ball and use a rolling pin or wine bottle to roll the dough into a thin slab. Then, repeat this process with each color, creating slabs that are close to size. They do not need to be exactly the same size.
STEP 7: Stack the colors- red, orange, yellow, green, blue, and purple on top. Then, take one shorter end of the stack and roll tightly. Use your fingers to shape any breakage of the dough.


STEP 8: Place the roll, uncovered, in the freezer for 10 minutes to firm up. Then, cut the roll into about ¼-inch cookies and use your hands to shape them if they have lost their circle shape.
STEP 9: Bake the cookies for 7-10 minutes until the edges are just barely starting to darken, the centers still look just slightly soft, and the tops are pale.

Frequently Asked Questions
No! If you want to skip out on the rainbow effect, you can simply roll the uncolored dough into the log, freeze it for 10 minutes, and slice them and bake them as directed!
I recommend placing the dough log, uncovered, in the freezer for 10 minutes to firm up. It makes cutting the cookies easier and ensures the swirl is in its best condition!

Expert Tips
Measuring Flour: You will end up with dry, tough cookies if you do not measure your flour correctly. Measure out 420g of flour exactly using a kitchen scale or simply use a spoon to carry flour into your measuring cups before using a knife to sweep the flour across the top in order to level the flour.
Food Dye: I highly recommend using food gel instead of liquid food coloring since you'll need to use much less dye to get deep colors. I used this starter set for years before upgrading to larger Americolor containers.

Make Ahead and Storing
You can make the dough ahead of time and chill it in the fridge for up to 2 days before adding the dye or after forming the roll. Just make sure to cover wrap it tightly. You can also slice the roll into cookies and freeze the unbaked cookie dough for up to 3 months.
After baking, store the cookies tightly covered, in an airtight container, or individually wrapped at room temperature for up to 4 days or in the freezer for up to 4 months.
