The Inspiration Behind Rainbow Cookies
Though the name “rainbow cookies” might make you think of Italian-style layered cookies, these cookies are quite different. The traditional Italian rainbow cookies are made from almond cake with layers of raspberry preserves or apricot jam and covered in chocolate. In contrast, these Rainbow Chocolate Chip Cookies are a soft, chewy treat with colorful dough mixed with plenty of chocolate chips—a fun twist on the classic chocolate chip cookie!
Ingredients You’ll Need
To create these vibrant Rainbow Chocolate Chip Cookies, you’ll need the following ingredients:
- 2 1/2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup butter (room temperature)
- 1/2 cup brown sugar
- 1/2 cup granulated sugar
- 1 large egg + 1 egg yolk (for extra thickness)
- 2 teaspoons vanilla extract
- 1 cup white chocolate or semisweet chocolate chips (or both)
- 3–8 colors of food coloring or gel food colors

How to Make Rainbow Chocolate Chip Cookies
These cookies are easy to make with a few simple steps. Here’s how to do it:
Step 1: Prepare the Cookie Dough
- Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or spray with non-stick cooking spray.
- In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
- In a large bowl, beat the butter and sugars together using a hand mixer or stand mixer on medium-high speed until smooth and creamy.
- Add the egg, egg yolk, and vanilla extract, and mix on low speed until combined.
- Gradually add the dry ingredients to the wet mixture and mix until just combined. This will be your base dough.
Step 2: Add the Food Coloring
- Divide the dough into 3 to 8 portions, depending on how many colors you want in your rainbow cookies.
- Add food gel colors to each portion of dough. Use as much or as little as you like to achieve vibrant or pastel shades of the rainbow (red, orange, yellow, green, blue, indigo, and violet).
- Mix the food coloring thoroughly into each portion of dough until the colors are evenly incorporated.
Step 3: Shape the Dough
- Roll each colored dough portion into a 14–15 inch rope.
- Place each colored rope next to one another on a large piece of parchment or plastic wrap. Gently press the doughs together and wrap them tightly to form a log.
- Twist the log slightly to create a fun swirl pattern.
- Cut the log into ½-inch pieces or use a 2–3 tablespoon scoop to portion out the dough.
Step 4: Form the Cookies
- Roll the dough portions into balls, adding extra chocolate chips on top if desired. Place the dough balls onto the prepared baking sheet, leaving 2–3 inches of space between each one.
- Bake for 9-13 minutes at 350°F, or until the edges are golden but the center is soft. The baking time will depend on the size of the cookies.
Step 5: Cool and Enjoy
- Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
- Enjoy your colorful, chewy, and chocolatey rainbow cookies!
A Few Tips for Perfect Rainbow Cookies
- Use room temperature butter: This helps the dough mix together properly and prevents flat cookies.
- Chill the dough before baking: After scooping the dough into cookie balls, place them in the fridge for 10-15 minutes to help the cookies stay thick while baking.
- Don’t over-bake: Overbaking will make the cookies dry. For a chewy texture, keep an eye on them and remove them as soon as the edges are set.

Why This Recipe Works
- Soft and Chewy Texture: The combination of butter, brown sugar, and egg yolk makes the cookies soft, thick, and chewy.
- Bright and Vibrant: Gel food colors maintain their intensity, ensuring your cookies are a true rainbow of colors.
- No Dough Chilling Required: Unlike other cookie recipes, this dough doesn’t need to be chilled, which saves time and effort.

FAQs
Can I use different types of food coloring?
Yes, you can use liquid food coloring, but gel food coloring is recommended because it provides brighter, more vibrant colors without affecting the texture of the dough.
How do I prevent my cookies from spreading too much?
Make sure your dough is not too warm when baking. Chilling the dough before baking can help prevent spreading.
Can I use gluten-free flour for this recipe?
Yes, you can substitute all-purpose flour with gluten-free flour. Make sure to choose one that is a 1:1 substitute for regular flour to maintain the texture.
