Where to Get Rainbow Chips
Rainbow chips are a fun way to dress up a standard chocolate chip cookie. Adding some color to your dough can really take the look of your treat, up a knotch!
You can usually find rainbow chips in the baking aisle of most grocery stores. I have found them at Walmart.
If you can’t find them, you can use find many different varieties on Amazon or you can substitute with white chocolate chips or any other kind of chocolate chip.
How to Make Rainbow Mickey Chips
Being the Disney lover that I am, I thought it would be fun to make Mickey Mouse-shaped rainbow chips. They were actually really easy to make.
If you want to make them, here is what you will need:
- A variety of colored Candy Melts
- Microwave-safe bowl
- Ziplock bag
- Mickey Mouse silicone mold
To make the rainbow chips, you will need to do it one color at a time. Here are the instructions:
 Melt the candy melts according to the package instructions.
 Pour the candy into a ziplock bag.
 Twist the end and use scissors to snip off the corner.
 Pipe the melted candy into the Mickey Mouse mold.
 Place the mold into the refrigerator until the candies are firm.
Ingredients Needed for Marshmallow Rainbow Chip Cookies
*Ingredient amounts are located in the recipe card at the end of this post.
Cold Butter- I used cold unsalted butter for this recipe. Using it cold helps the dough to not flatten out during baking.
Sugar- Standard white granulated sugar is used to make these cookies.
Brown Sugar- For this recipe, I used light brown sugar.
Eggs- Large eggs work best for these cookies.
Vanilla Extract- Using a good quality vanilla extract is important. I usually find that Costco has a great deal on pure vanilla extract.
All-Purpose Flour- You will need 1 1/2 cups of all-purpose flour for these cookies. Be sure to measure it correctly using the spoon and level method.
Cake Flour- Along with the all-purpose flour, you will need 1 1/2 cups of cake flour. Again, be sure to measure it correctly. Cake flour will give the cookies a chewy texture.
Powdered Milk- Adding powdered milk to the dough helps to make the cookies more tender. Powdered milk can be found at most grocery stores.
Baking Soda- This is a leavening agent that helps the cookies to rise.
Salt- Salt is added to balance out the sweetness of the cookie dough.
Rainbow Chips- These can be found in the baking aisle of most grocery stores or you can use white chocolate chips as a substitute.
Marshmallows- When I made these cookies, I was lucky enough to find rainbow marshmallows at Walmart. If you are unable to find the rainbow version, standard marshmallows can be substituted.
When to Serve Marshmallow Rainbow Chip Cookies
These cookies are great to serve when celebrating St. Patrick’s Day, Easter, Birthdays, or any other fun occasion!
How to Make Marshmallow Rainbow Chip Cookies
 Add the eggs and vanilla extract to the sugar/butter mixture and beat again. Scrape down the sides of the bowl if necessary.
 Add the flour mixture to the the wet ingredients and mix together.
 Add the rainbow chips to the cookie dough. Stir together until combined.
 Once the dough is mixed use a one-tablespoon cookie scoop to form a ball.
 Use your thumb to make an indentation in the cookie dough ball.
 Place 1/2 of a jumbo marshmallow in the indentation and fold the dough around it while forming it back into a ball.
 Place the cookie dough balls on baking sheet and refrigerate them for 30 minutes.
 Preheat your oven to 375 degrees. Space the cookie dough balls on a parchment-lined baking sheet about 2 inches apart.
 Bake the cookies for 7 minutes, then remove. Place one Rainbow Mickey Mouse Chip in the center of each cookie. Bake for an additional 30 seconds to soften the candy melt.
