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.
