Homemade Rainbow Chip Cookies Ingredient Breakdown
- All-purpose Flour, Baking Soda and Salt: Your essential dry ingredients. Baking soda gives lift to the cookies and salt balances sweetness from sugar
- Melted Butter: The melted butter provides the right amount of crust and an overall even bake in each cookie
- Sugars: Sugar tenderizes the cookie dough and adds to the softness of the cookie. Although tempting, I don’t recommend cutting down the sugar. I personally cut down on the sugar content in most recipes, and I considered this when designing this recipe
- Eggs: Add fat and binds the rainbow chip cookie dough together
- Vanilla: Essential flavouring
- Rainbow Bit Chips: Rainbow Bit Chips make this recipe! If you live in Ontario you can search for them at Bulk Barn or Sweetapolita. An alternative are mini M&Ms, which also tastes amazing in this recipe
- Butterscotch Chips: The butterscotch chips adds some sweetness from the sugar we previously cut out. It also reminds me of a “pot of gold” we would find at the end of the rainbow!

How to Make Rainbow Chip Cookies
- Preheat oven: Preheat the oven to 350ยฐF. Cookies bake the best in ovens that are properly heated to the correct temperature.
- Mix dry ingredients: In a mixing bowl, combine all dry ingredients (flour, salt, baking soda) and whisk to combine.
- Mix wet ingredients: In another mixing bowl, whisk the melted butter and sugars together.
- Add in eggs: Then add the eggs one at a time to the wet ingredients, whisk to combine. Whisk in the vanilla extract.
- Fold in the fun stuff: Fold in the rainbow bit chips (or M&MS) and the butterscotch chips.
- Scoop: Use a cookie scoop to scoop the cookie dough on baking trays. Add in extra butterscotch chips (optional). Do not flatten the cookies, they will spread on their own.
- Bake: Bake for 12 minutes, remove the cookies and let cool on the baking tray for another 5 minutes. Then transfer to a cooling rack to cool completely.
