All-Purpose Flour (2 ¼ cups) – Forms the base of the cookie dough.

Substitutions and Variations

Mini M&Ms: If you prefer smaller bits of candy in each bite, use mini M&Ms instead of the regular-sized ones.

Add Nuts: For extra crunch, add ½ cup of chopped nuts, like pecans or walnuts.

Step-by-Step Cooking Instructions

Follow these easy steps to create colorful, delicious Rainbow M&M cookies.

Step 1: Prepare the Ingredients

Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats.
Make sure your butter is softened to room temperature. If it’s not, you can soften it in the microwave in short 10-second intervals until just soft.

Step 2: Cream the Butter and Sugars

In a large mixing bowl, beat the butter, granulated sugar, and brown sugar together using an electric mixer or stand mixer. Beat on medium speed for about 2-3 minutes, or until the mixture is light and fluffy. Creaming the butter and sugars properly is essential for creating a soft, chewy texture.
Add the eggs one at a time, beating well after each addition.
Mix in the vanilla extract until combined.

Step 3: Combine the Dry Ingredients

In a separate bowl, whisk together the flour, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Avoid overmixing, as this can result in tougher cookies.

Step 4: Fold in the M&Ms

Gently fold in the M&Ms and chocolate chips (if using) into the dough using a spatula. Reserve about ¼ cup of the M&Ms to press into the tops of the cookies before baking. This ensures the cookies have those bright pops of color on top.

Step 5: Shape the Cookies

Using a cookie scoop or tablespoon, scoop about 1 ½ tablespoons of dough and roll it into balls. Place them on the prepared baking sheets, leaving about 2 inches of space between each cookie to allow for spreading.
Gently press a few of the reserved M&Ms on top of each cookie dough ball for a decorative finish.

Step 6: Bake the Cookies

Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden, but the centers still look slightly underbaked. This will give you a soft and chewy texture once the cookies cool.
Remove the cookies from the oven and let them cool on the baking sheets for about 5 minutes before transferring them to a wire rack to cool completely.

How to Make Rainbow M&M Cookies: A Step-by-Step Guide

Cream the butter and sugars: Beat until fluffy for a soft cookie base.
Mix in dry ingredients: Gradually incorporate the dry ingredients into the wet mixture.
Add M&Ms: Gently fold in the M&Ms and chocolate chips.
Shape and bake: Form dough balls, press in extra M&Ms, and bake until the edges are golden.

Common Mistakes to Avoid

Overmixing the Dough: Be careful not to overmix once you’ve added the flour, as this can lead to denser cookies. Mix just until combined.
Overbaking: M&M cookies will continue to cook as they cool on the baking sheet. Take them out of the oven when the centers still look soft for perfectly chewy cookies.
Using Cold Ingredients: Make sure your butter and eggs are at room temperature. Cold ingredients can prevent the dough from mixing properly, leading to uneven texture.

Serving and Presentation Tips

How to Serve Rainbow M&M Cookies

Serve Fresh and Warm: Rainbow M&M cookies are best enjoyed warm, fresh out of the oven. The chocolate will be slightly melted, and the cookie centers will be perfectly chewy.
With Ice Cream: Create a fun dessert by serving these cookies with a scoop of ice cream for a cookie sandwich.
Party Platters: Arrange them on a colorful platter with a mix of other treats for a fun party display.

Presentation Ideas for Rainbow M&M Cookies

Colorful Stacking: Stack the cookies on a serving tray and sprinkle extra M&Ms around for a burst of color.
Gift Packaging: These cookies make great gifts. Place them in a decorative tin or a cellophane bag tied with a colorful ribbon for a homemade touch.
Holiday Variations: Use seasonal M&Ms for different holidays (red and green for Christmas, pastels for Easter, or red, white, and blue for 4th of July).

Rainbow M&M Cookie Recipe Tips

Chill the Dough: If you want thicker cookies that don’t spread too much, chill the cookie dough for 30 minutes before baking. This step is optional but can improve the texture of your cookies.
Extra Gooeyness: For extra gooey, chocolatey cookies, press a few chocolate chips into the top of the cookies right after they come out of the oven.
Storage: Store these cookies in an airtight container at room temperature for up to 5 days. For longer storage, freeze them in an airtight container for up to 3 months. Thaw at room temperature before serving.

Frequently Asked Questions (FAQs)

Q: Can I use peanut butter M&Ms in this recipe?
A: Yes! Peanut butter M&Ms would be a delicious variation. You may need to chop them slightly since they are larger than regular M&Ms.

Q: Why did my cookies spread too much?
A: If your cookies spread too much, it could be due to butter that was too soft or warm. Chilling the dough for 30 minutes before baking can help prevent excess spreading.

Q: Can I freeze the cookie dough?
A: Absolutely! You can freeze the cookie dough in balls and bake them straight from the freezer. Just add an extra minute or two to the baking time.

Q: How can I make the cookies softer?
A: If you prefer extra-soft cookies, slightly underbake them by 1-2 minutes. The centers should still look slightly underdone when you take them out of the oven.
