Step-by-Step Instructions
1. Preheat the Oven
Set your oven to 350°F (175°C). Line your baking sheets with parchment paper or silicone baking mats to prevent sticking.
2. Mix Wet Ingredients
In a large mixing bowl, combine the peanut butter, granulated sugar, and brown sugar. Beat until the mixture is smooth and creamy. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
3. Incorporate Dry Ingredients
In a separate bowl, whisk together the baking soda and salt. Gradually add this to the wet mixture, stirring until just combined. Fold in the rolled oats, chocolate chips, and M&M’s, ensuring even distribution throughout the dough.
4. Shape the Cookies
Using a large cookie scoop or your hands, form dough balls approximately 2 tablespoons in size. Place them on the prepared baking sheets, spacing them about 2 inches apart to allow for spreading.
5. Bake
Bake in the preheated oven for 10-12 minutes, or until the edges are golden brown and the centers are set. The cookies will continue to firm up as they cool.
6. Cool
Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a cooling rack to cool completely.

Health Benefits
While colossal cookies recipe are definitely a treat, I like to think of them as a little indulgence with a few hidden perks. Thanks to the oats in the recipe, I get a good dose of fiber, which helps keep me full and supports digestion.
The peanut butter adds some plant-based protein and healthy fats that give me lasting energy—especially helpful when I need a quick pick-me-up in the afternoon.
Even the dark chocolate chips offer a small boost of antioxidants. Of course, these cookies are still a dessert, but enjoying one in moderation gives me the comfort I crave, without totally derailing my healthy habits.
Special Tips for Colossal Cookies Recipe
- Chill the Dough (Optional but Worth It):
If you have extra time, I chill the dough for 30 minutes before baking. It helps the cookies hold their shape and enhances the flavor. - Don’t Overmix:
Once I add the dry ingredients, I mix just until combined. Overmixing makes the cookies tough instead of chewy. - Use a Cookie Scoop or Scale:
For that bakery-style look, I use a large cookie scoop or weigh out each dough ball. This keeps the cookies uniform in size and ensures even baking. - Underbake Slightly:
I always take them out when the centers look just a little underdone. They finish baking on the sheet and stay soft inside. - Customize Add-ins:
I switch it up depending on what I have—chopped nuts, pretzel pieces, mini marshmallows, or crushed candy bars all work beautifully. - Use Parchment or Silicone Mats:
I never skip this. It keeps the cookies from spreading too much and makes cleanup easier. - Let Them Cool on the Sheet:
I leave them on the hot baking tray for 5–7 minutes before moving to a cooling rack. That firm-up time is crucial.
How to Store Colossal Cookies
Let the cookies cool completely, then store them in an airtight container at room temperature for up to 5 days.
To keep them soft, add a slice of bread inside the container. For longer storage, freeze the cookies individually wrapped and reheat in the microwave when needed.
Note
This recipe yields a large batch, making it perfect for gatherings, bake sales, or sharing with friends and family. The dough freezes well, allowing for fresh-baked cookies anytime.

Baking these colossal cookies recipe brings joy not just in the eating, but in the making. The combination of textures and flavors creates a cookie that’s both nostalgic and indulgent.
