Ingredients
Bakery-Style Monster Cookies are thick with crisp edges and a perfectly soft center. The easy, no-chill cookie dough is loaded with peanut butter, oats, M&Ms, and chocolate chips, and comes together in one bowl. These are truly the best monster cookies!
Ingredients:
– 1 cup salted butter, softened at room temp (2 sticks, 16 tbsp, or 226 grams)
– 1/2 cup creamy peanut butter
– 3/4 cup granulated sugar (158 grams)
– 3/4 cup light brown sugar, packed (165 grams)
– 2 large eggs
– 1 tsp vanilla extract
– 2 and 3/4 cups all-purpose flour, spooned & leveled or weighed out (358 grams)
– 1 tsp baking soda
– 1/4 tsp salt
– 1 cup old fashioned whole rolled oats (104 grams)
– 1 and 1/4 cup M&Ms
– 1 cup semi-sweet chocolate chips (Or a mix of milk and semi-sweet, 177 grams)
How to Make Bakery-Style Monster Cookies
Step 1: Preheat the Oven
Preheat your oven to 350° F. While it heats up, line your cookie sheets with parchment paper or silicone mats to prevent sticking.
Step 2: Make the Cookie Dough
- In a large mixing bowl, use an electric mixer on high speed to cream together the softened butter until smooth.
- Add in the creamy peanut butter and mix until fully combined with the butter.
- Gradually add both sugars and continue mixing on high for about 1 minute until well creamed.
- Incorporate the eggs and vanilla extract into the mixture until just combined.
Step 3: Finish the Cookie Dough
- Gradually add the all-purpose flour, baking soda, and salt into the mixture. Mix gently until no dry ingredients remain visible.
- Finally, fold in the oats, M&Ms, and chocolate chips using low speed to ensure even distribution throughout the dough.
Step 4: Scoop into Balls
Scoop out portions of dough using a large cookie scoop that holds about 4 tablespoons. Alternatively, weigh each ball to about 4 ounces (115 grams) for uniformity. If desired, quick chill the dough balls in the freezer for 20-30 minutes if you notice they’re spreading too much.
Step 5: Bake
Place your scooped dough balls on prepared cookie sheets with enough space between them (about two inches). Bake in the preheated oven for about 10-13 minutes. The edges should be set while the centers may look underdone; this is normal!
Step 6: Serve + Store
Enjoy your freshly baked cookies warm from the oven! Allow them to cool completely on a rack before storing in an airtight container at room temperature; they last around 3–5 days.
Step 7: Make-Ahead Tips
You can prepare cookie dough ahead of time:
* Fridge: Keep scooped cookie balls chilled in an airtight container for up to three days.
* Freezer: Freeze scooped balls for about two months; bake directly from frozen without thawing!
Now you’re equipped with everything needed to make Bakery-Style Monster Cookies that will delight everyone who tries them!

Common Mistakes to Avoid
To ensure your Bakery-Style Monster Cookies turn out perfectly every time, avoid these common mistakes.
- Using cold butter: Make sure your butter is softened to room temperature for easy creaming and the right texture.

- Not spacing the cookies enough: Leave adequate space between each cookie on the baking sheet to allow for spreading during baking.
- Ignoring bake time: Keep an eye on the cookies as they bake; they may look underdone but will firm up as they cool.
