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: Prep the Oven
Preheat the oven to 350° F. Although these cookies don’t require chilling, you can refrigerate the dough for up to 48 hours if desired. Line cookie sheets with parchment paper or silicone baking mats.
Step 2: Make the Cookie Dough
In a very large mixing bowl, cream the softened butter using an electric mixer on high speed until smooth. Add the creamy peanut butter and mix until fully combined. Next, add both sugars and continue mixing on high speed for at least one minute until well creamed. Beat in the eggs one at a time along with vanilla extract until just combined.
Step 3: Finish the Cookie Dough
Gradually add the flour along with baking soda and salt into the mixture. Mix just until no dry ingredients remain visible. Scrape down the sides of the bowl as needed. Finally, fold in the oats, m&ms, and chocolate chips using low speed to ensure they are evenly distributed throughout.
Step 4: Scoop into Balls
Using a large cookie scoop that holds about four tablespoons of dough (or weighing out each ball to approximately four ounces), scoop out portions of dough onto the prepared cookie sheets. Leave enough space between each ball as they will spread during baking.
Step 5: Bake
Place your cookie sheets into the preheated oven. Bake for about 10–13 minutes. The edges should look set while centers may appear underbaked—that’s normal! If necessary, gently flatten cookies using a measuring cup once they come out of the oven.
Step 6: Serve + Store
Enjoy your Bakery-Style Monster Cookies warm from the oven! Allow them to cool completely on a cooling rack before storing them in an airtight container where they’ll last for about three to five days at room temperature.
Step 7: Make-Ahead Tips
If you want to prepare ahead of time:
– Fridge: Store scooped cookie dough balls in an airtight container for up to three days.
– Freezer: Freeze cookie dough balls for about two months; bake directly from frozen without thawing!
Now you’re ready to enjoy some delicious Bakery-Style Monster Cookies!

How to Perfect Bakery-Style Monster Cookies
To achieve the best results with your Bakery-Style Monster Cookies, follow these helpful tips.
- Use Room Temperature Ingredients: Ensure butter and eggs are at room temperature for better mixing and texture.
- Measure Flour Accurately: Spoon and level flour instead of scooping directly from the bag to avoid dense cookies.
- Don’t Overmix: Mix just until ingredients are combined to keep your cookies tender.
- Chill Dough for Extra Thickness: If you want thicker cookies, chill the dough for 30 minutes before baking.
- Monitor Baking Time: Keep an eye on them while baking; they should look set around the edges but soft in the center.
- Cool Completely Before Storing: Allow cookies to cool completely on a rack before placing them in an airtight container.
Best Side Dishes for Bakery-Style Monster Cookies

Common Mistakes to Avoid
Making Bakery-Style Monster Cookies can be a breeze, but a few common mistakes might hinder your cookie perfection. Here are some tips to keep in mind.
- Using Cold Ingredients: Always ensure your butter is softened at room temperature. Cold butter won’t cream well with the sugars, resulting in dense cookies.
- Overmixing the Dough: Mix just until the dry ingredients are combined. Overmixing leads to tough cookies instead of soft and chewy ones.
- Not Measuring Flour Accurately: Spoon and level your flour or use a kitchen scale. Too much flour can make your cookies dry and crumbly.
- Skipping the Parchment Paper: Lining your baking sheets prevents sticking and ensures even baking. Skipping this step could result in cookie chaos.
- Ignoring Bake Time: Keep an eye on the bake time. Cookies may appear underdone; they will firm up as they cool, so don’t overbake!
