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 (175°C). Line your cookie sheets with parchment paper or silicone baking mats to prevent sticking.
Step 2: Make the Cookie Dough
In a large mixing bowl, cream the softened butter using an electric mixer on high speed until well combined. Add the creamy peanut butter and continue mixing until both are thoroughly blended. Then add the granulated sugar and light brown sugar; mix on high speed for at least one minute until creamed together. Finally, incorporate the eggs and vanilla extract until just combined.
Step 3: Finish the Cookie Dough
Add the all-purpose flour, baking soda, and salt to the mixture. Mix just until you can no longer see dry ingredients in the batter. Scrape down the sides of the bowl as needed. Lastly, fold in the oats, m&ms, and semi-sweet chocolate chips using low speed to ensure even distribution throughout.
Step 4: Scoop into Balls
Using a large cookie scoop that holds about four tablespoons of dough or weighing out portions at approximately four ounces each (115 grams), scoop out balls of dough onto your lined cookie sheets. If desired, chill them in the freezer for about 20–30 minutes for better shape during baking.
Step 5: Bake
Place your cookie balls on the prepared sheets with about two inches between each ball. Bake for approximately 10–13 minutes until edges appear set but centers may look slightly underdone — this is normal! Allow them to cool on their sheet briefly before gently flattening with the back of a measuring cup if desired.
Step 6: Serve + Store
These cookies taste best warm straight from the oven! Once cool enough to handle them safely, transfer cookies to a cooling rack until completely cooled before storing in an airtight container. They’ll stay fresh for about three to five days at room temperature.
Step 7: Make-Ahead Tips
If you’re looking to prepare cookie dough in advance:
– Fridge: You can keep scooped dough balls stored in an airtight container in your fridge for up to three days.
– Freezer: Freeze cookie dough balls for around two months; bake directly from frozen without thawing!
With these steps completed, you now have delicious Bakery-Style Monster Cookies ready for any occasion!

Common Mistakes to Avoid
Avoiding mistakes in your baking process can make all the difference. Here are some common pitfalls to watch out for when making Bakery-Style Monster Cookies:
-
Incorrect Measurements: Always use accurate measurements for ingredients. Using too much flour or sugar can alter the texture and taste of your cookies.
-
Not Prepping Ingredients: Make sure all ingredients are at room temperature before you begin. This helps in achieving a smooth dough and properly mixed flavors.
-
Overmixing the Dough: Mix the dough just until combined after adding dry ingredients. Overmixing can lead to tough cookies instead of soft ones.
-
Skipping the Baking Time Check: Each oven is different; keep an eye on your cookies as they bake. They may look underdone but will firm up as they cool.
-
Chilling Dough Too Long: While chilling can help, excessive chilling can lead to a dough that won’t spread properly. If you chill, don’t exceed 48 hours.
