Ingredients
Bakery-Style Monster Cookies require simple yet delicious ingredients that come together beautifully.
For the Cookie Dough:
- 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). This ensures that your cookies bake evenly right from the start. Line your baking sheets with parchment paper or silicone mats.
Step 2: Make the Cookie Dough
In a large mixing bowl, cream together the softened butter using an electric mixer on high speed until smooth. Add the peanut butter and continue mixing until well combined. Gradually incorporate the granulated sugar and light brown sugar until fully creamed together.
Step 3: Add Eggs and Vanilla
Add two large eggs and one teaspoon of vanilla extract into the creamed mixture. Mix on medium speed until just combined.
Step 4: Finish the Cookie Dough
To the mixture, add two and three-fourths cups of all-purpose flour along with one teaspoon of baking soda and one-fourth teaspoon salt. Mix just until no dry flour remains. Finally, fold in one cup of old-fashioned oats, one and one-fourth cups of M&Ms, and one cup of semi-sweet chocolate chips using a spatula.
Step 5: Scoop into Balls
Using a large cookie scoop or weighing about four ounces (115 grams) each, scoop out portions of dough onto your prepared cookie sheets. Space them about two inches apart.
Step 6: Bake Cookies
Bake in the preheated oven for about 10–13 minutes. The edges should look set while the centers may appear slightly underbaked. Remember that they will firm up as they cool.
Step 7: Cool and Store
Allow cookies to cool on a cooling rack completely before storing them in an airtight container. Enjoy fresh out of the oven or store them for later—these cookies last about three to five days at room temperature!
Enjoy making these delicious Bakery-Style Monster Cookies! They’re sure to become a favorite treat in no time!

How to Perfect Bakery-Style Monster Cookies
Achieving the ideal texture and flavor in your Bakery-Style Monster Cookies is simple with the right techniques. Here are some tips to ensure your cookies turn out perfectly every time.
-
Use room temperature ingredients: Ensure your butter and eggs are at room temperature; this helps them blend better, resulting in a smoother dough.
-
Don’t overmix the dough: Mix just until the dry ingredients are incorporated to maintain the softness of the cookies.
-
Use high-quality chocolate chips: Opt for semi-sweet or mixed chocolate chips for richer flavor. Quality chocolate elevates your cookies significantly.
-
Measure flour correctly: Spoon flour into measuring cups instead of scooping directly from the bag. This prevents dense cookies caused by excess flour.
-
Watch the baking time: Start checking your cookies at around 10 minutes. They should look slightly underbaked as they will continue to firm up while cooling.
-
Cool on wire racks: Allow your cookies to cool completely on wire racks to prevent sogginess and maintain their crisp edges.

Common Mistakes to Avoid
When baking Bakery-Style Monster Cookies, even small errors can lead to disappointing results. Here are some common mistakes to steer clear of:
-
Ignoring the Butter Temperature: Using cold butter instead of softened can result in dense cookies. Let your butter sit at room temperature until soft for the best texture.
-
Overmixing the Dough: Mixing the dough too much after adding flour can make cookies tough. Mix just until the dry ingredients are incorporated for a chewy texture.
-
Not Measuring Flour Correctly: Too much flour can lead to dry cookies. Use the spoon and level method or a kitchen scale for accuracy.
-
Skipping Parchment Paper: Baking directly on a cookie sheet without parchment can lead to sticking and uneven baking. Always line your baking sheets for easy removal and cleanup.
-
Underbaking the Cookies: These cookies may look underdone when they come out of the oven. Bake until edges are set but centers are still soft; they will continue cooking as they cool.
-
Neglecting to Space Out Dough Balls: Crowding cookie sheets will cause cookies to merge while baking. Ensure adequate space (about 2 inches) between dough balls.

Storage & Reheating Instructions
Refrigerator Storage
- Store cookies in an airtight container at room temperature for up to 3-5 days.
- For unbaked cookie dough, keep it in an airtight container in the fridge for 1-3 days before baking.
Freezing Bakery-Style Monster Cookies
- Freeze baked cookies in an airtight container for up to 2 months.
- For cookie dough, scoop balls onto a baking sheet, freeze until solid, then transfer to a freezer bag or container. Bake from frozen without thawing.
Reheating Bakery-Style Monster Cookies
- Oven: Preheat your oven to 350°F and warm cookies for about 5-10 minutes.
