Ingredients
To create these delicious Bakery-Style Monster Cookies, gather the following 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). Prepare your baking sheets by lining them with parchment paper or silicone baking mats.
Step 2: Make the Cookie Dough
In a large mixing bowl:
1. Cream the softened butter using an electric mixer on high speed until smooth.
2. Add the creamy peanut butter; mix until well combined.
3. Incorporate both sugars into the mixture; blend until fully creamed for about one minute.
4. Beat in the eggs and vanilla extract until just combined.
Step 3: Finish the Cookie Dough
Add the following dry ingredients into the bowl:
1. Flour, salt, and baking soda; mix until just combined.
2. Gently fold in old-fashioned oats, m&ms, and semi-sweet chocolate chips using low speed.
Step 4: Scoop into Balls
Using a cookie scoop that holds about four tablespoons of dough (or weigh out each ball to be roughly four ounces):
* Scoop dough onto prepared cookie sheets leaving space between each ball.
* Optionally chill in the freezer for about 20–30 minutes if you prefer less spreading during baking.
Step 5: Bake
Place trays in the oven:
1. Bake for approximately 10–13 minutes until edges are set.
2. If cookies appear underdone but edges are firm, they will continue to cook once removed from heat.
Step 6: Serve + Store
Once baked:
* Allow cookies to cool on a cooling rack before storing in an airtight container.
* Enjoy warm or store at room temperature for up to five days.
Step 7: Make-Ahead Tips
For future batches:
1. Refrigerate scooped dough balls in an airtight container for up to three days before baking.
2. Freeze cookie dough balls for two months; bake directly from frozen without thawing.

To ensure your Bakery-Style Monster Cookies turn out perfectly every time, follow these helpful tips.
Use Room Temperature Ingredients: Make sure your butter and eggs are at room temperature for optimal mixing and texture.
Measure Flour Correctly: Spoon flour into measuring cups and level it off to avoid using too much, which can make cookies dry.
Don’t Overmix: Mix the dough until just combined to keep the cookies tender and chewy.
Adjust Baking Time: Keep an eye on your cookies while baking. They should look slightly underbaked when you remove them from the oven.
Store Properly: Allow cookies to cool completely before storing them in an airtight container to maintain freshness.

Common Mistakes to Avoid
Baking Bakery-Style Monster Cookies can be a delightful experience, but there are common mistakes that can affect the outcome. Here are some to watch out for.

- Skipping Measurements: Not measuring ingredients accurately can ruin the dough. Use a kitchen scale or measuring cups for precision.
- Overmixing the Dough: Overmixing can result in tough cookies. Mix just until the ingredients are combined.
- Not Prepping Baking Sheets Properly: Skipping parchment paper or silicone mats can cause sticking. Always line your sheets for easy removal.
- Ignoring Bake Time: Each oven is different, and cookies may need more or less time. Keep an eye on them and do a test bake if unsure.

Storage & Reheating Instructions
Refrigerator Storage
- Store in an airtight container for up to 5 days.
- Place parchment paper between layers to prevent sticking.
Freezing Bakery-Style Monster Cookies
