How to Make Monster Cookies Recipe
Step 1: Preheat and Prepare
Start by heating your oven to 350°F (175°C) and lining your baking sheets with parchment paper. This sets you up for mess-free baking and ensures your cookies don’t stick.
Step 2: Cream the Butters and Sugars
In a large mixing bowl, beat together the creamy peanut butter, softened butter, brown sugar, and granulated sugar until the mixture is light and fluffy. This step is crucial as it creates the smooth base that carries all those wonderful flavors.
Step 3: Add Eggs and Vanilla
Mix in the eggs one at a time, then stir in the vanilla extract. This combination adds moisture and rich undertones that make the cookies irresistible.
Step 4: Incorporate Dry Ingredients
Stir in the baking soda and salt to the wet mixture, then gradually add the oats and all-purpose flour, mixing until everything is just combined. Avoid overmixing to keep your cookies tender yet chewy.
Step 5: Fold in the Chocolates and M&M’s
Finally, gently fold in the chocolate chips, M&M’s, and optional mini chocolate chips. This colorful mix adds delightful bursts of sweetness and a playful crunch to every bite.
Step 6: Scoop and Bake
Scoop out dough in 2-tablespoon portions and space them about 2 inches apart on your prepared baking sheets. Bake for 10 to 12 minutes, just until the edges turn light golden and centers set. Let your cookies cool on the baking sheet for 5 minutes before transferring them to a rack.
How to Serve Monster Cookies Recipe
Garnishes
For an extra special touch, sprinkle a few more M&M’s or mini chocolate chips on top right after baking while the cookies are still warm. A gentle dusting of powdered sugar can also add a lovely sweet contrast and make your cookies look even more inviting.
Side Dishes
These cookies pair beautifully with a cold glass of milk or a cup of hot coffee or tea. The creamy beverages complement the rich peanut butter and melt the chocolate just a little, creating a perfect flavor harmony.
Creative Ways to Present
Try stacking a few Monster Cookies between layers of vanilla ice cream for an instant, homemade ice cream sandwich. Alternatively, serve them on a colorful platter for parties or wrap them individually as thoughtful, sweet gifts.
Make Ahead and Storage
Storing Leftovers
Store your Monster Cookies in an airtight container at room temperature, and they will stay soft and chewy for up to a week. Placing a slice of bread in the container helps maintain moisture and keeps them fresh longer.
Freezing
You can freeze the cookie dough or already baked cookies. Scoop and freeze the dough balls on a baking sheet first, then transfer to a freezer bag. Cookies freeze well for up to 3 months and can be baked or thawed as needed.
Reheating
To enjoy cookies warm and melty, pop them in the microwave for 10 to 15 seconds or warm in the oven at 300°F for 5 minutes. This restores their fresh-baked softness and reactivates the chocolatey goodness.
FAQs
Can I substitute peanut butter with another nut butter?
Absolutely! While peanut butter gives the cookies their classic flavor, almond or cashew butter can work well for a twist. Just keep the same quantity, and expect a slightly different but delightful taste.
What if I don’t have old-fashioned oats?
You can use quick oats, but they will make the texture slightly less chewy. Old-fashioned oats provide the ideal chew and hold up well during baking.
Can I make these cookies gluten-free?
Yes, by swapping all-purpose flour for a gluten-free flour blend and ensuring your oats are certified gluten-free, you can enjoy these cookies without gluten concerns.
Why are my Monster Cookies spreading too much?
If your cookies are too flat, try chilling the dough for 30 minutes before baking or reduce the butter slightly. Also, make sure your baking soda is fresh for proper rising.
Is it okay to add nuts or butterscotch chips to the recipe?
Definitely! The Monster Cookies Recipe is versatile. Chopped nuts or butterscotch chips add interesting textures and flavors, so feel free to customize your batch.
