Step‑by‑Step Instructions for Peanut Butter Oatmeal Monster Cookies
Step 1: Prep Dough
In a large mixing bowl, cream together 1 cup softened butter, ½ cup granulated sugar, and ½ cup light brown sugar using an electric mixer on medium speed until the mixture is light and fluffy, about 3–5 minutes. Gradually beat in 1 cup creamy peanut butter, 1 large egg, and 1 teaspoon vanilla extract until completely smooth and well-combined.
Step 2: Combine Dry Ingredients
In a separate bowl, whisk together 1½ cups all-purpose flour, 1 cup old-fashioned rolled oats, ½ teaspoon salt, 1 teaspoon baking powder, and ½ teaspoon baking soda to ensure even distribution of the dry ingredients. Gradually add this dry mixture into your wet mixture, stirring gently until just combined, taking care not to overmix for perfect Peanut Butter Oatmeal Monster Cookies.
Step 3: Add Mix-Ins
Fold in 1 cup of M&Ms and 1 cup of semi-sweet chocolate chips using a spatula until they are evenly distributed throughout the cookie dough. The colorful M&Ms will add a pop of fun and sweetness, while the chocolate chips create rich, melty bursts in each bite of your delightful cookies.
Step 4: Chill (optional)
For thicker cookies, cover the dough with plastic wrap and chill it in the refrigerator for about 30 minutes. This step helps the cookies hold their shape while baking and enhances the chewy texture, making your Peanut Butter Oatmeal Monster Cookies even more irresistible.
Step 5: Bake
Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper while waiting for the oven to reach temperature. Using a cookie scoop, drop rounded tablespoons of dough onto the prepared sheets, spacing them about 2 inches apart. Bake for 10–12 minutes, or until the edges are golden brown and the centers look set.
Step 6: Cool
Once baked to perfection, remove the sheets from the oven and let your Peanut Butter Oatmeal Monster Cookies cool on the baking sheets for about 5 minutes. Then, carefully transfer them to a wire rack to cool completely, allowing the textures to settle and the flavors to meld beautifully in each cookie.

Expert Tips for Peanut Butter Oatmeal Monster Cookies
- Butter Temperature: Ensure you’re using softened butter, not melted, for the right consistency. This keeps your cookies rich and chewy.
- Mixing Technique: Avoid overmixing the dough; mix just until the ingredients are combined. This prevents flat cookies and maintains the perfect texture.
- Chill for Thickness: For an extra thick cookie, chilling the dough for 30 minutes is a game changer. This step helps prevent excessive spreading during baking.
- Baking Time Awareness: Keep a close eye on your cookies as they bake. They’ll firm up as they cool, so avoid overbaking for that soft, chewy center.
- Storage Tips: Store your Peanut Butter Oatmeal Monster Cookies in an airtight container at room temperature for optimal freshness.
Make Ahead Options
These Peanut Butter Oatmeal Monster Cookies are perfect for meal prep, allowing you to enjoy fresh-baked goodness without the time crunch during busy weekdays. You can prepare the cookie dough up to 24 hours in advance; simply cover it tightly with plastic wrap and refrigerate. For even longer storage, shape the dough into balls and freeze them for up to 3 months. When you’re ready to bake, you can either let the frozen dough thaw in the fridge overnight or bake directly from frozen, adding a couple of extra minutes to the baking time. This way, you’ll have delicious, homemade cookies on hand at a moment’s notice—just as delightful as if they were freshly made!
Peanut Butter Oatmeal Monster Cookies Recipe FAQs
How do I choose the right peanut butter?
Absolutely! When selecting peanut butter, go for a creamy variety for the best texture in your cookies. If allergies are a concern, sunflower seed butter is a wonderful alternative. Ensure the peanut butter you choose has no added sugars or oils for the cleanest flavor.
What is the best way to store Peanut Butter Oatmeal Monster Cookies?
You’ll want to keep those cookies scrumptious! Store them in an airtight container at room temperature for up to 5 days. This retains their chewy texture and delightful flavor. If they start to dry out, toss a slice of bread into the container—this helps maintain moisture!
Can I freeze the cookie dough for later use?
Yes, freezing is a fantastic option! Shape your cookie dough into balls and place them on a baking sheet to freeze until firm (about 1-2 hours). Then, transfer the dough balls to a zip-top bag and store them in the freezer for up to 3 months. When you’re ready to bake, no need to thaw—just bake straight from frozen, adding a couple of extra minutes to the baking time.
What if the cookies turn out too flat?
Very! If your cookies spread too much and end up flat, it might be due to using melted butter instead of softened butter. Also, overmixing or not chilling the dough can contribute to spreading. Next time, make sure to use softened butter, mix just until combined, and consider chilling the dough for about 30 minutes before baking.
Can I make these cookies vegan or gluten-free?
Of course! For a vegan option, use a flax egg—combine 1 tablespoon of ground flaxseed with 3 tablespoons of water, let it sit until gel-like, then mix in as you would a regular egg. To make them gluten-free, simply substitute all-purpose flour with a 1:1 gluten-free flour blend. This way, everyone can enjoy these delightful Peanut Butter Oatmeal Monster Cookies!
