Step‑by‑Step Instructions for Peanut Butter Oatmeal Monster Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This is crucial for achieving the perfect texture in your Peanut Butter Oatmeal Monster Cookies. While the oven warms, line two baking sheets with parchment paper to ensure easy cleanup and prevent sticking.
Step 2: Mix Wet Ingredients
In a large mixing bowl, cream together 1/2 cup of softened unsalted butter, 1/2 cup granulated sugar, 1/2 cup light brown sugar, and 1/2 cup peanut butter using an electric mixer on medium speed. Mix until the mixture is smooth and creamy, taking about 2-3 minutes. This step creates the luscious base for your cookies.
Step 3: Incorporate Egg and Vanilla
Add 1 room-temperature egg and 1 teaspoon of pure vanilla extract to the creamy mixture. Beat them in on low speed until fully combined, ensuring a homogeneous mixture. The egg acts as a binder, giving your Peanut Butter Oatmeal Monster Cookies structure and moisture.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together 1 cup of all-purpose flour, 1 1/4 cups of old-fashioned rolled oats, 1/4 teaspoon of salt, 1/2 teaspoon of baking powder, and 1/2 teaspoon of baking soda. This blending of dry ingredients is essential for even distribution of flavors and leavening agents throughout your cookie batter.
Step 5: Blend Dry Ingredients with Wet Mixture
Gradually add the dry ingredients to the wet mixture during gentle mixing. Stir until just combined—avoid overmixing, as this can lead to flat cookies. The dough should be thick and cohesive, showcasing the heartiness of your Peanut Butter Oatmeal Monster Cookies.
Step 6: Fold in Add-Ins
Gently fold in 3/4 cup of colorful M&M candies and 1/2 cup of semi-sweet chocolate chips using a spatula. This step adds a playful touch to your cookies, ensuring every bite is bursting with sweetness and fun. The vibrant colors of the M&Ms will make these cookies irresistible!
Step 7: Chill the Dough (Optional)
If you prefer a thicker cookie, roll the dough into a ball and refrigerate it for about 30 minutes. This optional step will enhance the texture of your Peanut Butter Oatmeal Monster Cookies, resulting in a delightful treat that holds its shape beautifully.
Step 8: Scoop Dough onto Baking Sheets
Use a spoon or cookie scoop to drop generous spoonfuls of dough onto your prepared baking sheets, spacing them about 2 inches apart. This spacing allows the cookies to spread evenly while baking, ensuring that your Peanut Butter Oatmeal Monster Cookies turn out perfectly golden and chewy.
Step 9: Bake the Cookies
Place the baking sheets in the oven and bake for 12 minutes or until the edges are lightly golden. The cookies will look soft in the center, which is exactly what you want for that chewy texture. Keep an eye on them as baking times may vary slightly based on your oven.
Step 10: Cool the Cookies
Once baked, remove the cookies from the oven and allow them to cool on the baking sheets for 5 minutes. This cooling period helps the cookies firm up before transferring them to a wire rack to cool completely. Enjoy your delicious Peanut Butter Oatmeal Monster Cookies once they’ve cooled!

Peanut Butter Oatmeal Monster Cookies Recipe FAQs
How do I select the best peanut butter for my cookies?
I recommend using a creamy, natural peanut butter that doesn’t contain any added sugar or hydrogenated oils. Look for a product with just peanuts and salt for the best flavor. If you’re opting for nut-free, sunflower seed butter works wonderfully as an alternative!
What’s the best way to store Peanut Butter Oatmeal Monster Cookies?
To keep your cookies fresh, store them in an airtight container at room temperature for up to 5 days. If your kitchen tends to be warm, it’s a good idea to refrigerate them for up to a week to maintain their delicious texture.
Can I freeze Peanut Butter Oatmeal Monster Cookies?
Absolutely! For freezing, lay the cookies in a single layer on a baking sheet and freeze until solid. Then, transfer them to an airtight container or freezer bag, where they can last up to 3 months. When you’re ready to enjoy them, you can bake them from frozen at 350°F (175°C) for about 8-10 minutes.
What if my cookies turn out too flat?
If your cookies spread too much, it could be due to overmixing the dough or not using butter at the right temperature. Make sure to cream the butter and sugars just until combined and avoid overmixing once you’ve added the dry ingredients. Chilling the dough for about 30 minutes can also enhance their thickness.
Are these cookies safe for kids with nut allergies?
Great question! If making these cookies for someone with nut allergies, be sure to substitute the peanut butter with a safe alternative, like sunflower seed butter. Always double-check labels on ingredients to ensure they are free from allergens.

To maintain that chewy texture in your Peanut Butter Oatmeal Monster Cookies, be careful not to overbake them. When the edges are lightly golden and the centers still look soft, they are done! Let them cool on the baking sheet for a few minutes before transferring them to a wire rack.
