Ingredients
- Brown sugar — Adds moisture, depth of flavor, and chewiness thanks to its molasses content.
- White sugar — Provides sweetness and helps the cookies brown and spread slightly for contrast in texture.
- Butter — Adds richness and helps create a tender, flavorful cookie. Salted or unsalted both work.
- Creamy peanut butter — The base peanut flavor and fat content keep the cookies dense, moist, and chewy. Use a stable, creamy brand; all-natural peanut butter can be too dry.
- Eggs — Bind the ingredients and contribute to a soft texture.
- Vanilla extract — Enhances and rounds the flavors.
- Baking soda — A leavening agent that gives a slight lift and lightness to the cookies.
- Salt — Balances sweetness and enhances overall flavor.
- Quick oats — Provide the characteristic oatmeal texture and chewiness. If you are highly sensitive to gluten, choose oats labeled gluten-free.
- Chocolate chips — Offer pockets of melty chocolate that pair beautifully with peanut butter.
- M&Ms — Add crunch, sweetness, and a colorful, playful touch to the cookies.

How to Make Oatmeal Monster Cookies
This flourless monster cookie recipe is straightforward and ideal for bakers of any skill level. Follow these steps:
- Preheat the oven to 350°F (175°C).
- Cream the sugars and butter in a large bowl until light and smooth.
- Add peanut butter, eggs, and vanilla and beat until the mixture is creamy and uniform.
- Stir in baking soda, salt, and quick oats. Start with the lower end of the oat range and add more if needed to reach the desired dough thickness.
- Fold in chocolate chips and M&Ms until evenly distributed.
- Drop dough by tablespoonfuls or with a cookie scoop onto greased or lined baking sheets, leaving space for spreading.
- Bake 10–11 minutes, or until the bottom edges are lightly browned. For very puffy cookies, gently drop the cookie sheet onto the counter once or twice after removing it from the oven to flatten them slightly.
- Cool on the baking sheet for about 1 minute, then transfer to a wire rack to cool completely.
Serve warm or cooled. These cookies freeze well for longer storage.
How to Store GF Oat Cookies
Allow cookies to cool completely before storing. Place layers of cookies in an airtight container separated by parchment paper to prevent sticking. Stored at room temperature, they stay fresh for up to a week.
This Amish recipe makes a large batch — roughly sixty cookies — so freezing a portion is a good idea. Freeze cookies in a single layer or in a container with parchment between layers. Thaw at room temperature for about 30 minutes before serving, or enjoy them straight from the freezer if you prefer.
Variations
- Oat types: Use old-fashioned oats for a heartier chew or combine quick and old-fashioned oats for varied texture.
- Nut add-ins: Stir in chopped peanuts, walnuts, or pecans for extra crunch.
- Swap mix-ins: Substitute M&Ms with Reese’s Pieces, use white chocolate or peanut butter chips, or add dried fruit like raisins.
- Dairy-free: Use dairy-free butter and dairy-free chocolate chips. Omit candy-coated chocolates or use a vegan alternative if available.
- Seasonal colors: Customize M&M colors for holidays (red and green for Christmas, red/white/blue for patriotic events).
- Spices: Add cinnamon, nutmeg, or a pinch of chili powder for warmth and complexity.
Monster Cookie Recipe No Flour
Because this recipe uses oats and no wheat flour, it’s naturally gluten-free. Oats themselves are gluten-free, but they can be cross-contaminated during processing. If you are very sensitive to gluten, be sure to buy oats specifically labeled gluten-free.
These flourless monster cookies are reliably soft and chewy while still offering plenty of peanut-butter flavor and chocolatey goodness. They’re a great example of a naturally gluten-free cookie that doesn’t sacrifice texture or taste.
Why Are They Called Monster Cookies?
The exact origin of the name is unclear, but a few likely reasons exist: the cookies are often large (“monster” size), covered in bumpy, colorful M&M’s, or simply “monstrously” delicious. Whatever the reason, the playful name suits these bold, colorful cookies.
My Amish Dad’s Favorite Cookies

Notes
Oat brands can vary in texture and moisture absorption. Begin with 8 ½ cups of oats and add more as needed to achieve the desired dough texture.
If your mixing bowl is too small, add part of the oats, mix, then transfer the dough to a larger bowl to finish mixing in the remaining oats and mix-ins.
If cookies come out too puffy, a gentle drop or two of the baking sheet onto the counter after removing from the oven can flatten them slightly.
This recipe yields a large batch (about 60 cookies); freezing extras is recommended to keep them fresh.
