How to Make Gluten Free Flourless Monster Cookies
Step 1: Preheat the Oven
Preheat your oven to 350 degrees Fahrenheit. This ensures that your cookies bake evenly.
Step 2: Prepare the Baking Sheet
Line a baking sheet with parchment paper. This will prevent the cookies from sticking and make cleanup easier.
Step 3: Cream Butter and Sugars
In a mixing bowl, add the softened butter along with both sugars. Use an electric mixer to beat them together for about one minute until smooth.
Step 4: Add Peanut Butter and Eggs
Add in the peanut butter, egg, egg yolk, and vanilla extract. Beat again for an additional 30 seconds until well combined.
Step 5: Mix Dry Ingredients
Incorporate the gluten free quick oats, baking soda, and salt into the mixture. Stir until everything is evenly mixed.
Step 6: Fold in Chocolate Chips and M&Ms
Gently fold in the chocolate chips and mini M&Ms until they are nicely distributed throughout the dough.
Step 7: Scoop Dough onto Baking Sheet
Using a 2 tablespoon cookie scoop, portion out balls of dough onto your prepared baking sheet. Press down slightly to ensure all ingredients stick together.
Step 8: Bake Your Cookies
Bake in your preheated oven for about 9–12 minutes. Keep an eye on them; they should look set but still soft when you take them out.

How to Perfect Gluten Free Flourless Monster Cookies
Perfecting your gluten free flourless monster cookies is easy with just a few tips. Follow these handy suggestions for the best results.
- Use room temperature ingredients: Allowing butter and eggs to warm up helps create a smoother batter and contributes to better texture.
- Measure oats correctly: Too many oats can make the cookies dry; use precise measurements for optimal softness.
- Don’t skip chilling: If you find the dough too sticky, chill it in the fridge for 30 minutes before baking for easier handling.
- Check baking time carefully: Keep an eye on them as they bake, and pull them out when they look set but still soft; they’ll firm up as they cool.
- Add variety: Experiment with mix-ins like nuts or dried fruits to customize your monster cookies further.

Common Mistakes to Avoid
When making these gluten free flourless monster cookies, avoiding common pitfalls can help ensure your cookies turn out perfectly every time.
- Boldly skip the chilling: Many cookie recipes suggest chilling the dough, but for these cookies, it’s better to bake them right after mixing. Chilling can lead to denser cookies.
- Boldly ignore measurements: Accurate measuring of ingredients is crucial. Use standard measuring cups and spoons for precision, especially with peanut butter and sugars.
- Boldly overbake: It’s tempting to leave cookies in a bit longer for extra firmness. Remember, they will continue to firm up as they cool, so take them out just before they look fully set.
- Boldly rush mixing: Take your time when mixing the dough. Ensure the ingredients are well combined for a consistent texture and flavor throughout the cookies.
- Boldly forget to line the baking sheet: Always line your baking sheet with parchment paper. This prevents sticking and helps maintain the shape of your cookies.
