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 prevents sticking and makes cleanup easier.
Step 3: Mix the Butter and Sugars
In a mixing bowl, add the softened butter along with both sugars. Beat together with an electric mixer for about 1 minute until well combined.
Step 4: Add Peanut Butter Mixture
To the mixture, add in the peanut butter, egg, egg yolk, and vanilla. Beat for an additional 30 seconds until everything is mixed thoroughly.
Step 5: Incorporate Dry Ingredients
Add the gluten free quick oats, baking soda, and salt into the bowl. Mix together until fully combined.
Step 6: Fold in Chocolate Chips and M&Ms
Gently fold in the chocolate chips and mini M&Ms. Ensure they are evenly distributed throughout the dough.
Step 7: Scoop Cookie Dough
Using a 2 tablespoon cookie scoop, portion out the dough into balls. Smoosh all ingredients together to ensure an even mix of chocolate chips and M&Ms.
Step 8: Bake Cookies
Place the cookie dough balls on your prepared baking sheet. Make sure not to overcrowd; bake no more than 9 cookies per sheet at a time. Bake for 9–12 minutes until they look set but still soft.

Common Mistakes to Avoid
Making gluten free flourless monster cookies can be simple, but there are common mistakes that can affect the final outcome. Here are some pitfalls to watch out for.
- Bold Ingredients Measurement: Not measuring ingredients accurately can lead to cookies that are too dry or too wet. Always use precise measurements for the best results.

- Bold Ignoring Oven Temperature: Baking at the wrong temperature can cause unevenly baked cookies. Always preheat your oven properly before baking.
