Gluten Free Monster Cookies

Monster Cookies are one of my favorite treats. I needed a dessert for Brandon’s fantasy football draft and wanted to make something that I could eat too. It’s no fun to bake something and not be able to sample it!

I started researching different types of monster cookie recipes. After sifting through numerous gluten-filled and gluten free options…I came up with this recipe. These cookies are chewy, loaded with oats and chocolate, and the batter makes 5 dozen cookies…perfect for a crowd!

Start by creaming the butter and sugars.


Add the eggs, salt, and vanilla, Mix well. Add the peanut butter and mix well. Combine the flour, baking soda, and baking powder. Mix into the wet ingredients.


Scrape the sides of the bowl. Mix in the oats and cinnamon. When that is combined, mix in the M & Ms and mini chocolate chips.


Using a 1.5 inch scoop, drop cookies onto sheet trays, a dozen at a time.


Bake at 350 degrees for 12 minutes.


Allow the cookies to cool on racks before plating them.


Serve and enjoy!!
