These Gluten Free Monster Cookies are thick, packed with goodies, and full of peanut butter. They will sure to become a favorite. Dairy free option. Great for holiday parties or simple events with the kids, this is a great recipe to make with loved ones and has a 10 minute prep!
If you don’t know what a Monster Cookie is, allow me to explain: a sweet peanut butter cookie dough with oatmeal then add in some M&M's and chocolate chips, but feel free to be creative. I did a batch with dried cranberries that my boyfriend loved! I like using crunchy peanut butter for added crunch, but chopped nuts would also be delicious!
Here are the all the ingredients you'll need.
Ingredients
- Peanut Butter – you do not want to use all natural for this recipe. In general, all natural peanut butter in baking just does not work. Use a brand like Skippy or Jif for the best result.
- Butter – salted is best as there is none called for in the recipe. Butter is recommended over margarine for the best result. Make sure that you’ve allowed the butter to come to room temperature to mix best with the sugar and eggs. To make them dairy free, ghee could be used instead.
- Sugar- a mixture of white and brown sugar are used for the best taste and consistency.
- Eggs – these help hold the cookies together. Room temperature is best. If you are pulling your eggs from the refrigerator right before baking, place the eggs in a cup of warm water for a few minutes to take the chill off.
- Gluten Free Oats – I prefer Old-Fashioned Oats for these monster cookies. If you don't need them to be gluten free then use any brand of oats.
- Add ins – get creative here! Chocolate chips, peanut butter chips, toffee pieces – the options are endless! Double check ingredients if you need them to stay gluten free. Dairy free chocolate chips can be used if making them dairy free as well.

Substitutions & Additions
These are already gluten free, but easily made dairy free as well.
Using ghee in place of the butter, a 1:1 ratio. Coconut oil would also work. Instead of M&M's which are milk chocolate, use a dairy free chocolate candy like Unreal.
These two swaps will make them dairy free.
Step-by-Step Directions:
The process is simple, no mixer is needed and they come together quickly. Mix the butter and sugar together and then add in the eggs.
Add in the oats, chocolate chips and candies and stir well. Scoop out and bake- that's it!

Hi- over 95% of my recipes on my site are naturally sweetened. This one recipe, I made for friends and family and got such great feedback that I knew I had to share it here. It's still gluten free with a dairy free option. If you don't want to make them, that's fine. There are lots of recipes that you can make with less sugar. I will share recipes I'm currently making and are special to me.
