Old Fashioned Oats vs. Quick Oats
Either type of oats can be used for this monster cookie recipe, it really just depends on what type of texture you would like. The old fashioned oats will add more texture and will be more noticeable in the cookie. If you want a smoother texture, then go with the quick oats.
How to Make Monster Cookies
Before you get started, set out the butter for a thirty minutes or so, so that it will be close to room temperature. It’s best to use unsalted butter for these monster cookies, since there will be salt added towards the end.
To begin making the monster cookies, mix the softened butter and both sugars together. Next, add in the egg, peanut butter, and vanilla and mix well.
After that, combine the oat flour, oats, baking soda, and salt in a separate bowl. You can easily make your own oat flour by putting oats in the food processor until it is the consistency of flour.
Lastly, combine the wet and dry ingredients together until just combined and then mix in the 3 types of candy.
Now it’s time to get those monster cookies in the oven! Preheat the oven to 350 degrees and bake for 8-11 minutes. The cookies should still be soft in the middle and just slightly browned on the bottom.
