The Method for Making Monster Cookies:

  1. Preheat the oven to 350 F
  2. Gather all your ingredients and get them ready to mix up.
  4. Add in your PEANUT BUTTER, and combine.
  5. Crack in your EGGS one at a time.
  6. Pour in your VANILLA and mix until smooth and combined.
  7. Once your cookie batter is smooth and fluffy, add in your QUICK OATS, and mix until combined.
  8. Sprinkle in your Baking Soda, now. I always tend to forget this and put it in at the end, but as long as it’s in there, you are good!
  9. Now it’s time to add in your extra treats, this is up to you on what you have in your cupboard. You can omit some of the ones we used if you would rather, but we found this blend was a really nice balance. Add them all in at once, or one by one, and mix up!
  10. Mix, mix, mix.
  11. Take your tablespoon, or scooper out and place your cookies on a lined cookie sheet, we love this cookie liner, the cookies always come off the sheet clean. This set is also a great deal. Place the cookies two per row, to allow for optimum baking space as they melt down nicely.
  12. Bake for 10-12 minutes, depending on how you like your cookies, and how large of a spoonful you used. Test it out. 10 minutes was the perfect time for us, and the size of the scoop we used.
  13. This batch is very large and produces about 50 cookies, so you can also freeze the rest. I like to scoop them all out, and then freeze them on a tray, for a few hours, and once they are frozen, simply place them in a freezer bag, and keep frozen until you want to make another batch of yummy monster cookies!
