This Monster Cookie recipe has been tucked away in my recipe stash for years. You’ll find that this cookie is easy to make and your people will gobble them up.
My memory is a little fuzzy on where I originally got this recipe. I think I snagged it at my friend, Jeanna’s wedding shower many years ago. She might be scratching her head as she reads this and text me to tell me I’m cray. I blame the mom brain.
While I’d love to give proper credit to the originator of this recipe, Jesus knows who you are. I don’t. God bless you for sharing it with me so I can share it with the world.
Because guys, these cookies are good.
What’s in Monster Cookies?
What’s interesting to me about these Monster Cookies is that there is no flour in the recipe. Nada. Just a lot of oats, peanut butter, and sugar. Shocker, I know.
It’s a super simple recipe to make too. Just mix together all of the ingredients minus the chunky stuff.
What’s the chunky stuff I’m referring to? Oh you know, just all the things good in the world. See below.
After that, stir in 4.5 cups of oats. Not a typo. Lots of oats. Probably why the recipe can get away with no flour.
Stir it up.
Try not to eat.
At least too much.
Think: 3 raw eggs in this mix.
As if that’s ever stopped me before.
I found that using a 1/4 measuring cup to scoop these out on a sheet was about right. Plop them on there and don’t worry about squishing them down. They’ll mellow out on their own.
How Long do I Bake Monster Cookies?
Now here is the key to taking these to the next level. Only bake them for 10-12 minutes. At 12 minutes you are going to think, “These don’t look done. That blogger is wrong. I need to cook these longer.”
Wrong wrong wrong.
Take them out!
BUT. You must let them cool down at least 30 minutes. If you try too early, they will fall apart and you will send curses my way. Patience, my friend.
How Long do Monster Cookies Last?
Another thing I love about these Monster cookies is that they don’t dry out very quickly. You know how most cookies the next day are just, meh. Not so with these beauties. They stay moist and will beckon to you night and day for a good 2 days.
Are Monster Cookies Gluten Free?
If you try to avoid gluten in your diet, here’s the good news: Monster Cookies have a great gluten free option!
The only ingredient has gluten is the oats. If you use gluten free oats, these cookies are gluten free!Print
