Monster Cookies
Monster cookies are creamy, sweet, nutty goodness of peanut butter. All combined with the richness of oats that gets to me every time.
And when you have things like butterscotch chips, mini M&M’s and of course coconut (which by the way is totally optional for all you coconut haters out there), you get a completely satisfying and tasty cookie!
Monster Cookies are scarily delicious. A funny pun since they are monster cookies!
But they are monsters because of all the mouth wateringly delicious little tid bits I throw into them to make them so darn good.
We love cookies and healthy ones are even better! Try these No Bake Cookies, Matcha Shortbread Cookies, Grab and Go Breakfast Cookies or Apple Pie Breakfast Cookies are quick and easy recipes that are healthy-ish when baking up a sweet treat!
One of the things I absolutely love in a cookie is something that whips up fast, cooks fast, and cleans up fast.
My kids are not going to wait 25 minutes for a cookie to bake, which is why these 10 minute bake-time cookies are a big win at my house.
I baked up a batch just to take with me on a trip overseas, so I will let you know how they fare across the pond.
This recipe makes about 4 dozen cookies. I love peanut butter and oats, and tried to make the combo healthy by making peanut butter banana oat muffins, but for these cookies, I threw the healthy factor out the window and just went for flavor. Success!
What makes a monster cookie?
- Everything is just bigger, tastier and better!
- No need to chill the dough or wait. Because you know your monsters are waiting them!
- Extra big, thick and rich!
- Soft and chewy even though they are oversized monster cookies.
Why quick oats?
Quick oats holds together the cookies and has a consistency that is soft and subtle. They are thiner and finely cut that gives a smooth texture that is natural looking.
If you do not have quick oats, you can use whole oats. Use your food processor or blender to break them into smaller oats.

Thank you! I first tried them with marshmallows…big fail. I always forget they melt and then are hard as rocks. Haha, but now that I have perfected the recipe we can’t stop eating them.
