Zucchini Monster Cookie Recipe - You would NEVER know these have zucchini in them! They are delicious!! #monstercookies #zucchini #cookies

You know about monster cookies, right? Basically they are oatmeal cookies loaded with all things good! We are a family of cookie monsters and I know so many of you are up to your necks in zucchini right now, so I thought it would be really fun to make cookies with zucchini! Believe me, even if you hate zucchini, you will still love theses cookies! You can’t taste it at all.

Zucchini Monster Cookie Recipe - You would NEVER know these have zucchini in them! They are AMAZING!! #monstercookies #zucchini #cookies

My 3 older kids (5, 2, and 2) helped me make these cookies. I set out all the ingredients on the counter and my daughter (5) flipped out. Do NOT put zucchini in these. I don’t like zucchini!!

I promised her that she would love these cookies despite the fact that they were made with zucchini. She decided to be brave and go along with my crazy idea. Since we were adding a vegetable to these monster cookies, I figured I should try to make them slightly healthier by eliminating the butter as well. Then I crossed my fingers as the cookies baked.

Oh my goodness, you guys! These came out so so good! I honestly mean it when I tell you you would NEVER guess these are made with zucchini and NO butter! They are slightly crisp on the outside with a soft, chewy middle.  I might forever make my monster cookies this way! I shared with a few neighbors and they agreed, these cookies are amazing!

    You are very brave letting the kids see that zucchini was going in. I would have to hide that from them and then maybe, just maybe, tell them after the fact! Great looking recipe!
