Monster Cookies (Gluten Free & Nut Free)

Monster Cookies are incredibly delicious cookies to make and are normally made with peanut butter. This nut allergy-friendly cookie is made with peanut-free peanut butter and they’re gluten-free!

Nut Free Cookies

Monster cookies are traditionally made with peanut butter. These cookies were a staple in my home during the holidays when I was a child. We enjoyed eating these cookies but we really enjoyed making them together and baking them in the Christmas season.

Fast forward, baking cookies is something that I enjoy with my children. When it comes to baking with tree nuts or peanuts with my son, it’s a no go. He is allergic to a variety of nuts as well as peanuts. Whenever I made monster cookies I would also make a nut-free cookie for him but he always wanted to try the ones that I made with my mother.

I decided to make a nut-free version of my mother’s recipe that has been handed down and it turns out that the peanut butter can be switched out with a 1:1 ratio to peanut-free peanut butter.

I have to tell you, these cookies taste just as delicious as making them with real peanut butter. In fact, I couldn’t even tell a difference in flavor or texture!

What’s In a Monster Cookie?

Monster cookies are gluten-free making them a great option for those with gluten sensitivities. They are made with old-fashioned oats (make sure to get gluten-free certified oats if you’re making them gluten-free!), peanut-free peanut butter, chocolate chips (gluten-free varieties are available) as well as M&M’s.

These cookies are incredibly easy to make and once they bake they turn into large size-of-your-hand cookies.

Easy to Make Cookies

These cookies are incredibly simple to make and it’s a great recipe to get kids hands-on in the kitchen. It’s also great for beginner bakers! These cookies don’t take a lot of effort to make and they’re flourless so there’s no worrying about if they’re going to come out correctly or not.

To make these cookies even easier to make, I use silicone mats placed on my baking sheets. Silicone mats are nonstick and super easy to clean up.

I also use a cookie scoop to get my cookies all the same time. It’s an easy way to get them the same size.

I thought M&Ms where not safe for peanut allergies.. has this changed?

M&M's are made in a plant that processes peanuts so it depends on the peanut allergy. My child has peanut and tree nut allergies but is able to eat foods that are processed in the plant but that's definitely not the case for everyone! The M&M's can be substituted for chocolate chips that are nut-free such as the Enjoy Life Brand. As always, keep reading those labels when making a decision on consuming foods with a possible allergy contaminant! :)
