this recipe &t.constructor;&t;

I’m a cookie fiend &#e since I posted them earlier this year, and I’m here to share a favorite twist on that recipe!!

Have you ever had a monster cookie? Usually XXL in size, and loaded with oats, peanut butter, and M&M candies for a colorful, delightful cookie that is as cute as it is delicious! These Monster Cookie Bars are a gluten-free and vegan take on that classic cookie, and they’re even easier to make — and way more wholesome! Let’s get into what you need to make them:

Peanut Butter: this is the most classic nut butter for monster cookie flavor, but you can use any you’d like — even a seed butter to keep it nut-free!
Coconut Oil: this is our fat for the recipe. You can substitute vegan butter or regular butter if you eat dairy.
Coconut Sugar: my favorite sweetener! Adds a nice subtle sweetness to the recipe.
Flax Egg: a regular egg could also be used if preferred,
Vanilla Extract: for flavor!
Oat Flour: make sure to use gluten-free oat flour if you’re strictly gluten-free. You can also use almond flour.
Rolled Oats: like above, make sure to use gluten-free if needed!
Baking Soda & Salt
Dark Chocolate Chips: chunks or chips will both work here.
Peanut Chocoalte Candies: I used the dark chocolate peanut gems from Unreal Snacks, which don’t use artificial colors like classic M&M’s.

Mix together the peanut butter, coconut oil, and coconut sugar. Once combined, stir in the flax egg and vanilla.
Stir in the flour, oats, baking soda, and salt. Mix until a dough forms.
Fold in the dark chocolate chips and dark chocolate peanut candies.
Press into an 8×8″ pan and bake for 18 minutes until browned on the edges but not overcooked in the center.
Cool, cut, serve, and enjoy!!

Tips to make ahead of time:

These monster cookie bars freeze quite well, so they’re perfect for making ahead of time if you need to!

How to store: I find these store best in an airtight container. They stayed fresh on the counter for 5 days. In the refrigerator, they should keep well for up to a week.

To freeze: I recommend placing them in an airtight container with parchment separating each layer to prevent them from sticking together. They will keep for at least 3 months.
