Gluten-Free Monster Cookies have become my happy solution whenever I crave something chewy, sweet, and packed with fun flavors yet need a treat safe for all my gluten-free friends. Each bite bursts with peanut butter, oats, chocolate, and candies making them as visually joyful as they are satisfying after school, for dessert, or even snuck during late-night baking sessions.

My first batch disappeared in a flash at a school potluck and I’ve turned to it ever since. The colors and textures lure kids of all ages my family always swipes the cooling cookies before I can move them to the rack.

Instructions

Preheat the Oven:
Get your oven ready at 350 degrees F or 175 degrees C. Line two baking sheets with parchment so nothing sticks and cleanup is easy.
Prepare the Dry Ingredients:
In a medium mixing bowl stir together the oats baking soda and salt. Make sure everything is evenly distributed for an even texture later.
Cream the Peanut Butter and Sugars:
In a large bowl beat the peanut butter brown sugar and granulated sugar until smooth and creamy. Take about 2 minutes with an electric mixer or a sturdy spoon. You want it light and fluffy for tender cookies.
Incorporate Eggs and Vanilla:
Add both eggs and the vanilla extract into the creamy mixture. Mix thoroughly until no streaks remain and the batter looks well-blended.
Combine Wet and Dry Components:
Gradually stir the oat mixture into the wet ingredients just until all oats are moistened. Avoid overmixing to keep cookies soft.
Add the Mix-Ins:
Fold in chocolate chips candy-coated chocolates and chopped peanuts if using. Make sure the goodies are evenly scattered throughout every scoop.
Shape the Cookies:
Scoop out tablespoon-sized balls of dough onto the baking sheets leaving about 2 inches around each. Use your fingers or the back of a spoon to gently pat them into disks for even baking.
Bake to Perfection:
Place the sheets in the oven and bake for 10 to 12 minutes. Watch for edges turning golden while centers remain soft. This is key for chewy cookies.
Cool the Cookies:
Leave baked cookies on the sheet for 5 minutes to firm up then transfer to a wire rack to finish cooling. This keeps them from crumbling while warm.
