These oatmeal monster bars are perfect for celebrating anything – a birthday, a promotion, or even a day on the couch. They’re fun to make, so tasty and gluten free. The bars are similar to oatmeal cookies, but baked like brownies and cut into squares. There are no refined sugars in these either, so you can feel good about sharing them with friends and family for a healthier option.

Oatmeal Monster Bar Ingredients
Coconut Oil: The main liquid component of the oatmeal bars is melted coconut oil. I use coconut oil for almost all of my dessert recipes because it works well for so many textures. You won’t get any coconut flavor, so don’t worry if that’s not your thing! If you’re looking for a substitute, melted ghee or olive oil will work.
Coconut Sugar: The oatmeal bars are sweetened mainly by coconut sugar. You could also use date sugar, but I don’t recommend maple syrup or honey because the consistency will likely be off. You can find coconut sugar at pretty much any grocery store, but brown sugar is a substitute as well.
Eggs: You’ll need two eggs for this recipe, which help to bind the ingredients together while they bake. I have not tried this recipe with flax or chia eggs, so I can’t speak to vegan options. The eggs are key to the success of the bars baking correctly.
Oat Flour: As I mention in the instructions for the recipe, you can either buy oat flour at the grocery store or make it yourself by blending a cup of gluten free oats in a high-speed blender. I always just make it myself to make things easier! It’s up to you.
Oats: I recommend using any brand of gluten-free rolled oats for this recipe. I usually order them from Thrive Market, but you can find them at any grocery store. I don’t recommend substituting the oats but you can of course use non-gluten-free oats if you don’t have an allergy.
M&Ms or Dairy-Free Candies: I’ve recently discovered Unreal Milk Chocolate Gems and I’m obsessed. Honestly, they were what inspired me to make this recipe! They’re my favorite, but you can use regular M&Ms if you don’t have a preference or any other candy. Dairy-free chocolate chips would work great here as well.

How To Make Oatmeal Monster Bars
Step One: Preheat oven to 350 degrees and line a 9×9 baking dish with parchment paper.
Step Two: In a large mixing bowl, combine the melted coconut oil and coconut sugar by quickly whisking it together. Add the vanilla extract and eggs, then whisk again to combine.
Step Three: Blend one cup of oats in a high-speed blender to make oat flour, or use store bought oat flour. Add the oat flour, oats, baking powder and salt to the bowl of wet ingredients.

Step Four: Mix the wet and dry ingredients until just combined, then fold in the M&Ms, setting some aside to use for topping.
Step Five: Transfer the mix into the baking dish lined with parchment paper and press down to evenly distribute the mix in the pan. Top with extra M&Ms if desired.
Step Six: Bake for 18 to 22 minutes, until the oats are beginning to brown on the edges. Let cool completely before pulling out the parchment paper and slicing into nine even bars. Store in the refrigerator for up to five days.
