“What are monster cookies, though?” I asked recently, with vague recollections of cookies with M&M’s in them. “Peanut butter, chocolate, and oat cookies.” “Well, I’m sold.”

This monster cookie recipe took me about eight tries (nine?) to get right, but they are just right. I almost gave up on them, to tell you the truth. My fella took a batch to work and overheard his coworker say, “This is the best cookie I’ve ever had,” so I knew I was close. Here they are, in time for a fun weekend baking project or holiday treat. Let’s make some cookies!

These monster cookies are made with more wholesome ingredients than most. They have a classic bakery look and taste, and the sugar content that goes along with that. (If you’re looking for lightened-up, lower-sugar cookies, check these out, or just make half-sized cookies.) These cookies are essentially made with peanut butter, eggs, coconut sugar or brown sugar, melted coconut oil or butter, and chocolate. They’re flourless and gluten free, as long as your oats are certified gluten free. I like to think that the nut butter and oats make them a little more redeeming.

How to Make Monster Cookies

These cookies are seriously easy to make with basic ingredients. You don’t even need to remember to soften your butter! Here’s the rundown:

Quick-cooking oats vs. old-fashioned oats

Quick oats disappear more into the cookies, whereas old-fashioned oats offer a more hearty and discernible texture. Did you know that quick-cooking and old-fashioned oats have nearly identical nutrition properties? Quick-cooking oats are just cut up a little more.

Coconut oil (and other oils) vs. butter

I love using unrefined (virgin) coconut oil in this recipe because it lends a very subtle layer of complexity. I can’t really pick out the coconut flavor, but the cookies taste a little more interesting. You could use a mild extra-virgin olive oil (like California Olive Ranch Everyday) or neutral oil, such as sunflower seed oil, but those tend to be more refined. Butter works great, too, if you’re going for a super classic monster cookie.

Coconut sugar vs. brown sugar

I like to use coconut sugar since it’s a less refined, more natural sweetener made from evaporated coconut nectar. It doesn’t taste like coconut; it’s similar to brown sugar in flavor. It has been gaining popularity over the past few years. I buy it at Trader Joe’s or Whole Foods. Brown sugar works, too, and costs less. You might be wondering why the recipe calls for 2 1/2 cups coconut sugar or 2 cups brown sugar—they actually are about the same by weight. Coconut sugar just weighs less per cup.

Chocolate chips vs. chocolate-coated candies

Most monster cookies are made with an equal mix of chocolate chips and chocolate-coated candies (think M&M’s). The candies are fun because you can buy colors that match the seasons or holidays (red and pink for Valentine’s Day, pastels for Easter, red and green for Christmas, multi-colored for Halloween, etc.). I bought my naturally colored candies at Whole Foods, near the bulk bins. However, I also love these cookies with all chocolate chips. I buy bittersweet chocolate chips, so they satisfy my craving for dark chocolate that way.

Change It Up

Mix up your mix-ins.

Like I said, I love these cookies with all chocolate chips (no candy-coated chocolate). You could even substitute some chopped nuts, raisins or other dried fruit for some or all of the chocolate.

Substitute other nut butters.

I can’t get enough of the peanut butter version, but you could substitute almond butter or sunflower seed butter.

Make smaller cookies.

This recipe yields 18 large cookies, which use 1/4 cup dough each. You could easily make 36 smaller cookies by using scoops of 2 tablespoons each. You cookies will bake up faster, somewhere between 6 to 9 minutes. They’re done when they’re just starting to turn golden around the edges.

Please let me know how your cookies turn out in the comments! They’re a real treat and I hope they become your new favorite cookie recipe. Looking for more chocolate cookies and desserts?
