Copycat Crumbl Monster Cookie Recipe: Oatmeal Crunch Meets Gooey Chocolate Swirls

This copycat Crumbl Monster cookie recipe delivers the signature oatmeal crunch, gooey chocolate swirls, and caramel drizzle that made the original a cult favorite. After analyzing the bakery’s texture secrets—including the perfect balance of chewy dough and crispy oats—I’ve recreated their signature cookie at home with professional results.

The key lies in precise ingredient ratios and a 335°F baking temperature that ensures a thick, cake-like center with crisp edges.

The dough combines buttery brown sugar, melted butter, and a blend of rolled oats and chocolate chunks for that signature texture contrast. A resting period allows the flour to hydrate fully, preventing cracking during baking.

Once baked to a golden brown, the cookies develop that signature chewy-yet-crispy bite with pockets of molten chocolate swirling through the center. The caramel drizzle ties it all together, adding a sweet, sticky finish that’s impossible to resist.

What sets this recipe apart is the attention to detail in every step—from measuring ingredients to baking times—to ensure your cookies match the bakery’s quality. The result is a cookie that’s thick, chewy, and packed with flavor in every bite, just like the original.

Whether you’re baking for a crowd or treating yourself, this recipe delivers restaurant-quality cookies with a fraction of the cost.

For those looking to customize, you can easily swap out ingredients for vegan alternatives or adjust the chocolate-to-oat ratio. The method remains the same, ensuring consistent results every time. Let’s get baking—your taste buds will thank you.

Ingredients for copycat crumbl monster cookie

Precision ingredients unlock the bakery’s signature texture and flavor in these copycat Monster cookies.

The butter and sugars form the foundation, so use high-quality unsalted butter—none of that margarine nonsense. Bob’s Red Mill rolled oats are my go-to for that perfect chew, but any old-fashioned oats will work. Chocolate chunks should be 1-inch pieces or larger to create those melt-in-your-mouth pockets. For the caramel, Trader Joe’s salted caramel sauce is my secret weapon—it’s perfectly balanced and saves time. If you’re making your own caramel, use heavy cream and brown sugar for depth. The sea salt flakes? Maldon is the gold standard, but any flaky salt will do.

No rolled oats? Substitute quick oats and toast them for 5 minutes to mimic the texture. White chocolate chips can replace half the semi-sweet chunks if you prefer a milder flavor. For a vegan version, use coconut oil instead of butter and flax eggs (1 tbsp ground flax + 3 tbsp water per egg). The baking soda is non-negotiable—it’s what gives these cookies that signature rise. If your chocolate chunks are too small, roughly chop larger bars yourself for consistency. And for the love of cookies, measure your flour by weight if possible—spooning and leveling leads to inconsistent results.

Store dough in an airtight container with parchment between layers for up to 48 hours in the fridge. Baked cookies keep their chew for 5 days in a sealed container at room temperature. For longer storage, freeze dough balls on a tray first, then transfer to a bag for 3 months. Reheat baked cookies in a 300°F oven for 3-5 minutes to restore that bakery-fresh texture. The caramel drizzle hardens at room temperature, so bring cookies to warmth before serving—trust me, it’s worth the extra minute.

Step-by-step instructions for copycat Crumbl Monster cookie recipe

Master the signature texture and flavor with precise technique—oatmeal crunch, caramel swirls, and chocolate pockets every time.

In a stand mixer fitted with the paddle attachment, combine the 1 cup unsalted butter with the 1.25 cups light brown sugar and 0.25 cup granulated sugar. Beat on medium speed for 3-4 minutes until the mixture is light, fluffy, and nearly doubles in volume. This creaming process incorporates air, which creates that signature crackly top and tender crumb.

Add the 2 whole large eggs, one at a time, mixing just until each is fully incorporated after each addition. Scrape down the sides of the bowl to ensure even mixing. Then add the 1 teaspoon vanilla extract and mix for an additional 30 seconds until fully combined. The mixture should be smooth and slightly thickened—this is your foundation for the perfect cookie texture.

In a separate bowl, whisk together the 2.5 cups all-purpose flour, 0.5 teaspoon baking soda, and 0.5 teaspoon diamond crystal kosher salt. Sift the flour mixture directly into the wet ingredients while the mixer runs on low speed. Mix just until the dry ingredients are fully incorporated—you should still see small streaks of flour, but no dry pockets remain.

Remove the bowl from the mixer and gently fold in the 1.5 cups rolled oats, 1.5 cups semi-sweet chocolate chunks, and 0.5 cup white chocolate chips using a silicone spatula. Be careful not to overmix—just combine until evenly distributed. The oats will add that signature crunch, while the chocolate creates pockets of gooey goodness in every bite.

Using a cookie scoop or tablespoon, divide the dough into 12 equal portions (about 2 tablespoons each) and roll them into balls. Place 6 dough balls on a parchment-lined baking sheet, spacing them 2 inches apart. Flatten each ball slightly with your palm to create a ½-inch thick disc.

Take the remaining 6 dough balls and press a ½-inch deep well into the center of each flattened disc. Spoon 1 tablespoon of salted caramel sauce into each well, then use a spoon to gently swirl the caramel into the surrounding dough. This creates those signature caramel pockets that burst with every bite. Repeat with the remaining dough and caramel.

Preheat your oven to 350°F and bake the cookies for 12-14 minutes, or until the edges are golden brown and the tops look slightly cracked. The centers should still appear slightly underdone—they'll firm up as they cool. Rotate the baking sheet halfway through baking for even cooking.

Remove the cookies from the oven and immediately sprinkle each with a pinch of sea salt flakes while they're still warm. This enhances the caramel flavor and adds a delightful contrast. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. The caramel will continue to soften slightly as they cool, creating that perfect gooey texture.

Allow the cookies to cool completely before serving—this ensures the caramel sets properly and the texture is just right. Store any leftovers in an airtight container at room temperature for up to 5 days, though I doubt they'll last that long. Serve warm for the ultimate experience, with a glass of cold milk or a scoop of vanilla ice cream for the full Crumbl effect.

The result should be a cookie with a crispy exterior, a soft and chewy center, pockets of gooey caramel, and chunks of oatmeal and chocolate in every bite. Each cookie should be 3-4 inches wide with a crackly top and a caramel swirl that's visible through the dough. Enjoy immediately for the best texture and flavor.

Make-ahead tips for this copycat crumbl monster cookie

Dough Prep Ahead

Prepare the dough up to 48 hours in advance for maximum flavor development. After mixing all ingredients, portion the dough into 12 equal balls (about 2 tablespoons each) and store them in an airtight container between layers of parchment paper.

This prevents sticking and maintains freshness. I like to label the container with the date—trust me, you’ll want to bake these before they disappear! 🧁

Freeze for Later Baking

For long-term storage, freeze the dough balls on a parchment-lined tray for 1 hour until firm. Transfer them to a sealed freezer bag with parchment between layers to prevent sticking. They’ll keep for up to 3 months.

When ready to bake, let them thaw in the fridge overnight or at room temperature for 1-2 hours before baking. No need to thaw completely—just bake straight from frozen, adding 2-3 extra minutes to the cooking time.

Caramel Swirl Hack

Save time by pre-swirling the caramel into the dough balls before freezing. Press a well into each dough ball, add 1 tablespoon caramel sauce, and swirl it in.

Freeze as directed, and when baking, skip the swirling step entirely. This ensures the caramel stays perfectly centered in every cookie, just like Crumbl’s signature style. 💫

Baked Cookie Storage

Once baked, let cookies cool completely before storing in an airtight container at room temperature for up to 5 days. For best texture, reheat in a 300°F oven for 3-5 minutes to restore that bakery-fresh chew.

Avoid the microwave—it turns the caramel into a sad, melted puddle. If you’re prepping for a crowd, bake half the batch, store them, and enjoy the other half fresh while they’re still warm.

Portion Control

Use a 2-tablespoon cookie scoop (like the OXO Good Grips brand) for consistent dough portions. Over-scooping leads to dense cookies, while under-scooping gives you thin, crispy ones.

Weigh your dough balls for precision—I aim for 40-45 grams each. This ensures every cookie has that perfect balance of chewy center and crispy edges. 💡

Caramel Drizzle Shortcut

Skip the swirling step entirely by drizzling caramel over the top of each cookie after baking. Use a spoon to spread 1 teaspoon of warmed caramel sauce over the center of each cookie while still warm.

Let it set for 10 minutes before serving. This creates a glossy, gooey finish without the fuss of swirling—plus, it’s easier to customize the amount of caramel per cookie.
