What’s In This Crumbl Monster Cookie Recipe?

See the recipe card below for a complete list of ingredients and measurements.

• Unsalted sweet cream butter: This is the foundation of our cookie’s rich flavor. Make sure it’s softened to room temperature for easy mixing, and use unsalted to control the salt content in the recipe.
• Light brown sugar: This ingredient adds moisture and a subtle molasses flavor to the cookies. When measuring, be sure to pack it firmly into the cup to get the right amount.
• Eggs: Large eggs are the standard for baking and provide structure to the cookies. They also help bind the ingredients together.
• Pure vanilla extract: This adds depth and enhances the overall flavor of the cookies. Always opt for pure vanilla extract rather than imitation for the best taste.
• Flour: All-purpose flour is the go-to choice for most cookie recipes. It provides the structure and helps hold all the ingredients together.
• Cornstarch: This secret ingredient helps create a tender, soft texture in the cookies. It also helps prevent the cookies from spreading too much during baking.
• Baking powder: This leavening agent helps the cookies rise and creates a light, fluffy texture. Make sure it’s fresh for the best results.
• Kosher salt: Salt enhances all the flavors in the cookie. If you’re using salted butter, you may want to reduce or omit this ingredient.
• Mini chocolate chips: These add bursts of chocolate flavor throughout the cookie. You can use semi-sweet or milk chocolate chips based on your preference.
• Chocolate chip cookies, crushed: This adds texture and an extra layer of cookie flavor. Make sure to crush them into small pieces for even distribution.
• Powdered sugar: Also known as confectioner’s sugar, this fine sugar creates a smooth, creamy frosting. It dissolves easily, preventing a grainy texture.
• Heavy whipping cream: This adds richness to the frosting and helps achieve the right consistency. It also gives the frosting a luxurious mouthfeel.
• Sky blue gel food color: Gel food coloring is more concentrated than liquid, allowing you to achieve vibrant colors without affecting the frosting’s consistency.
• Mini chocolate chip cookies: These are used as a decorative topping, adding an extra crunch and visual appeal to the finished cookies.
• Crushed cookies: These cookie crumbles add texture and flavor to the top of the frosted cookies, enhancing the overall “monster” look.

Substitutions and Additions

• Gluten-free flour blend: Substitute all-purpose flour with a 1:1 gluten-free flour blend for a gluten-free version.
• Coconut sugar: Replace brown sugar with coconut sugar for a slightly different flavor profile and lower glycemic index.
• Vegan butter: Use vegan butter sticks instead of regular butter for a dairy-free option.
• Flax eggs: Replace each egg with 1 tablespoon ground flaxseed mixed with 3 tablespoons water for a vegan version.
• White chocolate chips: Swap mini chocolate chips for white chocolate chips for a sweeter, creamier taste.
• Peanut butter chips: Add 1/2 cup of peanut butter chips to the dough for a nutty flavor twist.
• Crushed Oreos: Use crushed Oreos instead of regular chocolate chip cookies for a cookies-and-cream variation.
• Cream cheese frosting: Replace the vanilla frosting with cream cheese frosting for a tangier flavor.
• Food coloring options: Experiment with different food coloring to create various “monster” colors like green, purple, or pink.
• Candy eyes: Add edible candy eyes on top of the frosting for a more playful monster look.

How to Make Blue Crumbl Monster Cookies (step-by-step directions)

1. Begin by preheating your oven to 350°F (175°C) and preparing your baking sheets with parchment paper or silicone mats.
2. In a stand mixer, combine the brown sugar, softened butter, eggs, and vanilla. Mix until you achieve a smooth, fluffy consistency.
3. In a separate bowl, whisk together the dry ingredients: flour, cornstarch, baking powder, and salt. Gradually incorporate this mixture into the wet ingredients, mixing until a cohesive dough forms.
4. Gently fold the mini chocolate chips and crushed cookies into the dough (Photo 1).
5. Using a medium ice cream scoop, portion out the dough and roll each portion into a ball (Photo 2). For consistency, aim for each ball to weigh about 2.5 oz.
6. Place the dough balls on your prepared baking sheets and bake for 13-16 minutes, or until the edges are lightly golden.
7. Once baked, remove the cookies from the oven and allow them to cool completely on the baking sheet (Photo 3).
8. For the frosting, use your stand mixer to beat together the butter, powdered sugar, vanilla, and heavy whipping cream until smooth and able to hold its shape.
9. Incorporate a few drops of sky blue gel food coloring into the frosting, mixing until you achieve your desired shade of blue.
10. Transfer the frosting to piping bags for easy application.
11. To decorate, start at the center of each cooled cookie and pipe a thick ring of frosting to the edge. Sprinkle crushed cookies over the frosting, and finish by placing a mini cookie in the center (Photo 4).

Recipe Tips

• Chill the dough for 30 minutes before baking to prevent excessive spreading.
• Use a light-colored baking sheet to prevent the bottoms from browning too quickly.
• For perfectly round cookies, use a large round cookie cutter to gently shape them immediately after removing from the oven.
• Allow the cookies to cool completely before frosting to prevent the frosting from melting.
• If the frosting is too thick, add a little more heavy cream. If it’s too thin, add more powdered sugar.
• For a smoother frosting application, use a rotating cake stand while piping.
• To achieve a professional look, use a piping bag fitted with a large star tip for the frosting.
• Experiment with different sizes of mini cookies for topping to find your perfect look.
• If you don’t have piping bags, you can use a zip-top bag with a corner snipped off.
• For a more intense cookie flavor, try toasting the crushed cookies before adding them to the dough and topping.

Storing Tips

For the best results, store these delicious cookies in an airtight container. They can be kept at room temperature on in the fridge for up to 3 days.
