How to Make Cookie Monster Cookies
Ready to make the best monster cookie recipe? It’s a breeze! To get started, preheat your oven to 350°F, grab your cookie scoop and baking sheet, gather all your ingredients, and follow along:
- Step 1: Brown the Butter. Brown the butter over medium heat in a frying pan. Stir the butter occasionally until it turns an amber color. Remove the pan from the heat as soon as the butter starts to brown, pour into a medium bowl, and set aside to cool.
- Step 2: Combine the Wet Ingredients. Beat the brown sugar, granulated sugar, egg, egg yolk, vanilla, and sour cream until they are well combined.
- Step 3: Combine the Dry Ingredients. Whisk the flour, baking soda and salt together in a medium bowl.
- Step 4: Make the Blue Cookie Dough. Gradually mix the dry ingredients into the wet ingredients on low until just combined, and then, add a few drops of blue food coloring until you achieve your desired color.
- Step 5: Add Chocolate and Chill. Stir the milk and white chocolate chips into the dough, cover with plastic wrap and chill for 1 hour.
- Step 6: Turn it into Monster Cookie Dough. Scoop and roll the cookie dough using a 1-inch cookie scoop and place each one on the un-greased baking sheet. Then top each cookie with mini chocolate candies and coarsely chopped Oreos.
- Step 7: Bake and Cool. Bake the cookies for 10-11 minutes until the edges start to brown. Then, remove the pan from the oven and let the cookies rest in the pan for 5 minutes before moving them to a wire rack to cool completely.

Recipe FAQs
The dough for these cookies should be chilled before baking to slow their spread as they bake. If not, the cookie dough will spread far too much.
Browning butter for cookies is totally optional. Browning the butter adds a slightly nutty flavor and makes for chewier cookies.
This cookie dough can be frozen for up to 1 month. Make sure to stack the cookies with parchment paper in between and place them in a freezer-safe bag. Thaw at room temperature or heat them in the oven for that freshly baked texture.
Absolutely! If you prefer, you can skip the blue food coloring. The cookies will still be delicious and have all the same tasty mix-ins—just without the signature blue hue.

Cookie Monster Cookies
Ingredients
- 1 cup butter
- 1 ½ cups brown sugar, packed
- ¼ cup granulated sugar

- ½ teaspoon salt
- Few drops blue food coloring
- 1 cup milk chocolate chips
- 1 cup white chocolate chips

Instructions

- Beat brown sugar, granulated sugar, egg, egg yolk, vanilla and sour cream with the browned butter until combined.
- In a medium bowl, whisk flour, baking soda and salt together.

Notes
- If you’re looking to save some time, you can skip making the browned butter if you want (but I encourage you not to), but not the step for chilling the dough. If you don’t chill, the cookie dough will spread far too much.
- You can make the dough ahead of time! Chill it in the refrigerator for up to 24 hours, or freeze it for up to 1 month. If frozen, let the dough thaw overnight in the fridge before baking as usual.
- Keep a close eye on the butter when it’s browning so it doesn’t burn.
