For the Base
- Unsalted Butter – Provides richness and tenderness; can substitute with margarine or dairy-free alternatives.
- Brown Sugar – Adds moisture and depth of flavor; feel free to use light or dark brown sugar interchangeably.
- Granulated Sugar – Sweetness and crispness in cookies; you can reduce the amount for a less sweet cookie.
- Vanilla Extract – Enhances overall flavor; opt for pure vanilla extract for the best results.
- Eggs – Bind ingredients together and add structure; you can substitute one egg with flaxseed meal for a vegan option.

For the Dry Mixture

Step‑by‑Step Instructions for Christmas Monster Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C) to ensure it reaches the right temperature. While the oven warms up, prepare a baking sheet by lining it with parchment paper to prevent sticking. This step sets the stage for baking beautiful Christmas Monster Cookies that are evenly cooked.
Step 2: Mix the Wet Ingredients
In a large mixing bowl, use an electric mixer to cream together 1 cup of softened unsalted butter, 1 cup of brown sugar, and 1 cup of granulated sugar until the mixture is light and fluffy, approximately 2-3 minutes. This creaming process incorporates air, which helps the cookies rise beautifully, making them soft and chewy.
Step 3: Add Flavor Enhancers
Pour in 1 tablespoon of vanilla extract and mix well until fully incorporated. Then, add 2 large eggs and 1 additional egg yolk, blending them in one at a time. Each addition should be mixed thoroughly before adding the next, creating a smooth batter full of flavor for your Christmas Monster Cookies.
Step 4: Combine the Dry Ingredients
In a separate bowl, whisk together 3 cups of all-purpose flour, 1 teaspoon of baking soda, 1 teaspoon of baking powder, and ½ teaspoon of salt. Gradually add this dry mixture to your wet ingredients while mixing on low speed. Stir until just combined to avoid overmixing, ensuring your cookies will remain tender.
Step 5: Fold in the Fun Additions
Gently fold in 2 cups of old-fashioned oats, 1 cup of Christmas M&Ms, 1 cup of crushed pretzels, ½ cup of semi-sweet chocolate chips, and ½ cup of white chocolate chips. Be careful not to overwork the dough; you want the mix-ins to be evenly distributed without compromising the cookie’s texture, resulting in delightful Christmas Monster Cookies.
Step 6: Shape the Cookies
Using your hands, roll the dough into uniform 2-inch balls, placing them 2 inches apart on the prepared baking sheet. For an extra festive touch, press additional Christmas M&Ms onto the top of each dough ball. This adds a pop of color and ensures everyone sees the delightful mix-ins.
Step 7: Bake the Cookies
Slide the baking sheet into your preheated oven and bake the cookies for 8 minutes. After that, carefully rotate the sheet and bake for an additional 4-5 minutes until the edges turn lightly golden. The centers should look slightly underbaked; they will continue to firm up as they cool, producing perfect Christmas Monster Cookies.
Step 8: Cool and Serve
Once baked, transfer the cookies to a cooling rack and allow them to cool for about 5 minutes on the sheet before moving them. This lets the cookies set up nicely while still warm. Once ready, serve your delicious Christmas Monster Cookies and watch them disappear, bringing holiday joy to all!

Storage Tips for Christmas Monster Cookies
Room Temperature: Store cookies in an airtight container at room temperature for up to 1 week to maintain their softness and freshness.
Fridge: For longer storage, you can place the cookies in the fridge for up to 2 weeks. Ensure they are well-wrapped to prevent drying out.
Freezer: Freeze cookies in a single layer on a baking sheet, then transfer to an airtight freezer bag for up to 3 months. Thaw and enjoy a delightful treat whenever you wish.
Reheating: To revive the cookies, pop them in the microwave for about 10-15 seconds. This will soften them, making the experience of biting into a warm Christmas Monster Cookie even more enjoyable!

Christmas Monster Cookies Recipe FAQs
What type of pretzels should I use for the cookies?
I recommend using traditional pretzel sticks as they provide the perfect crunch that complements the sweetness of the cookies. However, feel free to experiment with crushed pretzel chips or even flavored pretzels to add a unique twist!
How long can I store Christmas Monster Cookies?
You can store your cookies in an airtight container at room temperature for up to 1 week. Make sure they are sealed well to maintain their soft and chewy texture!
Can I freeze the cookie dough for later use?
Absolutely! To freeze the cookie dough, roll it into uniform 2-inch balls and place them on a baking sheet, ensuring they don’t touch each other. Freeze until solid, then transfer the dough balls into a freezer bag. They can be stored for up to 3 months. When you’re ready to bake, just pop them in the oven directly from the freezer, adjusting the bake time slightly.
What should I do if my cookies turn out too flat?
If your Christmas Monster Cookies spread too much during baking, check a few factors like the temperature of your butter or not using enough flour. Ensure your butter is soft but not melted, and if you think the dough is too wet, try adding a little extra flour, about a tablespoon at a time, until the right consistency is achieved.
Is there a way to make these cookies healthier?
Certainly! You can make some substitutions to healthify your Christmas Monster Cookies. Consider using whole wheat flour instead of all-purpose flour for a fiber boost, and swap out some of the sugar for mashed bananas or applesauce for natural sweetness. You can also add in nuts or seeds for extra nutrients.
Can I customize the mix-ins for my Christmas Monster Cookies?
The more the merrier! Feel free to get creative with your mix-ins. You can use chopped nuts, dried fruit, or even swap the semi-sweet chocolate for dark chocolate. Just keep the total amount of mix-ins similar to what’s in the recipe to maintain the right texture!
