How to Make Christmas Monster Cookies Recipe

Step 1: Preheat & Prepare

Start by preheating your oven to 350°F and lining your baking sheets with parchment paper. This prep ensures that your cookies bake evenly and come off effortlessly when cooled — a simple but crucial first step.

Step 2: Cream the Butter and Sugars

In a large mixing bowl, beat together the room-temperature butter with both the dark brown sugar and granulated sugar along with vanilla extract until smooth and creamy. This combination lays down the luscious base of your cookie dough, setting the stage for that chewy texture and balanced sweetness.

Step 3: Add the Eggs

Beat in the two large eggs and the additional egg yolk, one at a time, ensuring each is fully incorporated. These eggs provide the binding power that keeps the cookies perfectly soft and chewy without crumbling.

Step 4: Mix Dry Ingredients & Oats

Combine the all-purpose flour, baking soda, baking powder, and salt in one bowl, then gradually add this to your wet mixture. Beat until everything is well combined, then fold in the old fashioned oats for that classic hearty texture that makes these monster cookies truly special.

Step 5: Fold in the Goodies

Now comes the fun part—gently fold in 1 cup of holiday-red and green M&M’s, salted pretzel pieces, semi-sweet chocolate chunks, and white chocolate chips. Each adds a burst of flavor and texture, making these cookies a festive masterpiece.

Step 6: Shape Your Cookies

Use about 1/4 cup measuring scoop or your hands to roll dough balls and place them on the prepared baking sheets, leaving at least 3 inches of space between each to allow for spreading. This size gives you large, monster-worthy cookies full of fun and flavor.

Step 7: Bake with Care

Bake the cookies for 8 minutes, then rotate the pan to ensure even cooking and bake for an additional 2 minutes. This timing creates that perfect chewy-soft center while still having slightly crisp edges.

Step 8: Add More M&M’s & Finish Baking

After the initial bake, pull the cookies out and press the remaining 1/4 cup of M&M’s into the tops for an extra festive pop of color. Pop them back in the oven for another 2 to 3 minutes to let the candy settle beautifully on top.

Step 9: Cool & Enjoy

Remove from the oven and allow your cookies to cool right on the baking sheet. They continue to set as they cool, providing that perfect chewy consistency. Better yet, grab one while it’s still warm for a gooey taste experience you will love!

Garnishes

This recipe shines on its own, but if you want to dress it up for serving, try sprinkling a light dusting of powdered sugar or adding a drizzle of melted white or dark chocolate over the cooled cookies. These touches amplify their appeal and add a little extra holiday sparkle.

Side Dishes

Serve these joyful cookies alongside a cold glass of milk, a steaming cup of hot cocoa, or your favorite holiday coffee. These pairings highlight the sweetness and richness of the cookies and bring comforting warmth to your dessert moment.

Creative Ways to Present

For an eye-catching holiday display, arrange these monster cookies on a festive platter surrounded by pine sprigs, holly berries, or mini candy canes. Wrapping individual cookies in clear cellophane with a joyful ribbon makes charming gifts or party favors that everyone will adore.

Make Ahead and Storage

Storing Leftovers

Once fully cooled, store your Christmas Monster Cookies in an airtight container at room temperature. They stay fresh and chewy for up to a week, making them perfect for prepping ahead of holiday gatherings or keeping on hand for spontaneous cookie cravings.

Freezing

If you want to save some for later, freeze the cookie dough balls or baked cookies separately in airtight containers or freezer bags. Dough balls freeze great and can be baked directly from frozen with a slight increase in baking time. Baked cookies freeze well for up to 3 months and thaw quickly at room temperature.

Reheating

To bring back that fresh-baked warmth, gently microwave a cookie for about 10 to 15 seconds or warm them in a low oven for a few minutes. This revives that soft, chewy texture and melty chocolate goodness just like fresh from the oven.

FAQs

Can I use other types of chocolate instead of semi-sweet chunks?

Absolutely! Feel free to substitute with milk chocolate, dark chocolate, or even butterscotch chips to customize the flavor profile to your liking. Each variation brings a unique twist to the Christmas Monster Cookies Recipe.

Are these cookies gluten-free?

The original recipe calls for all-purpose flour, which contains gluten. However, you can try substituting with a gluten-free flour blend. Just be aware that texture may vary slightly, but the overall deliciousness will still shine through.

Can I make these cookies vegan?

To make a vegan version, swap the butter for a plant-based alternative, use flaxseed eggs or chia eggs instead of real eggs, and choose vegan chocolate chips. The cookie might turn out a bit different in texture but still super tasty and festive!

How do I keep the pretzels crunchy inside the cookies?

Break the pretzels into medium-sized pieces and fold them in gently at the end so they don’t get flattened or soggy. Baking at the right temperature for just the recommended time preserves their crunch in every bite.

Can I make these cookies smaller or larger?

Definitely! Rolling smaller dough balls will give you bite-sized cookies, perfect for parties, while larger ones make chunky, filling treats. Just adjust baking times accordingly—smaller cookies need less time, larger ones need a little more to bake through.
