Trust me, these cookies are not just treats; they’re a delicious way to create cherished holiday traditions that you’ll look forward to every year!

Ingredients List

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1 cup butter, softened
1 cup packed brown sugar
1 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
3 cups quick oats
2 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt
1 cup chocolate chips
1 cup M&Ms

How to Prepare Christmas Monster Cookies

Making these *Christmas monster cookies* is a fun and straightforward process that will fill your kitchen with festive cheer! Let’s get started!

Step-by-Step Instructions

First things first, preheat your oven to 350°F (175°C). This is super important so your cookies bake evenly and come out just right!
In a large mixing bowl, cream together 1 cup of softened butter, 1 cup packed brown sugar, and 1 cup granulated sugar. Use an electric mixer on medium speed until the mixture is light and fluffy—this usually takes about 2 minutes. Don’t rush this step; it’s key for that delicious texture!
Next, add in 2 large eggs and 1 teaspoon of vanilla extract. Mix again until everything is beautifully combined.
In a separate bowl, whisk together 3 cups of quick oats, 2 cups of all-purpose flour, 1 teaspoon of baking soda, and 1/2 teaspoon of salt. This will help your dry ingredients mix more evenly into the wet ones.
Now, gradually add the dry mixture to your wet ingredients. Stir until just combined—be careful not to overmix! The dough should be thick and slightly sticky, but still manageable.
Finally, fold in 1 cup of chocolate chips and 1 cup of M&Ms. This is where the fun starts! Use a spatula to gently mix them in; you want to see those colorful candies and chocolate bits peeking out.
Drop spoonfuls of dough onto a baking sheet lined with parchment paper, leaving enough space between each scoop for the cookies to spread.
Bake in your preheated oven for about 10-12 minutes, or until they’re lightly golden around the edges. They’ll look a bit soft in the center, but don’t worry, they’ll firm up as they cool.
Once done, allow them to cool on a wire rack before serving. Trust me, the wait will be worth it!

Tips for Success

To make sure your *Christmas monster cookies* turn out perfectly every time, I’ve got some handy tips to share!

Ingredient Substitutions: If you’re out of butter, you can use margarine or even coconut oil for a delightful twist. For a healthier option, try substituting half of the all-purpose flour with whole wheat flour. Just keep in mind the texture might be a tad different!
Cookie Dough Consistency: Don’t worry if your dough feels a bit stickier than you expected. That’s a good sign! It means you’ve got a nice, gooey mixture that’ll bake up chewy and delicious.
Baking Times: Every oven is a little different, so keep an eye on your cookies as they bake. If they look a bit too soft at the end of the suggested baking time, give them an extra minute or two. Just be careful not to overbake them; we want that soft, chewy center!
Storing for Freshness: Once your cookies are completely cool, store them in an airtight container at room temperature. They’ll stay fresh for up to a week. If you want to keep them longer, you can freeze them! Just layer them between parchment paper in a freezer-safe bag, and they’ll be ready to enjoy whenever you need a sweet fix.
Mixing in Extras: Feel free to get creative with extra mix-ins! Chopped nuts, dried cranberries, or even a sprinkle of cinnamon can elevate these cookies to new heights. Have fun experimenting!

Variations of Christmas Monster Cookies

If you’re anything like me, you love to mix things up in the kitchen! These *Christmas monster cookies* are super versatile, and you can easily customize them to suit your taste or to use what you have on hand. Here are some fun variations to try:

Nuts: Add a cup of chopped walnuts or pecans for a delightful crunch. They add a wonderful texture and pair beautifully with the chocolate and oats.
Dried Fruit: Toss in some dried cranberries or raisins for a touch of sweetness and chewiness. They’ll give your cookies a lovely burst of flavor!
Seasonal Spices: Want to amp up the holiday spirit? Mix in a teaspoon of cinnamon or nutmeg for a warm, cozy flavor that screams festive cheer.
Peanut Butter Swirl: For a nutty twist, you can swirl in some creamy peanut butter into the dough. It adds a rich flavor that complements the chocolate perfectly.
White Chocolate and Macadamia: Switch out the regular chocolate chips for white chocolate chips and add macadamia nuts for a decadent tropical vibe.
Fun Sprinkles: If you’re feeling extra festive, sprinkle some holiday-themed sprinkles on top of the dough before baking. They’ll add a pop of color and fun!

Feel free to mix and match these ideas based on your cravings or what you have in your pantry. The possibilities are endless, and that’s what makes baking so exciting! Happy experimenting!

Storage & Reheating Instructions

Once your delicious *Christmas monster cookies* are baked and cooled, it’s important to store them properly to keep them fresh and tasty! Here’s how I do it:

Airtight Container: Store your cookies in an airtight container at room temperature. This helps to maintain their softness and keeps them from drying out. I usually layer them with parchment paper to prevent them from sticking together.
Room Temperature: If stored correctly, these cookies will stay fresh for about a week. They’re so good that they usually don’t last that long in my house!
Freezing for Later: If you want to save some for a later date (or hide them from yourself!), you can freeze them! Just place the cookies in a freezer-safe bag or container, layering them with parchment paper. They can last up to 3 months in the freezer. When you’re ready to enjoy them, just let them thaw at room temperature.

If you prefer your cookies warm and gooey, here’s a quick way to reheat them:

Microwave: Pop a cookie in the microwave for about 10-15 seconds. This will warm it up nicely and make it soft again.
Oven: Preheat your oven to 350°F (175°C), place the cookies on a baking sheet, and heat for about 5 minutes. This method brings back that fresh-out-of-the-oven magic!

Trust me, there’s nothing quite like enjoying a warm cookie with a glass of milk, especially during the festive season!

FAQ Section

Can I store my Christmas monster cookies in the freezer?
Absolutely! You can freeze these cookies for up to 3 months. Just make sure to layer them with parchment paper in a freezer-safe container or bag to prevent sticking. When you’re ready to enjoy them, let them thaw at room temperature.

What can I use instead of eggs for a vegan version?
If you’re looking to make these cookies vegan, you can substitute each egg with 1/4 cup of unsweetened applesauce or 1/4 cup of mashed bananas. They work wonderfully to bind the ingredients together!

How do I know when my cookies are done baking?
You’ll want to keep an eye on them! The cookies are done when they’re lightly golden around the edges but still look a bit soft in the center. They’ll firm up as they cool on the wire rack, so don’t worry if they seem a little underbaked.

Yes, you can! Quick oats work perfectly in this recipe. They’ll give your cookies that chewy texture we all love. Just avoid using steel-cut oats, as they won’t soften properly during baking.

What’s the best way to store leftover cookies?
To keep your cookies fresh, store them in an airtight container at room temperature. Just make sure they’re completely cooled before you seal them up! They should stay soft and delicious for about a week.
