Ingredients List

For these magnificent Christmas monster cookies, you’ll need:

  • 1 cup creamy peanut butter (use natural for a less sweet option)
  • 3/4 cup light brown sugar, packed
  • 1/2 cup granulated sugar
  • 2 large eggs, at room temperature
  • 1 tablespoon pure vanilla extract
  • 3 cups old-fashioned rolled oats
  • 1 cup all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt

  • Optional: 1/2 cup crushed peppermint candies for extra festive flavor

  • Cooking Time: 10-12 minutes per batch
  • Total Time: About 1 hour

These Christmas monster cookies take less time than traditional decorated holiday cookies, saving you roughly 45 minutes compared to cookies that require detailed icing work. The chilling time is perfect for preheating your oven and cleaning up your workspace!

Step-by-Step Instructions

Step 1: Prepare Your Wet Ingredients

In a large mixing bowl, cream together the softened butter and peanut butter until smooth and well combined, about 2 minutes. Add both sugars and beat until light and fluffy, approximately 3-4 minutes. This extended creaming creates air pockets that give your Christmas monster cookies their perfect chewy texture.

Step 2: Add Eggs and Vanilla

Add eggs one at a time, mixing well after each addition. Pour in the vanilla extract and mix until fully incorporated. The mixture should look glossy and smooth. Scrape down the sides of your bowl to ensure everything is evenly mixed.

Step 3: Combine Dry Ingredients

In a separate bowl, whisk together the oats, flour, baking soda, and salt. This pre-mixing ensures your leavening agent is evenly distributed throughout the dough, preventing any bitter spots in your Christmas monster cookies.

Step 4: Combine Wet and Dry Mixtures

Gradually add the dry ingredients to the wet mixture, mixing on low speed just until combined. Over-mixing can lead to tough cookies, so stop as soon as the flour disappears.

Step 5: Fold in the Mix-ins

Gently fold in the M&Ms, chocolate chips, white chocolate chips, and crushed peppermint (if using). Reserve a small handful of M&Ms to press on top of the cookies before baking for a more festive appearance.

Step 6: Chill the Dough

Cover the dough and refrigerate for at least 30 minutes. This crucial step prevents spreading and enhances the chewy texture of your Christmas monster cookies.

Step 7: Bake to Perfection

Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper. Scoop dough using a 2-tablespoon cookie scoop, placing cookies 2 inches apart. Press reserved M&Ms on top. Bake for 10-12 minutes until edges are set but centers still look slightly underdone.

Step 8: Cool Properly

Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack. This prevents your Christmas monster cookies from breaking apart while they’re still soft from the oven.

Common Mistakes to Avoid

  • Overbaking: Remove cookies when they still look slightly underdone in the center
  • Adding all mix-ins at once: Fold them in gradually to ensure even distribution throughout the dough

Storing Tips for the Recipe

  • Counter Storage: Keep in an airtight container for up to 5 days
  • Refrigerator: Store for up to 1 week in a sealed container
  • Freezer: Freeze baked cookies for up to 3 months, separated by parchment paper

FAQs

Can I make these cookies without peanut butter?
Yes! Substitute almond butter, cashew butter, or sunflower seed butter in equal amounts for a different flavor profile or allergen-friendly option.

Why did my cookies spread too much?
This typically happens if the dough wasn’t chilled long enough or if the butter was too warm. Make sure to chill the dough properly and start with room temperature (not melted) butter.

Can I use regular M&Ms instead of Christmas colors?
Absolutely! While red and green create that festive appeal, any color M&Ms will work deliciously in these Christmas monster cookies.

How do I know when the cookies are done baking?
The edges should be set and lightly golden, but the centers should still look slightly underdone. They’ll continue cooking from residual heat after you remove them from the oven.

Can I double this recipe for a large gathering?
Yes! This recipe doubles beautifully. Just be sure to use a large enough bowl for mixing and maintain the same chilling and baking times.
