Christmas Monster Cookies

Sharing is caring!

Monster cookies are such a fun classic to make, so I decided to make Christmas Monster Cookies for the holiday season! These are soft, chewy, and super special with festive red and green M&Ms!

What Are Monster Cookies?

Monster Cookies are a playful and versatile cookie variety known for their vibrant appearance and mix of diverse add-ins. These cookies often feature a base of oats and peanut butter, and the “monster” element comes from the variety of mix-ins like M&M’s, chocolate chips, and nuts. Each bite is an adventure, combining chewiness, crunch, and a burst of flavors.

Christmas Monster Cookies Ingredients:

• Unsalted Butter, Softened: Adds richness and moisture to the cookies.
• Granulated Sugar: Sweetens the cookies and contributes to their texture.
• Light Brown Sugar, Packed: Provides a deeper sweetness and adds moisture, contributing to a chewy texture. You can also use dark if you want
• Eggs: Act as a binding agent and contribute to the structure of the cookies.
• Vanilla Extract: Enhances the overall flavor profile of the cookies.
• Old-Fashioned Oats: Add texture and a hearty, chewy element to the cookies.
• All-Purpose Flour: The primary structure-building ingredient in the cookies.
• Baking Powder: Contributes to the cookies’ rise and tenderness.
• Baking Soda: Helps with the cookies’ leavening and browning.
• Salt: Enhances the overall flavor, balancing the sweetness.
• Creamy Peanut Butter: Adds a rich, nutty flavor and contributes to the cookies’ chewiness.
• M&M’s: Introduce bursts of color and chocolatey goodness. Also adds a nice crunch !
• Chocolate Chips: Provide additional chocolate flavor and texture.

Instructions:

1. Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.
2. In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
3. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
4. In a separate bowl, whisk together the old-fashioned oats, all-purpose flour, whole wheat flour, baking powder, baking soda, and salt.
5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
6. Fold in the creamy peanut butter until evenly distributed throughout the cookie dough.
7. Gently fold in the M&M’s or Smarties, chocolate chips, and chopped nuts if using.
8. Drop rounded tablespoons of dough onto the prepared baking sheets, leaving enough space between each for spreading.
9. Bake in the preheated oven for 10-12 minutes or until the edges are lightly golden but the centers are still soft.
10. Allow the cookies to cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
11. Repeat with the remaining cookie dough.
12. Once cooled, store these soft and chewy Christmas Monster Cookies in an airtight container.

Unwrapping the Joy:

• Festive Fusion: The mix of M&M’s or Smarties, chocolate chips, and optional nuts creates a festive medley of textures and flavors.
• Versatile Treat: Perfect for holiday parties, cookie exchanges, or simply enjoying by the fireplace with a cup of cocoa.
• Kid-Friendly Fun: Get the little ones involved in the kitchen for a merry baking experience.
