Ingredients
- 1 cup unsalted butter, softened
- ½ cup brown sugar
- ½ cup granulated sugar
- 2 large eggs

- 2 cups all-purpose flour
- ¼ tsp salt
- ¾ cup mini chocolate chips
- 1 cup crushed Christmas Oreos
- 9 whole Christmas Oreos for layering
- ¼ cup Christmas M&M’s
How to Make Santa’s Cookie Bars

Preheat and Prepare the Pan
Start by preheating your oven to 350°F. Line an 8×8-inch baking pan with parchment paper, allowing a little overhang on the sides. This will help you lift the bars out later.
Cream the Butters and Sugars
In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until the mixture is light and fluffy—this should take about 2-3 minutes.
Add Eggs and Flavorings
Beat in the eggs, vanilla extract, and salt until the mixture is smooth and well combined, ensuring all ingredients are fully incorporated.
Combine Dry Ingredients
Mix in the all-purpose flour until just combined. Be careful not to overmix, as this can make the bars dense.
Fold in Festive Mix-Ins
Gently fold in the mini chocolate chips, M&M’s, and crushed Oreos, reserving a handful of each for the top decoration.
Layer the Dough and Cookies
Press about ⅓ of the cookie dough evenly into the bottom of the prepared baking pan. Arrange the nine whole Oreos in a single layer across the dough.
Top with Remaining Dough
Spread the remaining cookie dough gently on top, pressing it out evenly to cover the Oreos completely.
Add Finishing Touches
Sprinkle the reserved crushed Oreos and M&M’s over the top for a festive and colorful finish.
Bake to Perfection
Bake in the preheated oven for 22-25 minutes, or until the top is golden brown and a toothpick inserted in the center comes out mostly clean (a few crumbs are ideal).
Cool and Serve
Allow the bars to cool in the pan for about 10-15 minutes before lifting them out using the parchment overhang. Once cooled, slice into squares and enjoy!
Serving Suggestions
Pair these Santa’s Cookie Bars with a warm mug of hot cocoa or a glass of cold milk to enhance the holiday spirit. You can also serve them alongside vanilla ice cream for an indulgent treat.
Tips for Success
- Ensure your butter is softened at room temperature for easier creaming.
- Don’t overbake to maintain the chewy texture.
- Allow the bars to cool completely before slicing for cleaner cuts.
Variations
- Substitute the Christmas M&M’s with peanut butter M&M’s for a different flavor profile.
- Add chopped nuts such as pecans or walnuts for added crunch.
- Experiment with different types of Oreos based on your preference.

FAQs

4. Can I use margarine instead of butter?
While margarine can be used, butter provides a richer flavor that enhances the cookie bars.

Substitute all-purpose flour with a 1:1 gluten-free flour blend to make these cookie bars gluten-free without compromising texture.
