Ingredients
Cookie Dough
- 1 cup unsalted butter (softened)
- ½ cup brown sugar
- ½ cup granulated sugar
- 2 large eggs
- 1 tsp vanilla extract
- 2 cups all-purpose flour
- ¼ tsp salt
Mix-ins & Toppings
- ¾ cup mini chocolate chips
- 1 cup crushed Christmas Oreos (plus 9 whole Oreos for layering)
- ¼ cup Christmas M&M’s
Instructions
- Preheat the Oven: Set your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper to ensure the bars can be easily removed after baking.
- Cream the Butter and Sugars: In a large bowl, use a mixer to blend the softened unsalted butter with the brown sugar and granulated sugar until the mixture becomes light, fluffy, and well combined.
- Add Wet Ingredients: Mix in the eggs, vanilla extract, and salt, stirring until the batter is smooth and fully incorporated, ensuring even flavor throughout the dough.
- Combine Dry Ingredients: Gradually add the all-purpose flour to the wet ingredients, stirring just until the dough begins to come together to avoid overmixing which can toughen the bars.
- Fold in Mix-ins: Gently fold in the mini chocolate chips, Christmas M&M’s, and most of the crushed Christmas Oreos, reserving some for topping to create texture and festive color.
- Press Base Layer: Press about one-third of the cookie dough evenly into the bottom of the prepared baking pan, forming a firm base layer for the bars.
- Layer Whole Oreos: Arrange 9 whole Christmas Oreos in a single, uniform layer over the pressed dough, adding a fun and crunchy surprise inside the bars.
- Add Remaining Dough: Spread the remaining cookie dough gently over the Oreo layer, pressing carefully to cover them completely without disturbing the cookie arrangement underneath.
- Add Decorative Toppings: Sprinkle the remaining crushed Oreos and Christmas M&M’s over the top of the dough for an attractive, festive finish that adds additional crunch and color.
- Bake the Bars: Place the pan in the preheated oven and bake for 22 to 25 minutes, or until the top turns golden brown and a toothpick inserted near the center comes out mostly clean, indicating doneness.
- Cool and Slice: Remove the pan from the oven and allow the bars to cool for 10 to 15 minutes in the pan to set before slicing them into squares for serving.
Notes
- Make sure not to overmix the dough when adding flour to keep the bars soft and tender.
- Using parchment paper makes it easier to lift the bars from the pan without breaking.
- Allowing the bars to cool before slicing helps them hold their shape better.
- For added flavor, use Christmas Oreos specifically for a festive holiday touch.
- Store bars in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
