How to Make Christmas Cookie Bars
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease or line your 9×13-inch baking pan with parchment paper to prevent sticking.
Step 2: Mix Wet Ingredients
In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth. Add in the eggs and vanilla extract; mix until fully combined.
Step 3: Combine Dry Ingredients
In another bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add this dry mixture into the wet ingredients, stirring until just combined.
Step 4: Add M&Ms and Chocolate Chips
Fold in ¾ cup of the red and green M&Ms along with the white chocolate chips. Reserve some M&Ms for topping later.
Step 5: Prepare for Baking
Spread the dough evenly into your prepared pan. Top with the remaining M&Ms, pressing them lightly into the dough.
Step 6: Bake Them Up
Bake in your preheated oven for 25-30 minutes or until you see golden edges. Check doneness by inserting a toothpick in the center; it should come out clean.
Step 7: Cool Before Serving
Allow the cookie bars to cool completely in the pan before slicing them into squares. Enjoy your festive treats!
