Christmas cookie bars are the best way to celebrate the holidays! Warm, gooey, and delicious, they feature a soft, brownie-like texture and are bursting with chocolate chips, bright and festive holiday sprinkles, and chocolatey candy.

Christmas Cookie Bars raw ingredients that are labeled

You’ll need:

  • ½ cup unsalted butter, melted
  • ½ cup packed light brown sugar
  • ⅓ cup granulated sugar
  • 1 large egg, room temperature
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • ¼ teaspoon salt
  • ½ cup semi-sweet chocolate chips
  • ½ cup red and green M&M’s candy
  • ¼ cup Christmas jimmies
  • additional Christmas sprinkles for sprinkling over the baked cookie bars, if desired

SUBSTITUTIONS AND ADDITIONS

SPRINKLES: Jimmies are the best choice for adding to the batter as the dye will not bleed. Other sprinkles should only be added to the top of the cookies; if stirred in, they will turn the batter a greenish-brown color.

CHOCOLATE CHIPS: Swap the chocolate chips for butterscotch chips, peanut butter chips, milk chocolate chips, or white chocolate chips in this great recipe.

NUTS: Add chopped walnuts or other chopped nuts to these sweet treats for a bit of extra crunch.

TOPPING: Add a drizzle of caramel sauce to make these classic cookie bars extra sweet.

OUR RECIPE DEVELOPER SAYS

These cookie bars freeze well. Make a double batch and keep them in the freezer for a homemade holiday gift during the festive season.

STEP ONE: Preheat the oven to 350°F. Brush an 8×8-inch square baking pan with a bit of the melted butter and line the pan with parchment paper, leaving a 2-inch overhang on two sides.

PRO TIP:

Adding the overhanging parchment paper will allow you to lift the bars out of the pan for easy transfer to a cutting board so you can slice the bars.

STEP TWO: In a large bowl, whisk the remaining butter and sugars until smooth. Whisk in the egg and vanilla until fully incorporated.

STEP THREE: Add the flour and salt to the wet ingredients and mix just until moistened. Do not over-mix. 

PRO TIP:

Stir the batter together gently to keep the cookies soft and chewy; overmixing can cause the bars to be crumbly and tough.

STEP FOUR: Fold in ½ cup chocolate chips, ⅓ cup of the M&M’s, and jimmies.

PRO TIP:

You can adjust the chocolate chips, M&M’s, and sprinkles amounts however you’d like. The quantities given here produce a chewy bar with lots of chocolate and sprinkle flavor.

STEP FIVE: Transfer the batter to the prepared pan and smooth the top with a rubber spatula. Sprinkle the top with the remaining M&M’s.

STEP SIX: Bake for 20 minutes or until the top is a golden brown color and a toothpick inserted into the center comes out clean.

PRO TIP:

Oven temperatures vary and may need to be recalibrated periodically to ensure they are accurate. Make sure to keep a close eye on your cookie bars as the suggested baking time approaches.

STEP SEVEN: Set the pan on a wire rack and sprinkle the top of the bars with additional sprinkles, as desired. Cool completely. Using the parchment overhang, lift the bars from the pan and transfer them to a cutting board. Cut into squares.

How To Serve

Serve these delicious treats fresh and warm from the oven with a scoop of vanilla ice cream and a dollop of whipped cream for an extra decadent dessert. They will also be a big hit at a cookie exchange or on a cookie plate at your Christmas celebrations.

IN THE FRIDGE: If you want to keep them for longer, this easy cookie bars recipe can be stored in the fridge for a week. Wrap the bars tightly with plastic wrap to keep the air from getting in and drying them out.

IN THE FREEZER: Store these chewy bars in the freezer for up to 3 months. Thaw on the counter when you are ready to serve them. You can eat them cold; however, pop them in the microwave in 15-second increments to make them soft and delicious once again.

    These bars are fantastic! I made a batch to see if they should go in my Christmas cookie gifts and Yes! They should! Next time I might leave out the chocolate chips and double up on M&Ms.
