What Kind of Frosting Should I Use?

A classic vanilla buttercream is the perfect topping for these cookie bars. It complements the soft sugar cookie base with its creamy texture and rich sweetness. You can also switch it up with a cream cheese frosting if you like a tangy twist or go for a simple powdered sugar glaze if you’re short on time.

How To Make the Festive Cookie Bars

Step 1: Prep Your Pan and Oven

Preheat your oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper or lightly grease it to prevent sticking.

Step 2: Cream the Butter and Sugar

In a large mixing bowl, beat the softened butter and granulated sugar until light and fluffy. This step is essential for creating that soft cookie texture.

Step 3: Add Eggs and Vanilla

Beat in the eggs one at a time, followed by the vanilla extract. Mix until fully combined.

Step 4: Combine Dry Ingredients

In a separate bowl, whisk together the flour and baking powder. Slowly add this dry mixture to the wet ingredients and mix until a soft dough forms.

Step 5: Bake the Cookie Base

Spread the dough evenly into your prepared pan. Bake for 20–25 minutes or until the edges are lightly golden and a toothpick comes out clean. Let the cookie base cool completely.

Step 6: Make the Frosting

In a clean bowl, whip together the butter, powdered sugar, vanilla extract, and milk until light and fluffy. Adjust the consistency by adding more milk if needed.

Step 7: Frost and Decorate

Spread the frosting evenly over the cooled cookie bars. Finish with a generous amount of red and green sprinkles.

Step 8: Slice and Serve

Cut into squares or rectangles, and serve! These bars are festive, easy to transport, and even easier to eat.
