How To Make Christmas Sugar Cookie Bars

Step 1. Use parchment paper to line a 9×13-inch baking dish and set it aside. Set the oven to 375 degrees. Add the butter and sugar into a large bowl and use an electric mixer to combine until light and fluffy. Put in the eggs and vanilla and combine again. Add the flour, baking soda, and salt into the mixture and combine until a dough forms. Put the dough into the prepared pan and spread it out to cover the bottom. Place into the oven for 12-15 minutes to bake until puffed and light brown. Let the bars cool thoroughly and prepare the frosting while the bars cool.

Step 2. Add the butter into a large bowl and beat to whip with an electric mixer. Put in the powdered sugar and beat again. Pour in the milk and vanilla and combine once again until light and fluffy. Put the frosting on top of the cooled bars and spread evenly with a spatula. Top with holiday sprinkles or chips and cut into bars. Serve and enjoy!
