The Ultimate Holiday Sugar Cookie Bars

Preheat oven to 350°F and line an 8x8” baking pan with parchment paper. In a large bowl, whisk together melted coconut oil, sugar, egg yolk, and vanilla until smooth. Add in flour, baking soda, baking powder, and salt — mix until a soft dough forms. Press evenly into the pan and bake for 21–23 minutes, until the edges are lightly golden. Let cool completely before spreading on vanilla frosting. Top with Christmas sprinkles + slice into squares!
