1-Baking these Christmas Sugar Cookie Bars is straightforward and rewarding, turning your kitchen into a hub of holiday cheer. Start by preheating your oven to 350°F and lining a 9×9 inch baking pan with parchment paper for easy cleanup. This simple setup ensures your bars come out perfectly every time.

2-In a large bowl, beat together the softened butter and sugar until it’s light and fluffy, which usually takes about 2-3 minutes with an electric mixer. Add the egg and vanilla extract next, blending until smooth to create a solid base for your dough. Then, gradually mix in the flour and baking powder to form a thick dough, stirring in the sprinkles gently to keep their color bright.

3-Spread the dough evenly in the pan it might be thick, so use a spatula to press it down. Bake for 20 minutes or until the edges are golden brown, then let it cool completely before frosting. For the frosting, blend the powdered sugar, butter, cream cheese, vanilla, and milk until creamy, then spread it over the cooled bars and add extra sprinkles.
