These Sugar Cookie Bars are so yummy and much easier to make than traditional sugar cookies! The dough is baked in one pan, then topped with a homemade vanilla frosting. Just slice and enjoy!
Preheat oven to 350 degrees. Line a 9 x 13 inch baking dish with parchment paper.
In a large bowl, beat together 1 stick of softened butter, brown sugar, and white granulated sugar with an electric mixer until light and fluffy.
In a small bowl, sift together the flour, baking soda, baking powder, and salt.
