Are you craving a treat that's both easy to make and irresistibly tasty? Look no further than Sugar cookie bars! These delightful treats are a fun twist on the classic sugar cookie, and they're perfect for any occasion.
Preheat the oven to 350 degrees and butter the bottom and sides of a jelly roll pan (half sheet pan) which is 11x15 inches.
In the bowl of your stand mixer (paddle attachment on) whip the butter and sugar until light and fluffy, about 2 minutes. Add the eggs and beat to combine, around 30 seconds. Add the sour cream and vanilla and combine. Sprinkle the flour, baking powder, and salt over the top of the ingredient in the bowl and then mix on low until completely combined.
Spread the dough evenly in the buttered pan and then bake for 16-20 minutes until the dough is set but still light in color.
Allow the dough to cool completely before topping with frosting and sprinkles. Cut into bars and serve.
Notes
I love a traditional vanilla buttercream for this recipe but they are great with chocolate frosting on them too!
Sometimes I'll stir in 1/2 cup sprinkles to the batter before baking for that funfetti look; it's very cute.
You can use any kind of sprinkles or decorating ideas that you like or have on hand. The sprinkles are an easy way to make this dessert festive and fit the holiday or theme.
