Amazing Sugar Cookie Bars that are soft, fluffy and absolutely delicious! Half the work of traditional sugar cookies and taste just as good! Topped with a rich buttercream frosting to make the ultimate sweet treat!
Preheat oven to 350°F. Combine flour, salt and baking powder in a medium-sized bowl. Set aside.
With a mixer, combine butter, sugar and powdered sugar until fluffy (about 3 minutes). Pour in vanilla, eggs and sour cream and mix until combined. Then pour dry ingredients into this bowl and mix until combined.
Place mixture in a buttered 9×13 glass pan. Press down on dough with hands (or a piece of parchment paper) to smooth out the surface to avoid lumpiness.
Bake for 20 minutes or until lightly browned. Do not over cook.
For Buttercream Frosting:
Combine ingredients in a large bowl and beat with a mixer for 2 minutes, or until fluffy.
Once sugar cookie bars have cooled completely, pour frosting over top and spread evenly with a spatula.
Optional: Top with sprinkles for a decorative touch!
