Preheat the oven to 350 degrees. Grease an 8x8 baking pan and set aside OR use a parchment sling.

In a bowl or mixer beat butter and sugar until light and fluffy - about 1 minute. Add the egg and vanilla extract and beat until fully incorporated.
Add the flour and baking powder and continue mixing until incorporated.
Add the batter to the greased baking dish. Press down to flatten. Bake for 20 to 22 minutes or until golden brown on the edges.
Remove the cookie bars the oven and let them cool completely before frosting. (At least 25 minutes)
Once the cookies are cooled, spread the frosting on top. Decorate with the sprinkles. Slice the bars & enjoy!
