Preheat oven to 350 degrees – yields 2-3 dozen cookies
In a large bowl cream together butter and sugar.
Add in egg and mix until incorporated.
Stir in baking powder, salt, vanilla and 2 cups of flour. The mixture will seem to be very dry at first – you may need to use your hand to really mix it in and if it is too sticky add another 1/4 cup of flour.
Roll dough into one inch circles, roll into sugar and place on parchment paper lined cookie sheet.
If you would like to add sprinkles to your cookies press them down into a cup of sprinkles so just the tops will have them.
Gently push and bake for 9 minutes.
Remove from the oven and let them set on the cookie sheet for one minute before placing them on a wire rack to cool completely.
