Soften butter with sugar, baking powder, vanilla and salt. Blend in egg and flour.

Grease or butter 2 cookie sheets well. Spread half of the dough out on each cookie sheet to make a 10x8 inch rectangle (one for each sheet).

Mix together ingredients for topping and sprinkle evenly over the dough.

Bake at 350°F for 12 to 15 minutes, or until golden brown along the edges. Allow to cool 2 minutes, then cut into 2 inch squares. Cool on wire racks.

Makes about 40.
