2 1/2CUPS all-purpose flour
1/4CUP cornstarch
1TSP baking powder
pinch of salt
3/4CUP butter, softened or margarine
1CUP sugar
1TSP vanilla extract
2 eggs
Combine flour, cornstarch, baking powder, and salt. Set the bowl aside.
In another bowl, cream the butter with the sugar and vanilla. Add the eggs, one at a time, and continue beating until smooth. With a wooden spoon, combine with the dry ingredients that you have put aside.
Use your hands, shape the dough into two discs. Cover them with plastic wrap and refrigerator for an 1 hour.
On a floured work surface, roll out the dough to about 3 to 5-mm (1/8 to 1/4-inch) thick. Cut out cookies, using a cookie cutter. Spread the cookies of the same size on the same sheet, because the cooking time may vary.
Bake, one sheet at a time, 8 to 10 minutes take out before edges get browned. Let them cool.
