Shortbread Cookies - cooking recipe

Ingredients

2 cups flour
1 cup butter, softened
1/2 teaspoon baking powder
1/2 cup sugar
1 large egg
1 freshly grated lemon zest

Preparation

Sift flour and baking powder together in a small bowl.
Cream butter, add sugar slowly, mixing well.
Mix in egg and lemon zest.
Add flour/baking powder mixture, mix in well.
Shape into balls about the size of a golf ball, place on pan, flatten slightly with the bottom of a glass.
Bake at 300\u00b0 for 15-20 minutes, just until a bit golden on the edges.
These last well if kept in a tightly covered container, and actually taste even better after a day or two as the flavors develop.
