I searched high and low for a substitute for the type sold at the grocery store and found this on the internet...hoping it will work well for a fruit pizza I am planning to make. (Note: prep time does not include at least 2 hours of chill time).
Combine flour, baking powder, and salt in a small bowl.
With a mixer on medium speed, beat sugar, butter, egg, and vanilla in a large bowl 2 minutes, until smooth and creamy. Using a wooden spoon, stir in flour mixture. Shape into a 15-inch-long log; wrap in plastic wrap and refrigerate at least 2 hours or up to 3 days.
When ready to bake, heat oven to 350 degrees.
Cut dough into 1/4-inch-thick slices. Place on ungreased baking sheets, reshaping into rounds if necessary.
Bake in heated 350 degree oven 10 to 12 minutes or until cookies are lightly golden around edges. Remove baking sheets to wire racks and cool 1 minute. Remove cookies to racks and let cool completely.
