Instructions: Preheat oven to 350 degrees. Line 2 large baking sheets with parchment paper.

Mix flour, baking powder and salt in medium bowl. Using electric mixer, beat butter, peanut butter and vanilla in large bowl until well blended. Beat in both sugars. Scrape down sides of bowl. Stir half of dry ingredients into mixture. Add eggs 1 at a time, stirring well after each addition. Mix in remaining dry ingredients.

For each cookie, roll 1 heaping tablespoonful of dough into 1 3/4-inch-diameter ball. Arrange dough balls 2 1/2 inches apart on prepared baking sheets. Using back of fork, flatten dough balls and form crosshatch design on tops.

Bake cookies until dry on top and golden brown on bottom, about 14 minutes. Cool cookies on baking sheets 5 minutes. Using metal spatula, transfer cookies to racks and cool completely. (Can be prepared up to 3 days ahead. Store in airtight container at room temperature.)

This recipe yields about 4 dozen.
