Preheat oven to 400°F. Combine 1/4 cup powdered sugar, peanut butter and 1/4 cup maple syrup in small bowl until well blended; set aside.

Cut pastry dough into 3-inch-wide strips. Place rounded teaspoon peanut butter mixture about 1 inch from 1 end of each strip.

Starting at end of each strip with filling, fold corner of pastry dough over filling so it lines up with other side of strip, forming a triangle. Continue folding like a flag in triangular shape, using entire strip. Repeat process with remaining pastry dough and filling.

Place triangles about 2 inches apart on ungreased baking sheets, seam-side down; spray with cooking spray. Bake 6 to 8 minutes or until golden brown. Remove from baking sheets to wire rack to cool.

Combine remaining 1 cup powdered sugar, 3 tablespoons syrup and 1 tablespoon water in small bowl. Add additional water, if needed, for desired consistency. Glaze cookies just before serving.
