Adding a swirl of pumpkin throughout this brownie batter is the perfect way to take your regular brownies into fall. You can add HERSHEY'S Chocolate Chips for an extra rich brownie, or HERSHEY'S Cinnamon Chips for an additional fall spice.
Heat oven to 325° F. Line 9x5-inch loaf pan with parchment paper, extending paper beyond pan edges.

Stir in egg, vanilla and salt. Add flour; stir vigorously until blended (about 50 strokes). Spread batter in prepared pan; set aside.
Combine pumpkin, remaining 1 tablespoon sugar, egg yolk and pumpkin pie spice in small bowl. Drop by teaspoons onto brownie batter; swirl with metal spatula or knife for marbled effect.
Bake 40 minutes or until wooden pick inserted into center comes out with moist crumbs. Cool completely in pan on wire rack. Use parchment paper to lift brownie out of pan. Cut into slices. Cover; refrigerate leftover brownies.
