Chocolate-Cherry Bars

Preheat oven to 325 degrees F. Coat an 8-by-12-inch baking dish with nonstick cooking spray.

Beat together eggs, egg white, sugar, vanilla and salt in a large bowl with an electric mixer on high speed until the eggs are thick and pale, about 2 minutes. Gently fold in chocolate wafer crumbs and cherries with a rubber spatula just until combined.

Transfer the batter to the prepared baking dish; smooth the top. Sprinkle with walnuts. Bake until a knife inserted in the center comes out clean, 30 to 35 minutes.

Let cool in the baking dish on a rack. Cut into 15 bars. Store at room temperature in an airtight container.
