1 box chocolate cake mix (Betty Crocker Super Moist)
3 tablespoons vegetable oil
1 1/4 cups chocolate syrup
2 cups evaporated milk
3/4 cup chopped walnuts

Preheat oven to 350°F

Line a 9x13x2-inch brownie pan with foil or parchment paper and spray with non-stick spray.

Combine cake mix, oil, chocolate syrup and evaporated milk in mixing bowl.

Beat on medium-low speed for 1 minute. Scrape down sides and stir in nuts.

Spread batter evenly in pan. Bake in preheated oven for 18 to 22 minutes or until a wooden pick inserted in center comes out nearly clean (crumbs will adhere).
