Caramel Crumble Bars

1 box (15.25 ounces) yellow cake mix, dry
1/2 cup butter, softened, plus 4 tablespoons, divided
3/4 cup apple butter, plus 3 tablespoons
1 egg
1 package (11 ounces) caramels, unwrapped
2/3 cup walnuts, chopped
2/3 cup flaked coconut, sweetened

Heat oven to 350 degrees. Grease 13-by-9-inch baking pan. With electric mixer on low speed, beat dry cake mix and 1/2 cup softened butter until mixture is crumbly. Spoon 1 cup cake mix mixture into medium bowl; set aside. Add 3/4 cup apple butter and egg to remaining mixture. Beat on medium speed until smooth and creamy. Spread evenly into pan. Bake 20 minutes, or until starting to brown and top is set.

Place caramels, 2 tablespoons butter and remaining apple butter in microwavable bowl. Microwave on high 3 to 4 minutes, stirring every 30 seconds until smooth and melted. Pour caramel mixture evenly over partially baked crust. If caramel cools and sets, microwave 1 minute until soft and pourable.

Combine walnuts, coconut and 2 tablespoons melted butter with reserved cake mix mixture. Mix until crumbly. Break up topping and sprinkle evenly over caramel. Bake 16-18 minutes or until topping is starting to brown. Cool completely before cutting into bars.
