Chocolate Crumble Bars

Crust & Crumble

• 1 box chocolate cake mix — 15.25 oz
• ⅓ cup vegetable oil
• 1 large egg
• 1 cup walnuts or pecans — chopped

Chocolate Filling

• 1 can sweetened condensed milk — 14 oz
• 1 cup semi-sweet chocolate chips — 6 oz
• 1 teaspoon vanilla extract
• 1 pinch salt

1. Prepare the Pan: Preheat oven to 350°F and grease a 9x13-inch baking pan.
2. Make Crumble Mixture: In a large bowl, combine chocolate cake mix, oil, and egg until evenly moistened coarse crumbs form and no pockets of dry cake mix remain. Stir in chopped nuts.1 box chocolate cake mix, 1/3 cup oil, 1 large egg, 1 cup nuts
3. Form the Crust: Reserve 1½ cups of the crumb mixture for topping. Press the remaining mixture firmly and evenly into the bottom of the baking pan.
4. Make Chocolate Filling: In a medium saucepan over low heat, combine sweetened condensed milk, chocolate chips, and salt. Stir constantly for 3 to 5 minutes until the chocolate is completely melted and the filling is smooth. Remove from heat and stir in vanilla.14 oz sweetened condensed milk, 6 oz chocolate chips, 1 tsp vanilla, salt
5. Assemble Bars: Spread chocolate filling evenly over the crust and sprinkle reserved crumb mixture across the top without pressing it into the filling.
6. Bake: Bake 25 to 30 minutes until the edges are firm and the crumb topping looks dry and set. Chocolate visible between the crumbs may still look moist, but it should no longer ripple like liquid when the pan is gently moved.
7. Cool Completely: Set the pan on a cooling rack and let the bars cool completely, about 2 hours, before slicing into squares.
