Set your oven to 350°F and let it get warm. Use aluminum foil to line a 9×13-inch pan, then spray it lightly with cooking oil so nothing sticks.

Mix up the Devil's Food cake following the box's instructions—usually you're adding eggs, water, and oil. Keep stirring till it's smooth, then pour into your prepared pan.
03 -
Slide the cake into the oven and bake it like the box says. A tip? Check it about 3 minutes early, as it might cook quicker than expected!

While your cake bakes, combine the caramel sundae sauce with the sweetened condensed milk in a bowl. Stir it together till smooth.
05 -
After baking, pull out your cake and while it's still warm, use the handle end of a wooden spoon to make about 60 evenly spaced holes across the surface.
06 -
Carefully pour the caramel-and-milk mixture over the cake, letting it sink into all the holes you poked. Go slow and be thorough so everything gets absorbed.
07 -
Let your cake hang out in the fridge for roughly 10 minutes to cool before moving to the next step.
08 -
Spread the whipped topping evenly over your cake. Sprinkle on the mini chocolate chips and the chopped pecans to cover the top completely.
09 -
Pop the cake back in the fridge and leave it covered for at least 2 hours, or better yet, let it chill overnight so the flavors can fully combine.

Right before serving, drizzle salted caramel sauce evenly across the top. Cut it into squares and enjoy the reactions when people take a bite!
