01 -
Set your oven to 350°F. Coat a 9x13-inch pan with grease.
02 -
Whisk cake mix, eggs, frosting, oil, and milk until there are no lumps. Blend in the pecans at the end.
03 -
Put the batter into the pan and bake for 35 to 40 minutes. Check with a toothpick—it should come out dry.
04 -
Right out of the oven, use the handle of a wooden spoon to create holes halfway through the cake.
05 -
Warm condensed milk and butter until it simmers gently. Turn off heat, then mix in vanilla and pecans.
06 -
Drizzle the warm sauce all over the cake, letting it seep into the holes. Sprinkle pecans on top afterward.
07 -
Pop the cake into the fridge and leave it for at least an hour. This will taste better once chilled.
