Set oven to 350°F. Grease up a 9x13 pan to get it ready.
02 -
Stir together the cake mix, frosting, eggs, oil, and milk until there are no lumps. Gently fold in pecan pieces.
03 -
Spread batter in the pan and bake for 35-40 minutes. Insert a toothpick to check; it should come out dry.

Using a wooden spoon handle, make holes halfway deep in the hot cake.
05 -
Warm up the butter and condensed milk until it simmers. Take it off heat, then mix in vanilla and pecans.
06 -
Drizzle the warm sauce over the cake. Give the pan a gentle shake to help it seep into the holes, then add some pecans on top.

Pop the cake into the fridge for at least an hour. That’ll let the flavors come together nicely.
