Set oven to 350°F and butter up a 9x13-inch pan.

Blend together cake mix, pecan frosting, eggs, oil, and milk till creamy. Stir in the pecans gently.

Poke holes through the top of the cake while it's still warm, about halfway deep, using the handle of a wooden spoon.
05 -
Simmer butter and condensed milk together. Take it off the heat, stir in chopped pecans and vanilla.

Drizzle the warm sauce on the hot cake. Lightly tap the pan to let it soak in. Sprinkle pecans over the top.

Pop it in the fridge for at least an hour before digging in—it tastes better cold.
