Method
- Preheat your oven to 350 degrees F. Prepare the cake mix following the package directions, adding 1 teaspoon of vanilla and the salt before mixing the batter.
- Transfer the batter to a greased 13x9-inch baking pan. Bake and cool the cake completely as the package directs.
- Whisk the peanut butter and the sweetened condensed milk together until they blend. Use the end of a wooden spoon handle to poke holes in the cake about 2 inches apart.
- Slowly pour 2 cups of the peanut butter mixture over the cake, making sure to fill each hole. Cover the cake and the remaining peanut butter mixture, then refrigerate for 2 to 3 hours until the cake is cold.
- Combine the remaining vanilla extract with the rest of the peanut butter mixture. Gradually beat in enough confectioners' sugar until you reach a spreading consistency.
- Spread the frosting over the cold cake. Add your desired toppings. Refrigerate any leftovers.

Notes
This recipe is designed for speed using a mix, but you can substitute your favorite homemade chocolate cake recipe if you prefer. The chilling time is necessary for the filling to set properly, so plan ahead for that step.
