Method
- Preheat your oven to 350°F (175°C). Prepare the cake mix according to the package directions. Add 1 teaspoon of vanilla extract and the salt to the batter before mixing. Pour the batter into a greased 13x9-inch baking pan. Bake and cool the cake completely as directed on the package.
- In a mixing bowl, whisk together the creamy peanut butter and the sweetened condensed milk until well blended. Using the blunt end of a wooden spoon handle, poke holes in the cooled cake about 2 inches apart. Slowly pour 2 cups of the peanut butter mixture over the cake, ensuring it fills each hole.
- Cover the cake and the remaining peanut butter mixture. Refrigerate both for 2 to 3 hours, until the cake is cold.
- In a separate bowl, combine the remaining 1 teaspoon of vanilla extract with the reserved peanut butter mixture. Gradually beat in enough confectioners' sugar to achieve a spreadable consistency. Spread this frosting evenly over the chilled cake.
- Decorate the top of the cake with your chosen toppings, such as chopped peanut butter-filled sandwich cookies or peanut butter cups. Refrigerate any leftovers.

Notes
This recipe is a fantastic way to elevate a standard box cake mix. The peanut butter soak adds moisture and a rich flavor, while the frosting and toppings provide a gourmet finish. Feel free to experiment with different cookie or candy toppings to personalize your cake.
