Ingredients:

  • 1 box (15.25 oz) chocolate cake mix
  • 3 large eggs
  • 1 cup water
  • 1/2 cup vegetable oil
  • 1 can (14 oz) sweetened condensed milk
  • 1/2 cup warm milk
  • 1 tsp vanilla extract
  • 8 oz semi-sweet chocolate chips
  • 1 cup heavy whipping cream
  • 1 tbsp unsalted butter

Instructions:

  1. Preheat oven to 350°F (175°C). Combine cake mix, eggs, water, and oil; beat until smooth and pour into a greased 9x13 inch baking pan.
  2. Bake for 30 minutes or until the edges slightly pull away from the pan and a toothpick inserted in the center comes out clean.
  3. While the cake is still warm, use a wooden skewer to poke holes across the surface, roughly 1 inch apart and 2/3 of the way deep.
  4. Whisk together the sweetened condensed milk, warm milk, and vanilla extract. Slowly pour the mixture over the cake, ensuring it fills the holes. Let cool to room temperature.
  5. Heat heavy whipping cream until it begins to simmer. Pour hot cream over chocolate chips and let sit for 5 minutes.
  6. Stir in room temperature butter and mix until the ganache is smooth. Spread evenly over the cooled cake.
  7. Chill the cake in the refrigerator for 4 hours to allow the ganache to set and the soak to fully absorb.
