Preheat your oven: Start by preheating your oven to the temperature specified on the cake mix package (usually around 350°F or 175°C). Grease and flour a 9x13 inch baking pan.
Prepare the cake batter: In a large mixing bowl, combine the yellow cake mix, water, vegetable oil, and eggs. Beat the mixture with an electric mixer for about 2 minutes, or until everything is well combined and smooth.
Bake the cake: Pour the batter into your prepared baking pan. Bake according to package instructions, typically for about 30-35 minutes, or until a toothpick inserted into the center comes out clean.
Poke the cake: Once the cake is done baking, let it cool in the pan for about 10 minutes. Next, use the handle of a wooden spoon to poke holes all over the cake, about an inch apart.
Prepare the pudding: In a separate bowl, whisk together the vanilla pudding mix and milk until it thickens. Pour this delicious mixture over the poke holes in the cake, ensuring that it seeps into all the holes.
Chill the cake: Refrigerate the cake for at least 2 hours, allowing the pudding to set and enhance the flavors.
Frost the cake: Before serving, spread the chocolate frosting evenly over the top of the cake. For added flair, you can also top it with whipped cream if desired.
Slice and serve: Cut into squares and serve this delightful treat to your family and friends—they’ll be swooning with every bite!
