Preheat your oven to 350°F (175°C). Prepare a 9x13 inch baking dish by greasing and lightly flouring it to prevent sticking.
In a large mixing bowl, combine the vanilla cake mix, eggs, and water. Using an electric mixer, beat the mixture on medium speed for 2 minutes until it is smooth and well combined.
Carefully pour the batter into the prepared baking dish. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center of the cake comes out clean. Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
Once the cake is completely cooled, use the handle of a wooden spoon or a long skewer to poke holes all over the surface of the cake, spacing them about 1 inch apart to ensure even soaking.
In a separate mixing bowl, whisk together the heavy cream, sweetened condensed milk, and vanilla extract until the mixture is well blended and creamy.
Gently pour the cream mixture over the entire surface of the poked cake, ensuring that the holes fill with the cream. Allow the cake to soak for at least 30 minutes in the refrigerator, although overnight soaking will yield even better results.
After the cake has absorbed the cream mixture, spread a generous layer of whipped cream evenly across the top of the cake.
Decoratively arrange the sliced strawberries over the whipped cream, using as many strawberries as desired for a colorful and appetizing appearance.
For an optional finishing touch, scatter fresh mint leaves on top of the strawberries to add a pop of color and a hint of refreshing flavor.
Notes
Serve chilled in square slices, drizzled with strawberry syrup for an enchanting presentation.
