Preheat your oven to 350°F (175°C). Grease and flour a 9x13 inch baking dish.
In a large mixing bowl, combine the vanilla cake mix, eggs, and water. Beat with an electric mixer on medium speed for 2 minutes until smooth.
Pour the batter into the prepared baking dish and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool in the pan for 10 minutes, then remove and place it on a wire rack to cool completely.
Once the cake is cool, use the handle of a wooden spoon or a skewer to poke holes all over the cake, about 1 inch apart.
In a separate bowl, whisk together the heavy cream, sweetened condensed milk, and vanilla extract until well combined.
Slowly pour the cream mixture over the poked cake, making sure to fill the holes. Allow the cake to soak for at least 30 minutes or overnight in the refrigerator for best results.
After the cake has soaked, spread a layer of whipped cream evenly over the top of the cake.
Arrange the sliced strawberries on top of the whipped cream, adding as many as you like for a vibrant presentation.
Optionally, add fresh mint leaves as a garnish for a touch of color and flavor.
Notes
Serve chilled in squares with a drizzle of strawberry syrup on the plate for added flair.
