Start by preheating your oven to 350°F (175°C). In a mixing bowl, combine the flour, sugar, melted butter, eggs, and water, stirring until well blended. Pour this mixture into a greased cake pan and bake for about 30 minutes or until a toothpick comes out clean. Allow it to cool completely once baked.
While the cake is cooling, mix the strawberry Jello powder with the cold water according to the package directions until fully dissolved.
Once the cake has cooled, poke holes into the top using a fork or skewer, then pour the Jello evenly over the cake. Refrigerate for at least 4 hours, allowing the Jello to set and infuse into the cake.
To finish, spread the whipped topping over the set cake and top with freshly sliced strawberries. Cut into squares and serve chilled for a refreshing treat!
Notes
For extra flavor, consider adding a splash of vanilla extract to your cake batter!
