Preheat your oven to 350°F (175°C). Combine the white cake mix, eggs, water, and oil in a mixing bowl. Blend until smooth and lump-free, about 2 minutes. Pour into a greased baking pan and bake for 25-30 minutes or until a toothpick comes out clean.

Let the cake cool in the pan for about 10 minutes. Poke holes all over the top using a fork or skewer, ensuring they are deep enough for the gelatin.

In a medium mixing bowl, combine 1 cup of boiling water with the strawberry gelatin powder, stirring until dissolved. Then add ½ cup of cold water and mix again. Let it cool slightly.

Pour the cooled gelatin mixture over the cake, ensuring it seeps into the holes. Cover with plastic wrap and refrigerate for at least 2 hours.

Spread the whipped topping over the set gelatin layer, smoothing it out evenly.

Add festive toppings like sprinkles, marshmallows, or chocolate eggs. Slice and serve chilled.
