Prepare the Cake:
Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish.
Prepare the vanilla or white cake mix according to the package instructions. Bake in the prepared dish and allow the cake to cool slightly.
Poke and Fill:
Using the handle of a wooden spoon, poke holes evenly across the cake.
In a small bowl, mix the strawberry gelatin with 1 cup of boiling water, stirring until dissolved. Add the cold water and mix well. Pour the gelatin mixture evenly over the cake, letting it seep into the holes. Refrigerate for 1 hour to set.
Prepare the Topping:
In a mixing bowl, whisk together the vanilla pudding mix and cold milk until thickened, about 2 minutes. Gently fold in the whipped topping until smooth. Spread the topping evenly over the chilled cake.
Make the Crunch Layer:
In a food processor or resealable bag, crush the freeze-dried strawberries and Golden Oreos into small crumbs. Add the melted butter and mix until combined.
Sprinkle the crunch mixture evenly over the cake.
Chill and Serve:
Cover the cake and refrigerate for at least 1-2 hours before serving to allow the flavors to meld. Slice and enjoy!
