Preheat oven to 350°F. Grease a 13x9 inch baking dish with cooking spray.

In a large bowl, combine the white cake mix, one box of strawberry gelatin, eggs, vegetable oil, and water. Beat with a hand mixer for 2 minutes.

Pour into the greased pan, and bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean. Let cool completely.

While the cake is baking, crush the Golden Oreos into small crumbles. You can use either a food processor, or place the Oreos in a plastic bag and pound them with a meat mallet or rolling pin.

Place the crumbled Oreos in a medium bowl, and add one box of strawberry gelatin and 4 tablespoons melted butter. Mix gently to combine.

Spread the mixture onto a greased baking sheet (or top the baking sheet with parchment paper or a silicone mat first). Bake for 8 minutes at 350°F. Let cool.

Once the cake is cool, place the 4 tablespoons softened butter, softened cream cheese, powdered sugar, and 1 tablespoon of milk in a large bowl. Beat with a hand mixer until light and fluffy. Add an additional tablespoon of milk if the frosting is too stiff.

Top the cooled cake with the frosting, then sprinkle the strawberry crunch on top. Cut into slices and serve!
