Prepare the Brownies: Preheat your oven to 350°F (175°C). Grease or line an 8x8-inch baking pan with parchment paper. In a large bowl, mix the strawberry cake mix, melted butter, eggs, and strawberry gelatin until a thick batter forms. Spread the batter evenly into the prepared pan and bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean. Allow to cool completely.

Make the Cream Cheese Frosting: In a medium bowl, beat the softened cream cheese and butter together until smooth. Mix in the vanilla extract and powdered sugar, beating until fluffy. Add heavy cream, one tablespoon at a time, until the frosting reaches a spreadable consistency.

Prepare the Strawberry Crumble: Crush the Golden Oreos into fine crumbs using a food processor or by placing them in a zip-top bag and crushing with a rolling pin. Mix the crumbs with melted butter and strawberry gelatin until evenly combined.

Assemble the Brownies: Spread the cream cheese frosting evenly over the cooled brownies. Sprinkle the strawberry crumble mixture generously over the frosting, pressing gently to help it adhere.

Serve and Enjoy: Cut into 16 squares and serve. Store leftovers in an airtight container in the refrigerator for up to 5 days.
