Preheat your oven to 350°F. Line an 8x8-inch baking dish with parchment paper or lightly spray with non-stick cooking spray.
To make the base
In a large mixing bowl, combine the strawberry cake mix, melted butter, eggs, and strawberry gelatin powder. Mix until fully combined (the batter will be thick).
Spread the batter evenly into the prepared baking dish.
Bake for 25 minutes, then remove from the oven and allow to cool completely.
For the frosting / creamy center
In a large mixing bowl, use an electric mixer to beat together the cream cheese, softened butter, and vanilla extract until smooth.
Add the powdered sugar and 1 tablespoon of heavy cream. Beat until fully combined and smooth. If needed, add another tablespoon of heavy cream to reach the desired consistency.
Spread the frosting evenly over the cooled strawberry base.
To make the crunch topping
Place the Golden Oreos in a food processor and pulse until broken into crumbs or crush the cookies in a zip loc bag.
Add the strawberry gelatin powder and combine.
Pour in the melted butter and pulse or mix until the mixture comes together.
Sprinkle the cookie crumble evenly over the cream cheese layer.
Refrigerate the bars for at least 30 minutes to help the layers set before slicing and serving.
Notes
Storage Guidelines
Store in an airtight container in the refrigerator for up to 5 days.
Freeze for up to 2 months and thaw in the fridge before serving.
Flavor Twists
Swap strawberry cake mix for vanilla or lemon for a different flavor profile.
Use crushed graham crackers instead of Oreos for a less sweet topping.
