1. Prepare the Crust:
- Line a 9×9-inch baking pan with parchment paper, leaving an overhang on two opposite sides for easy lifting later.
- Preheat oven to 350°F (175°C).
- Finely crush 24 of the Golden Oreo cookies using a food processor or by placing them in a bag and crushing with a rolling pin.
- In a small bowl, mix the fine cookie crumbs with the melted butter until thoroughly combined.
- Press the crumb mixture firmly and evenly onto the bottom of the prepared pan.
- Bake for 15-20 minutes, or until the crust feels firm to the touch.
- Cool the crust completely on a wire rack.
2. Layer the Ice Cream:
- Once the crust is completely cool, spread the softened vanilla ice cream evenly over the crust.
- Cover the pan (with plastic wrap or foil) and freeze until the vanilla layer is firm, at least 30 minutes.
- Spread the softened strawberry ice cream evenly over the firm vanilla layer.
- Spread the thawed whipped topping evenly over the strawberry ice cream layer.
- Cover and freeze again until the whipped topping layer is firm, at least 2 hours.
3. Make and Add the Crunch Topping:
- Coarsely crush the remaining 12 Golden Oreo cookies. You want slightly larger pieces than for the crust.
- In a small bowl, combine the coarsely crushed cookies and the coarsely crushed freeze-dried strawberries.
- Sprinkle this crunch mixture evenly over the firm whipped topping layer. Gently press down slightly if needed.
4. Final Freeze:
- Cover the cake tightly and freeze until completely firm, ideally for 8 hours or overnight.
5. Serve:
- When ready to serve, remove the cake from the freezer.
- Using the parchment paper overhangs, lift the cake out of the pan.
- Gently peel off the parchment paper from the sides and bottom.
- Let the cake stand at room temperature for about 10 minutes to soften slightly for easier cutting.
- If desired, garnish with fresh strawberries. Slice and serve immediately.
