1-First, preheat your oven to 350°F to get it ready for baking. Crush the vanilla sandwich cookies, including the filling, into very small crumbs using a food processor or by pounding in a sealed bag. Place the crumbs in a bowl and add the strawberry gelatin powder (dry, without water) and melted butter, then stir to combine for a uniform mixture.

2-Next, spread the mixture in a thin layer on a baking sheet lined with parchment paper or a silicone mat. Bake for 8 minutes, keeping an eye on it to ensure even crisping. Once done, remove from the oven and let it cool completely to achieve that perfect crunchiness.
