Crush the chocolate sandwich cookies in a food processor until they resemble fine crumbs. Melt the butter and combine it with the crushed cookies until well mixed. Press firmly into the bottom of a 9x13 glass baking dish to create a solid crust layer.

In a medium bowl, dissolve the orange gelatin in 1 cup of boiling water. In another bowl, whisk together the vanilla instant pudding mix and 2 cups of milk until thickened. Carefully combine both mixtures until blended and set aside.

Beat the cream cheese and powdered sugar together until smooth. Fold in 2 cups of whipped topping and a few drops of food coloring for the cheesecake layer.

Spread the cream cheese mixture evenly over the crust, smoothing it out. Pour the orange gelatin mixture over the cream cheese layer.

Mix the remaining whipped topping with food coloring and spread it over the orange layer for a fluffy finish.

Cover with plastic wrap and refrigerate for at least 4 hours until set firm.

Slice into squares and garnish with Halloween-themed sprinkles before serving.
