The biscuits are processed into crumbs in a food processor to create the biscuit base. Alternatively, gently wrap the biscuits in a dish or sandwich bag. Add baking spread or melted butter, stir, and then compact and level the batter into the baking pan. Place in the refrigerator to chill.
Combine the cream cheese, icing sugar, and caramel sauce to make the filling by using an electric hand whisk or a food mixer with a whisk attachment. Double cream should be incorporated after the batter is quite thick and keeps its shape.
Over the biscuit base, pour the filling into the tin and level it evenly. Set in the refrigerator for at least four hours or overnight.
Throw the salted caramel sauce in a bowl and heat it in the microwave for 15 seconds, or until it can be poured, then pour it over the cheesecake to serve and decorate. If it does not spread or drip sufficiently, use a palette knife to smooth it out and push it to the edges.
Serve right away, put any leftovers in the refrigerator, and consume within two to three days.
Note: You can add toppings of your choice such as pecans and apples.
