This is my 'go to' cookie to make the crust when I don't feel like splurging for real Graham Crackers. As far as cheesecake being expensive, I agree. However the only ingredient that's expensive is the cream cheese and I use only Philadelphia as I think it tastes the best. I typically buy a 2kg block and make 2 cheesecakes. The second is either frozen or distributed to neighbors and friends.
BTW, these 'go to' cookies are found nearly everywhere and typically cost less than 40THB. but it does take about 1 1/2 pkgs for each cheesecake.
