i got some problem here, today i tried to make oreo cheesecake but it turns out bad, the cake became quite creamy, just like ice cream. i use the non-bake method but i don't have fridge so i put it in the freezer after 2 hours the mixture already harden but it was not "hard", the cake filling felt like jelly. it was also hard to took it out from the pan because it's quite sticky to the pan. and if i put it at room temp it will melt anyone can figure out which step i've done it wrong?

the ingredients i use

for base
120 g blended oreo
120 g butter (should it melt in room temp or melt as liquid?)

for filling
2 egg yolk
120 g sugar
160 ml milk
250 g cream cheese
2 1/2 teaspoon melted in 6 teaspoon boiled water
250 g whipping cream
1/2 lemon juice
cream form Oreo biscuits

tomorrow i wanna try using oven, dunno succeed or no

thanks~
