Oh right.
Cheesecake is one of those “funny” ones either you go for baking or chilled. Baked potentially nicer BUT they are supposed to be fluffy, so you should be whisking the egg whites to fold into your cream cheese egg yolk and sugar mix, beating it with a wooden spoon isn’t going to work, it’ll be dense and prolly collapse. Hand whisk?
Ginger biscuits are for children, you need ammeretti biscuits in your base with vanilla extract in your butter
Edit: if this is for tomorrow, you need to make it tonight, ok?
