What about a smash base. I know it sounds boke but seemingly it's like pastry. Some ones have used it on pies and as pizza bases. I don't know the recipe but you could search for it I'm sure
i made the quark with options cheesecake and used 3 digestives and mixed them up with some icing sugar, and put in the fridge to set and then gave to my mum and dad and had some myself and they said it was amazing extremely sweet, maybe too sweet for me but was like a proper cheesecake xxx
I'm trying this now, but usingbwheetabix crunch as a healthy b and mix with some digestives and sweetener. Doing lemon topping not chic. Ill let u know
