Can I make this ahead of time?
Yes. Assemble the cheesecake, cover, and refrigerate up to 2 days before serving. Add banana slices and Biscoff crumble garnish just before serving to prevent sogginess.
What can I use instead of cottage cheese?
Greek yogurt (plain, full-fat) works well and maintains the protein content. Use equal parts. Ricotta is also an option but will be slightly grainier.
Is there a dairy-free version?
Substitute cottage cheese with silken tofu and use non-dairy whipped topping. The texture will be slightly lighter but still creamy.
How do I prevent the cheesecake from being lumpy?
Blend or food-process the cottage cheese until completely smooth before mixing in other ingredients. Blend again after adding vanilla and protein powder.
Can I use a different cookie for the base?
Yes. Digestive biscuits, graham crackers, or vanilla wafers work as alternatives, though you'll lose the Biscoff spice flavor profile.
