Frequently Asked Questions

Can I make this cake without cornstarch?

Yes. Simply replace it with additional oat fiber or skimmed milk powder. This version is more suitable for the Attack Phase.

Why did my cake sink after baking?

This usually happens if the oven door is opened too early, the batter is overmixed, or the cake is removed from the oven before it’s fully baked.

Can I use Greek yogurt instead of quark?

Yes. Fat-free Greek yogurt works well and produces a slightly softer texture.

Can I freeze the cake?

Absolutely. Slice it first, wrap individual portions, and freeze for up to two months.

Is this recipe suitable for weight loss?

It can fit into a calorie-controlled eating plan thanks to its high protein content and lower carbohydrate profile, but weight loss depends on your overall diet and lifestyle.

Can I add cocoa?

Yes. Replace 1–2 tablespoons of oat fiber with unsweetened cocoa powder for a delicious chocolate version.
