FAQs

Can I make this cookie in the oven?

Do I need collagen peptides?

No, you can omit them if you don’t have any. The cookie may be slightly less chewy but still delicious.

Can I use a whole egg instead of just the yolk?

Yes. Divide the dough into smaller portions and reduce cook time to about 6–7 minutes.

Are sugar-free chocolate chips keto?

Yes—use chips sweetened with stevia, monk fruit, or erythritol.

Can I double this recipe?

Absolutely! You can mix up a double batch and cook in separate rounds or store extra dough in the fridge.
