FAQs
Can I use a different sweetener?
Yes, you can use any sugar-free sweetener you prefer. Just ensure it’s a 1:1 replacement for sugar to maintain the sweetness level.
Is there a dairy-free option?
To make this recipe dairy-free, substitute the cottage cheese with a dairy-free yogurt or silken tofu.
Can I use a different flour?
Almond flour is recommended for its low-carb content, but you can use coconut flour. Note that coconut flour absorbs more liquid, so use only 1 tablespoon.
How can I store leftovers?
This mug cake is best enjoyed fresh. However, if you have leftovers, store them in an airtight container in the refrigerator for up to 1 day and reheat gently in the microwave.
Can I add other flavors?
Absolutely! You can add a teaspoon of poppy seeds for a lemon-poppy seed variation or a splash of vanilla extract for added flavor.
