Chef's Helpful Tips
- For your Keto Cheesecake in a Mug, make sure to soften your cream cheese to room temperature for the best mixing results.
- Avoid using granulated sweeteners, as they won't blend as smoothly as powdered erythritol.
- When incorporating the egg, whisk it thoroughly to ensure a light and fluffy texture throughout the cheesecake.
- Keep a close eye on your microwave timing, as every microwave can vary; start with one minute and check for doneness before adding additional time in small increments.
Keto Cheesecake in a Mug Recipe FAQs
How do I select the right cream cheese for my recipe?
