Low-carb Mug Cheesecake Recipe Notes and FAQ
Can I skip the 3-hour chilling step?
This dessert must be enjoyed fully chilled or the egg taste will be prominent. Chill for at least 3 hours or overnight for the best results. You can speed up the process by flipping the mug cake onto a plate before chilling.

Here are some low-carb topping ideas to add flavor to your cheesecake:
- Melt keto chocolate chips for a drizzle
- Fresh berries like blueberries, raspberries, or strawberries
- Keto whipped cream
- Low-carb chocolate whipped topping
- You can also add chocolate chips or blueberries to the batter
If you choose to add toppings or mix-ins, be sure to factor them into your macros.

Why does this recipe have so much cream cheese?
There are other recipes out there with a lot less cream cheese. After sampling several of them, many taste like sweet egg and it’s not the ideal cheesecake flavor. By using more cream cheese, you get closer to that delicious cheesecake taste that you crave.
