Low-Carb Cheesecake Mug Dessert

Although this mug dessert takes longer due to the chilling time, it’s actually a bit easier to make than the others. There’s no almond flour or coconut flour to mess with and fewer ingredients than most of the other mug cakes.

This cake is also different in that it makes two servings instead of the typical single serve portion. It’s the perfect dessert for a keto date night! Share the second one with a friend or save it for another day.

I love having this recipe as a base to play around with toppings and mix-ins, too. That creamy cheesecake flavor goes so well with so many other flavors!

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.

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.
