  1. In a bowl, mix all ingredients with a fork or a balloon whisk. Whisk until there are no lumps.

  2. Lightly grease 2 ramekins with oil or melted butter (I used light olive oil, but coconut oil also works).

Chef's Notes

Net carbs: 2.6g per portion.
My microwave is 900 W. Adjust the cooking time according to the power of your microwave. 
My ramekins had a capacity of 6 ounces and had a diameter of 7 cm at the bottom and 9 cm at the top. 
This is a gently sweet dessert. Add an additional tablespoon of erythritol or a few drops of vanilla or lemon stevia if you prefer a sweeter cheesecake.
To add a cheesecake crust, mix 5-6 tablespoon almond flour, 1 teaspoon sweetener and 1 teaspoon melted butter until you have a crumbly mix. Press into the bottom of the greased ramekins and proceed as per recipe.  This increases the net carbs to 3.9g / 318 calories per serving.
To make these cheesecakes in the oven, try 160 C / 325F for 10-12 minutes.

I love , l o v e , LOVE this recipe! So delicious and quick, but looks like you've taken the time to make something special ;-)
I sometimes put in extra lemon juice and some ginger, grated orange zest, or whatever berries need using. It's such a versatile base. Thanks very much Katrin x

Made this twice (so ate it 4 times!) Absolutely delicious ! Only drawback is that I have to wait out the time in the fridge ‍♀️‍♀️ Worth it every time though!

LOVE the KETO MICROWAVE MUG CHEESECAKE for something sweet in the evenings! Really delicious, creamy and indulgent! Thanks Olivia xx

Is there any reason why you couldn’t use a hand mixer? It took me quite a bit of stirring with a fork to get out all the lumps. I used the baking method since I don’t use the microwave. I used 1 tablespoon Allulose and 1 tablespoon powdered swerve. topped it with whip cream and blueberries. It was delicious.

I used around 250g ricotta. It came out something like halfway between a pannacotta and a set custard. Beautiful.

Connie ★ 5.0/5

I had another recipe for Keto cheesecake that had butter and almond flour and it was just OKAY. I love this one so much better and it's so simple. My husband never tries my Keto snacks, but he saw that small cheesecake with a couple of strawberries and a little whipped cream and he asked to try it. He never does that. He liked it.

I made this about an hour before dinner coz I was craving for something sweet. It was delicious and super easy to make!

Lisa ★ 5.0/5

It was so easy to make this recipe. It took like two minutes and it has to sit for a little while but it was totally worth it. You can put anything on top of it. I used homemade sugar-free cherry pie mix that I made and it was really good.
