Calories213 kcal


  • ▢5 oz / 142g cream cheese
  • ▢1 egg, large
  • ▢2 tbsp powdered sweetener
  • ▢½ tsp vanilla extract
  • ▢½ tsp lemon juice
  • ▢1 tsp lemon zest


  • In a bowl, mix all ingredients with a fork or a balloon whisk. Whisk until there are no lumps.
  • Lightly grease 2 ramekins with oil or melted butter (I used light olive oil, but coconut oil also works).
  • Divide the batter between the ramekins. Microwave one ramekin at a time for 1 minute each on high. The tops should be glossy and the centre still jiggly. Then microwave each ramekin for a further 20 seconds.
  • Cool on the counter for 10 minutes, then cool in the fridge for circa 1 hour or until cool.
  • Eat straight from the ramekin or invert onto a plate and decorate with berries / whipped cream / a quick berry coulis.


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 tbsp 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 tbsp almond flour, 1 tsp sweetener and 1 tsp 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.
