This recipe is ideal for late-night cravings, quick desserts, or when you want something sweet without committing to a full batch.

The Secret to Creamy Keto Cheesecake Texture
Microwave desserts can sometimes turn out spongy or overcooked, but this recipe avoids that entirely by balancing fat, moisture, and gentle cooking time.
Key texture secrets include:
- Full-fat cream cheese for richness
- Sour cream for softness and tang
- Powdered sweetener for smoothness
- Short microwave bursts to prevent overheating
Instead of becoming cakey, this cheesecake stays lush and custard-like, setting more as it cools.
Ingredients
- 4 oz full-fat cream cheese, softened
- 2 tbsp powdered erythritol or monk fruit sweetener
- 1 large egg
- 1 tbsp sour cream
- ½ tsp vanilla extract
- ½ tsp lemon juice (optional, for tang)

Instructions
- Place softened cream cheese in a microwave-safe mug.
- Add powdered sweetener and mash until completely smooth.
- Mix in the egg until fully incorporated and creamy.
- Stir in sour cream, vanilla extract, and lemon juice if using.
- Microwave on high for 60 seconds.
- Check texture and microwave in additional 10–15 second intervals if needed until just set.
- Allow to cool for 2–3 minutes; cheesecake will firm up slightly as it rests.
- Enjoy warm or refrigerate for a chilled cheesecake texture.

Microwave Timing Tips (Very Important)
Microwaves vary in strength, so timing matters:

- Center should look slightly soft, not liquid
- Overcooking leads to rubbery texture
- Cheesecake continues setting as it cools
It’s better to slightly undercook than overcook.
