How to Make Lemon Blueberry Keto Cheesecake Fluff

  • Prepare the whipped cream. Beat the heavy whipping cream in a bowl until stiff peaks form. Set aside when done.
  • Prepare the cream cheese mixture. In a separate bowl, beat the cream cheese together with the stevia (or another low carb granulated sweetener) until creamy. It’s best to use room temperature cream cheese for this.
  • Add the other ingredients. Add the fresh blueberries, lemon zest, and pure vanilla extract and beat to combine.
  • Add the whipped cream. Gently fold in the heavy whipped cream.
  • Prepare the serving glasses. Either spoon or pipe the fluff into 4 small serving glasses.
  • Serve. Top with extra blueberries and serve immediately.

Can I Make Cheesecake Fluff for Later?

You can definitely make this cheesecake fluff in advance to enjoy later if you want.

Simply make the recipe as per normal and then instead of adding the cheesecake fluff into serving glasses, transfer it into airtight containers instead. You’ll be able to keep cheesecake fluff stored in the fridge like this for up to 5-7 days.

Alternatively, if you would rather freeze your fluff, you can do that as well. Cheesecake fluff can be frozen for up to 3 months without issue.

  1. Absolutely LOVE this and can’t wait to try the others! Thanks for sharing it with us.

  2. Very delicious!
    I wanted to try this so bad. I didn’t have blueberries on hand but I had a ton of frozen raspberries (which worked for me as raspberries have less carbs than blueberries.) I let them thaw for about a half hour on the counter before using.
    It turned out fantastic, albeit a tiny bit thinner in consistency than yours appeared.
    Thank you for sharing this recipe.
    Can’t wait to try it with the fresh blueberries and other varieties you mentioned.

  3. This is delicious stuff. Mine doesn’t look quite as pink in color. Maybe my blueberries weren’t quite as juicy. But this tastes really great!!

  4. I have been struggling to find recipes that don’t require things I don’t have on hand that are still delicious! My biggest keto issue is cost! That said, today I made this for the first time, I omitted the lemon zest, which I’m sure would make this even more amazing. However, even without it, I’d give this more stars if I could! Amazing recipe, even my non keto family loved it! I highly recommend this to everyone!!! Thank you for a fantastic recipe!
