In a mixing bowl, combine the softened cream cheese and heavy whipping cream.
Use an electric mixer on medium-high speed to beat the mixture until smooth and slightly fluffy (about 3–5 minutes).
If desired, add a keto-friendly sweetener and mix well.
In small serving glasses or jars, layer about 2 tablespoons of the cheesecake mixture, then add a few blueberries on top.
Repeat the layers until the glasses are filled, finishing with a few blueberries on top.
For the best texture, chill the parfaits for 30 minutes before serving. Garnish with extra blueberries or a sprinkle of grated lemon zest if desired.
