In a large mixing bowl, combine the softened cream cheese and butter.
Using an electric hand mixer, beat on medium speed until light, fluffy, and completely smooth.
In a separate small bowl, thoroughly mash the strawberries with a fork.
Stir in the pure vanilla extract and liquid Stevia until well combined.
Add the strawberry mixture to the whipped cream cheese and butter.
Beat again on low speed until everything is just combined and the mixture has a uniform pink color.
Spoon the mixture evenly into 10 silicone muffin molds. Smooth the tops with a spatula.
Place the molds in the freezer and freeze for 3-4 hours, or until completely firm.
Once frozen, pop the cheesecake bites out of the molds.
Serve immediately or store in an airtight container in the freezer.
