Soften and prep: Let the cream cheese sit at room temperature for 20–30 minutes. This helps it blend smoothly.
Blend the base: In a blender or food processor, add cream cheese, Greek yogurt, protein powder, sweetener, vanilla, lemon juice, and salt.
Pour in 1/3 cup milk.
Adjust texture: Blend until silky. If it’s too thick to pour, add milk 1 tablespoon at a time. Aim for a thick smoothie consistency that still flows.
Taste and tweak: Check sweetness and tang.
Add a little more lemon for brightness or sweetener for a classic cheesecake vibe.
Optional crust layer: Stir crushed graham crackers with melted butter until sandy. Spoon a teaspoon into each popsicle mold. Lightly press down.
Fill the molds: Pour the cheesecake mixture into popsicle molds, leaving about 1/4 inch at the top for expansion.
Tap the mold gently to release air bubbles.
Add mix-ins: If using berries, chips, or jam, add small amounts to each cavity and swirl with a skewer for ribbons.
Insert sticks and freeze: Add sticks and freeze for at least 6 hours, preferably overnight, until completely solid.
Unmold: Run warm water over the outside of the mold for 10–20 seconds. Wiggle the sticks gently to release.
Serve or store: Enjoy right away or transfer to an airtight container with parchment between layers.
