Soften the cream cheese: Let it sit at room temperature for 15–20 minutes, or microwave in short bursts until spreadable. This prevents lumps.
Make the cheesecake base: In a mixing bowl, whisk the softened cream cheese until smooth. Add Greek yogurt, vanilla extract, lemon juice, sweetener, and a pinch of salt.
Whisk until creamy and fully combined.
Add protein powder: Sprinkle in the protein powder and whisk again. If the mixture becomes too thick, add a splash of milk to loosen it.
Stir in milk and chia seeds: Pour in the milk and whisk until smooth. Stir in the chia seeds, mixing well so they don’t clump.
Let the mixture sit for 5 minutes, then stir again to redistribute the seeds.
Optional crust layer: If using, press a thin layer of crushed graham crackers or almond meal “crust” into the bottom of jars. You can also skip this for a lower-carb version.
Portion and chill: Divide the pudding into 3–4 jars or bowls. Cover and refrigerate for at least 2 hours, ideally overnight, until thick and set.
Top and serve: Add berries, a swirl of jam, lemon zest, or cinnamon.
Taste and adjust sweetness if needed before serving.
