Soften the cream cheese: Leave it at room temperature for 30–45 minutes.
This step is key for a smooth, lump-free filling.
Make the chocolate base: In a mixing bowl, beat the softened cream cheese with a hand mixer until creamy. Add the Greek yogurt, cocoa powder, powdered sweetener, vanilla, and salt. Mix on low at first, then medium, until smooth and fluffy, scraping the bowl as needed.
Adjust consistency: Add almond milk 1 tablespoon at a time until the mixture is silky and spoonable but still thick.
Taste and adjust sweetness.
Optional crust: In a separate bowl, stir together almond flour, cocoa, melted butter, a small pinch of salt, and a little sweetener. Press a thin layer into the bottom of 4–6 small jars or ramekins.
Fill the jars: Spoon or pipe the chocolate cheesecake mixture over the crust (or directly into jars if skipping the crust). Smooth the tops.
Chill: Cover and refrigerate for at least 1–2 hours, or up to overnight, to set the texture and meld flavors.
Top and serve: Add fresh berries, a sprinkle of chocolate shavings, or a few crushed nuts just before serving.
