Soften the cream cheese. Let it sit at room temperature for 20–30 minutes. Softer cream cheese blends smoother and avoids lumps.
Blend the base. In a high-speed blender or food processor, add Greek yogurt, cottage cheese, and cream cheese. Blend until completely smooth and silky.
Scrape down the sides as needed.
Add flavor and protein. Add protein powder, vanilla extract, lemon juice, lemon zest if using, and a pinch of salt. Blend again until fully incorporated.
Sweeten to taste. Add your preferred sweetener a little at a time. Blend, taste, and adjust so it’s pleasantly sweet but not overly sugary.
Cheesecake flavor pops when sweetness is balanced.
Thicken it. For instant pudding mix: sprinkle it in while the blender runs on low, then pour in 1/2 cup milk and blend. For gelatin: bloom 1 packet in 1/4 cup cold milk for 5 minutes, then gently warm until dissolved and stream it into the blender with another 1/4–1/2 cup milk as needed. You’re aiming for a thick, pourable texture.
Chill to set. Pour into a bowl or individual jars.
Cover and refrigerate at least 2–4 hours, or overnight for best results. It will firm up as it chills.
Finish and serve. Stir to loosen if it’s very firm. Top with berries, a sprinkle of crushed grahams, or a few chopped nuts for crunch.
Serve cold.
