Add the chopped strawberries to a small saucepan along with the lemon juice and place it over medium heat. As the strawberries warm up, they will begin to release their natural juices. Stir gently and allow them to cook for several minutes until the fruit becomes soft and slightly jam-like. Use the back of a spoon to lightly mash some of the strawberries for a thicker texture, but leave a few small chunks for freshness. Once the mixture looks glossy and naturally thickened, remove it from the heat and let it cool completely. Cooling is important so the warm fruit doesn’t melt or thin out the cheesecake layer later.

Place the softened cream cheese and Greek yogurt into a mixing bowl. Using a hand mixer or a sturdy whisk, beat the mixture until it becomes completely smooth and creamy with no visible lumps. This step sets the foundation for a true cheesecake-like texture, so take your time and scrape down the sides of the bowl as needed to ensure everything is evenly combined.

Add the protein powder, sweetener, and vanilla extract to the cream cheese mixture. Blend again until fully incorporated and silky smooth. Make sure the protein powder is evenly mixed in without any dry pockets, as uneven blending can cause a grainy texture. At this stage, taste the mixture and adjust sweetness if needed, keeping in mind that flavors become slightly more muted once chilled.

Take your serving jars or containers and begin assembling the layers. Spoon a layer of the cooled strawberry mixture into the bottom of each jar, spreading it evenly. Follow with a generous layer of the cheesecake filling, smoothing the top gently with the back of a spoon. Repeat the layers if your jars are tall enough, finishing with either the cheesecake layer or a thin strawberry layer on top for visual appeal.

Cover the jars and place them in the refrigerator for at least 2–3 hours to allow the cheesecake filling to firm up and the flavors to fully develop. For the best texture and flavor, chilling overnight is even better. Once set, the jars are ready to serve straight from the fridge as a creamy, refreshing, high-protein dessert.
