In a small saucepan, combine diced strawberries, butter, lemon juice, and sugar. Cook over low heat, stirring occasionally until the mixture thickens, about 5-10 minutes. Remove from heat and let it cool.
Transfer the cooled strawberry mixture to a mixing bowl and place it in the refrigerator to chill further.
In a large mixing bowl, combine cream cheese, Greek yogurt, vanilla protein powder, and the cheesecake flavored Jello packet. Mix until smooth and well combined.
Once the strawberry mixture is cooled, gently fold it into the cheesecake batter until evenly incorporated.
Divide the cheesecake mixture equally into 4 serving containers.
Crush one graham cracker and sprinkle it over each individual serving just before serving.
Chill the cheesecakes in the refrigerator for at least 1 hour before serving.
Enjoy the creamy goodness of your homemade Strawberry Cheesecake!
