In a medium bowl, combine the crushed graham crackers and melted butter. Mix until the crumbs are evenly coated. Divide the mixture evenly among serving cups to form the crust at the bottom. Press down gently to compact it.
In a blender or food processor, add the cottage cheese, peanut butter, honey (or maple syrup), vanilla extract, powdered sugar, and lemon juice. Blend until smooth and creamy, scraping down the sides as needed.
Spoon the peanut butter mixture over the crust in each cup, filling them about three-quarters full.
If using, top each cup with whipped cream for added richness.
Refrigerate the cheesecake cups for at least 2 hours to allow them to set and chill before serving.
