Preheat the oven to 325°F and line a muffin tin with paper liners.
In a mixing bowl, beat cream cheese and Greek yogurt until smooth.
Add eggs one at a time, mixing well after each addition.
Stir in protein powder, honey, vanilla extract, and salt until combined.
Divide mixture evenly into muffin liners.
Bake for 18-22 minutes, until centers are just set.
Cool completely, then refrigerate at least 2 hours before serving.
Top with fruit, granola, or a drizzle of chocolate if you’d like.
