Prepare the yogurt mixture: In a medium bowl, combine Greek yogurt, honey (or maple syrup), vanilla extract, and cinnamon. Stir until smooth and well combined.
Prepare the berries: Wash and dry all berries. Hull and slice strawberries. If using frozen berries, thaw completely and drain excess liquid.
Toast nuts (optional): If desired, lightly toast almonds or walnuts in a dry skillet for 2-3 minutes until fragrant.
Assemble the parfaits: In clear glasses or bowls, create layers:
Start with 1/4 cup yogurt mixture at the bottom
Add 1/4 cup mixed berries
Sprinkle 2 tablespoons granola
Repeat layers once more
Finish and serve: Top with remaining berries, toasted nuts, chia seeds, and a drizzle of honey. Garnish with fresh mint if using.
Serve immediately: Enjoy right away or refrigerate for up to 2 hours before serving.
