Mix the base: In a bowl, whisk the Greek yogurt with vanilla, sweetener, and a small pinch of salt. Stir until smooth and lightly sweet.
Add protein powder: Sprinkle the protein powder over the yogurt and whisk until fully blended.
If it gets too thick, add a splash of milk or water to loosen.
Prep the fruit: Rinse and dry berries. Slice bananas or stone fruit. Pat fruit dry to reduce excess moisture in the parfait.
Layer smart: Spoon a layer of yogurt into a glass or jar.
Add a layer of fruit, then a light layer of granola and nuts.
Repeat: Continue layering yogurt, fruit, and crunch until you reach the top. Finish with a drizzle of honey or nut butter and a dusting of cinnamon or lemon zest.
Serve or chill: Enjoy right away for maximum crunch, or chill for 15–20 minutes if you like a colder, slightly set parfait.
