Pick your container: Use 12–16 oz jars or lidded containers. Clear jars make layers pretty and help with portion control.
Make the base: In a bowl, combine 1 cup yogurt, 1/2 cup rolled oats, 2–4 tablespoons milk, and 1 teaspoon chia seeds.
Add a small pinch of salt and 1–2 teaspoons honey or maple syrup if you like it sweeter.
Flavor it: Stir in 1/2 teaspoon vanilla and a dash of cinnamon. For a chocolate version, mix in 1 teaspoon cocoa powder. Adjust milk for your preferred thickness.
Layer: Spoon half the yogurt-oat mixture into the jar.
Add a layer of fruit (about 1/3 to 1/2 cup). Top with the remaining mixture. Leave a little room at the top for toppings later.
Chill: Seal and refrigerate overnight (at least 6 hours).
The oats hydrate and the chia helps thicken everything.
Add crunch in the morning: Right before eating, add granola, nuts, seeds, or a drizzle of nut butter. This keeps the textures fresh.
Grab and go: Enjoy cold. If the parfait is too thick, stir in a splash of milk.
