Start with the base: In a jar or container, add 1/2 cup rolled oats, 1 tablespoon chia or flax, a pinch of salt, and 1/2 teaspoon vanilla.
Add liquid: Pour in 1/2 to 3/4 cup plant-based milk. If using yogurt, add 1/4 cup and reduce the milk slightly so the mixture stays spoonable, not runny.
Sweeten lightly: Stir in 1–2 teaspoons of your chosen sweetener.
You can always add more in the morning.
Mix well: Stir until everything is evenly combined and the chia seeds aren’t clumped.
Add fruit: Fold in a handful of fruit. For berries or diced fruit, mix them in now. For banana slices, it’s best to add them in the morning so they don’t brown.
Chill overnight: Cover and refrigerate for at least 4 hours, preferably 8–12 hours, to let the oats soften.
Finish and enjoy: In the morning, give it a good stir.
Adjust thickness with a splash of milk. Top with nuts, seeds, or a spoon of nut butter for crunch and extra protein.
