Choose your container: A mason jar or small lidded bowl works best. Make sure it’s large enough for stirring and some expansion.
Mix the base: Add the milk, sweetener, vanilla, and salt to the container.
Whisk or stir until the sweetener dissolves.
Add chia seeds: Sprinkle the chia seeds over the liquid while whisking to prevent clumps. Stir for 30–45 seconds to distribute evenly.
Optional richness: If using yogurt or cocoa, whisk it in now until smooth. Taste and adjust sweetness.
Let it sit briefly: Rest the mixture for 5–10 minutes, then stir again.
This second stir breaks up early clumping and ensures a consistent texture.
Chill: Cover and refrigerate for at least 2 hours, or overnight for maximum creaminess. The seeds will swell and thicken the pudding.
Stir and serve: Give it a final stir before eating. If it’s too thick, add a splash of milk.
Top with fruit, nuts, or a drizzle of nut butter.
