Stir the base: In a medium bowl or jar, whisk 1 cup unsweetened non-dairy milk, 2 tablespoons natural peanut butter, 1–2 teaspoons maple syrup, 1/2 teaspoon vanilla extract, and a tiny pinch of salt until smooth.
If the peanut butter clumps, warm it slightly or whisk a small splash of milk into the peanut butter first to loosen it.
Add chia seeds: Stir in 3 tablespoons chia seeds. Whisk well so no seeds clump at the bottom or stick together.
Rest and re-stir: Let the mixture sit for 10 minutes, then whisk again to break up early clumps. This step helps achieve an even, creamy texture.
Chill to thicken: Cover and refrigerate for at least 2 hours, ideally overnight.
The pudding should be thick and spoonable.
Adjust thickness: If it’s too thick, stir in a splash of milk. If it’s too thin, add 1 teaspoon chia seeds and chill another 15–20 minutes.
Top and serve: Add sliced banana, fresh berries, a sprinkle of cinnamon, or a few cacao nibs for crunch. For extra protein, stir in a spoonful of protein powder when mixing the base.
