Whisk the base. In a medium bowl or large jar, whisk 1 cup unsweetened almond milk, 1/2 cup plain Greek yogurt, 1 scoop vanilla protein powder, 1–2 teaspoons maple syrup or honey, 1/2 teaspoon vanilla extract, and a pinch of salt until smooth.
Break up any protein powder clumps before adding the chia.
Add chia seeds. Stir in 3 tablespoons chia seeds, mixing well so no dry pockets remain. Let it sit for 5 minutes, then stir again to prevent clumping.
Fold in berries. Add 3/4 to 1 cup mixed berries. If using frozen berries, you can add them straight from the freezer; they’ll thaw and tint the pudding a pretty purple.
Chill. Cover and refrigerate for at least 2 hours, ideally overnight.
The pudding will thicken as the chia absorbs liquid.
Adjust texture. In the morning, give it a good stir. If it’s too thick, add a splash of milk. If it’s too loose, stir in 1 more teaspoon chia seeds and let it sit for 10–15 minutes.
Serve and top. Portion into bowls or jars.
Add extra berries, a spoonful of nut butter, chopped nuts, or a sprinkle of coconut for crunch and extra nutrition.
