Mash the raspberries: In a small bowl, mash the raspberries with a fork until they’re juicy with some small chunks left. If you prefer a smoother texture, press them through a fine strainer to remove seeds.
Whisk the base: In a separate bowl or jar, whisk the almond milk, vanilla, a tiny pinch of salt, and sweetener if using.
Taste the liquid now and adjust the sweetness so it’s just right for you.
Add chia seeds: Stir the chia seeds into the milk mixture. Whisk for 20–30 seconds to prevent clumping.
Combine with raspberries: Fold in the mashed raspberries (and lemon zest if using). Stir well so the berries are evenly distributed.
Rest and stir: Let the mixture sit for 10 minutes at room temperature, then give it another good stir.
This second stir helps break up any chia clumps for a smoother pudding.
Chill: Cover and refrigerate for at least 1–2 hours, or overnight for the thickest, creamiest texture.
Serve: Enjoy straight from the fridge. For extra flair while staying near 100 calories, top with a few fresh raspberry pieces or a dusting of cinnamon.
