Mix the base: In a bowl or jar, combine 1 cup unsweetened almond milk, 2–3 tablespoons heavy cream (optional), 2 teaspoons vanilla extract, 1–2 tablespoons keto sweetener, and a small pinch of salt. Stir until the sweetener starts to dissolve.
Add chia seeds: Stir in 3 tablespoons chia seeds.
Mix well so no clumps form. Let it sit for 2–3 minutes, then stir again to break up any seeds stuck together.
Chill: Cover and refrigerate for at least 2 hours, preferably overnight. The pudding will thicken as the seeds absorb the liquid.
Adjust thickness: If it’s too thick, whisk in more almond milk, 1 tablespoon at a time.
If it’s too thin, stir in 1 teaspoon more chia seeds and chill another 20–30 minutes.
Serve: Spoon into bowls and top with a few raspberries, a dusting of cinnamon, or a dollop of whipped cream. Taste and adjust sweetness if needed.
