Combine 2 cups oat milk, 2 cups raspberries, 1 cup yogurt, 1 tablespoon plus 2 teaspoons honey, 1 teaspoon lemon zest, 1 tablespoon lemon juice, ½ teaspoon vanilla and ⅛ teaspoon salt in a blender. Blend until smooth, about 30 seconds.
Transfer the mixture to a large bowl. Add 1 cup chia seeds; stir until slightly thickened, about 1 minute. Cover and refrigerate until fully thickened, at least 8 hours.
Divide the chia pudding among 4 jars or bowls. Garnish with additional raspberries and/or lemon zest, if desired.
