Chill your coconut can. Refrigerate a can of full-fat coconut milk overnight and scoop out the solid cream.
You want 1 cup of the thick stuff.
Whisk the base. In a mixing bowl, combine coconut cream, Greek yogurt, protein powder, vanilla, sweetener, and a pinch of salt. Whisk until smooth and glossy.
Taste and adjust sweetness.
Choose your thickener. Chia method: Stir in chia seeds and shredded coconut (if using). Whisk for 30 seconds to break up clumps. Let sit 10 minutes, then whisk again.
Gelatin method: Sprinkle gelatin over 2 tablespoons cold water and let bloom 5 minutes.
Dissolve with 1/4 cup hot coconut water or milk, stirring until clear. Whisk into the pudding base.
Portion and chill. Divide into 4 small jars or bowls.
Cover and refrigerate at least 2 hours. Chia will create a thicker, slightly seedy texture; gelatin sets smooth and custard-like.
Finish and serve. Stir briefly before serving.
Top with toasted coconut, fresh fruit, or a squeeze of lime. Keep extras chilled.
