In a medium saucepan, whisk together the almond milk, granulated sweetener, cocoa powder, cornstarch, and salt until smooth and well combined.
Place the saucepan over medium heat and cook, whisking constantly, until the mixture starts to thicken and just begins to bubble, about 5-7 minutes. Be careful not to let it boil vigorously to prevent the pudding from becoming lumpy. Once the mixture has thickened to the consistency of a soft pudding, remove from heat and stir in the vanilla extract.
Divide the pudding into serving dishes or a large bowl. To prevent a skin from forming on top, place plastic wrap directly on the surface of the pudding. Chill in the refrigerator for at least 2 hours, or until set. Before serving, you can whisk the pudding again for a smoother texture, if desired.
Tip:
For a creamier pudding, consider blending the chilled pudding in a blender until smooth and creamy. This can help achieve a silky texture. Garnish with a light sprinkle of sea salt, fresh berries, or a dollop of whipped coconut cream for added flavor and presentation.
