Roughly chop the dark chocolate into small pieces and set aside.
In a medium sized sauce pan, whisk together the cornstarch, sugar and cocoa powder.
Pour in the almond milk and whisk until smooth.
Place the pan on the burner over medium high heat. Cook, whisking constantly, until the mixture comes to a gentle boil and begins to thicken and has a pudding like texture. This will take from 5-6 minutes.
Once thickened, turn off the heat and stir in the chopped chocolate until fully incorporated. Immediately pour the pudding into glasses, ramekins or container of your choice as it begins to set as it cools.
Once slightly cooled, place plastic wrap directly on the pudding to prevent a skin from forming as it cools.
Refrigerate to let cool and set completely before serving, about 3 hours. Enjoy as is or garnish with fruit, chopped nuts or whipped cream.
