Combine the sugar & cornstarch together in a heavy bottom sauce pot, then add the plant milk
Cook over medium heat stirring constantly with a whisk until it comes to a full boil. Allow it to bubble for about 5 seconds then turn off the heat & stir in the vegan butter & vanilla
*If you are using a vanilla bean you will split it and scrape it of it's seeds and boil the entire pod in the milk. Once it boils, remove the pod and dry it off, then add it to a bowl of granulated sugar tightly closed and use for vanilla sugar as the caramelizing sugar for the tops :)
Pour the custard into un-greased ramekins then refrigerate to set - this should only take about 15-20 minutes but can be refrigerated overnight
Once set, sprinkle approximately 1 Tablespoon granulated sugar lightly over the tops, NOT A THICK LAYER, then using a torch (according to the instructions on your particular model) caramelize the tops
Serve immediately.
