Easy Vegan Dirt Pudding

0 Make the pudding first. In a medium sized sauce pan, whisk together the sugar, cocoa powder, cornstarch and salt, thoroughly, making sure there are no lumps of cornstarch left. 
1 Pour in the non-dairy milk and whisk to fully combine.
2 Heat the sauce pan on medium high and whisk constantly. Bring to a simmer, reduce heat to medium low. Let simmer, whisking every 10 seconds or so. 
3 Let the pudding simmer until it is nice and thick. About 6 to 8 minutes. Turn off the heat.
4 Add the vegan butter and vanilla into the sauce pan and then whisk until the butter has melted into the pudding.
5 Let the pudding cool at room temperature for about 30 minutes, then cover and put in the fridge until it is completely chilled. About 3 to 4 hours or overnight. It will thicken more as it cools.
6 Once the pudding is cold, make your dirt pudding. Taking 4 small cups, layer 2 to 4 tablespoons of pudding at the bottom of a cup, top with some of the crushed chocolate cookies, another layer of pudding, another layer of cookies and then a few gummy worms. Repeat with the remaining cups.
7 Serve immediately or let chill until ready to eat! Top with a little vegan whipped topping if desired.
