Pistachio Chocolate Cups - Can be made Vegan!

I made these for my son-in-law, had to try it Vegan!  They loved them.  Super easy.  I cannot take credit for this recipe.  I borrowed it from Grandma's Kitchen.  It's a great add to any Christmas collection!  To make these you will need:
1 cup shelled pistachios (reserve a few nuts to just chop into chunky pieces for garnish on top of the pistachio chocolate cups.)
3/4 teaspoons salt (or to taste)
3 teaspoons vegetable oil
small paper cups
2 tablespoons butter , melted (Vegan - Earth Balance)
1/8 teaspoon salt
1/2 cup icing sugar (powdered sugar)
Chocolate Cups
18 oz. melting chocolate (**Vegan - either Carob or Mega Chips)

1. Preheat the oven to 300 degrees F.
2. Using a baking sheet, spread the shelled peeled pistachios out, leaving space between the nuts and roast them,. You will need to stir them a little while they are roasting, to turn them a little.  If you smell them, remove them from the oven.  When toasted, take out of the oven and let them cool down. Time depends on your oven, but 10-15 minutes usually.
3. Put the pistachios into a food processor and process until the nuts turn into a smooth consistency. Drizzle in the oil while the nuts are being ground. Keep processing until smooth. The pistachio paste is now ready for making the Pistachio Butter Filling.
4. Put the pistachio paste, 2 tablespoons butter, and salt into a mixing bowl and mix until well combined, add the powdered sugar and stir in until smooth.
5. On a tray place out some small paper cups. This should make approximately 30.
6. Melt the chocolate in a heatproof bowl in the microwave in 15 seconds increments.
7. Into each mini paper lined cup, drop in about a teaspoon of the melted chocolate, the next layer is a teaspoon of pistachio butter and then top it off with another teaspoon of chocolate.
8. If you like you can decorate them with a few pieces of chopped Pistachio nuts.
9. Refrigerate on a tray and when they are set store them in an airtight container in your fridge.
