In a food processor (you can also do this by hand if needed), combine the flour, cocoa, sugar, and salt on low until blended. Add the butter and Crisco and pulse until the mixture resembles coarse crumbles. Add the egg yolks and iced coffee and process with slow pulses until the dough forms a ball. Start with about 5 tablespoons of iced coffee and add more until the mixture comes together.
Press the dough into two flatten discs. Wrap in plastic and refrigerate for at least 30 minutes.
Then, preheat your oven to 350 degrees F.
On a floured surface, roll out your dough until it is about 1/8 inch thick. Then cut out the dough using a flour shaped cookie cutter. My cookie cutter is 3-inches in diameter petal tip to petal tip. Once your first set of flowers are cut, you can ball up the dough and roll it out again. Repeat until you have used as much of the dough as possible.
Gently press the flowers into an ungreased mini muffin pan. Bake at 350 degrees F for 12 -15 minutes.
Allow the mini pie shells to cool completely in the pan before removing. This will ensure they keep their shape.
While they are cooling, mix up the peanut butter pie filling. Beat the peanut butter with the cream cheese and vanilla until smooth. Then add the powdered sugar, beating again until smooth. Add in the Cool Whip and beat the mixture one final time until smooth.
Add this filling into a piping bag or large plastic bag. Pipe into your cooled chocolate pie shells.
For the drizzle, melt the chocolate chips and shortening in a microwavable bowl (or in a double broiler). Allow the mixture to cool slightly, then transfer to a plastic bag. Snip off a tiny portion of one corner of the bag and drizzle the chocolate onto the filled pie shells. Top with chopped peanut for a garnish.
