Whisk together the flour, sugar and salt.
Using a pastry blender or two knives cut in the butter and shortening
Add 3 TBS of the ice water. Mix with a fork. If you need to add more water to get the dough to come together do so a teaspoon at a time.
Do not over mix.
Gather the mixture into a ball, remove to a surface lightly dusted with flour and knead a few times to form a cohesive dough.
Form into a disc, wrap in plastic and refrigerate for at least an hour.
Dust your surface with a little bit of flour and roll the dough out to about 1/8" thick.
Cut the dough into 2" rounds - I used a biscuit cutter. You can gather the scraps and reroll and cut.
Use a fork to prick the dough three times in the center.
Take a mini cupcake pan and spray the bottom with cooking spray. Take the dough round, and place it over the cupcake well with the side you pricked with fork facing down. Gently press the dough to fit around the form.
After you have fit the dough rounds on all of the cupcake wells (I had two mini cupcake pans) place in the freezer to chill for 15 minutes
While the dough chills preheat the oven to 350
Pull the mini cupcake pans from the freezer and bake for 12 minutes - but watch them at about 10 minutes as they turn very quickly.
Carefully remove from the pans and cool on a wire rack. Repeat as necessary until all of the dough circles have been baked.
