n a large bowl, mix your flour and salt

Then mix in your butter and shortening with a pastry cutter or your fingertips making sure that there aren't any large clumps

Add two tablespoons of water in at a time and continue to mix until you have a thick non sticky dough

Wrap in wax paper and refrigerate for 15-20 minutes

Preheat your oven to 400 degrees and grease a baking pan with a non stick cooking spray

Roll your dough to about 1/8" onto a lightly floured surface and use your large heart cookie cutter to cut your shapes out

Scoop a good amount of Nutella in the center of half your dough hearts and place the other half on top

Use a fork to press your edges together, turn your hearts over and repeat

Use your finger to rub a small about of egg onto the edges to help them stick together

Bake for 50 minutes or until lightly golden

Let cool, they will be very hot, and enjoy!
