Add the pie crust mix into a food processor with the cold/solid coconut oil. It is best to cut/break the coconut oil into a few large pieces first.
Quick pulse the food processor 10-20 times until the coconut oil and mix resemble coarse sand.
Add the ice cold water slowly (2 tbsp at a time) while continuing to pulse the mix, until the dough comes together.
Wrap / cover the dough and refrigerate for 20 minutes.
Preheat oven to 350 degrees Fahrenheit
Roll out to desired thickness and cut out heart shapes.
Bake for 20-25 minutes.
Meanwhile, add frosting ingredients into a small bowl and whisk together.
When the cookies have finished baking and cooled, frost and enjoy!
