Turtle Cookies

These are so decadent, so delicious, so, so good!  You have to make them!  It's a perfect treat. Enjoy!
-1/2 cup (1 stick) unsalted butter, at room temperature
-2/3 cup sugar
-2 large eggs, divided
-2 Tbs milk
-1 tsp vanilla extract
-1/4 tsp salt
-1/3 cup unsweetened cocoa powder
-1 cup flour
-1 cup pecans, finely chopped
-14 soft caramels candies
-3 Tbs heavy cream
Cream butter and sugar until nice and fluffy.  Add one yolk, keeping the white in a small bowl in the fridge until ready to use. Stir in the milk, vanilla, salt and cocoa powder.  Mix well.  Add the flour and mix until well incorporated.
Place bowl with dough in the fridge for one hour.
Preheat oven to 350 F.  Line 2 cookie sheet with parchment paper and set aside.
Remove dough from the fridge.
To the reserved egg white, add the second egg white.  Beat until frothy.  Place pecan crumbs into a shallow bowl.
Roll cookie dough into 1 inch balls.  Dip in egg whites, then roll in pecans.  Place on prepared cookie sheets and make an indentation with your thumb in the middle (make sure to not put a hole in the cookie ;) ).  Use the rest of the dough.
Bake cookies in preheated oven for 12-13 minutes.
Meanwhile, microwave the caramels and cream in a bowl for 1-2 minutes, stirring every 30 seconds until smooth.
Once the cookies are out of the oven, fill each indentation with 1/2 to 1 tsp of the caramel mixture.  Let cool completely on the cookie sheets.  Move onto serving platter and enjoy!
