Butter Tart Thumbprint Cookies

This is, hands down, the most delicious and addictive cookie I have ever created! And by gawd it better be, given that it has been at least 2 years in the works! But consider this a warning… you will not be able to stop eating them (even if you freeze them)! These Butter Tart Thumbprint Cookies are filled with ooey gooey rich butter tart filling, nestled in a pecan sugar cookie. If you don't love raisins, you can easily substitute pecans in the filling. But if you love butter tarts, you will love this scrumptious cookie with an easy butter tart filling!
