Preheat the oven to 350 degrees

Mix the butter, and cream cheese until well blended

Add flour, and mix in until a soft dough forms

Roll the dough into 1 inch balls, and place each one into greased cups of a mini muffin tin pan

Press the dough in the center with your thumb, and press the sides up to the top of the muffin tin cups

Moving on to the filling,

Combine the melted butter, brown sugar, egg, vanilla, and pecans

Use a spoon to fill each pastry cup with some filling - level to the top of the pastry shell

Bake for 20-25 minutes, or until the pastry is golden brown

Cool for a few minutes

Use a knife to loosen any filling from the edges of the pan, and invert muffin tin to release the pastries
