In a medium bowl, cream butter with softened cream cheese. Next, add the flour. Mix until completely combined. It will be very sticky.
3 ounces cream cheese, ½ cup butter, 1 cup all-purpose flour
Wrap dough in wax paper or plastic wrap and chill for at least an hour.
When you are ready to make the tarts, preheat your oven to 325°F, then make the filling.
Using an electric mixer, combine egg, softened butter, brown sugar, vanilla extract, and a pinch of salt until it makes a silky pie filling.
¾ cup light brown sugar, 1 egg, 1 tablespoon butter, 1 pinch kosher salt, 1 teaspoon vanilla extract
Spray a mini muffin pan with cooking spray or use your favorite “cute” muffin tin.
Take out the chilled dough and cut it in half - return half of the dough to the fridge to keep cold. (As the dough softens, it will get harder to work with.)
Divide each half of the dough into approximately 12 even dough balls.
Press one ball of dough into each of the cups of the greased muffin pan, covering the bottom and the sides of the cup, and using your fingers to press it down and smooth it out. (If you use unusually shaped pans, you might end up with a different amount of tarts. If you use a standard “mini” muffin tin, you should end up with 24 mini tarts.)
I like to chill the prepared dough again for about ten minutes before filling the cups (I just stick the whole muffin tin in the fridge), but if your house isn’t super warm, this step isn’t necessary.
Next, scoop about a teaspoon of chopped pecans into each muffin cup. (If you use an abnormally shaped pan, fill it to a little below the rim with pecans.)
⅔ cup pecan halves
Spoon the pie filling over the top, then bang the pan on the counter a few times to help the sugar seep in around the pecans.
Bake for 30 minutes, then let cool on a wire rack. (I like to let them sit for 5-10 minutes, then I use a butter knife to trace around the edges of the muffin cups to loosen the tarts. Then, they should pop right out.)
When the tarts come out of the oven, you will notice that some of the tarts will set perfectly, and some might look like they exploded and split open a doorway to another universe. Both will be very delicious.
Serve & enjoy!
