Preheat oven to 350 degrees F. Generously coat a standard size 12-cup muffin pan with nonstick cooking spray.
Gently roll out the pie crusts. Cut circles with a cookie cutter or glass with a 3.5-inch diameter. (You should be able to get 6 circles from each crust if you cut close to the edges and close to one another. See photo.)
Carefully press the dough rounds into each muffin slot. (The dough should come up about halfway in each muffin well.)
In a medium mixing bowl, whisk together the brown sugar, granulated sugar, melted butter, beaten egg, corn syrup, vanilla extract, a pinch of salt, and chopped pecans. Mix until thoroughly combined.
Fill each pie crust with 1 1/2 tablespoons of the filling (it won’t look like a lot, but the filling expands while baking.)
Bake for about 25 minutes (or when the center of pies start to solidify and are no longer jiggly.)
Cool completely in pan.
Gently run a dull knife around the outer crusts to loosen any parts that might be stuck, and using the same knife remove the pies from the pan.
Serve and enjoy!
