Mix the butter and sugar together until smooth and then add the flour, mixing until well combined. Pat down along the bottom and sides of two pie plates. Bake at 350 for 12-15 minutes, or until very lightly golden brown. Let cool while making the filling.

In a medium saucepan, add sugar and cornstarch to Sprite and whisk together over medium-high heat. Bring the mixture to a boil, stirring constantly. Boil until the mixture starts to go clear and thicken up while continuing to stir.

Add the Jell-O and boil for one minute longer. Remove from heat and let the mixture cool for about 20 minutes. (If you want the color to be slightly more intense, you can add a few drops of yellow food coloring at this point.)

Add the peaches to the filling mixture and stir gently just until combined. Pour the filling into the prepared pie crusts and put in the refrigerator to set up. The pies will take about 6 hours to fully set. Enjoy!
