Place Tart Shells on cookie sheet (I lined mine with foil for ease of clean up, as sometimes the tarts boil over a little) and place raisins in the bottom - you your discretion for the amount. Love raisins? Then load them up!
Cream butter and brown sugar in a bowl until light and fluffy.
Beat in egg and vanilla.
Blend in Maple Syrup and Corn Syrup. Then pour mixture into tart shells.
Bake at 375 F (190 C) for 15 to 20 minutes, or until golden brown.
Enjoy!
