Preheat the oven to 350 degrees Fahrenheit. Spray a 15x10x1 pan with pan spray and set aside.
Cream together butter and sugar. Add eggs and beat well. Beat in extracts.
In a separate bowl, combine the flour and salt. Add the flour mixture to the creamed mixture. Mix until combined.
Spread 3 cups of batter on the bottom of the prepared pan. Top with the cans of cherry pie filling, spreading evenly across the batter. Drop dollops of the remaining batter as evenly as possible over the top until all the batter has been used.
Bake for 30-35 minutes or until a toothpick comes out clean. If using a 9x13 pan instead, the cook time may end up being quite a bit longer to get a toothpick to come out clean. Cool completely.
Whisk together the glaze ingredients and drizzle over the cooled bars.
