Preheat oven to 350°F. Grease and flour 15x10x1-inch baking pan or 13x9-inch baking dish. Photo above was in a 13X9-inch baking dish.
In large bowl, combine all cake bar ingredients (cake mix, cherry pie filling, almond extract, and eggs);
Stir until well blended. You can use a stand mixer or stir by hand. A stand mixer will break up the cherries a bit more. Pour into greased and floured pan.
Bake at 350°F. until toothpick inserted in center comes out clean. For 15x10x1-inch pan, bake 20 to 30 minutes; for 13x9-inch pan, bake 25 to 35 minutes.
In small saucepan, combine sugar, milk and butter. Bring mixture to a boil and boil 1 minute, stirring constantly. Remove from heat; stir in chocolate chips and almond extract until smooth. Pour and spread over warm bars. Cool 2 hours or until completely cooled. You can speed up this process by placing them in the fridge to cool. Cut into bars.
