Lift your oven's top rack to its highest position and turn the broiler on high.
Line your rimmed baking dish with parchment paper and set asside.
Melt butter in a small saucepan or in a microwave-safe bowl.
If you purchased a loaf of angel food cake, using a serrated knife slice it into thick slices, approximately 2 inches thick. If your angel food cake is round you will make your slices the same thickness and make your cuts straight across the entire cake. Most often, we slice round angel food cake into wedges, but that will not work because they will not brown evenly under the broiler. Tip: Rinse and dry your knife between slices.
This is an optional step: Cut slices with a round cookie cutter.
Place cake slices onto your parchment paper-lined baking sheet. Using a baking brush, brush butter onto first one side of cake slices and then turn and brush the other side of cake with butter.
Place baking sheet under the broiler until cake slices are golden-brown. Note: You'll need to watch closely and rotate the tray to obtain even results. Remove tray from the oven, carefully turn cake slices, and return to the broiler until golden-brown.Note: Watch your cake because it will burn quickly. Arrange toasted slices onto individual serving plates. Spoon fruit pie filling onto each slice (or fresh fruit) and top with maple-cinnamon whipped cream. Serve and enjoy!!
