Begin by preheating the oven to 350 degrees Fahrenheit.
Spray a 9 x 13-inch baking pan with non-stick cooking spray.
Next, empty the angel food cake mix and the lemon pie filling into a LARGE mixing bowl.
Stir the ingredients with a wooden spoon until totally combined.
After the two ingredients are completely incorporated into each other, pour the bar batter into the prepared baking pan. Use your wooden spoon to spread the batter to the edges, so that the pan is filled evenly.
Place the pan in the oven and bake for approximately 25 minutes.
Allow the bars to cool completely
Once cooled, you can sprinkle the bars with powdered sugar if you’d like. Cut into 12 bars and serve.
