Preheat your oven to 350°F.
Mix up your pancake batter according to the package instructions until it's nice and smooth.
Spray a baking sheet with oil and spread the batter on top.
Arrange your apple slices on top of the batter and sprinkle with cinnamon.
Bake in the oven for 20-22 minutes, or until it's cooked through.
Once it's cooled, cut it into squares, drizzle some maple syrup on top, and serve!
