Preheat your oven to 350°F. Grease and flour a 9-inch round cake pan to prevent sticking.
In a large mixing bowl, combine the cake mix, eggs, and vegetable oil. Use an electric mixer to blend the ingredients together until smooth and well combined.
Gently fold in the apple pie filling into the cake batter. Be careful not to overmix to maintain the texture of the apples.
Pour the prepared batter into the greased cake pan, spreading it evenly. Sprinkle with optional cinnamon or walnuts for added flavor.
Place the cake in the oven and bake for 45-50 minutes, or until a toothpick inserted into the center comes out clean and the top is golden brown.
Allow the cake to cool in the pan for about 10 minutes. Then transfer it to a wire rack to cool completely before serving.
Serving
Serve the cake warm with a scoop of vanilla ice cream or a drizzle of caramel sauce for an indulgent dessert experience.
