Creating the 3 Ingredient Apple Cake is a breeze if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish.
2. Prepare Apples: Peel, core, and dice the apples into small pieces. Set aside.
3. Mix the Ingredients: In a large mixing bowl, combine the diced apples, flour, and sugar. Stir until everything is evenly coated.
4. Transfer to Baking Dish: Pour the mixture into the greased baking dish, spreading it evenly.
5. Bake: Place the baking dish in the preheated oven and bake for 45-50 minutes or until the cake is golden brown.
6. Check for Doneness: Insert a toothpick into the center; it should come out clean when the cake is ready.
7. Cool the Cake: Allow the cake to cool in the baking dish for 5-10 minutes before slicing.
