Preheat Your Oven: Set your oven to 375°F (190°C). This ensures it’s fully heated and ready by the time your oatmeal bake is prepared.
Prepare the Dry Ingredients: In a large mixing bowl, combine the rolled oats, baking powder, cinnamon, and salt. Stir the mixture until all the dry ingredients are evenly distributed. This step ensures that the flavors of the spices are incorporated throughout the bake.
Mix the Wet Ingredients: In a separate bowl, whisk together the milk, eggs, and 1/2 cup of caramel sauce. Make sure the caramel is fully blended into the liquid for even sweetness in every bite.
Combine Wet and Dry Ingredients: Pour the wet mixture into the bowl with the dry ingredients. Stir until everything is well combined. The oats will start absorbing the liquid, creating a thick, cohesive batter.
Fold in the Apples: Gently fold in the chopped apples. Distribute them evenly throughout the mixture so every serving has a generous amount of apple pieces.
Transfer to Baking Dish: Grease a 9×13 inch baking dish to prevent sticking. Pour the oatmeal mixture into the dish, spreading it out evenly with a spatula. This ensures even cooking and a consistent texture.
Add the Topping: Sprinkle the brown sugar evenly over the top of the bake. As it cooks, the sugar will melt and caramelize, forming a sweet and slightly crunchy topping.
Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes. The bake is ready when the top is golden brown, and the oatmeal is set but still moist.
Drizzle with Caramel: Once out of the oven, let the bake cool slightly. Then, drizzle the top generously with additional caramel sauce for an extra indulgent touch.
