1-First Step: Gather and Mix the Filling Start by preheating the oven to 375°F (191°C) so it’s ready when you are. In a bowl, mix the softened butter, brown sugar, cinnamon, and nutmeg until they’re well combined this creates the sweet, spicy base. Then, stir in the oats and any optional add-ins like raisins or nuts for added texture.

2-Second Step: Prepare the Apples Core the 4 large apples to create a well in the center for the filling, being careful not to cut all the way through. Place the apples in an 8-inch or 9-inch baking pan, standing them upright so they hold their shape during baking.

3-Third Step: Add the Filling and Liquid Spoon the prepared filling into each cored apple, packing it in gently. Pour the 3/4 cup of warm water into the bottom of the pan to help steam the apples as they bake.

4-Fourth Step: Bake the Apples Slide the pan into the preheated oven and bake for 40-45 minutes, or until the apples are tender when pierced with a fork. Keep an eye on them to avoid overcooking, as this ensures the best apples for baking maintain their shape.

5-Final Step: Serve and Enjoy Remove the apples from the oven and let them cool slightly. Serve them warm, basting with the pan juices for extra flavor, and add toppings like whipped cream or ice cream if desired. This step makes your baked apples with cinnamon even more delightful for cozy evenings.
