Step‑by‑Step Instructions for Baked Apple Oatmeal
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, take a moment to grease a 13x9-inch baking dish with softened butter; this will ensure your Baked Apple Oatmeal releases easily after baking. Set the prepared dish aside as you gather and mix the dry ingredients.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, combine the rolled oats, baking powder, ground cinnamon, kosher salt, and nutmeg. Stir the mixture until evenly blended, which will distribute the flavors throughout the Baked Apple Oatmeal. As you mix, the familiar scent of cinnamon will begin to fill your kitchen, adding to the cozy atmosphere.
Step 3: Whisk the Wet Ingredients
In another bowl, vigorously whisk together the eggs, whole milk, honey, vanilla extract, and melted butter until smooth. This creamy mixture will bring richness to your oatmeal. Be sure to blend these ingredients thoroughly, as they will help create that delightful custard-like texture in the finished dish.
Step 4: Combine Wet and Dry Ingredients
Gently pour the wet mixture into the bowl with the dry ingredients. Using a spatula, stir until just combined; avoid overmixing to keep your Baked Apple Oatmeal light and fluffy. The ingredients should be thoroughly moistened but still have some texture when combined for the best results.
Step 5: Add Apples and Walnuts
Fold in the chopped apples and walnuts, ensuring they're evenly distributed throughout the oatmeal mixture. The apples will provide natural sweetness and moisture, while the walnuts add a satisfying crunch. Take a moment to enjoy the aroma of fresh apples and spices as you prepare for baking.
Step 6: Pour Into Baking Dish
Carefully pour your mixture into the greased baking dish, spreading it out evenly. For an extra touch, sprinkle some additional cinnamon on top; this will enhance the visual appeal and aroma as it bakes. The anticipation builds as your dish is ready to go into the oven!
Step 7: Bake the Oatmeal
Place the baking dish in the preheated oven and bake for 40-45 minutes. You’ll know the Baked Apple Oatmeal is done when the top turns golden brown, and the edges are set. A toothpick inserted in the center should come out mostly clean, with just a hint of moistness indicating the perfect level of doneness.
Step 8: Cool and Serve
Once out of the oven, let the Baked Apple Oatmeal cool for about 20 minutes before slicing into squares. This cooling period helps the oatmeal firm up for clean slices. Serve warm, perhaps topped with your favorite yogurt or a drizzle of honey for a comforting finish.

Make Ahead Options
These Baked Apple Oatmeal squares are ideal for meal prep, saving you precious time on busy mornings! You can prepare the entire dish up to 24 hours in advance. Simply mix all your ingredients, pour the mixture into the greased baking dish, cover, and refrigerate until you are ready to bake. For best results, let it sit at room temperature for about 30 minutes before popping it in the oven, ensuring even cooking. Alternatively, you can bake it and refrigerate the leftovers for up to 4 days. Just reheat individual portions in the microwave or oven, and enjoy a delicious, warm breakfast, just as delightful as freshly made!

What if my Baked Apple Oatmeal turns out dense?
If your Baked Apple Oatmeal ends up dense, it might be due to overmixing. To achieve a light texture, try mixing the wet and dry ingredients just until combined. An extra tip: also ensure that your baking powder is fresh—expired leavening agents can lead to denser baked goods!
