How to Make Apple Cinnamon Oatmeal Bake
This Apple Cinnamon Oatmeal Bake is a dream come true for anyone seeking a delicious and incredibly satisfying breakfast without the fuss. In under an hour, you’ll have a warm, comforting dish with a delightful texture and comforting spice, perfect for fueling your day or enjoying a sweet treat. The preparation is simple, and the result is a golden-brown, slightly chewy oatmeal bake that’s infinitely better than anything from a box, boasting a perfect balance of sweet apple and warming cinnamon, with a wonderfully tender crumb.
Step-by-Step Instructions
Preheat Your Oven and Prepare the Baking Dish: Begin by preheating your oven to 375°F (190°C). This ensures your bake cooks evenly and achieves that desirable golden-brown crust. Grease an 8×8 inch baking dish generously with butter or cooking spray to prevent sticking. A well-greased dish is key to easily serving your delicious Apple Cinnamon Oatmeal Bake.
Combine Dry Ingredients: In a large mixing bowl, whisk together the rolled oats, all-purpose flour, packed light brown sugar, baking powder, ground cinnamon, ground nutmeg, and salt. This thorough mixing ensures that all the dry components are evenly distributed, leading to a uniform flavor and texture throughout the bake. Make sure there are no clumps of brown sugar.
Combine Wet Ingredients: In a separate medium bowl, whisk together the eggs until lightly beaten, then stir in the milk, melted unsalted butter, and vanilla extract. The melted butter adds richness and a tender texture, while the milk provides the necessary moisture for the oats and flour to absorb and soften. The vanilla extract enhances the overall flavor profile.
Combine Wet and Dry Mixtures: Pour the wet ingredients into the bowl with the dry ingredients. Stir gently with a spatula or wooden spoon until just combined. Be careful not to overmix; a few small lumps are perfectly fine and can even contribute to a better texture. Overmixing can develop the gluten in the flour, potentially making the bake tough.
Incorporate the Apple: Add the diced apple to the batter and stir gently to distribute it evenly throughout the mixture. The apple will soften as it bakes, releasing its natural sweetness and creating delightful pockets of fruit within the oatmeal bake. If you’re adding nuts, this is also a good time to stir them in for an extra crunch.
Pour into Baking Dish and Bake: Pour the batter evenly into the prepared baking dish. If you haven’t already, sprinkle any optional chopped pecans or walnuts over the top of the batter for added texture and flavor. Place the baking dish in the preheated oven.
Bake Until Golden and Set: Bake for 25-35 minutes, or until the edges are golden brown and the center is set. You can test for doneness by inserting a toothpick into the center; it should come out mostly clean with a few moist crumbs attached. The aroma of cinnamon and apples should fill your kitchen!
Cool Slightly Before Serving: Once baked, remove the Apple Cinnamon Oatmeal Bake from the oven and let it cool in the dish for at least 5-10 minutes before serving. This allows it to set up properly, making it easier to portion and serve.

Storing and Reheating Tips
You can store leftover Apple Cinnamon Oatmeal Bake in an airtight container in the refrigerator for up to 3-4 days. Ensure the bake has cooled completely before sealing the container to prevent condensation. This method keeps the bake fresh and prevents it from becoming soggy.
To reheat individual portions, place a slice on a plate and microwave for 30-60 seconds, or until warmed through. For a crispier texture, you can reheat slices in a toaster oven or a regular oven at 350°F (175°C) for about 5-10 minutes. If you wish to freeze portions for future meals, let the bake cool completely, then cut into individual servings and wrap each tightly in plastic wrap followed by a layer of aluminum foil or place them in freezer-safe containers. Frozen Apple Cinnamon Oatmeal Bake will keep well for up to 2-3 months and can be reheated directly from frozen using a similar method as above, possibly requiring a slightly longer reheating time.
