Step‑by‑Step Instructions for Cinnamon Oatmeal Stuffed Apples
Step 1: Prepare Apples
Begin by preheating your oven to 350°F (175°C). Use a sharp knife or an apple corer to carefully core the large baking apples, ensuring to leave the bottom intact to hold the filling. Once cored, place the apples upright in a baking dish and set aside, ready for their sweet stuffing.
Step 2: Make Filling
In a large mixing bowl, combine the old-fashioned oats, brown sugar, granulated sugar, ground cinnamon, ground nutmeg, and salt. Melt the salted butter in a small microwave-safe bowl or on the stovetop, then pour it into the oat mixture. Stir until everything is thoroughly combined, ensuring the oats are well coated with the buttery goodness.
Step 3: Stuff Apples
Generously spoon the prepared oat filling into each cored apple, packing it down gently to maximize the filling. Don’t be shy—fill them up to the top! This delicious mixture will expand slightly during baking, creating a delightful contrast of textures in the Cinnamon Oatmeal Stuffed Apples.
Step 4: Bake
Carefully pour about an inch of water into the bottom of the baking dish to help steam the apples during cooking. Cover the dish tightly with aluminum foil to lock in moisture. Place the dish in your preheated oven and bake for approximately 50 minutes, or until the apples are tender and easily pierced with a fork but not mushy.
Step 5: Make Custard Sauce
While the apples are baking, prepare the Velvety Vanilla Custard Sauce. In a saucepan, combine milk, vanilla extract, sugar, and egg yolks, whisking until well blended. Cook over low heat, stirring constantly, until the mixture thickens, about 10-15 minutes. Remove from heat to let it cool slightly, thickening further as it cools.
Step 6: Serve
Once the Cinnamon Oatmeal Stuffed Apples are done baking, carefully remove them from the oven. Let them cool for a few moments before serving. Drizzle the luscious vanilla custard sauce over the warm stuffed apples to create a delightful presentation, and savor each comforting bite of this festive dessert.

Expert Tips for Cinnamon Oatmeal Stuffed Apples
-
Pick the Right Apples: Choose large baking apples like Honeycrisp or Granny Smith to ensure they hold up well during baking and provide a perfect sweet-tart balance.
-
Avoid Instant Oats: Stick with old-fashioned oats for a chewy texture in your filling—instant oats can make the mixture too mushy.
-
Don’t Overstuff: Fill the apples generously, but avoid overflowing, as the filling expands during baking, which can lead to a messy situation.
-
Test for Doneness: Gently pierce the apples with a fork towards the end of baking; they should be tender but not overly soft to ensure your Cinnamon Oatmeal Stuffed Apples hold their shape.
-
Custard Cooling: If making the Vanilla Custard Sauce ahead, let it cool to room temperature before refrigerating to prevent it from becoming grainy.
-
Taste Adjustments: Feel free to tweak the spices and sweetness level based on personal preference; cinnamon lovers might want to increase the amount for a warmer flavor!
How to Store and Freeze Cinnamon Oatmeal Stuffed Apples
Fridge: Store leftover Cinnamon Oatmeal Stuffed Apples in an airtight container for up to 3 days. This keeps them fresh while preserving their delightful flavors.
Freezer: For longer storage, freeze the stuffed apples before baking. Wrap them tightly in plastic wrap and then in aluminum foil. They can be kept in the freezer for up to 3 months.
Reheating: To reheat, bake the stuffed apples directly from frozen at 350°F (175°C) for about 60 minutes, or until heated through. Add more custard sauce if you like!

Cinnamon Oatmeal Stuffed Apples Recipe FAQs

Absolutely! I recommend using large baking apples like Honeycrisp or Granny Smith. They provide a lovely balance of sweetness and tartness while maintaining their structure during baking, which is essential for a perfect stuffed apple.
How should I store leftover Cinnamon Oatmeal Stuffed Apples?
You can store any leftovers in an airtight container in the fridge for up to 3 days. Just make sure they’re completely cool before sealing them up. This way, they’ll stay fresh and delicious, ready for a cozy treat!
Can I freeze Cinnamon Oatmeal Stuffed Apples?
Yes, you can! For freezing, I often wrap each stuffed apple tightly in plastic wrap and then in aluminum foil to prevent freezer burn. They can be stored in the freezer for up to 3 months. When you’re ready to enjoy, bake them from frozen at 350°F (175°C) for about 60 minutes or until heated through.
What if my custard sauce turns out grainy?
To avoid a grainy texture in your vanilla custard sauce, be sure to let it cool at room temperature before refrigerating. If it does become grainy, you can gently reheat it while whisking continuously until smooth. Alternatively, you could strain the sauce through a fine mesh sieve to remove any lumps.
Can I make adjustments for dietary restrictions?
Very! If you have dietary considerations, you can easily adjust the recipe. For a dairy-free option, substitute milk with a plant-based alternative like almond or oat milk, and use a dairy-free butter substitute. Additionally, if anyone has a nut allergy, just double-check your ingredients’ labels to ensure they’re nut-free.
What should I do if my apples are overflowing during baking?
If you notice that the filling is overflowing from the apples as they bake, it often helps to pack the filling a little less tightly next time. If it happens anyway, simply keep a baking sheet underneath the apples to catch any delicious drips and avoid a messy oven cleanup!
