- For the vanilla custard sauce:
- Milk: The creamy base for custard, making it silky smooth.
- Sugar: Sweetens the custard to a perfect balance.

How to Make Cinnamon Oatmeal Stuffed Apples with Vanilla Custard Sauce Recipe
Step 1: Prep and Prepare
First, preheat your oven to 350°F (175°C) and lightly grease a baking dish. This sets the stage for a smooth baking process and prevents sticking. Washing and coring the apples comes next — make sure to leave the base intact so the filling stays put when baked.
Step 2: Mix the Filling
In a mixing bowl, combine rolled oats, brown sugar, cinnamon, salt, and melted butter until everything comes together beautifully. If you’re feeling adventurous, toss in some chopped nuts or dried fruit like raisins or cranberries; these add bursts of texture and flavor that elevate the whole dish.
Step 3: Stuff the Apples
Generously fill each apple with your oatmeal mixture, pressing lightly so it’s snug but not packed too tight. Arrange the apples upright in your baking dish, making sure they’re stable and ready to soak up flavors.
Step 4: Bake to Perfection
Pour about one cup of water into the bottom of the baking dish — this helps steam the apples gently while baking. Cover with foil and pop them into the oven for about 25 to 30 minutes, or until the apples are tender but not mushy, and the filling is golden and inviting.
Step 5: Make the Vanilla Custard Sauce
While the apples bake, start the sauce by combining milk, sugar, cornstarch, and salt in a saucepan. Warm over medium heat, whisking constantly to avoid lumps, until the mixture simmers. In a separate bowl, whisk egg yolks and vanilla extract. Slowly whisk the warm milk mixture into the yolks to temper them, then return everything to the pan. Cook gently while stirring until the custard thickens to a luscious consistency. Remove from heat and allow to cool slightly.
Step 6: Serve It Up!
Once your apples have baked to tender perfection, serve them right away, generously drizzled with warm vanilla custard sauce. The marriage of warm spices, soft apples, and creamy custard is pure magic!
How to Serve Cinnamon Oatmeal Stuffed Apples with Vanilla Custard Sauce Recipe

Garnishes
Sprinkle a little extra cinnamon or a dusting of powdered sugar right before serving for added visual appeal. A few fresh mint leaves or a handful of chopped toasted nuts can also give a refreshing contrast both in taste and texture.
Side Dishes
This dish pairs beautifully with light breakfast items like crispy bacon or sausage for a hearty brunch, or you can enjoy it solo as a comforting dessert. A hot cup of spiced tea or coffee completes the experience wonderfully, balancing the sweetness of the apples and custard.
Creative Ways to Present
For a stunning presentation, serve each stuffed apple on a shallow bowl or plate and swirl vanilla custard sauce around them to create a delicate “canvas.” Alternatively, add a scoop of vanilla ice cream alongside for a decadent twist that’s sure to wow your guests.
Make Ahead and Storage
Storing Leftovers
If you have any leftover Cinnamon Oatmeal Stuffed Apples with Vanilla Custard Sauce Recipe, store the apples and custard separately in airtight containers in the refrigerator. The apples stay tender and flavorful for up to 3 days, while the custard remains silky and fresh.
Freezing
Freezing isn’t highly recommended for the custard sauce because of potential texture changes. However, you can freeze the baked stuffed apples without the sauce for up to 2 months. Thaw overnight in the fridge and warm gently before serving.
Reheating
To reheat, place the stuffed apples in a preheated oven at 300°F (150°C) for about 10-15 minutes until warmed through. Heat the custard sauce gently in a saucepan over low heat, stirring constantly to bring back its creamy, smooth texture without curdling.
FAQs
Can I use different types of apples for this recipe?
Absolutely! While Honeycrisp and Granny Smith are ideal for their balance of sweetness and tartness, you can experiment with other firm apples like Fuji or Gala. Just ensure they hold their shape after baking to avoid mushy results.
Is there a way to make the custard sauce dairy-free?
Yes, you can substitute regular milk for almond, oat, or coconut milk. Keep in mind that the flavor and consistency might differ slightly, so adjust the sweetness and thickening carefully.
Can I prepare the oatmeal stuffing in advance?
Definitely! You can mix the oatmeal stuffing and store it in the fridge for up to 24 hours. Just give it a quick stir before filling the apples to refresh the flavors.
What can I use instead of dried fruit or nuts?
If you’re allergic or not a fan, consider adding a splash of maple syrup or a handful of fresh berries into the oatmeal mixture for a fruity twist without the dryness.
How thick should the custard sauce be?
The custard should be thick enough to coat the back of a spoon but still pourable. If it gets too thick after cooling, whisk in a little warm milk to loosen it up before serving.
