- 1 cup oats (rolled) – Rolled oats provide a chewy texture and absorb the flavors beautifully.
- 1 teaspoon cinnamon – Adds warmth and spice, making each bite cozy and inviting.

For the Vanilla Custard Sauce
- 2 cups milk – Whole milk creates a rich custard, but feel free to use low-fat if preferred.
- 1/4 cup sugar – Sweetens the custard without overpowering its creamy goodness.
- 3 tablespoons cornstarch – Acts as a thickening agent for a smooth and velvety texture in the sauce.
- 1 teaspoon vanilla extract – Infuses the custard with aromatic sweetness that complements the apples perfectly.

Pro Tips for Cinnamon Oatmeal Stuffed Apples with Vanilla Custard Sauce
- Apple Selection: Choose firm apples like Honeycrisp or Granny Smith; they hold their shape better during baking and balance sweetness with tartness.

- Even Baking: Arrange stuffed apples evenly in the baking dish, allowing space between each to ensure they bake uniformly and get tender without steaming.
- Custard Thickness: Keep whisking the custard while cooking to prevent lumps; if it’s too thick, add a splash of milk to reach your desired consistency.
- Serving Temperature: Serve the Cinnamon Oatmeal Stuffed Apples with Vanilla Custard Sauce warm for the best flavor and texture; they taste even better fresh out of the oven!
