Oatmeal Apple Breakfast Bake Ingredients
For the Bake
- Old-fashioned oats – The key base for texture and volume; you can use steel-cut oats for a chewier consistency, but adjust cooking times!

- Large apple – Brings natural sweetness and fruitiness; Granny Smith or Honeycrisp apples add a nice balance of tart and sweet.
- Eggs – These bind the ingredients together for a firm structure; replace with flax eggs for a vegan version.
- Maple syrup or honey – Sweetens the dish naturally; feel free to adjust the quantity or try mashed banana as a substitute.
- Vanilla extract – Enhances flavors wonderfully; can be swapped for almond extract if you prefer a nutty note.
- Cinnamon – Infuses warmth and spice; you can also try nutmeg or cardamom for a distinctive twist.
- Baking powder – Essential for helping the bake rise, so make sure it’s fresh for optimal results.
- Salt – Balances the sweetness and elevates the overall flavor.
Optional Add-ins

Step‑by‑Step Instructions for Oatmeal Apple Breakfast Bake
Step 1: Prepare Oven and Dish
Preheat your oven to 375°F (190°C) while you prepare your baking dish. Grease a 9×13 inch baking dish with a bit of butter or non-stick spray to prevent sticking. This initial step ensures that your Oatmeal Apple Breakfast Bake will come out easily and beautifully golden.
Step 2: Combine Dry Ingredients
In a large mixing bowl, mix together 2 cups of old-fashioned oats, 1 teaspoon of cinnamon, 1 teaspoon of baking powder, and a pinch of salt. Stir thoroughly to ensure that all dry ingredients are evenly distributed. This blend forms the base of your Oatmeal Apple Breakfast Bake, which will provide great texture and flavor.
Step 3: Combine Wet Ingredients
In another bowl, whisk together 1 ½ cups of milk, 2 large eggs, 1/3 cup of maple syrup, and 1 teaspoon of vanilla extract until smooth and creamy. This liquid mixture adds moisture and sweetness to your bake. Make sure to blend well to create a cohesive texture that compliments the dry mix effortlessly.
Step 4: Assemble the Bake
Fold diced apples, about 2 cups, into the bowl of dry ingredients, ensuring they are well coated. Then, pour the wet mixture over the combined ingredients and gently stir until everything is mixed together. If desired, this is the perfect moment to add in chopped walnuts or pecans for an extra crunch.
Step 5: Bake
Transfer the mixture into your prepared baking dish, spreading it out evenly with a spatula. Place the dish in the preheated oven and bake for 40-50 minutes or until the top is golden brown and set. The bake should rise slightly and smell wonderfully aromatic, signaling deliciousness to come.
Step 6: Cool and Serve
Once baked, remove the dish from the oven and let it cool for 10-15 minutes before slicing. This resting time helps the Oatmeal Apple Breakfast Bake to firm up, making serving easier. You might like to drizzle with maple syrup or top with Greek yogurt for added creaminess when serving.
Step 7: Store/Freeze
If you have leftovers, they can be stored in the refrigerator for 4-5 days. Alternatively, you can freeze them for up to 3 months. To reheat, simply place in the microwave or oven until warmed through, for a cozy breakfast option ready whenever you need it!

Absolutely! For the Oatmeal Apple Breakfast Bake, I recommend using Granny Smith or Honeycrisp apples.

What can I do if my Oatmeal Apple Breakfast Bake isn’t setting properly?
Don’t worry! If your bake is not setting properly, it may need a little more time in the oven. I typically check for doneness around the 40-minute mark.

Make sure to keep the bake evenly spread in the dish and keep an eye on the top to avoid over-browning.

Absolutely! The Oatmeal Apple Breakfast Bake can easily be modified for nut allergies.
