Step‑by‑Step Instructions for Oatmeal Apple Breakfast Bake
Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). This crucial step ensures that your Oatmeal Apple Breakfast Bake cooks evenly and achieves that perfect golden top. As the oven warms up, gather your mixing bowl and measuring cups for the next steps, setting up a cozy kitchen environment filled with anticipation.
Step 2: Mix the Base Ingredients
In a large mixing bowl, combine old-fashioned oats, milk, maple syrup, and a generous sprinkle of cinnamon. Stir the mixture well until everything is thoroughly combined and you see a creamy texture forming. This step is where the base for your Oatmeal Apple Breakfast Bake comes together, so ensure no dry oats are left uncoated.
Step 3: Add the Apples and Walnuts
Once your mixture is unified, gently fold in the chopped apples and walnuts. Use a spatula to ensure all pieces are evenly distributed throughout the mixture, creating a delightful blend of flavors and textures. The sweet smell of apples should start to emerge, adding to the excitement of making this hearty breakfast.
Step 4: Prepare the Baking Dish
Grease an 8×8-inch baking dish with a bit of butter or cooking spray to prevent sticking. Carefully pour the oatmeal mixture into the dish, spreading it evenly. Make sure the surface is level to ensure even baking. The anticipation of your Oatmeal Apple Breakfast Bake rising in the oven will fill the air with warmth.
Step 5: Bake to Perfection
Place your baking dish in the preheated oven and bake for 35-40 minutes. Keep an eye on it, as the top should turn golden brown, and a toothpick inserted in the center should come out clean. This step enhances the flavors and creates that perfect chewy texture, making your Oatmeal Apple Breakfast Bake truly irresistible.
Step 6: Cool and Serve
Once fully baked, remove the dish from the oven and let it cool for about 10 minutes. This cooling time allows the bake to set slightly for easier slicing. Afterward, cut into squares and serve warm. Enjoy your hearty Oatmeal Apple Breakfast Bake by itself or complement it with yogurt or a drizzle of almond butter for an extra treat.

Make Ahead Options
These Oatmeal Apple Breakfast Bake dishes are perfect for busy mornings, allowing you to enjoy a wholesome meal with minimal effort! You can prepare the mixture (oats, milk, maple syrup, and cinnamon) up to 24 hours in advance by combining everything in a bowl and covering it tightly before refrigerating. Chop the apples and walnuts a few hours before baking to ensure they stay fresh—just toss them in lemon juice to prevent browning. When ready to serve, simply pour the mixture into a greased baking dish, fold in the apples and walnuts, and bake as instructed. This way, you’ll have a delicious breakfast that’s just as comforting and satisfying, ready to fuel your day!
