Step‑by‑Step Instructions for Oatmeal Apple Breakfast Bake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it heats, gather your ingredients and prepare an 8×8-inch baking dish by lightly greasing it with cooking spray or butter. This will ensure that your cozy Oatmeal Apple Breakfast Bake comes out easily and with a golden, lightly crisp top.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, combine the old-fashioned oats, baking powder, and cinnamon. Stir these dry ingredients together until they’re well mixed, allowing the spices to disperse evenly. This seasoning is crucial as it brings out the warm, inviting flavor of the oatmeal apple bake that will fill your kitchen with delightful aromas.
Step 3: Whisk the Wet Ingredients
In another bowl, whisk together the milk and maple syrup until smooth and fully combined. Then, add the diced apples and stir to coat them evenly. This mixture adds moisture and sweetness to the bake, ensuring every bite of your Oatmeal Apple Breakfast Bake is bursting with flavor from the tender apple pieces.
Step 4: Combine the Mixtures
Pour the wet mixture over the dry ingredients, gently folding to combine everything. Use a spatula to mix until just incorporated, being careful not to overmix; you want the oats to absorb the moisture while keeping a lovely texture. The mixture should be slightly thick and ready for the baking dish.
Step 5: Transfer to Baking Dish
Pour the combined batter into your prepared baking dish, spreading it evenly with the back of a spatula. Make sure the batter reaches all the corners and is level. This step is essential for ensuring even cooking throughout your Oatmeal Apple Breakfast Bake, leading to a delightful slice every time.
Step 6: Sprinkle Nuts on Top
For a crunchy texture, sprinkle the chopped walnuts evenly over the surface of the batter. These will add a lovely contrast to the soft, baked oats. If you prefer a nut-free version, feel free to skip this step. The Oatmeal Apple Breakfast Bake will still be delicious and comforting!
Step 7: Bake to Perfection
Place the baking dish in the preheated oven and bake for 35-40 minutes. Keep an eye on it; the top should be lightly browned, and the center should spring back when gently pressed. This is when you know your Oatmeal Apple Breakfast Bake is ready to come out, revealing a golden crust that beckons you to dig in.
Step 8: Cool Slightly Before Serving
Once baked, remove the dish from the oven and allow the Oatmeal Apple Breakfast Bake to cool slightly for about 10 minutes. This cooling time helps the bake to set further and makes slicing easier. Cut into squares and enjoy warm, perhaps with a drizzle of extra maple syrup for an indulgent touch!
How to Store and Freeze Oatmeal Apple Breakfast Bake
Fridge: Store your Oatmeal Apple Breakfast Bake in an airtight container for up to 3 days. Reheat individual portions in the microwave for a quick warm-up.

Reheating: To enjoy your frozen slices, simply thaw them overnight in the fridge and reheat in the microwave or oven until warmed through.
Cooling Tip: Allow the bake to cool completely before storing to prevent excess moisture from making it soggy while stored.
