Step‑by‑Step Instructions for Oatmeal Apple Breakfast Bake
Step 1: Preheat Your Oven
Begin your warm kitchen journey by preheating your oven to 350°F (175°C). This step is crucial as it prepares the environment for baking, ensuring your Oatmeal Apple Breakfast Bake rises beautifully and develops a golden crust. While the oven heats, gather your ingredients to keep everything within reach.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine old-fashioned oats, baking powder, ground cinnamon, and a pinch of salt. Use a whisk to ensure even distribution of all dry ingredients, which will create a harmonious base for your bake. The inviting aroma of cinnamon should start to fill the air, making your kitchen feel cozy.
Step 3: Combine Wet Ingredients
In a separate bowl, whisk together the eggs, milk, maple syrup, and a splash of vanilla extract until well blended. This mixture brings moisture to your Oatmeal Apple Breakfast Bake and binds the dry ingredients. Watch for a creamy consistency that ensures all the flavors meld together perfectly.
Step 4: Combine Mixtures
Gradually pour the wet mixture into the dry ingredients, stirring gently until just combined. Be careful not to overmix, as this can lead to a denser texture. Fold in the chopped apples and walnuts, ensuring they are evenly distributed throughout the batter, adding pops of sweetness and crunch to each bite.
Step 5: Prepare for Baking
Grease a baking dish lightly with non-stick spray or butter to prevent sticking. Pour the oatmeal mixture into the prepared dish, spreading it evenly with a spatula to create a smooth top. This preparation allows your bake to rise evenly as it cooks, promising a delightful texture once baked.
Step 6: Bake to Perfection
Place the baking dish in your preheated oven and bake for 35-40 minutes. Look for a golden-brown top and a set center; a toothpick inserted should come out clean. This visual cue indicates the Oatmeal Apple Breakfast Bake is ready to embrace your morning routine.
Step 7: Cool and Serve
Once baked, remove your delectable creation from the oven and allow it to cool for about 10 minutes. This cooling period helps set the bake for easier slicing. Serve warm, topped with a dollop of yogurt or a drizzle of maple syrup for a heartwarming start to your day!

Storage Tips for Oatmeal Apple Breakfast Bake
Fridge: Store leftovers in an airtight container in the fridge for up to 3 days to maintain freshness and flavor.

Reheating: To enjoy your Oatmeal Apple Breakfast Bake again, simply reheat in the microwave for a minute or warm slices in the oven at 350°F (175°C) for about 10-15 minutes.
Serving Ideas: Pair with a dollop of Greek yogurt or a drizzle of maple syrup when serving again for an added touch of comfort.
