Let’s be honest: mornings can be a whirlwind. One moment you’re hitting snooze for the third time, the next you’re frantically searching for your keys, trying to remember if you’ve even had a sip of water, let alone a nourishing meal. Too often, "breakfast" becomes an afterthought.

Enter these Baked Oatmeal Squares - imagine: a warm, gently spiced baked square. These aren't just any oatmeal squares; they’re a little gift to your future self, making your week feel a bit calmer and much more nourished.

Why You’ll Fall in Love with These Baked Oatmeal Squares:

Effortless Meal Prep: Dedicate 15 minutes on a Sunday, and you’ll have grab-and-go breakfasts for the week! No more "what’s for breakfast?" panic!
Infinitely Adaptable: This recipe is a fantastic canvas for whatever you have on hand or whatever your taste buds desire.

Chef's Tips for Customization:

Make it Your Own: Feel free to swap out the berries for other fruits like diced apple, peaches, or even shredded zucchini for a hidden veggie boost!
Dairy-Free Option: Simply use your favorite plant-based milk and opt for mashed banana or applesauce instead of yogurt.
Sweetness Control: Adjust the maple syrup to your preference. If your fruit is very sweet, you might need less!
Let Them Set! Ensure your oatmeal squares are firm in the center before removing them from the oven. Letting them cool completely (or even chilling them) will make for perfectly clean cuts.

Baked Oatmeal Squares

Yields: 9-12 squares Prep time: 10 minutes Bake time: 35-45 minutes

Ingredients:

2 cups rolled oats (not instant)
1½ tsp baking powder
½ tsp salt
1 tbsp pumpkin pie spice
2 tsp ground cinnamon
2 cups coconut milk (but could use any dairy or plant-based)
2 large eggs, whisked
3 tbsp chia seeds
1/2 cup maple syrup
3–4 tbsp avocado oil
1 tbsp vanilla extract
1 cup fresh or frozen berries
¼ cup chopped nuts (walnuts, pecans, or almonds) for topping (optional)

For Garnish (Optional, but highly recommended!):

Greek yogurt
Fresh berries
A drizzle of honey or maple syrup

Instructions:

Preheat & Prep: Preheat your oven to 375°F (190°C). Lightly grease and flour (or line with parchment paper) a 9x13 inch baking dish.
Combine Dry Ingredients: In a large bowl, whisk together the rolled oats, baking powder, chia seeds, nuts, salt, spices.
Combine Wet Ingredients: In a separate medium bowl, whisk together the milk, egg, maple syrup, avocado oil, vanilla extract, until well combined.
Mix Together: Pour the wet ingredients into the dry ingredients and stir until just combined.
Pour & Top: Pour the mixture evenly into your prepared baking dish. Sprinkle the berries evenly over the top. Let set for 5-10 minutes. This allows the chia seeds to "bloom" and the oats to soak up some of the liquid, creating a moister square.
Bake: Bake for 35-45 minutes, or until the top is golden brown and the center is set and firm to the touch. A toothpick inserted into the center should come out mostly clean.
Cool & Cut: Let the baked oatmeal cool in the dish for at least 15-20 minutes before cutting into squares. For best results and cleanest cuts, allow it to cool completely before portioning.
Serve & Store: Serve warm or at room temperature. Garnish with a dollop of Greek yogurt, extra berries, and a drizzle of honey if desired. Store leftover squares in an airtight container in the refrigerator for up to 4-5 days.
