👨🍳 Instructions
Preheat your oven to 375°F (190°C) and lightly grease an 8x8 inch baking dish.
In a medium bowl, whisk together the rolled oats, baking powder, and ground cinnamon.
In a separate bowl, whisk together the milk, egg, melted butter, and maple syrup, then stir in the diced apples or blueberries.
Pour the wet fruit and milk mixture into the dry oat mixture and stir thoroughly until well combined.
Transfer the mixture into the prepared baking dish, pressing it down evenly.
Bake for 25 minutes until the center is set and the edges are lightly golden. Let cool completely before slicing into neat squares.
⚠️ Common Mistakes
- ✕
Cutting the squares while they are still piping hot, which causes them to crumble apart.
- ✕
Skipping the baking powder, resulting in a dense and flat texture instead of a cake-like bar.
🔄 Variations
Swap diced apples for mashed ripe banana or raspberries depending on seasonal fruit availability.
Stir in 2 tablespoons of chia seeds or flaxseed meal for an extra boost of fiber and omega-3s.
🧊 Storage
- 📦
Store leftover squares in an airtight container in the refrigerator for up to 4 days, or freeze individually for quick weekday morning microwave reheating.
💡 Chef Tips
Cut the squares into bite-sized pieces so younger children can easily self-feed without making a mess.
Use certified gluten-free oats if managing a gluten sensitivity in the household.
❓ FAQ
Can I make these ahead of time? Yes, these squares are designed for meal prep and can be baked over the weekend for the entire school week.
Are these very sweet? No, they rely on natural fruit sweetness and a touch of maple syrup to keep added sugars low and balanced for young children.
