How to Make Baked Oat Cinnamon Apple Bars Recipe
For the Apple Oat Base:
- Preheat your oven to 350°F and line an 8×8-inch pan with parchment paper for easy removal. This step ensures even baking and perfect golden edges.
- Mix rolled oats, all-purpose flour, brown sugar, cinnamon, baking powder, and salt in a large bowl until evenly combined, forming the hearty base of these delicious bars.
- Press two-thirds of the oat mixture firmly into the prepared pan, creating a compact base layer that bakes into a sturdy, tender crust.
For the Apple Filling:
- Toss diced apples with lemon juice, maple syrup, and ground nutmeg in a medium bowl, ensuring every piece is coated in sweet, spiced flavor.
- Layer the apple mixture evenly over the oat base, using a spatula to spread it into a neat, tart-sweet filling layer.
For the Topping & Assembly:
- Crumble the remaining oat mixture and cold, cubed butter over the apples, creating a buttery, crumbly topping that bakes to golden perfection.
- Bake the bars at 350°F for 25–30 minutes, until the topping is golden brown and the apples bubble at the edges.
- Cool the bars in the pan on a wire rack for at least 15 minutes, allowing slices to set for clean, beautiful squares.
Optional: Serve warm with a dollop of vanilla yogurt or a drizzle of maple syrup.
