Ingredients
Main Ingredients
- 0.875 cup unsalted butter, melted
- 2.25 cup all-purpose flour
- 1.25 cup old-fashioned rolled oats
- 0.75 cup light brown sugar, packed
- 0.5 cup granulated sugar divided
- 1 tsp baking powder
- 0.5 tsp fine sea salt
- 2 tsp ground cinnamon divided
- 1.5 tsp pure vanilla extract
- 4 cup peeled apples, diced
- 1 tbsp fresh lemon juice
- 1.5 tbsp cornstarch
- 0.25 tsp ground nutmeg
- 1 cup chopped walnuts toast for extra crunch
Instructions
Preparation Steps
- Preheat oven to 350°F. Line a 9×13-inch pan with parchment, leaving overhang.
- Whisk flour, oats, brown sugar, half the granulated sugar, baking powder, salt, and 1½ tsp cinnamon in a bowl.
- Pour in melted butter and vanilla. Stir until the mixture forms moist, sandy clumps.
- Press about two-thirds of the mixture firmly into the prepared pan to form the crust. Reserve the rest for topping.
- Toss diced apples with lemon juice, remaining granulated sugar, remaining ½ tsp cinnamon, nutmeg, and cornstarch.
- Spread the apple mixture evenly over the crust.
- Fold chopped walnuts into the reserved crumb and sprinkle evenly over the apples.
- Bake 38–45 minutes, until the topping is deep golden and the filling is bubbling at the edges.
- Cool completely in the pan. Chill 1 hour for cleaner slices, then lift out and cut into bars.
Notes
Try swapping the walnuts with pecans, or drizzle the cooled bars with warm caramel. Store covered at room temperature for 2 days or refrigerate up to 5 days; freeze up to 2 months, well wrapped.
