Recipe Instructions
Step 1
Preheat the oven to 350 degrees F (175 degrees C). Line a 9x9-inch square baking pan with enough parchment paper for overhang on all sides.
Step 2
Melt ½ cup butter in a medium saucepan over medium heat; simmer, stirring frequently, until butter is browned, fragrant, and foamy, with brown bits in it, 5 to 10 minutes. Pour into a large mixing bowl.
Step 3
Combine apples, 2 tablespoons brown sugar, 2 tablespoons butter, lemon juice, ¼ teaspoon cinnamon, and 1 pinch salt in the same saucepan over medium-low heat. Cook, stirring occasionally, until apples are softened, about 10 minutes.
Step 4
Mix water and cornstarch together in a small bowl: stir into the saucepan until combined. Cook until mixture thickens slightly, 1 to 2 minutes more. Cool slightly.
Step 5
Mix in remaining 1 teaspoon cinnamon, oats, flour, ½ cup brown sugar, vanilla, baking soda, nutmeg, and ¼ teaspoon salt to the brown butter mixture until well combined. Reserve 1 cup of oat mixture for topping.
Step 6
Pour remaining oat mixture into the prepared pan; firmly press into an even layer. Pour apples and sauce over top in an even layer: sprinkle with reserved oat mixture.
Step 7
Bake in the preheated oven until top is golden brown and crisp, 30 to 35 minutes. Cool completely, about 30 minutes. Cut into 16 bars.
