- 1 tablespoon fresh lemon juice
- 1 ½ tablespoons cornstarch
For the Buttery Pecan Streusel Topping:
- ½ cup all-purpose flour
- ¼ cup packed light brown sugar
- 2 tablespoons granulated sugar
- ½ teaspoon ground cinnamon
- ¼ cup cold unsalted butter cut into small pieces
- ½ cup chopped pecans
Instructions
Preparation
- Preheat oven to 350°F (175°C) and line a 9x13 inch baking pan with parchment paper, ensuring an overhang for easy removal.
- In a large bowl, whisk melted butter and granulated sugar, then whisk in eggs one at a time, followed by vanilla extract.
- In a separate bowl, whisk together flour, cocoa powder, and salt; gradually add to the wet ingredients until just combined, then fold in chocolate chips.
- Spread about two-thirds of the prepared brownie batter evenly into the lined baking dish.
- Combine diced apples, brown sugar, cinnamon, nutmeg, lemon juice, and cornstarch in a medium bowl, tossing gently to coat the apples.
- For the streusel, combine flour, brown sugar, granulated sugar, and cinnamon in another medium bowl; cut in cold butter until coarse crumbs form, then stir in chopped pecans.
- Spoon the apple filling over the brownie batter, dollop the remaining brownie batter on top, gently spreading, then drizzle and swirl warmed caramel sauce.
- Generously sprinkle the pecan streusel topping over the entire surface of the bars.
- Bake for 45-55 minutes until the edges are set, the streusel is golden, and a toothpick inserted into the brownie comes out with moist crumbs.
Cooling
- Allow the bars to cool completely in the pan on a wire rack before lifting and slicing into squares.
Notes
Do not overmix the brownie batter to ensure a fudgy texture. Allow the bars to cool completely before slicing for clean cuts and to prevent crumbling.
