Ingredients
Method
- Preheat oven to 350°F (175°C).
- Line a 9×13-inch metal baking pan with parchment and lightly grease.
- Melt butter and semisweet chocolate together until smooth.
- Cool for several minutes.
- Whisk in granulated and brown sugars.
- Add four eggs one at a time.
- Stir in vanilla.
- Whisk flour, cocoa powder, and salt separately.
- Fold dry ingredients into the chocolate mixture just until combined.
- Spread batter evenly in the prepared pan.
- Partially bake for 18–20 minutes.
- Meanwhile, roughly chop the pecans.
- Whisk melted butter, brown sugar, maple syrup, two eggs, bourbon, vanilla, and salt.
- Fold in pecans.
- Remove the partially baked brownie layer from the oven.
- Gently spoon the pecan mixture over the surface.
- Return to the oven and bake another 25–30 minutes.
- Remove when the topping is set around the edges with a slight movement toward the center.
- Cool completely on a wire rack.
- Chill for approximately 1 hour for cleaner slices if desired.
- Lift from the pan using parchment.
- Cut into approximately 24 squares.
Notes
Partially baking the brownie base helps keep the brownie and pecan layers distinct. Use pure maple syrup rather than pancake syrup. For a bourbon-free version, replace the bourbon with 2 tablespoons additional maple syrup. Don't overbake—the brownie base should remain fudgy. Cool completely before slicing because the pecan layer firms substantially as it cools.
