Method
Preheat and prep the pan
- Preheat oven to 350F and grease a 9x13 baking pan so the batter releases cleanly.
- Prepare your oven-safe workspace with the pan ready before mixing to keep the batter from waiting.
Mix the dry ingredients
- Whisk all-purpose flour, baking powder, cinnamon, nutmeg, allspice, and salt until evenly combined and no spice pockets remain.
Mix the wet ingredients
- Whisk melted unsalted butter and both sugars until smooth and glossy, then whisk in eggs and vanilla extract until fully incorporated.
Combine and bake
- Fold the flour mixture into the wet mixture just until combined to keep the crumb tender.
- Fold in diced apples and walnuts or pecans (if using) so the fruit is distributed throughout the batter.
- Spread the batter evenly in the prepared pan for even baking.
- Bake at 350F for 30-35 minutes until a toothpick comes out with just a few moist crumbs and the top looks set and golden-brown.
Cool and finish
- Cool in the pan until the bars are firm enough to slice, then drizzle with caramel sauce before cutting into squares.
Notes
For clean, fudgy slices, cool the brownies in the pan until firm (then slice). Store airtight at room temperature up to 2 days or refrigerate up to 5 days; freeze up to 2 months. For a lower-sugar swap, replace half the granulated sugar with an equal amount of brown sugar alternative made for baking (measure by weight if your brand provides it).
