Method
Bake the bars
- Preheat the oven to 350F and grease a 9x13 baking pan.
- Whisk together the all-purpose flour, baking powder, cinnamon, nutmeg, allspice, and salt.
- Whisk the melted unsalted butter and both sugars until smooth, then whisk in the eggs and vanilla extract.
- Fold the flour mixture in just until combined, then fold in the diced apples and chopped walnuts or pecans if using.
- Spread the batter in the prepared pan, then bake for 30-35 minutes until a toothpick comes out with just a few moist crumbs.
Finish and serve
- Cool the brownies in the pan before cutting into squares.
- Drizzle with caramel sauce before serving.
Notes
For clean slices, cool completely in the pan so the crumb sets before cutting. Store covered at room temperature up to 2 days or refrigerate up to 5 days; freeze up to 2 months. For a lighter option, swap half the granulated sugar with an equal amount of light brown sugar or use a reduced-sugar caramel for the drizzle.
