Method
Prep
- Preheat the oven to 350F and grease a 9x13 baking pan so the batter releases cleanly.
Mix dry and wet
- Whisk the all-purpose flour, baking powder, cinnamon, nutmeg, allspice, and salt until evenly combined.
- Whisk the melted unsalted butter and both sugars, then mix in the eggs and vanilla until smooth.
Combine and bake
- Fold the flour mixture into the wet mixture until just combined to keep the bars dense.
- Fold in the diced apples and walnuts or pecans if using, distributing the cinnamon-apple pieces throughout the batter.
- 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
- Cool the brownies in the pan, then drizzle with caramel sauce before cutting into squares.
Notes
Pro tip: dice the apples very finely so they bake into tender pockets without making the center gummy. Store covered in the fridge up to 4 days; freeze baked bars up to 2 months. For a gluten-aware swap, use a 1:1 gluten-free all-purpose flour blend in the same amount, and keep an eye on doneness at the low end of the bake time.
