Ingredients
Equipment
Method
Preheat and prep pan
- Preheat the oven to 350F and grease a 9x13 baking pan so the batter releases easily after baking.
Mix dry ingredients
- Whisk together the all-purpose flour, baking powder, cinnamon, nutmeg, allspice, and salt until evenly combined.
Mix wet ingredients
- Whisk the melted unsalted butter with granulated sugar and packed brown sugar until smooth, then whisk in the eggs and vanilla extract until the mixture is cohesive.
Combine and add apples
- Fold the flour mixture into the wet mixture until just combined, stopping as soon as no dry streaks remain.
- Fold in the diced apples and walnuts or pecans if using, distributing them through the batter.
Bake
- Spread the batter evenly in the prepared 9x13 pan and bake for 30-35 minutes at 350F until a toothpick comes out with just a few moist crumbs.
Cool and finish
- Cool the brownies in the pan, then drizzle with caramel sauce before cutting into 16 squares.
Notes
Pro tip: dice the apples very small so they bake through and stay tender without making the bars gummy. Store covered at room temperature up to 2 days or in the refrigerator up to 5 days; freeze bars (well wrapped) for up to 2 months. For a gluten-free swap, use a 1:1 gluten-free all-purpose flour blend to keep the crumb similar.
