Method
Prep
- Preheat the oven to 350F and grease a 9x13 baking pan so the brownies release cleanly.
Mix the dry and wet bases
- Whisk all-purpose flour, baking powder, cinnamon, nutmeg, and salt together until the spices are evenly distributed.
- Whisk melted unsalted butter and granulated sugar with brown sugar until smooth, then mix in eggs and vanilla extract until fully combined.
Fold, bake, and finish
- Fold the flour mixture into the wet mixture until just combined, keeping the batter thick with no dry streaks.
- Fold in diced apples and walnuts or pecans if using so the fruit pieces are evenly scattered.
- Spread the batter in the greased pan and bake for 30-35 minutes at 350F, until a toothpick comes out with just a few moist crumbs.
- Cool the brownies in the pan, then drizzle caramel sauce over the top before cutting into squares.
Notes
Pro tip: squeeze diced apples briefly in a clean towel if they look very wet, so the bars bake up dense instead of watery. Store covered at room temperature for up to 2 days or refrigerate for up to 5 days; freeze for up to 2 months (wrap portions well). For a lighter twist, use half brown sugar and half granulated sugar if you prefer a slightly less sweet bar.
