Method
Prep and preheat
- Preheat oven to 350F, then grease a 9x13 baking pan.
- Whisk all-purpose flour, baking powder, cinnamon, nutmeg, allspice, and salt in a bowl.
Make the batter
- Whisk melted unsalted butter and granulated sugar with brown sugar until smooth.
- Add eggs and vanilla extract, then mix until the batter is smooth.
- Fold in the flour mixture until just combined.
- Fold in diced apples and walnuts or pecans if using.
Bake and finish
- Spread the batter into the prepared pan evenly.
- Bake for 30-35 minutes, until a toothpick comes out with just a few moist crumbs.
- Cool in the pan, then drizzle with caramel sauce before cutting into squares.
Notes
Pro tip: chop apples very finely so they bake into the crumb rather than leaving larger chunks. Store covered at room temperature up to 2 days or in the fridge up to 5 days; freeze bars (wrapped tightly) up to 2 months. For a gluten-free option, use a 1:1 gluten-free all-purpose flour blend in place of the all-purpose flour.
