Method
Brown butter and prep the pan
- Brown the butter until golden and nutty, then cool for 10 minutes.
- Preheat the oven to 350F, then grease a 9x13 pan.
Mix the dry ingredients
- Whisk the all-purpose flour, baking powder, cinnamon, cream of tartar, nutmeg, and salt until evenly combined.
Mix the wet ingredients
- Whisk the browned butter and packed brown sugar until smooth.
- Whisk in the eggs and vanilla extract until smooth.
Combine and top
- Fold the flour mixture into the wet ingredients until just combined.
- Fold in the finely diced apples.
- Spread the batter into the prepared 9x13 pan.
- Mix the sugar and cinnamon for the top, then sprinkle generously over the surface.
Bake and finish
- Bake for 25-30 minutes at 350F, until a toothpick comes out with just a few crumbs.
- Drizzle with caramel and cool completely before slicing.
Notes
Pro tip: cool the browned butter for the full 10 minutes to keep the eggs from scrambling and to help the blondies bake up with a dense, chewy texture. Store airtight in the refrigerator up to 4 days; freeze baked bars up to 2 months. For a lighter option, you can swap half the brown sugar for a 1:1 baking sweetener (use package directions) to reduce overall sugar while keeping the snickerdoodle-style flavor.
