Fudgy brown-butter chocolate blondie bars topped with a broiler-torched pecan praline crust.
Watch the broiler the entire time it’s on — sugar burns fast, so go in 30-second increments and pull the moment it darkens at the edges. Don’t skip chilling before cutting; warm bars smear the praline into the crumb. Swap pecans for walnuts if that’s what’s on hand, or stir 1 tbsp bourbon into the praline for extra depth. For gluten-free, a 1:1 gluten-free flour blend works but skip the cornstarch. Bars keep in an airtight container at room temperature for 4 days, or freeze layered with parchment for up to 2 months.
