Recipe FAQs

What makes the blondies chewy?

The combination of melted butter and packed light brown sugar creates a moist, dense texture that results in chewy blondies.

How is the salted caramel prepared?

Sugar and water are heated until amber, then butter and cream are stirred in, finishing with a pinch of flaky sea salt to create a smooth, rich caramel sauce.

Can I add nuts to these bars?

Yes, folding in toasted pecans or walnuts adds a pleasant crunch and nutty flavor without altering the core texture.

How-To Steps

Step 01

Preheat Oven and Prepare Pan: Preheat oven to 350°F. Line a 9x9-inch baking pan with parchment paper, leaving an overhang for easy removal.

Step 02

Prepare Caramel Sauce: In a medium saucepan, combine granulated sugar and water. Stir over medium heat until sugar dissolves, then simmer without stirring until deep amber color forms, about 4 to 6 minutes. Remove from heat, add butter, and stir until melted.

Incorporate Dry Ingredients: Add all-purpose flour, baking powder, and fine sea salt to the wet mixture. Stir just until combined; avoid overmixing.

Step 05

Assemble Layers: Spread two-thirds of the blondie batter evenly in the prepared pan. Drizzle two-thirds of the caramel sauce over batter. Spoon remaining blondie batter on top and gently swirl with a knife. Drizzle remaining caramel over surface; swirl again.

Step 06

Add Finishing Touch and Bake: Sprinkle extra flaky sea salt over the top. Bake for 28 to 32 minutes, until edges are golden and a toothpick inserted in the center comes out with moist crumbs.
