Instructions

Brown butter in a saucepan over medium heat until golden and nutty.

Remove from heat, pour in a large mixing bowl and stir in milk powder. Let the butter cool for 10-15 minutes.

Preheat oven to 350°F (175°C). Line an 8×8-inch pan with parchment, leaving overhang.

When the butter has cooled, whisk in sugars till fully combined and glossy. It will look a little grainy.

Add in the egg, egg yolk and vanilla extract. Whisk till combined and smooth.

Add flour, cornstarch, salt, baking powder, and baking soda. Fold gently just until combined.

Stir in chocolate.

Press dough evenly into prepared pan using lightly damp fingers or an offset spatula.

Bake for 15-20 minutes, checking early. Edges should be set and golden; center should look slightly underbaked.

Cool in the pan for 10 mins and transfer to a cooling rack to completely.

Tips & Tricks (5)

Master the Brown Butter Stage 🧈
Brown your butter until it reaches a deep golden color with a nutty aroma (about 7-10 minutes), then let it cool completely before mixing—this prevents cooking the eggs and maximizes those caramel notes that define these bars.
Cornstarch is Your Chewy Secret 🎯
The cornstarch in this recipe inhibits gluten development and absorbs moisture, creating that signature chewy texture—don't skip it or substitute with extra flour, as it's crucial to the bar's structure.
Toast Your Espresso Powder First ☕
Bloom the espresso powder in a teaspoon of warm water before adding it to the dough; this unlocks deeper chocolate flavors and prevents grittiness while enhancing the overall complexity.
Strategic Flaky Salt Placement 🧂
Sprinkle flaky sea salt on top of the dough before baking rather than mixing it in, so it stays on the surface and provides contrast to each bite without dissolving into the dough.
Underbake for Maximum Chewiness ⏱️
Remove the bars from the oven when the edges are set but the center still jiggles slightly (a toothpick should have moist crumbs, not be clean)—they'll continue cooking as they cool for perfect chewy texture.
