Ingredients
Butter
- 1/2 cup (110g) + 1 tbsp unsalted butter*
Sugars
- 1/2 cup (100g) dark brown sugar, packed
- 1/4 cup (50g) granulated sugar
Wet Ingredients
- 1 large egg
- 1 1/2 tsp vanilla bean paste
Dry Ingredients
- 1 1/4 cups (165g) all purpose flour
- 1/2 tsp baking powder
- 3/4 tsp kosher salt
Add-ins & Toppings
- 1 cup (185g) semisweet chocolate chips, plus more for sprinkling on top
- Flaky sea salt, for sprinkling
Instructions
- Brown the Butter: Place 1/2 cup of unsalted butter in a saucepan over medium heat. Stir constantly as the butter melts, becoming bubbly and loud, then turning quiet and frothy. Continue watching carefully until the butter turns a golden amber color and releases a nutty aroma, then immediately remove from heat.
- Measure and Cool Butter: Pour the browned butter into a measuring glass. Add the remaining 1 tablespoon of butter to make an exact 1/2 cup measurement, which may require slightly more or less butter. Transfer to the refrigerator to cool while preparing other ingredients.
- Prepare Baking Pan and Oven: Preheat oven to 350°F (175°C). Grease and line an 8×8 inch square baking dish with parchment paper, allowing the paper to hang over sides for easy removal.
- Mix Dry Ingredients: In a small bowl, whisk together the all-purpose flour, baking powder, and kosher salt. Set aside.
- Combine Sugars and Butter: In a large mixing bowl, whisk together the dark brown sugar, granulated sugar, and the cooled browned butter. It is fine if the butter is slightly warm but not hot.
- Add Egg and Vanilla: Whisk the vanilla bean paste and egg into the butter and sugar mixture until incorporated.
- Incorporate Dry Ingredients: Switch to a rubber spatula and gently fold in the dry ingredients. When some flour patches remain, add in the semisweet chocolate chips.
- Fold Dough and Prepare to Bake: Fold the dough until combined. Spread the dough evenly into the prepared baking pan. Sprinkle additional chocolate chips over the surface and gently press them into the dough.
- Bake Bars: Bake in the preheated oven for 25-30 minutes, until the edges turn a light golden brown and the center appears evenly puffed but slightly soft.
- Add Sea Salt and Cool: Immediately after removing from the oven, sprinkle the top with flaky sea salt.
- Cool Bars: Allow the bars to cool in the pan at room temperature for about 45 minutes, or place in the refrigerator to chill faster.
- Slice and Serve: Once cooled but still slightly warm, lift the bars out of the pan using the parchment paper overhang. Slice into 16 squares and enjoy!
Notes
- Make sure the browned butter is cooled to avoid cooking the egg when mixing.
- The sea salt topping enhances the sweetness and chocolate flavors.
- You can speed up the cooling process by refrigerating the bars before slicing.
- Adjust baking time slightly depending on your oven; bars should be soft in the center but firm at edges.
- Using parchment paper makes removal and slicing much easier and cleaner.
