Ingredients:
- 1 cup unsalted butter, softened
- 0.75 cup light brown sugar, packed
- 0.5 cup granulated cane sugar
- 2 large eggs
- 1 tablespoon vanilla bean paste
- 2.33 cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon cornstarch
- 1.5 cups dark chocolate chips (70% cacao)
- 14 oz soft caramels, unwrapped
- 0.33 cup heavy whipping cream
- 1 teaspoon flaky sea salt
- 1 tablespoon all-purpose flour (for caramel stabilization)
Instructions:
- Preheat and Prep. Set your oven to 350°F (175°C). Line your 9x13 inch metal pan with parchment paper, leaving an overhang on the long sides. Note: This ensures even heat and easy removal.
- Cream the Base. In your mixer, beat the 1 cup softened butter, 0.75 cup light brown sugar, and 0.5 cup granulated sugar for 3 to 4 minutes until the mixture looks pale, fluffy, and like soft clouds.
- Incorporate Liquids. Add the 2 large eggs one at a time, beating well after each. Mix in the 1 tablespoon vanilla bean paste until the aroma of vanilla fills the air.
- Fold Dry Ingredients. Gently stir in the 2.33 cups all purpose flour, 1 teaspoon baking soda, and 1 teaspoon cornstarch. Stop as soon as no white streaks remain to keep the bars tender.
- Add Chocolate. Fold in the 1.5 cups dark chocolate chips. Note: Stirring too much here can toughen the dough.
- Press the Base. Press exactly two thirds of this dough into the bottom of your pan. Use the back of a spoon or damp fingers to get an even layer until the bottom is completely covered.
- Melt the Caramel. In your heavy saucepan over medium low heat, combine the 14 oz soft caramels, 0.33 cup heavy cream, and 1 tablespoon flour. Whisk until you have a smooth, velvety liquid with no lumps.
- Layer and Salt. Pour the caramel over the dough base. Sprinkle the 1 teaspoon flaky sea salt evenly across the surface. The contrast of white salt on amber caramel is stunning.
- Crumble and Bake. Break the remaining dough into small bits and scatter them over the caramel. Bake for 35 minutes until the edges are a deep golden brown and the top smells like toasted sugar.
- The Long Wait. Let the bars cool in the pan for at least 2 hours. Note: This is the hardest part, but the caramel must set or it will run everywhere when sliced.
