Make the salted caramel. Add sugar to a clean pan. Heat the sugar over low - medium heat for about 5 - 6 minutes or until the sugar starts to melt and turns an amber color. Once the sugar has done this, remove the pan from the heat and add the butter. Stir the butter in for 1 - 2 minutes. Move the pan back onto the heat and add the heavy cream. Stir the heavy cream into the melted butter sugar mixture for 1 minute. Remove the pan from the heat once again. Stir in the vanilla and salt until well combined. Pour the hot caramel into a heat safe container. If you plan on making homemade caramel, allow about 10 minutes to make the caramel and another 20 - 30 for the caramel to cool enough to use in the brownie recipe. 1 cup (200 g) granulated sugar, 6 tablespoons (85 g) unsalted butter, ½ cup (120 ml) heavy cream, room temperature, 1 teaspoon salt, ½ teaspoon vanilla extract
Preheat the oven to 350 F (177 C). Line a 8x8 (20 cm) or 9x9 (23 cm) pan with parchment paper along the bottom and two sides. Repeat with another strip of parchment paper to cover the other two sides.
In a microwave safe mixing bowl add the butter and 1 cup of dark chocolate chips. Heat in 30 second increments, stirring after each until the butter and chocolate are fully melted and mixed together. Whisk in the espresso powder and set aside for a moment.
1 cup (226 g) unsalted butter, sliced, 1½ cups (9 oz, 255 g) dark chocolate, divided, 1 teaspoon espresso powder
In another mixing bowl whisk the eggs, sugar, light brown sugar, vanilla extract and salt until smooth and well combined. Whisk in the melted chocolate and butter mixture until smooth and well combined. Whisk in the cocoa powder and flour until smooth and glossy. Stir in the remaining ½ cup (85 g) chocolate chips.
3 large eggs, room temperature, ¾ cup (150 g) light brown sugar, ½ cup (100 g) granulated sugar, 2 teaspoons (10 ml) vanilla extract , ½ cup (40 g) Dutch processed or dark cocoa powder , ½ teaspoon salt , ¾ cup (90 g) all purpose flour
Evenly pour ½ of the brownie batter into the prepared pan. Swirl in about ¾ cup (180 ml) cooled salted caramel into the brownie batter. Top with the remaining brownie batter. Bake the brownies for about 30 - 40 minutes. For a 9 x 9 pan, the baking time should range for 30 - 35 minutes. For 8 x 8 pan, the baking time should range for 35 - 40 minutes. Cool the brownies in the pan for 1 hour. Then transfer the brownies to cool in the fridge for about 30 - 45 minutes or leave to cool at room temperature for an additional 45 - 60 minutes. Top with more salted caramel and enjoy.
