Triple Chocolate Salted Caramel Brownie Bars Step-by-step instructions

Before you start

Before starting, line a 9x9-inch baking pan with parchment paper, leaving overhang on two sides. Grate the dark and white chocolate on a box grater and set aside. Measure all ingredients and have them ready.

Heat the oven to 350°F (175°C). If using store-bought caramel sauce, warm it slightly so it is pourable. Ensure the eggs are at room temperature for better incorporation.

Instructions

Prepare the Batter

1. 1Prepare the Pan and Chocolate Curls
   Heat the oven to 350°F (175°C). Line a 9x9-inch baking pan with parchment paper, leaving overhang on two sides. Grate the dark and white chocolate on a box grater into a bowl to create two-tone curls. Set aside.
   Look for The chocolate curls are fine and fluffy, with visible dark and white pieces.
   Tip Chill the chocolate blocks for 10 minutes before grating for cleaner curls.
2. 2Melt the Butter and Chocolates
   In a medium saucepan over low heat, melt the butter with the chopped dark and milk chocolate, stirring frequently until smooth. Remove from heat and let cool slightly.
   Look for The mixture is glossy and completely smooth.
   Tip Do not overheat; remove from the stove as soon as no lumps remain.
3. 3Mix the Wet Ingredients
   In a large bowl, whisk the sugar, eggs, and vanilla extract until pale and slightly thickened. Slowly pour in the melted chocolate mixture, whisking constantly until fully combined.
   Look for The batter is smooth and evenly colored.
   Safe temperature 160°F (71°C) internal temperature (egg dishes)
   Tip Whisk vigorously to avoid scrambling the eggs with the warm chocolate.
4. 4Add the Dry Ingredients
   Sift the flour, cocoa powder, and salt into the wet mixture. Fold gently with a spatula until just combined, with no dry streaks visible.
   Look for The batter is thick and fudgy.
   Tip Do not overmix; fold only until the flour disappears.

At this stage, the batter is smooth, glossy, and thick, with no dry streaks. The chocolate curls are ready, and the oven is preheated.

The batter should be pourable but not runny, and the chocolate mixture has cooled slightly to avoid scrambling the eggs.

Bake and Swirl

5. 5Layer the Brownie Batter
   Pour half of the brownie batter into the prepared pan and spread evenly. Sprinkle a handful of the chocolate curls over the batter. Pour the remaining batter on top and smooth the surface.
   Look for The batter is even and the curls are hidden in the middle.
   Tip Use an offset spatula for a smooth, even layer.
6. 6Add the Caramel and White Chocolate Swirl
   Warm the salted caramel sauce slightly so it is pourable. Drizzle the caramel over the top of the batter. Sprinkle the remaining chocolate curls and the flaky sea salt over the caramel. Use a knife to gently swirl the caramel and chocolate into the top layer.
   Look for The top is marbled with caramel and chocolate ribbons.
   Tip Do not over-swirl; a few passes create a beautiful pattern.
7. 7Bake the Brownie Bars
   Place the pan in the oven and bake for 30 to 35 minutes, until the edges are set and the center is just slightly moist. A toothpick inserted into the center should come out with a few moist crumbs.
   Look for The top is shiny and cracked, and the edges are pulling away from the pan.
   Safe temperature 160°F (71°C) internal temperature (egg dishes)
   Tip Start checking at 25 minutes; ovens vary.
8. 8Cool and Chill
   Let the brownies cool in the pan on a wire rack for 30 minutes. Then transfer the pan to the refrigerator and chill for at least 2 hours, until completely firm.
   Look for The brownies are firm to the touch and easy to slice.
   Tip Chilling makes clean, sharp slices.

The top is shiny and cracked, and the edges are set. The caramel swirl is visible, and the chocolate curls have melted into the top. The center is slightly moist but not jiggly, and the kitchen smells of rich chocolate and caramel.

Slice and Serve

9. 9Slice into Thick Bars
   Lift the chilled brownie slab out of the pan using the parchment overhang. Place on a cutting board. Using a serrated knife, slice the slab into 12 thick bars, wiping the knife between cuts.
   Look for Each bar is thick, with clean edges and a visible layered cross-section.
   Tip For extra clean cuts, dip the knife in hot water and dry it before slicing.
10. 10Serve and Snap
    Arrange the bars on a serving plate. For the signature snap, hold one bar in both hands and break it cleanly in half to reveal the layered interior. Serve immediately.
    Look for The bar snaps crisply, showing fudgy layers and a caramel swirl.
    Tip Serve at room temperature for the best texture.

The chilled slab is firm and easy to slice. Each bar is thick, with clean edges and a visible layered cross-section. When broken, the bar snaps crisply, revealing fudgy layers and a gooey caramel swirl.

Common mistakes

One common mistake is overbaking, which dries out the brownies and makes them cakey instead of fudgy. Start checking at 25 minutes and remove from the oven when the center is still slightly soft.

Another mistake is overmixing the batter after adding the flour, which develops gluten and makes the brownies tough. Finally, do not skip the chilling step—it is essential for clean, sharp slices and a satisfying snap.

How to tell it’s done

The brownies are done when the edges are set and pulling away from the pan, and the center is slightly moist but not jiggly. A toothpick inserted into the center should come out with a few moist crumbs, not wet batter.

The internal temperature of the eggs should reach 160°F (71°C) to ensure they are fully cooked. Let the brownies cool completely before chilling for clean slices.
