Step-by-Step Instructions

Prepare the Brownie Base

Preheat your oven to350°F (175°C). Line an 8 × 8-inch square baking pan with parchment paper, leaving a little overhang on the sides.

In a heatproof bowl, combine the butter and chopped semi-sweet chocolate. Melt them together using a microwave in short intervals, stirring between each interval, or place the bowl over a saucepan of gently simmering water. Stir until completely smooth, then allow the mixture to cool slightly.

In a separate large mixing bowl, whisk together the granulated sugar, brown sugar, and eggs until smooth and well combined. Add the vanilla extract and melted chocolate mixture, stirring until incorporated.

Sift in the flour, cocoa powder, and salt. Gently fold the dry ingredients into the chocolate mixture until just combined. Avoid overmixing to keep the brownies fudgy.

Bake the Brownies

Pour the brownie batter into the prepared baking pan and spread it evenly with a spatula.

Bake for20–25 minutes, or until the edges are set and a toothpick inserted near the center comes out with a few moist crumbs.

Remove from the oven and let the brownies cool completely in the pan. The brownie base must be completely cool before adding the caramel layer.

Make the Homemade Caramel

Add the butter, brown sugar, sweetened condensed milk, and corn syrup to a medium saucepan.

Heat over medium-low heat, stirring continuously with a rubber spatula to prevent the mixture from sticking or burning. Continue cooking for about8–12 minutes, until the caramel thickens and develops a smooth, golden color.

Remove the saucepan from the heat and stir in the vanilla extract and salt.

Allow the caramel to cool for a few minutes, then pour it over the cooled brownie base. Spread it evenly using a spatula.

Refrigerate for about45–60 minutes, or until the caramel layer is firm enough to support the chocolate topping.

Prepare the Chocolate Topping

Place the chopped chocolate and coconut oil in a heatproof bowl.

Melt in the microwave in 20-second intervals, stirring after each interval until smooth. Alternatively, melt gently over a saucepan of simmering water.

Let the melted chocolate cool slightly, then pour it over the chilled caramel layer. Spread evenly to cover the entire surface.

If desired, sprinkle a little flaky sea salt over the chocolate before it sets.

Chill Until Set

Place the pan in the refrigerator for approximately1 hour, or until the chocolate topping is firm.

Once fully set, lift the brownies out of the pan using the parchment paper overhang. Transfer them to a cutting board and slice into 16 squares using a sharp knife.

For cleaner cuts, warm the knife under hot water, wipe it dry, and clean it between slices.

Helpful Tips for Perfect Millionaire Brownies

• Don’t overbake the brownie base:A slightly fudgy center creates the best texture beneath the caramel.
• Stir the caramel continuously:This prevents scorching and helps create a smooth, thick filling.
• Watch the caramel temperature:Keep the heat moderate and avoid rushing the cooking process.
• Cool each layer properly:Adding caramel to warm brownies or chocolate to soft caramel can cause the layers to mix.
• Use good-quality chocolate:It makes a noticeable difference in the flavor and texture of the topping.
• Slice with a warm knife:This helps prevent the chocolate layer from cracking into uneven pieces.

Storage tip:Keep the brownies covered in the refrigerator until ready to serve. Let them sit at room temperature for about 10–15 minutes before eating for a softer caramel layer and fudgier brownie texture.
