The Ultimate Millionaire’s Shortbread Recipe

Millionaire’s Shortbread is an indulgent, three-layered dessert that combines a crisp, buttery shortbread base, a rich and chewy caramel center, and a glossy, luscious chocolate topping. This luxurious treat is reminiscent of Twix bars, yet homemade versions bring an unparalleled depth of flavor and texture.

A Brief History of Millionaire’s Shortbread

Originating from Scotland, shortbread has long been a staple in British baking, dating back to the 12th century. The addition of caramel and chocolate to form Millionaire’s Shortbread is believed to have started in the 20th century, elevating the simple shortbread into a truly indulgent dessert worthy of its opulent name.

Ingredients for Millionaire’s Shortbread

For the Shortbread Base:

• 1 cup (226g) unsalted butter, softened
• ½ cup (100g) granulated sugar
• 2 cups (250g) all-purpose flour
• ½ teaspoon salt
• 1 teaspoon vanilla extract (optional, for extra flavor)

For the Caramel Layer:

• 1 cup (226g) unsalted butter
• 1 cup (200g) packed brown sugar
• 1 (14 oz) can sweetened condensed milk
• ¼ cup (60ml) light corn syrup (prevents crystallization)
• ½ teaspoon salt
• 1 teaspoon vanilla extract

For the Chocolate Topping:

• 10 oz (280g) semi-sweet or dark chocolate, finely chopped
• 2 tablespoons (30g) unsalted butter (for a smooth, glossy finish)

Step-by-Step Instructions

Step 1: Prepare the Shortbread Base

1. Preheat the oven to 350°F (175°C) and line a 9×13-inch baking dish with parchment paper, leaving an overhang for easy removal.
2. In a mixing bowl, cream the butter and sugar together until light and fluffy.
3. Add the flour and salt, mixing until a crumbly dough forms.

1. Press the dough evenly into the prepared pan and prick the surface with a fork to prevent puffing.
2. Bake for 20-25 minutes, or until golden brown.
3. Allow to cool completely before adding the caramel layer.

Step 2: Make the Caramel Filling

1. In a heavy-bottomed saucepan, melt the butter over medium heat.
2. Stir in the brown sugar, sweetened condensed milk, and corn syrup.
3. Bring to a gentle boil, stirring continuously to prevent burning.
4. Cook for 6-8 minutes, or until the caramel thickens and reaches a deep golden color (235-240°F on a candy thermometer).
5. Remove from heat, stir in the vanilla extract and salt, then pour over the cooled shortbread base.
6. Let it set at room temperature for at least 1 hour or until firm.

Step 3: Prepare the Chocolate Topping

1. Melt the chopped chocolate and butter in a double boiler or microwave in 30-second intervals, stirring until smooth.
2. Pour the melted chocolate over the set caramel layer, spreading evenly with an offset spatula.
3. Tap the pan gently on the counter to release any air bubbles.

Step 4: Chill and Serve

1. Refrigerate for at least 2 hours, or until the chocolate is fully set.
2. Use a sharp knife to cut into squares or bars.
3. Enjoy your homemade Millionaire’s Shortbread!
