Millionaire’s Shortbread Is 3 Layers of Heaven

Ingredients

• 225 g Unsalted Butter (room temperature, cut into cubes)
• 100 g Granulated Sugar (for shortbread dough)
• 250 g All-Purpose Flour (sifted)
• 1 g Salt (pinch, for shortbread)
• 397 g Sweetened Condensed Milk (one 14‑oz can)
• 120 ml Lyle's Golden Syrup (toasted cane‑sugar flavor)
• 30 g Unsalted Butter (for caramel, cut into pieces)
• 2 g Salt (pinch, for caramel)
• 5 ml Vanilla Extract (add at end of caramel cooking)
• 200 g Bittersweet Chocolate (70% cocoa, chopped into small pieces)
• 1 sheet Parchment Paper (to line baking pan)

Instructions

1. Cream Butter and Sugar

   In a mixing bowl, beat the room‑temperature butter with the granulated sugar until the mixture is light and fluffy, about 2–3 minutes.

   Time: PT5M

2. Add Dry Ingredients

   Sift the flour and add the pinch of salt. Fold the flour into the butter‑sugar mixture just until the mixture resembles coarse crumbs; do not over‑mix.

   Time: PT5M

3. Press Shortbread into Pan

   Line the 9×13‑inch baking pan with parchment paper. Transfer the crumbly dough to the pan and press it evenly with an offset spatula or your hands, creating a uniform layer.

   Time: PT5M

4. Bake Shortbread

   Bake in a pre‑heated oven at 325°F for 30 minutes, or until the edges are golden brown and the center is set but still tender.

   Time: PT30M

   Temperature: 325°F

5. Cool Shortbread

   Remove the pan from the oven and let the shortbread cool completely in the pan, about 30 minutes.

   Time: PT30M

6. Prepare Caramel Base

   In a saucepan, combine the sweetened condensed milk, Lyle's Golden Syrup, butter, and a pinch of salt. Cook over medium heat, stirring constantly.

   Time: PT5M

7. Cook Caramel to Proper Consistency

   Continue cooking, monitoring with a candy thermometer, until the mixture reaches 220‑225°F and thickens to a pourable but firm consistency (about 10‑12 minutes total).

   Time: PT12M

8. Add Vanilla

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

   Time: PT1M

9. Spread Caramel Over Shortbread

   Pour the hot caramel over the cooled shortbread layer, spreading it evenly with an offset spatula. Allow it to cool completely, about 30 minutes, until firm but still slightly pliable.

   Time: PT30M

10. Melt Chocolate

    Place the chopped bittersweet chocolate in a microwave‑safe bowl. Microwave in 30‑second bursts, stirring between each burst, until fully melted and smooth (about 2 minutes total).

    Time: PT2M

11. Top with Chocolate

    Pour the melted chocolate over the set caramel layer, spreading it into an even thin coat. Let the chocolate set at room temperature, about 15 minutes, or refrigerate briefly to speed up setting.

    Time: PT15M

12. Cut Into Bars

    Using a sharp knife, loosen the edges, then cut the slab into 32 (8 × 4) equal bars. Clean any excess chocolate from the knife between cuts for neat edges.

    Time: PT5M

Critical Steps — Do Not Skip

• Do not overmix the shortbread dough; stop at crumbly texture.
• Monitor caramel temperature closely (220‑225°F) to achieve the right firmness.
• Add vanilla extract after removing caramel from heat to preserve flavor.
• Melt chocolate gently; avoid overheating to prevent scorching.

Chef Tips from the Video

• Use a kitchen scale for precise butter and flour measurements; it yields consistent texture.
• For an extra glossy chocolate finish, brush the top with a thin layer of melted butter after the chocolate sets.
• A light dusting of flaky sea salt on the chocolate adds a sophisticated contrast.
