Millionaire Shortbread Bars. Layered shortbread squares with cooked caramel and a thin semisweet chocolate top. The formula and timing below are working estimates for a future kitchen trial, not a claim that a batch has been made.

Three clear layers
Millionaire shortbread gets its contrast from a crisp butter base, soft cooked caramel and a thin chocolate lid. Small squares make sense because the middle is rich.
This is a working formula. The caramel's exact endpoint and clean sixteen-bar cut need testing rather than a promise of a flawless slab.
Bake the base first
Cut cold butter into flour and confectioners' sugar, press firmly and bake until pale gold. An underbaked base can crumble or soften beneath caramel.
Line the pan with enough parchment to lift the finished bars. A glass pan may change the base bake; the card specifies metal.
Ingredients for 16 bars
| Ingredient | Amount | Use |
|---|---|---|
| All-purpose flour | 1 1/4 cups | Shortbread. |
| Confectioners' sugar | 1/4 cup | Shortbread. |
| Unsalted butter, for base | 8 tablespoons | Cold cubes. |
| Fine salt | 1/8 teaspoon | Base. |
| Sweetened condensed milk | 14 ounces | One can for caramel. |
| Light brown sugar, packed | 1/2 cup | Caramel. |
| Unsalted butter, for caramel | 4 tablespoons | Caramel. |
| Semisweet chocolate, chopped | 6 ounces | Top. |
| Neutral oil | 1 teaspoon | Stir into melted chocolate. |
Step-by-step method
- Heat oven to 350°F and line an 8-inch pan with parchment. Cut 8 tbsp cold butter into 1 1/4 cups flour, 1/4 cup confectioners' sugar and 1/8 tsp salt. Press evenly and bake about 18–20 minutes until pale golden. Cool briefly.
- In a heavy saucepan combine one 14-oz can sweetened condensed milk, 1/2 cup packed brown sugar and 4 tbsp butter. Stir continuously over medium-low heat about 10–15 minutes until thick, amber and pulling from the pan; avoid scorching. Spread over the shortbread.
- Cool caramel to room temperature. Melt 6 oz chopped semisweet chocolate gently with 1 tsp neutral oil, spread thinly over caramel and refrigerate until layers are firm, allowing about three hours total cooling and chilling.
- Lift with parchment and cut sixteen small squares using a warmed, wiped knife. Test caramel set, shortbread strength and chocolate cracking before approving.
Watch the caramel
Stir condensed milk, brown sugar and butter constantly over moderate-low heat. It should visibly thicken without scorched flecks; a heavy pan helps distribute heat.
Brand formulation and heat affect set. If it remains fluid after cooling, record cook time and visual appearance before changing ratios.
Finish with chocolate
Melt chopped chocolate gently with a teaspoon of oil and spread a thin layer over cooled caramel. Pouring it onto steaming caramel can muddy the layers.
Chill until firm. A very cold thick lid may snap when cut, so a warmed clean knife can help; its performance needs a real trial.
Storage and portions
Cut four rows each way for sixteen modest pieces. Keep covered under suitable conditions and assess caramel softness before setting a quality window.

Shortbread questions
Is the caramel uncooked condensed milk?
No. The milk, brown sugar and butter are stirred over heat until thick.
Can I skip the chill?
Not for the planned clean layers; allow cooling and setting before cutting.
How many pieces?
Sixteen small squares are the provisional yield.
