Ingredients
For the Shortbread Base
- All-purpose flour – 1½ cups
- Butter – ½ cup, softened
- Sugar – ¼ cup

How to Make Mary Berry Caramel Shortbread
Step 1: Preheat the Oven
Set your oven to 180°C (160°C fan). Line your square tin with parchment paper, leaving a slight overhang so the finished bake lifts out cleanly.
Step 2: Make the Shortbread Base
Combine the flour, butter, and sugar in a mixing bowl. Work it together with your fingertips or a spoon until it forms a soft, even dough, then press it firmly into the base of the tin.
Step 3: Bake the Base
Bake for 15–20 minutes, until the shortbread is pale golden at the edges. Remove from the oven and let it cool slightly while you make the caramel.
Step 4: Prepare the Caramel
Add the butter, brown sugar, and condensed milk to a saucepan. Cook gently over medium heat, stirring constantly so it doesn’t catch on the bottom. The mixture will thicken and turn a deep golden colour after several minutes.
Step 5: Pour the Caramel
Pour the hot caramel evenly over the cooled shortbread base and smooth it out with a spatula. Leave it to cool and firm up slightly before adding the chocolate.
Step 6: Melt the Chocolate
Break the chocolate into small, even pieces and melt it in the microwave in short bursts, or over a double boiler, stirring until smooth and glossy.
Step 7: Add the Chocolate Layer
Pour the melted chocolate over the set caramel and spread it to the edges. Tap the tin gently on the counter to level the surface.
Step 8: Chill and Set
Transfer the tin to the fridge for 1–2 hours, until every layer is firm and the chocolate has set completely.
Step 9: Slice and Serve
Lift the traybake out using the parchment overhang and cut it into neat squares with a sharp knife. Serve and enjoy.

History of Millionaire’s Shortbread
Caramel shortbread earned its nickname “millionaire shortbread” because of how rich and indulgent it tastes. The three-layer combination of shortbread, caramel, and chocolate became a staple of British home baking, prized for looking far more elaborate than it actually is to make. Today it’s a fixture at bake sales, afternoon teas, and dessert tables across the UK and well beyond.
Serving Suggestions
Caramel shortbread pairs naturally with a cup of tea or coffee, which helps balance out its sweetness. Fresh berries add a tart contrast to the rich layers, and a scoop of vanilla ice cream turns a simple square into a full dessert.
