Step-by-Step Instructions
Step 1: Prepare the Pan
-
Line a 9×9-inch square baking pan with parchment paper, leaving some overhang for easy removal.
Step 2: Make the Shortbread Base
-
Preheat oven to 350°F (175°C).
-
In a large bowl, cream butter and sugar together until light and fluffy.
-
Add flour and salt. Mix until crumbly dough forms.
-
Press dough evenly into prepared pan.
-
Bake for 20–22 minutes until lightly golden. Remove and let cool.
Tip: Use the bottom of a flat glass or measuring cup to press the dough evenly.
Step 3: Make the Caramel Layer
-
In a medium saucepan over medium-low heat, combine:
-
Sweetened condensed milk
-
Butter
-
Brown sugar
-
Golden syrup
-
Salt
-
-
Stir constantly until butter melts, then increase heat slightly and bring to a gentle simmer.
-
Cook for 8–10 minutes, stirring frequently, until thickened and golden.
Don’t walk away—caramel can burn quickly!
-
Pour caramel over the cooled shortbread base and smooth evenly.
-
Chill in the fridge for at least 30 minutes until set.
Step 4: Add the Chocolate Topping
-
In a microwave-safe bowl, melt:
-
Chocolate chips
-
Butter or oil
Microwave in 20-second bursts, stirring between each until smooth.
-
-
Pour melted chocolate over the caramel layer. Smooth with a spatula.
-
Chill again for 1–2 hours or until chocolate is fully set.
Step 5: Cut and Serve
-
Use parchment to lift the slice from the pan.
-
Run a sharp knife under hot water, wipe dry, and slice into 16 squares.
Tip: Scoring the chocolate before it’s fully hardened prevents it from cracking unevenly when cutting.
