🍯 Caramel Shortbread (Millionaire’s Shortbread)

🕒 Prep: 25 min | Cook: 30 min | Chill: 2+ hrs

🍽️ Makes: ~16 squares

🧂 Ingredients

🔹 Shortbread Base:

1 cup (2 sticks) unsalted butter, softened
½ cup granulated sugar
2 cups all-purpose flour
¼ tsp salt

🔹 Caramel Layer:

1 can (14 oz) sweetened condensed milk
½ cup brown sugar
½ cup (1 stick) unsalted butter
2 tbsp corn syrup (or golden syrup)
Pinch of salt
1 tsp vanilla extract

🔹 Chocolate Topping:

1 ½ cups semi-sweet or milk chocolate chips
1 tbsp butter or cream (optional, for smoother texture)

👨‍🍳 Instructions

1. Make the Shortbread

Preheat oven to 350°F (175°C). Line an 8×8-inch pan with parchment paper.
Cream butter and sugar until light and fluffy.
Mix in flour and salt until it forms a soft dough.
Press evenly into the pan. Prick with a fork.
Bake for 20–25 minutes, or until lightly golden. Let cool.

2. Make the Caramel Layer

In a saucepan, combine condensed milk, brown sugar, butter, and corn syrup.
Cook over medium-low heat, stirring constantly, for 10–15 minutes, until thick and golden.
Remove from heat. Stir in vanilla and a pinch of salt.
Pour over the cooled shortbread and spread evenly. Let cool completely or chill for 30+ minutes.

3. Add the Chocolate Layer

Melt chocolate and butter (or cream) together in a microwave or double boiler.
Pour over the set caramel layer and spread smooth.
Chill for 1–2 hours, or until firm.

4. Cut and Serve

Use a sharp knife, dipped in hot water and wiped dry, to slice cleanly.
Store in an airtight container in the fridge for up to a week.

✅ Tips

For salted caramel: Sprinkle flaky sea salt over the caramel layer before adding chocolate.
Crumbly shortbread? Press the dough firmly and evenly.
Want a twist? Add crushed pretzels, toffee bits, or espresso powder to the chocolate layer.
