1 teaspoon vanilla extract

Salted Caramel Layer

1 cup unsalted butter
1 cup brown sugar (packed)
1 can (14 oz) sweetened condensed milk
¼ teaspoon salt
1 teaspoon vanilla extract

Chocolate Topping

2 cups semi-sweet or dark chocolate chips
1 tablespoon coconut oil or butter (optional for shine)
Flaky sea salt (for garnish)

Instructions

Step 1: Prepare the Shortbread Base

Preheat your oven to 350°F (175°C) and line a 9×13-inch baking pan with parchment paper.
In a large mixing bowl, cream together softened butter and sugar until light and fluffy.
Add vanilla extract and mix well.
Gradually add flour and salt, mixing until a crumbly dough forms.
Press the dough evenly into the prepared pan.
Bake for 18–20 minutes or until lightly golden.
Remove from oven and let cool completely.

Step 2: Make the Salted Caramel

In a medium saucepan over medium heat, melt butter and brown sugar together.
Stir continuously until the mixture is smooth and bubbling.
Add sweetened condensed milk and continue stirring.
Cook for 5–8 minutes until the caramel thickens and deepens in color.
Remove from heat and stir in salt and vanilla extract.
Pour the caramel over the cooled shortbread base and spread evenly.
Let it cool and set completely (you can refrigerate to speed up this process).

Step 3: Add the Chocolate Layer

Melt chocolate chips in a heatproof bowl using a microwave or double boiler.
Stir until smooth, adding coconut oil if desired for a glossy finish.
Pour the melted chocolate over the caramel layer and spread evenly.
Sprinkle flaky sea salt over the top while the chocolate is still soft.
Allow the chocolate to fully set at room temperature or in the refrigerator.

Step 4: Slice and Serve

Once fully set, lift the dessert out of the pan using parchment paper.
Slice into squares or rectangles using a sharp knife.
Serve and enjoy!
