Unsalted butter
Granulated sugar
Salt
Sweetened condensed milk
Brown sugar

Directions

Preheat oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper.
In a bowl, combine flour, sugar, salt, and softened butter. Mix until crumbly, then press firmly into the bottom of the prepared pan.
Bake the shortbread base for 18–20 minutes, or until lightly golden. Allow to cool.
For the caramel layer, combine butter, brown sugar, corn syrup, and sweetened condensed milk in a saucepan. Cook over medium heat, stirring constantly, until the mixture thickens and reaches a golden caramel color (about 8–10 minutes).
Pour the caramel evenly over the cooled shortbread base. Let it set for 20–30 minutes.
Melt chocolate chips with vegetable oil until smooth. Pour over the caramel layer and spread evenly.
Refrigerate for at least 1–2 hours, or until set.
Slice into bars and enjoy.

FAQs

Can I make these without corn syrup?

Yes, you can substitute honey or golden syrup, though the texture may vary slightly.

How do I keep the caramel from being too hard?

Cook the caramel gently and don’t let it boil too aggressively—it should be thick but still soft when cooled.

Can I use store-bought caramel sauce?

Yes, but homemade caramel holds its shape better in the bars.

What type of chocolate works best?

Milk chocolate gives the classic Twix flavor, but semi-sweet or dark chocolate works for a less sweet version.

How do I cut the bars cleanly?

Use a sharp knife dipped in hot water and wipe between cuts.

Can I make them gluten-free?

Yes, simply use a gluten-free flour blend for the shortbread base.

Do I need a candy thermometer for the caramel?

It helps but isn’t required—cook until the mixture thickens and pulls away slightly from the sides of the pan.

Can I double the recipe?

Yes, but use a larger baking pan or two pans to ensure even layers.

Can I add nuts?

Absolutely, sprinkle chopped nuts over the caramel before adding the chocolate layer.

How long should they chill before slicing?

At least 1–2 hours in the refrigerator ensures clean cuts and firm layers.
