Twix Cookie Bars Recipe
Introduction
Twix Cookie Bars bring together a buttery shortbread base, a rich caramel layer, and a smooth chocolate topping for a delightful homemade treat. These bars are an easy way to satisfy your sweet tooth with classic flavors in every bite.

Ingredients
- 2 cups (250g) all-purpose flour
- 1 cup (200g) granulated sugar
- 1 cup (225g) salted butter, softened
- 1 can (14 oz / 396g) sweetened condensed milk
- 1 teaspoon vanilla extract
- 1 ½ cups (270g) semisweet chocolate chips
- Sea salt flakes (optional, for sprinkling)
Instructions
- Step 1: Preheat your oven to 350°F (175°C). In a large bowl, cream together the softened butter and granulated sugar until the mixture is light and fluffy, about 3 to 4 minutes. Stir in the vanilla extract.
- Step 2: Gradually mix in the flour until the dough just comes together. Press the dough evenly into a lined 9×13-inch baking pan, packing it down firmly to create the shortbread base.
- Step 3: Bake the base for 18 to 20 minutes, until the edges turn golden but the center remains slightly soft. Remove the pan from the oven.
- Step 4: While the shortbread is still warm, pour the sweetened condensed milk evenly over the base. Use a spatula to spread it smoothly.
- Step 5: Return the pan to the oven and bake for another 15 minutes, until the caramel bubbles and takes on a light golden color.
- Step 6: Let the caramel layer cool for about 10 minutes. Meanwhile, melt the chocolate chips in 30-second intervals in the microwave or use a double boiler until smooth.
- Step 7: Pour the melted chocolate over the caramel layer and spread it evenly. Sprinkle sea salt flakes on top if you like a touch of saltiness.
- Step 8: Chill the bars in the refrigerator for at least 2 hours until the chocolate is firm.
- Step 9: Lift the bars out by the parchment paper edges and slice into squares or rectangles. Warm and dry your knife under hot water for clean cuts.
Tips & Variations
- For a richer caramel flavor, try adding a pinch of sea salt to the condensed milk layer before baking.
- Substitute semisweet chocolate chips with milk chocolate or dark chocolate depending on your preference.
- Use parchment paper to line your pan for easy removal and cleaner edges when slicing.
Storage

FAQs
Can I make these bars without sweetened condensed milk?
Sweetened condensed milk is essential for the caramel layer in this recipe. For an alternative, you would need to prepare a homemade caramel sauce, but the texture and flavor may differ.
How do I prevent the chocolate from cracking when slicing the bars?
Use a sharp knife warmed under hot water and dried before slicing. This helps make smooth cuts without cracking the chocolate layer.
