Homemade Twix Bars combine crisp shortbread, a soft caramel layer and a chocolate coating in an easy no-bake treat. With just a few ingredients and time for the caramel to set, they make a fun dessert for parties, office treats or sharing at home. A little coarse sea salt is optional if you enjoy a sweet-and-salty finish.

How to Make Homemade Twix Bars
Start by lining a baking pan with wax paper and lightly misting it with nonstick cooking spray. Arrange the shortbread in the pan. Gently melt the soft caramels with the milk or cream over low to medium heat, stirring as needed. Let the caramel cool briefly, then pour it over the shortbread and spread it into an even layer.
If you like, sprinkle coarse-grain sea salt over the caramel while it is still soft. Leave the pan until the caramel has hardened. This can take several hours; the original method allows it to set overnight. Waiting until the layer is firm makes the bars easier to cut and dip.
Cut and Coat the Bars
Cover a cutting board or other work surface with wax paper and lightly mist it with nonstick cooking spray. Turn the set shortbread and caramel out onto the prepared surface. Cut it into bars, then trim away any caramel that extends beyond the edges.
Melt the chocolate chips with the oil in a microwave-safe glass bowl. Heat on high for 30 seconds at a time, stirring between each interval, until the chocolate is smooth. The original batch took about one minute and 30 seconds in total, but microwave times can vary. Use short heating intervals to help prevent the chocolate from scorching.
Dip each bar in the melted chocolate and let the excess drip or tap off. Place the coated bars on a cooling rack and leave them until the chocolate sets. For a quicker set, place them in the refrigerator and check them periodically.
Ingredients
- Shortbread, in any shape or brand you prefer
- One bag of soft caramels
- One tablespoon milk or cream
- One bag of mini chocolate chips
- Two tablespoons oil
Coarse-grain sea salt is optional. The recipe does not specify pan dimensions or package weights, so the number and size of finished bars will depend on the shortbread and packages you use.
Serving and Preparation Tips
- Choose shortbread pieces that fit closely together in the pan to create a more even base.
- Allow the caramel to cool slightly before pouring so it is easier to handle and spread.
- Cut the bars after the caramel has fully hardened, using a steady motion to keep the layers neat.
- For Halloween trick-or-treating, individually wrapped store-bought candy is the practical option. These homemade bars are better suited to a party, office gathering or dessert table.

Serve the bars once the chocolate coating is set. Homemade Twix Bars are a straightforward way to bring together familiar shortbread, caramel and chocolate flavors without baking.
