Ingredients
- For the Shortbread Cookie Base:
- 2 ½ cups (300g) all-purpose flour
- ½ cup (100g) granulated sugar
- ¼ teaspoon salt
- 1 cup (226g) unsalted butter, cold and cubed
- 1 teaspoon vanilla extract
- 1-2 tablespoons cold water (if needed)
- For the Caramel Filling:
- 1 cup (226g) unsalted butter
- 1 ¾ cups (350g) granulated sugar
- ½ cup light corn syrup
- ½ cup heavy cream
- 1 teaspoon vanilla extract
- ½ teaspoon salt
- For the Chocolate Topping:
- 12 oz (340g) good quality milk chocolate, chopped (or semi-sweet if preferred)
- 1 tablespoon vegetable oil or coconut oil (optional, for a smoother coating)
Instructions
- Prepare the Shortbread Cookie Base:
- Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides to easily lift the cookies out later. This is a crucial step for easy removal and cutting.
- In a large bowl, whisk together the all-purpose flour, granulated sugar, and salt.
- Add the cold, cubed unsalted butter to the flour mixture. Using a pastry blender, your fingertips, or a food processor, cut the butter into the flour until the mixture resembles coarse crumbs. If using a food processor, pulse gently to avoid overmixing.
- Stir in the vanilla extract. If the dough seems too dry and isn’t coming together, add cold water, one tablespoon at a time, mixing lightly after each addition, until the dough just starts to clump. Be careful not to add too much water.
- Press the shortbread dough evenly into the bottom of the prepared baking pan. Use the bottom of a measuring cup or your hands to create a flat, compact layer.
- Prick the dough all over with a fork. This helps prevent the shortbread from puffing up too much during baking.
- Bake for 20-25 minutes, or until the edges are lightly golden and the surface is pale gold. Don’t overbake, as it will continue to firm up as it cools.
- Remove from the oven and let the shortbread cool completely in the pan on a wire rack. This can take about 1-2 hours. It’s important for the base to be cool before adding the caramel.
- Prepare the Caramel Filling:
- While the shortbread is cooling, or once it has cooled, prepare the caramel. In a medium, heavy-bottomed saucepan, combine the unsalted butter, granulated sugar, light corn syrup, and heavy cream.
- Cook over medium heat, stirring constantly with a wooden spoon or heatproof spatula, until the butter is melted and the sugar is dissolved. It’s important to keep stirring to prevent the sugar from burning at the bottom of the pan.
- Once the mixture comes to a boil, reduce the heat to medium-low and continue to cook, stirring frequently, until the caramel reaches 245-250°F (118-121°C) on a candy thermometer. This is the firm-ball stage and will ensure your caramel sets up properly but remains chewy. This process can take 15-25 minutes depending on your stove. If you don’t have a candy thermometer, you can test by dropping a small amount of caramel into a glass of cold water; it should form a firm but pliable ball.
- Once the caramel reaches the correct temperature, immediately remove the saucepan from the heat. Carefully stir in the vanilla extract and salt. The mixture will bubble up, so be cautious.
- Pour the hot caramel evenly over the cooled shortbread base. Tilt the pan gently to spread the caramel into an even layer.
- Let the caramel layer cool and set completely. This can take at least 2-3 hours at room temperature, or you can speed up the process by placing it in the refrigerator for about 1-1.5 hours once it’s no longer hot to the touch. The caramel should be firm to the touch before adding the chocolate.
- Prepare the Chocolate Topping and Assemble:
- Once the caramel layer is completely set, prepare the chocolate topping. Place the chopped milk chocolate (and optional vegetable or coconut oil) in a microwave-safe bowl.
- Microwave in 30-second intervals, stirring well after each interval, until the chocolate is fully melted and smooth. Be careful not to overheat or seize the chocolate. Alternatively, you can melt the chocolate in a heatproof bowl set over a pan of simmering water (double boiler method), ensuring the bottom of the bowl doesn’t touch the water.
- Pour the melted chocolate over the set caramel layer. Quickly spread it into an even layer using an offset spatula or the back of a spoon.
- Let the chocolate set. You can let it set at room temperature for several hours (2-4 hours) until firm, or for a quicker set, place it in the refrigerator for about 30-60 minutes. If refrigerating, be aware that condensation might form on the chocolate surface. To minimize this, you can loosely cover the pan.
- Cut and Serve:
- Once the chocolate is completely set, use the parchment paper overhangs to lift the entire slab out of the pan and onto a cutting board.
- For best results when cutting, use a large, sharp knife. You can warm the knife by running it under hot water and then drying it thoroughly before each cut. This helps to cut through the chocolate and caramel layers cleanly.
- Cut into desired shapes. Traditional Twix bars are long and rectangular, so you might cut them into approximately 1×3 inch bars. You can also cut them into squares or smaller “fun-size” pieces.
- Store the Twix Cookies in an airtight container at room temperature for up to 5 days, or in the refrigerator for up to 2 weeks. If stacking, place parchment paper between layers to prevent sticking.

How to Serve
These homemade Twix Cookies are wonderfully versatile and can be enjoyed in numerous ways. Here are some serving suggestions to make the most of your delicious creation:
- Classic Treat: Enjoy a bar on its own with a tall glass of cold milk – the quintessential cookie experience.
- Coffee or Tea Companion: The rich caramel and chocolate pair beautifully with a hot cup of coffee, tea, or even a latte for an afternoon pick-me-up.
- Dessert Platter Star: Cut them into smaller, bite-sized pieces and arrange them on a dessert platter alongside other cookies, fruits, or brownies for parties and gatherings. Their distinct layers make them visually appealing.
- Ice Cream Topping: Crumble a Twix Cookie over a bowl of vanilla bean or caramel ice cream for an extra decadent dessert. The textural contrast is fantastic.
- Party Favors: Wrap individual bars in cellophane bags tied with a ribbon for charming and delicious party favors or small gifts.
- Holiday Baking Trays: These cookies are a fantastic addition to holiday cookie exchanges or festive baking trays, offering a unique alternative to more common cookies.
- Slightly Warmed: For an extra gooey caramel experience, you can very briefly warm a cookie in the microwave for just 5-7 seconds before eating (be careful, caramel can get very hot).
- With a Pinch of Sea Salt: If you love a sweet and salty combination, sprinkle a tiny pinch of flaky sea salt over the chocolate topping just before it sets.
Additional Tips
To ensure your “Cooking With Karli” style Twix Cookies turn out perfectly every time, consider these helpful tips:
- Quality Ingredients Matter: For the best flavor, use good quality butter, chocolate, and vanilla extract. The difference is noticeable, especially in a recipe with distinct layers like this. For the chocolate, a couverture chocolate will melt beautifully and give a nice snap.
- Patience with Caramel: Making caramel requires patience. Stir constantly to prevent burning and use a candy thermometer for accuracy. If you don’t have one, the cold water test is a good alternative, but a thermometer removes guesswork. Don’t rush the cooling process for the caramel layer either; it needs to be firm before adding chocolate.
- Perfect Chocolate Melting: When melting chocolate, go low and slow. Whether using a microwave or a double boiler, avoid overheating, which can cause it to seize and become grainy. Adding a teaspoon of coconut oil or neutral vegetable oil can help create a smoother, glossier chocolate coating that’s easier to spread.
- Clean Cutting: For those picture-perfect, clean-cut bars, ensure each layer is fully set. A hot, dry knife is your best friend. Run a large, sharp knife under hot water, wipe it dry, make a cut, and repeat. This prevents the chocolate from cracking too much and the caramel from sticking. Scoring the chocolate layer before it fully sets can also help guide your cuts.
- Storage Savvy: Store your Twix Cookies in an airtight container. At room temperature, they’ll last for about 5 days. If you live in a very warm or humid climate, or for longer storage (up to 2 weeks), keep them in the refrigerator. If refrigerated, let them sit at room temperature for 10-15 minutes before serving for the best texture, as the caramel can become quite firm when cold. For even longer storage, these cookies freeze well for up to 3 months if wrapped tightly.
Budgeting the Recipe
Creating these delightful Twix Cookies at home, much like many “Cooking With Karli” recipes, can be a surprisingly budget-friendly endeavor compared to buying individual candy bars or gourmet cookies from a bakery. While the initial outlay for ingredients like butter, chocolate, and sugar might seem like a bit, these are often pantry staples or can be bought in larger quantities for better value if you bake regularly.
Consider the yield: this recipe typically makes 24-30 substantial bars. If you were to purchase that many premium candy bars, the cost would likely be significantly higher. Making them at home allows you to control the quality of ingredients and often results in a superior product for a fraction of the price per serving. Look for sales on butter and chocolate, especially around baking holidays. Buying all-purpose flour and sugar in bulk if you have storage space is another way to reduce costs over time. Even specialty items like light corn syrup or heavy cream are often more economical when used across multiple homemade treats rather than buying single-serving processed snacks. The satisfaction of creating something so delicious from scratch, coupled with the cost savings per bar, makes this Twix Cookie recipe a winner for both your taste buds and your wallet.
Frequently Asked Questions
Q: Can I make these Twix Cookies gluten-free?
A: Yes, you can adapt this recipe to be gluten-free. For the shortbread base, substitute the all-purpose flour with a good quality gluten-free all-purpose flour blend that contains xanthan gum. If your blend doesn’t include it, you may need to add about ½ to ¾ teaspoon of xanthan gum. The texture might be slightly different, but it should still be delicious. Ensure all other ingredients, like your chocolate, are certified gluten-free if catering to a strict dietary need.
Q: My caramel layer is too hard/too soft. What went wrong?
A: The consistency of the caramel is highly dependent on the temperature it’s cooked to. If your caramel is too hard, it was likely cooked to too high a temperature (beyond the firm-ball stage). If it’s too soft and runny, it probably didn’t reach the necessary 245-250°F (118-121°C). Using a candy thermometer is the best way to ensure accuracy. Also, ensure you’re cooking it long enough for sufficient water to evaporate.
Q: Can I use dark chocolate or white chocolate instead of milk chocolate for the topping?
A: Absolutely! The chocolate topping is very versatile. Dark chocolate (semi-sweet or bittersweet) will provide a richer, less sweet contrast to the sweet caramel and shortbread. White chocolate would make for an even sweeter, creamier version. Feel free to use your favorite type of chocolate or even a mix. Just ensure it’s a good quality melting chocolate for the best results.
Q: How far in advance can I make these Twix Cookies?
A: These cookies hold up well. You can make them 2-3 days in advance if stored properly in an airtight container at room temperature. If you need to make them further ahead, they can be refrigerated for up to 2 weeks or frozen for up to 3 months. If freezing, thaw them in the refrigerator or at room temperature before serving. This makes them a great option for planning ahead for parties or events.
Q: My shortbread base is too crumbly or too hard. Any tips?
A: If your shortbread is too crumbly, it might be that the dough was too dry (needed a bit more water) or it wasn’t pressed firmly enough into the pan. If it’s too hard, it might have been overbaked or too much flour was used. Measure your flour correctly (spoon and level method is best) and bake just until the edges are lightly golden. Chilling the dough briefly before pressing it into the pan can sometimes help with manageability if it’s too soft, but for this recipe, cold butter cut into the flour usually yields the right texture.
