Why This Recipe Works
Copycat Twix Bars Recipe With Crunchy Cookie and Caramel Layers - Easy, Homemade Treat
Ingredients
- For the shortbread base:
- 1 cup (2 sticks/226 g) unsalted butter, softened
- 1/2 cup (100 g) granulated sugar
- 1/4 cup (30 g) powdered sugar
- 2 cups (240 g) all-purpose flour
- 1/2 teaspoon fine salt
- 1 teaspoon vanilla extract
- For the caramel layer:
- 1/2 cup (1 stick/113 g) unsalted butter
- 1/2 cup (110 g) packed light brown sugar
- 1 can (14 oz/397 g) sweetened condensed milk
- 1/4 cup (60 ml) light corn syrup or golden syrup
- 1/2 teaspoon fine salt
- 1 teaspoon vanilla extract
- For the chocolate topping:
- 12 oz (340 g) milk chocolate chips or chopped milk chocolate
- 1 tablespoon neutral oil (vegetable or coconut) for smoothness
- Flaky sea salt (optional, for garnish)
- Tools:
- 9x13-inch (23x33 cm) baking pan
- Parchment paper
- Medium saucepan and heatproof spatula
- Microwave-safe bowl or double boiler
- Sharp knife
Instructions
- Prep the pan: Line a 9x13-inch baking pan with parchment, leaving overhang on two sides for easy lifting. Lightly grease the parchment.
- Make the shortbread dough: Beat softened butter with granulated and powdered sugars until smooth and creamy, about 1–2 minutes. Mix in vanilla and salt. Add flour and mix just until a soft dough forms.
- Press and dock: Press dough evenly into the lined pan. Use the bottom of a measuring cup to level it. Prick all over with a fork to prevent puffing.
- Bake the base: Bake at 325°F (165°C) for 20–25 minutes, until edges are lightly golden and the center looks set. Cool in the pan on a rack while you make the caramel.
- Cook the caramel: In a medium saucepan, combine butter, brown sugar, condensed milk, syrup, and salt. Cook over medium heat, stirring constantly, until it comes to a gentle bubble. Reduce heat to medium-low and cook 5–7 more minutes, stirring nonstop, until thickened and slightly darkened. It should coat the spatula and leave trails.
- Add vanilla and pour: Remove from heat, stir in vanilla, and immediately pour the caramel over the cooled shortbread. Tilt the pan and smooth the surface quickly.
- Set the caramel: Let the caramel cool at room temperature 20–30 minutes, then chill 20 more minutes until firm to the touch but not rock hard. This helps the chocolate set cleanly.
- Melt the chocolate: In a microwave-safe bowl, heat chocolate with oil in 20–30 second bursts, stirring between each, until smooth. Or melt over a double boiler, keeping water at a simmer and steam away from the bowl.
- Add the chocolate layer: Pour melted chocolate over the caramel. Spread evenly with an offset spatula. Tap the pan gently on the counter to pop any bubbles. Sprinkle flaky salt if using.
- Set and slice: Let the chocolate set at room temp until just firm, about 45–60 minutes, or chill 15–20 minutes. Use the parchment to lift the slab out. For clean slices, warm a sharp knife under hot water, wipe dry, and cut into bars or fingers.
The shortbread base uses a higher ratio of butter to flour for a crisp, yet tender crunch—just like the iconic cookie in Twix. The caramel is made with sweetened condensed milk, which speeds things up and gives a rich, chewy texture without needing a candy thermometer.
A thin layer of chocolate on top finishes everything off with snap and shine. The layers are balanced, so no single bite is too sweet, and each part holds together when sliced.

How to Store
- Room temperature: Keep bars in an airtight container for up to 3 days. Cool, dry conditions are best.
- Refrigerator: Store up to 2 weeks. Let bars sit out 10–15 minutes before serving so the caramel softens slightly.
- Freezer: Freeze sliced bars, layered with parchment, for up to 2 months.
Thaw in the fridge overnight, then bring to room temp.
- Avoid heat: Warm rooms can soften the caramel and make the chocolate bloom. Keep out of direct sun.
Benefits of This Recipe
- Fast caramel without a thermometer: Sweetened condensed milk gives a foolproof, chewy caramel in minutes.
- Balanced sweetness: The buttery shortbread offsets the caramel and chocolate, so each bite tastes like the real thing—without overload.
- Flexible format: Make bars, fingers, or bite-size squares. Great for parties, bake sales, or gifting.
- Make-ahead friendly: Layers set well and hold up in storage, so you can prep ahead.
- Customizable: Swap chocolates, add a pinch of espresso, or top with sea salt or chopped nuts.
What Not to Do
- Don’t rush the caramel: High heat can scorch it and turn it grainy.
Keep the heat moderate and stir constantly.
- Don’t pour chocolate on hot caramel: If the caramel is too warm, the chocolate can separate or streak. Let it set until firm to the touch.
- Don’t overbake the shortbread: Dark edges make the base hard. Pull it when lightly golden.
- Don’t skip parchment: Lifting the slab out of the pan makes clean slicing much easier.
- Don’t cut when the chocolate is ice-cold: It will shatter.
Slice when just set, using a warm knife.
Alternatives
- Chocolate type: Use semisweet or dark chocolate for less sweetness, or swirl milk and dark together.
- Caramel shortcut: In a pinch, use soft caramel candies melted with a splash of cream. Texture will be slightly firmer.
- Gluten-free: Substitute a high-quality 1:1 gluten-free flour blend for the shortbread. Add 1 tablespoon cornstarch for extra crispness.
- Nutty twist: Stir 1/2 cup finely chopped toasted almonds or hazelnuts into the caramel layer, or sprinkle on top of the chocolate.
- Mini bars: Use an 8×8-inch pan for thicker layers and cut into bite-size squares for rich, small treats.
- Salted caramel: Increase salt in the caramel to 3/4 teaspoon and finish with flaky sea salt on top.
FAQ
How do I know the caramel is thick enough?
It should visibly thicken, darken slightly, and leave a clear trail when you drag a spatula across the bottom of the pan.
A small spoonful dropped on a cool plate should hold its shape and feel chewy after a minute.
Can I use store-bought shortbread?
Yes. Line the pan with a tight layer of store-bought shortbread cookies, then proceed with the caramel and chocolate. The texture will be slightly different, but it works well in a pinch.
Why did my chocolate bloom or look streaky?
Chocolate can bloom if it warms and cools unevenly or if moisture gets in.
Make sure the caramel is cool, melt chocolate gently, and avoid refrigerating for long periods. A tablespoon of oil helps keep it glossy.
My caramel turned grainy. What happened?
Graininess often comes from overheating or not stirring constantly.
Next time, lower the heat and keep the mixture moving. If it separates, whisk vigorously off heat to bring it back together.
How can I cut clean slices?
Wait until the chocolate is just set, not rock hard. Use a long, sharp knife warmed under hot water and wiped dry.
Press straight down rather than sawing, and clean the blade between cuts.
Can I make this without corn syrup?
Yes. Golden syrup or honey works. Honey adds flavor, so use a light variety.
The syrup helps prevent crystallization and keeps the caramel smooth.
What if I only have salted butter?
Use it and reduce added salt by half in both the shortbread and caramel. Taste as you go and adjust at the end if needed.
Do I need a candy thermometer?
No. This recipe relies on visual cues and texture.
Stir consistently, keep the heat moderate, and watch for thickening and color change.
How do I get the classic Twix shape?
Cut the slab into long, narrow fingers once set. For extra authenticity, you can chill the fingers, then dip each one fully in melted chocolate instead of spreading it on top.
Can I double the recipe?
Yes. Use two 9×13 pans, or a rimmed half-sheet pan for thinner bars.
Watch baking and setting times, as thin layers set faster.
