What Is Twix Cookie Bars?
Twix cookie bars transform the famous chocolate candy into thick, shareable dessert bars. Instead of thin individual sticks, you get generous layers in an easy-to-slice pan.
The base is a simple shortbread that bakes up golden and sturdy enough to hold the toppings. A creamy caramel layer adds chewiness, while melted chocolate creates that signature snap when you bite in. The combination works beautifully because each layer complements the others in both flavor and texture.

Home bakers have created many versions over the years, and this one focuses on reliable results with straightforward methods that work in any kitchen.
Ingredients You’ll Need
Shortbread Base
- 1 cup (226g) unsalted butter, softened: Creates tender, rich shortbread.
- ½ cup (100g) granulated sugar: Sweetens without making it too soft.
- 1 teaspoon vanilla extract: Adds warm depth.
- 2 cups (250g) all-purpose flour: Forms the structure.
- ¼ teaspoon salt: Balances the sweetness.
Caramel Layer
- 1 can (14 oz / 397g) sweetened condensed milk: Provides creamy caramel base.
- ½ cup (113g) unsalted butter: Adds richness and smoothness.
- ½ cup (100g) brown sugar: Deepens caramel flavor.
- 3 tablespoons light corn syrup: Prevents crystallization for smooth texture.
- 1 teaspoon vanilla extract: Enhances flavor.
- ½ teaspoon sea salt: Cuts sweetness and creates salted caramel taste.
Chocolate Topping
- 2 cups (340g) semi-sweet chocolate chips: Gives classic Twix flavor.
- 2 tablespoons coconut oil or shortening: Creates smooth, snappy finish when set.
How to Make Twix Cookie Bars
Step 1: Prepare the Shortbread Base Preheat oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving overhang on sides.
Beat softened butter and granulated sugar until light and fluffy, about 2 minutes. Mix in vanilla. Add flour and salt, mixing until crumbly dough forms. Press evenly into prepared pan.
Bake 20-25 minutes until edges turn golden. Cool completely on a wire rack.
Step 2: Make the Caramel Layer In a medium saucepan over medium heat, combine condensed milk, butter, brown sugar, and corn syrup. Stir constantly until butter melts and mixture thickens, about 8-10 minutes. It should reach a gentle boil and turn light golden. Remove from heat, stir in vanilla and sea salt.
Pour warm caramel over cooled shortbread. Spread evenly with a spatula. Chill in refrigerator for 30 minutes until caramel firms up.
Step 3: Add Chocolate Topping Melt chocolate chips with coconut oil in microwave in 20-second intervals, stirring between each until smooth.
Pour over chilled caramel layer and spread evenly. Tap pan gently to remove air bubbles. Refrigerate for at least 1 hour until chocolate sets completely.
Step 4: Slice and Serve Use parchment overhang to lift bars from pan. Place on cutting board and slice into 24 rectangles using a sharp knife wiped clean between cuts for neat edges.
The Simple Cooking Science Behind This Recipe
The shortbread works because creaming butter and sugar incorporates air while keeping the dough tender. Baking at moderate temperature prevents spreading and creates crisp edges with a soft center.
Caramel reaches perfect consistency through gentle cooking. Constant stirring and corn syrup prevent sugar crystals, resulting in smooth, chewy texture instead of grainy or rock-hard caramel.
Chilling between layers is crucial. It keeps each layer distinct so the caramel stays soft while chocolate sets with a clean snap.
Expert Tips for Best Results
- Bring butter to room temperature for easier creaming and better texture.
- Press shortbread firmly and evenly so it doesn’t crumble when slicing.
- Stir caramel constantly to avoid scorching on the bottom.
- Use good quality chocolate chips for best melting and flavor.
- Chill thoroughly before cutting to prevent layers from sliding.
- Wipe knife with hot water between cuts for professional-looking bars.
- Cut while chocolate is still slightly firm but not rock hard.
Easy Variations
- Peanut Butter Twix Bars: Swirl ⅓ cup peanut butter into caramel before pouring.
- Dark Chocolate Version: Use dark chocolate chips for less sweetness.
- Sea Salt Flaky Finish: Sprinkle flaky sea salt on chocolate before it sets.
- Cookie Dough Twist: Add ½ cup mini chocolate chips to shortbread dough.
- Mini Bars: Bake in a smaller pan and cut into bite-size pieces for parties.
- Gluten-Free: Swap all-purpose flour with 1:1 gluten-free baking flour.
What to Serve With Twix Cookie Bars
Serve these bars with cold milk, hot coffee, or vanilla ice cream. They pair beautifully with fresh strawberries or raspberries for balance.
For parties, arrange on a platter with other cookies and brownies. Great for holiday cookie boxes, school bake sales, or movie night treats. Add them to dessert tables alongside cheesecake or fruit salad.
How to Store and Reheat
Store Twix cookie bars in an airtight container in the refrigerator for up to 10 days. Keep layers between parchment paper to prevent sticking.
They can be frozen for up to 2 months. Wrap individual bars tightly in plastic wrap then foil. Thaw overnight in the refrigerator. Freezing works well but caramel may become slightly firmer.
Serve cold or let sit at room temperature for 10-15 minutes before eating. Do not microwave as chocolate can bloom and caramel may separate.
Common Mistakes to Avoid
- Skipping parchment paper: Makes removal and clean slicing nearly impossible.
- Rushing chilling time: Warm layers will blend together instead of staying distinct.
- Overcooking caramel: Results in hard, chewy texture instead of soft and gooey.
- Using cold butter: Creates crumbly shortbread that falls apart easily.
- Poor quality chocolate: Leads to grainy or dull topping that doesn’t set nicely.
- Cutting too soon: Chocolate cracks messily and layers slide apart.
Frequently Asked Questions
Can I use store-bought caramel sauce? Homemade caramel from condensed milk gives best texture and flavor, but high-quality thick caramel sauce works in a pinch. Avoid thin ice cream syrups.
How do I make these less sweet? Use dark chocolate and add extra sea salt. You can also reduce brown sugar in caramel by 2 tablespoons.
Can I make these ahead for a party? Yes! Make up to 5 days ahead and store in the fridge. They actually taste better after a day as flavors meld.
Why did my chocolate crack when cutting? Chocolate was too cold. Let bars sit 5-10 minutes at room temperature before slicing.
Are these gluten-free? Only if you use gluten-free flour blend. Regular version contains wheat flour.
Can I use a different pan size? Yes, but adjust baking time. A 8×8 pan makes thicker bars and may need 5 extra minutes for shortbread.
