Twix Cookie Bars

I still remember the first time I tried making Twix cookie bars at home and how excited I was to recreate that familiar candy bar flavor in my own kitchen using simple pantry ingredients and lots of love. I had this idea one rainy afternoon when I was craving something sweet and nostalgic and rather than reaching for a store-bought snack I decided to bake a batch from scratch. The moment I cut into that soft shortbread crust and saw the golden caramel and glossy chocolate layer on top I knew I had stumbled onto something special.

Since then these Twix cookie bars have become a regular treat in my house and not just for holidays or parties but for quiet evenings and unexpected guests too. Every time I make them I try to tweak something just a little whether it’s the thickness of the chocolate or the saltiness of the caramel and it always brings me joy to share the results. If you’re a fan of sweet layered desserts and love the classic candy bar as much as I do you’re going to adore this homemade version.

Ingredients

Here’s what I use for this recipe. You can always make substitutions if you prefer!

• All-purpose flour – The base of the shortbread and gives it a tender crumb.
• Butter – Adds richness and creates that classic melt-in-your-mouth texture.
• Granulated sugar – Sweetens the shortbread and balances the caramel.
• Salt – Enhances all the flavors and keeps the bars from tasting too sweet.
• Sweetened condensed milk – The core of the luscious homemade caramel layer.
• Brown sugar – Gives the caramel a deep, toffee-like flavor.
• Corn syrup – Helps prevent the caramel from crystallizing and keeps it smooth.
• Milk chocolate chips – For that iconic Twix chocolate coating.
• Heavy cream – Makes the melted chocolate smooth and glossy.

Tools You’ll Need

• 9×13-inch baking pan – This is the perfect size for thick, even bars.
• Parchment paper – Helps lift the bars out easily without sticking.
• Medium saucepan – Essential for making smooth, golden caramel.
• Mixing bowls – Great for preparing the crust and melting chocolate separately.
• Rubber spatula – I use this to spread each layer evenly.
• Whisk – Useful when making caramel to ensure a silky texture.
• Sharp knife – Needed for cutting clean slices once the bars are chilled.

Instructions

Step 1: Preheat the Oven

I start by preheating my oven to 350°F and lining a 9×13-inch baking pan with parchment paper for easy removal later.

Step 2: Make the Shortbread Crust

In a mixing bowl I cream together softened butter sugar and a pinch of salt until smooth and fluffy. Then I gradually mix in the flour until a crumbly dough forms.

Step 3: Press and Bake

I press the dough evenly into the bottom of the prepared pan using the back of a measuring cup to smooth it out. Then I bake it for 18 to 20 minutes until it’s just lightly golden on the edges.

Step 4: Prepare the Caramel

While the crust is cooling I move on to the caramel. In a medium saucepan over medium heat I combine sweetened condensed milk brown sugar corn syrup and butter whisking constantly. Once it comes to a bubble I reduce the heat and continue stirring for 6 to 8 minutes until it thickens and darkens slightly.

Step 5: Layer the Caramel

I pour the hot caramel over the cooled shortbread base and use a spatula to spread it evenly. Then I let it set for about 20 to 30 minutes at room temperature.

Step 6: Melt the Chocolate

In a heatproof bowl I melt the milk chocolate chips with heavy cream either in the microwave in short bursts or using a double boiler. I stir until smooth and silky.

Step 7: Top with Chocolate

I pour the melted chocolate over the caramel layer and gently spread it with a spatula to cover the entire surface.

Step 8: Chill and Slice

Finally I refrigerate the pan for at least 2 hours or until everything is firm. Once set I lift the bars out with the parchment paper and cut them into squares using a sharp knife.

Tips

If you want to make the caramel more salted I suggest sprinkling a bit of flaky sea salt over the top before adding the chocolate layer. I’ve also tried using dark chocolate instead of milk for a richer twist and it pairs beautifully with the sweet caramel. For a cleaner cut I recommend wiping the knife between slices and letting the bars sit at room temperature for a few minutes before slicing.

Ways to Serve

These Twix cookie bars are incredibly versatile. I often serve them chilled from the fridge for that crisp candy bar like bite but they’re just as delightful at room temperature with a softer texture. They pair wonderfully with coffee or milk and make the perfect addition to dessert platters for parties or potlucks. Sometimes I even wrap a few in parchment and pack them in lunchboxes or picnic baskets for a sweet surprise. You can also crumble them over ice cream for an indulgent sundae topping!

Frequently Asked Questions
