Step 1: Prepare the Shortbread Base
The first layer mimics the buttery shortbread cookie found in a Twix bar, but without the need for baking.
- Crush the biscuits – Place 2 cups of digestive biscuits, graham crackers, or shortbread cookies in a food processor and pulse until they turn into fine crumbs. If you don’t have a food processor, place them in a ziplock bag and crush them with a rolling pin.
- Melt the butter – In a microwave-safe bowl, melt ½ cup of unsalted butter until fully liquid.
- Mix the base – In a large bowl, combine the crushed biscuits, melted butter, and 2 tablespoons of brown sugar. Stir well until the mixture has the texture of wet sand.
- Press into the pan – Line an 8×8-inch square baking dish with parchment paper. Firmly press the biscuit mixture into the bottom to form an even layer. Use the back of a spoon or a flat-bottomed glass to compact it.
- Chill – Place the pan in the refrigerator while you prepare the caramel layer.
Step 2: Make the Caramel Layer
This rich, chewy caramel layer is what gives No Bake Twix Squares their signature taste.
- Melt the butter and sugar – In a medium saucepan, add ½ cup unsalted butter and ½ cup light brown sugar. Cook over medium heat, stirring constantly, until the sugar dissolves.
- Add condensed milk and syrup – Pour in 1 can (14 oz) sweetened condensed milk and 2 tablespoons golden syrup or corn syrup. Stir well.
- Cook the caramel – Keep the mixture on medium heat, stirring constantly, until it thickens and turns a golden caramel color. This takes about 5–7 minutes.
- Test for doneness – Drop a small amount of caramel into a glass of ice water. If it forms a soft ball, it’s ready.
- Pour over the base – Remove the shortbread base from the fridge and pour the caramel evenly over it. Smooth it out with a spatula.
- Chill – Return the pan to the refrigerator and let the caramel set for at least 30 minutes.
Step 3: Prepare the Chocolate Topping
The final layer is a smooth, glossy chocolate topping that completes the Twix-inspired treat.
- Melt the chocolate – In a microwave-safe bowl, combine 1 ½ cups of chopped milk chocolate or chocolate chips with 1 teaspoon of coconut oil or vegetable oil (optional, for a smoother texture).
- Microwave in intervals – Heat in 30-second intervals, stirring after each one, until the chocolate is completely melted and smooth.
- Pour over the caramel layer – Remove the chilled caramel layer from the fridge and evenly spread the melted chocolate on top. Use an offset spatula to smooth it out.
- Chill again – Place the pan back in the fridge for at least 1 hour, or until the chocolate is fully set.
Step 4: Slice & Serve
Once the chocolate is firm, it’s time to cut and enjoy your homemade No Bake Twix Squares!
- Remove from the pan – Lift the parchment paper to take the entire dessert out of the pan.
- Score the chocolate – Let the dessert sit at room temperature for 5 minutes to prevent cracking. Use a sharp knife to score the chocolate layer before cutting.
- Cut into squares – Slice into 16 small squares or 9 larger bars, depending on your preference.
- Serve & enjoy!
