Instructions
Preparing the shortbread base
The first step to making stable caramel nut fudge bars is creating a solid base. This base supports the thick caramel layer and prevents the dessert from becoming too sticky or soft. Begin by preheating the oven to 180°C (350°F). In a mixing bowl, combine flour, sugar, and a pinch of salt. Add the cold butter cubes and rub them into the dry ingredients using your fingertips or a pastry cutter. You should end up with a crumbly mixture resembling coarse sand. Add the vanilla extract and gently press the dough into a parchment-lined baking dish.
Smooth the dough with the back of a spoon to ensure even thickness, which helps the bars bake uniformly. Bake the base for about 18–20 minutes, or until lightly golden. Remove from the oven and set aside to cool slightly while you prepare the caramel filling. The base should not be fully browned; a soft golden shade is perfect because it will continue firming as it cools.
Making the caramel nut filling
Caramel can be intimidating for many home bakers, but this recipe uses a foolproof method. In a large saucepan over medium heat, melt the butter completely. Add the brown sugar, condensed milk, heavy cream, and salt. Stir continuously to prevent sticking. As the mixture warms, it will start to bubble. Continue stirring for 8–10 minutes until the caramel thickens and turns a deeper golden color. You are aiming for a soft fudge texture rather than a liquid sauce.
When the caramel reaches the right consistency, remove the pan from the heat and stir in the vanilla extract followed by the roasted nuts. Folding the nuts in off the heat prevents them from softening too much. Immediately pour the caramel nut mixture over the baked shortbread base. Spread it gently using a silicone spatula to ensure an even layer that covers every corner of the dish.
Preparing the glossy top layer
This step is optional but highly recommended. The thin top caramel layer adds a glossy surface that makes the bars look professional and bakery-quality. In a small saucepan, melt the butter and add condensed milk and brown sugar. Cook over medium heat for 3–4 minutes just until the mixture thickens slightly. Pour it evenly over the nut-filled caramel layer.
Cooling and cutting the bars
Patience is crucial at this stage. Allow the dessert to cool at room temperature for at least 2 hours. For best results, refrigerate the tray for another hour before cutting. When the caramel fully sets, use a sharp knife and cut the bars into neat squares. Clean the knife between each cut for smooth edges similar to what you see in the image.
