Detailed Directions and Instructions
Prepare the Shortbread Base
– Preheat your oven to 350°F (175°C). Line an 8-inch square baking tin with parchment paper.
– Cream the softened butter and sugar together until light and fluffy.
– Add the flour and salt, mixing until a crumbly dough forms.
– Press the dough evenly into the prepared tin, smoothing the top with the back of a spoon.
– Bake for 20–25 minutes or until lightly golden. Let it cool completely.
Make the Caramel Layer
– In a saucepan over medium heat, melt the butter and stir in the brown sugar, condensed milk, golden syrup, and salt.
– Bring it to a gentle boil, stirring constantly for about 10 minutes until the caramel thickens and turns a deep golden color.
– Pour the caramel over the cooled shortbread layer, spreading it evenly.
– Chill in the fridge for about an hour until set.
Add the Biscoff Topping
– Gently warm the Biscoff spread in the microwave for a few seconds to make it pourable.
– Pour it over the chilled caramel, smoothing it out with a spatula.
– Sprinkle the crushed Biscoff biscuits over the top for extra crunch and flavor.
– Chill again until set.
Slice and Serve
– Once fully set, use a sharp knife to slice the shortbread into squares. Wipe the knife clean between cuts for neat edges.
– Serve with coffee, tea, or as a luxurious dessert.

Cook Techniques
Creaming
Creaming is the process of beating together softened butter and sugar until the mixture is light and fluffy. This aerates the butter, helping to create a tender texture in baked goods.
Baking
Baking is the process of cooking food using dry heat in an oven. It is essential for developing flavors and textures in baked recipes like shortbread.
Caramelizing
Caramelizing involves cooking sugar until it melts and turns golden brown. In this recipe, the combination of butter, brown sugar, and condensed milk is heated to create a thick and rich caramel layer.
Chilling
Chilling is allowing the layered dessert to cool in the refrigerator, helping to set the caramel and Biscoff layers for easier slicing and a better texture.
Slicing
Slicing should be done with a sharp knife to ensure clean cuts. Wiping the knife between cuts prevents the layers from sticking and maintains neat edges.
