1 tsp ghee (for greasing)

Cooking steps

Step 1:  Prep the tray
Lightly grease a large baking tray with ghee and set aside.

Step 2:  Combine milk and sugar
Pour the sweetened condensed milk into a medium saucepan over low heat.  Gradually add the brown sugar, 1 tablespoon at a time, stirring constantly until fully dissolved.

Step 3:  Thicken the base
Continue stirring gently over low heat to prevent burning until the mixture begins to thicken.

Step 4:  Flavour
Stir in the vanilla essence, followed by the butter.  Stir throughly to fully incorporate.

Step 5: Test for readiness
Keep stirring until the mixture pulls away cleanly from the sides of the pan  Remoe from heat and stir vigorously for another 2 minutes off the stove.

Step 6:  Pour and set
Quickly pour the hot mixture into the greased tray before it hardens.  Smooth it evenly with a spatula.

Step 7:  Cut and Store
Allow the toffee to cool completely to room temperature, then cut into squares and store in an airtight container.
