To make this coffee dessert recipe, firstly, in a small bowl, combine ½ cup milk with cornflour and whisk well to form a smooth slurry without lumps. Set aside.
Heat sugar in a saucepan over medium flame, spreading it evenly. Allow it to caramelize until golden amber in color, gently swirling the pan as needed until fully melted.
Add warm milk to the caramel. The mixture may seize initially, but keep stirring on low heat until smooth and fully combined.
Stir in coffee powder, then pour in the cornflour slurry, whisking continuously until the mixture thickens.
Remove from heat and transfer the mixture into a lightly greased mould.
Refrigerate the coffee caramel custard for 2–3 hours or until set.
Once set, carefully demould, cut into cubes and dust with cocoa powder,
Serve No Bake Eggless Coffee Caramel Bites chilled.
