Step 1

Break up the Toblerone and put it in a microwave-proof jug or bowl along with the condensed milk.

Step 2

Put the bowl in the microwave on half power for 30 second bursts, until the chocolate starts to melt. Give it a good stir each time. Do not boil, as this will spoil the texture.

Step 3

Prepare the mould to set the fudge in. Brush a flexible takeaway tray or (6" x 4") silicon mould with oil or line a rigid pan with parchment.

Step 4

When the Toblerone has nearly all melted, give it all a good stir until smooth. The warmth of the mixture will melt the rest of the chocolate.

Step 5

Pour the melted Toblerone mixture into the prepared mould. Smooth the surface. Allow to cool, and then cover, or put the lid on. Place the tray in the fridge to set. This will take at least a couple of hours.

Step 6

Turn the fudge out of the mould and cut into squares. Store in an airtight container in a cool place.
