Step 1

Melt together the butter and condensed milk in a large pot over a low heat on the stove top. You could use your microwave too.

Step 2

Take off the heat and add the coffee.

Step 3

Next add the walnuts (they do not need to be chopped), and crushed biscuits. Use your dough whisk to combine the ingredients.

Step 4

Line your 22cm square tin and press the mixture in.

Step 5

Use paper towels (triple thickness) to press down on the surface of the base mixture. This will create an even surface and soak up any excess butter.

Step 6

Place in the fridge to set. While it chills prepare the icing.

Step 7

Sift your icing sugar into a medium sized bowl

Step 8

Add your melted butter and strong coffee, and stir until you have a smooth consistency.

Step 9

If your icing is too runny add more icing sugar in small amounts until you get the consistency you want (tablespoon amounts at a time).

Step 10

Use a platte knife to spread the icing over your base.

Step 11

Add roughly chopped walnuts to the top for a more rustic look.

Step 12

Return to the fridge to until chilled and set.
