Coffee Walnut Cookies

I think these are one of the first cookies i had made, back when i was a teenager and had started venturing into the world of baking, which at that time mostly consisted of pilsburry cake mixes.
what i like about the recipe is that, unlike most coffee recipes, the coffee flavor doesn't jump at you on the first bite, rather it has a very subtle coffee flavor.
this recipe is from my mom's huge box file which has like more than a hundred recipes, sometimes just to leaf through that file gives more ideas than surfing the net for recipes.

Ingredients:

150 g flour (or 50/50 with whole wheat flour)

80 g butter, softened

75 g powdered sugar

1 tsp coffee

50 g walnuts, crushed

1 – 2 tsp milk

Method:

Cream butter and sugar, until light and fluffy. Add the flour, coffee. Stir in the walnuts Mix till it forms into firm dough. Add a little milk if too dry.

Roll on a dusted surface, and cut into desired shapes.

Bake at 160°C for 10 – 15 minutes. Cool on a wire rack.
