Beat the butter with the egg yolks until creamy.
Add the flour and the milk and knead well. Divide the dough into 5 pieces
and roll these into 9 inch circles. Bake the circles about 10 minutes
at 175 degrees Celsius and allow
them to cool down. In the meantime, bring a large pan of water to the
boil and put the unopened can of condensed milk in the water. Boil for
three hours (the milk will caramelize). Open the can. Sprinkle 1 cookie
layer with brandy, add some of the caramelized milk, sprinkle with nuts.
Put a cookie layer on top. Continue until you can close the stack with
the last cookie layer.
This recipe is actually called "torta de mil hojas" (cake of 1,000 sheets)
but I did not have time to make 1,000 layers.
Put all ingredients
together and mix them well. Pour the batter into a greased cake mold
and bake the cake 50 minutes at 175 degrees
Celsius. Allow it to cool down and
dust with icing sugar.
