Brazilian Jubilee Cookies were recommended by my neighbor who said her mom used to make them all the time when she was growing up. It appears they made an appearance in the 1952 Pillsbury Bake-Off, though did not take the top prize.
Using the full 2T of instant coffee granules gives them a distinct coffee flavor and a bitterness that's offset by the chocolate topping.
I used butter instead of shortening and topped half with milk chocolate and half with dark chocolate. I found it easier to melt the chocolate and spoon it on top rather than the method described in the recipe.
Oh, and I lightly toasted the Brazil nuts after chopping them.
