Mix coffe with water, stir until dissolved. Bake per package directions.
Glaze:
Heat milk and butter. Add to sifted confectioners sugar in bowl, stir until smooth. Add lemon juice and rind. Spread over cake, letting it run down sides.
Note: I use juice and grated rind of 1 lemon as my family prefers the 'lemony' taste.
Easy make-ahead dessert.
