We were looking for a different St. Patrick's Day dessert, and this turned out wonderfully! For those comfortable with US measurements, here's what I used in the cake: 1/2 cup unsalted butter, 1 cup packed brown sugar, 1 1/4 cups all purpose flour, 1 1/2 teaspoons baking powder, 1/2 teaspoon salt (latter three ingredients sifted together). For the icing, I used 1/3 cup of unsalted butter, 1 1/3 cups icing sugar, and a pinch of salt. I also omitted the honey, and added a teaspoon of Scotch. I baked this in a 6 cup bundt pan, at 350 for 25 min. Thanks for sharing a winner!
