Preheat the oven to 350° Chop, zest, mash and combine everything above, in a medium glass bowl. In a larger bowl, whisk together the following dry ingredients:
Pour the bowl of well combined wet ingredients into the flour bowl. Working quickly with a big silicone spatula, fold and combine these into a heavy batter. Today I transferred this to a buttered and sugared 8"x12"x2" glass baking pan to make a snack-coffee cake. This would have also made wonderful muffins! Bake the cake for 50-60 minutes. If making muffins, cut the baking time way down, start with 20 minutes then do the toothpick test. Let the cake cool an hour before cutting.

Mix these together until smooth in a small bowl. Pour and spread over the top.
Have fun with your creative combinations. . .Lin
