This is truly a “special occasion” cake. It’s rich, but St. Patrick’s Day only comes once a year, right? While this cake is stunning all white, we’ve given it that Irish touch of green using spinach as a natural food colorant. Yes, spinach … but you cannot taste it at ALL in the cake. Of course, you can always omit it and use food coloring as we did with the coconut, if you prefer. This is a moist, dense cake which lends itself well to stacking and frosting. We used small cake pans, about 6″ to create this cake, but you could certainly use two of the traditional 8″ pans.
