I cannot take credit for the recipe or the photograph. This was sent to me today by a friend today in an e mail. I thought it was appropriate for St. Patrick's Day and wanted to share it. I haven't made it yet, so can't even say it's tried and true. I will make it next week for our St. Pat's Day dinner. If you try it, I would appreciate any feed back. Thanks!
Preheat the oven to 375º F. Butter three 8-inch round cake pans, line with parchment; butter the parchment and set aside. Whisk the flour, cocoa powder, baking powder, baking soda and salt in a medium bowl; set aside. Whisk the buttermilk, food coloring and vanilla in a spouted measuring cup; set aside.
Beat the granulated sugar and butter in a stand mixer (or a large bowl if using a hand mixer) on medium speed until very light in color and fluffy, about 5 minutes, scraping down the sides of the bowl as needed. With the mixer still running, slowly add the eggs and beat until fully incorporated.
Reduce the mixer speed to the lowest speed; with it running, add one-third of the flour mixture, then ½ of the buttermilk mixture, then ½ of the remaining flour mixture, then the remaining buttermilk mixture, then the remaining flour mixture. Scrape down the sides and beat until well mixed.
Divide the batter evenly among the three prepared pans. Bake until slightly puffed and a toothpick comes out clean when inserted in the center, 20 to 25 minutes. Let cool 15 minutes in the pan, then turn out to a wire rack and cool completely.
Frost with prepared cream cheese or butter cream frosting. Decorate with green candies and/or sanding sugar, optional.
