I created this recipe for my mother who loves Pistachios. Since the first slice was served I get requests for this cake all the time. Friends and family actually get mad when I don't bake one for a party or cook-out. The cake comes out extremely moist and the frosting is to die for. I use the frosting method for all frostings, by changing the pudding flavor (chocolate pudding for chocolate frosting etc…). I’ve always use instant pudding mix in this recipe, so I’m not sure how sugar-free or non-instant puddings will work. Have fun and enjoy, I hope it’s as big a hit for you as it is for me.
