Martha Stewart on Instagram: "Highlight the emerald color of St. Patrick’s Day with our pistachio cannoli cake that's ideal for the passionate baker. The cake's green hue come from the nuts baked into its moist layers and those placed on the outside. A mouthwatering cannoli-style filling with ricotta, chopped chocolate, and candied orange zest sits between the layers, making this cake a true showstopper.
