This Orange and Pistachio Cake is a delightful dessert that combines the refreshing citrus flavor of oranges with the nutty crunch of pistachios. The cake is moist and tender, with a subtle hint of orange zest in every bite. The pistachios add a delightful texture and a pop of green color to the cake. It's perfect for any occasion and can be enjoyed on its own or with a dollop of whipped cream or a scoop of vanilla ice cream.
