Preheat oven to 350°F (175°C). Grease an 8-inch round cake pan. Next, blend the shelled pistachios until they are fine like flour.
In a large bowl, beat the softened butter and sugar for 3 to 4 minutes until the mixture is pale and fluffy
Add the eggs, mixing well. Mix in the pistachio essence.
Add the pistachio powder, baking powder, and baking soda to another bowl. Mix to remove any lumps.
Add them to the wet mixture in a large bowl and mix well until just combined.
Pour the batter evenly into the prepared pan. Bake for 25-30 minutes until a toothpick inserted in the center comes out clean or with a few tender crumbs. Let the cakes cool completely before frosting.
(Optional): If frosting, beat the softened cream cheese and butter until beautifully creamy. Add the powdered sugar, vanilla extract, and a pinch of salt. Beat until smooth.
Frost the layers, sprinkle the top with the chopped pistachios
