A rich and moist pistachio cake made more tender with pressure cooker baking, infused with almond and vanilla, and topped with velvety cream cheese frosting.
Preheat oven to 350°F. Grease and line three 8-inch cake pans with parchment paper.
Pulse pistachios in food processor until finely ground. Combine with cake flour, baking powder, soda, and salt.
In large bowl, beat butter and sugar on high for 2 minutes until fluffy. Add egg whites one by one, mixing well each time.
Stir in sour cream and extracts. Mix dry ingredients in three parts with mixer on low.
Divide batter into pans, smooth tops. Bake 28–32 min until tester comes out clean. Cool ten minutes in pans, then on wire rack.
Make frosting: beat cream cheese, butter, sugar, vanilla, and salt until smooth.
Frost cooled cake with frosting. Decorate with berries or crushed pistachios as desired.
Store leftovers in airtight container. Can freeze up to 3 months. Thaw overnight and bring to room temp before serving.
Notes
For best results, use room temperature ingredients and avoid overmixing. For an extra touch, add a sprinkle of chopped pistachios over the frosting before serving.
