PISTACHIO CAKE

Steps:

• Preheat oven to 350°F. Butter a 13- by 9-inch metal cake pan, then line bottom with wax paper. Butter paper and dust pan with some flour, knocking out excess.
• Pulse pistachios in a food processor until finely ground (be careful not to overprocess into a paste). Add 1 cup flour, baking powder, cardamom, and salt and pulse once or twice to mix.
• Combine milk and vanilla in a measuring cup.
• Beat together butter and sugar in a large bowl with an electric mixer until pale and fluffy. Add eggs 1 at a time, beating well after each addition. Alternately add pistachio flour and milk in batches, beginning and ending with flour, and mix at low speed until just combined.
• Spread batter evenly in cake pan and bake in middle of oven until a tester comes out clean, about 20 minutes. Cool in pan on a rack 10 minutes, then run a thin knife around sides of cake and invert onto rack. Remove paper and reinvert cake onto a platter. Cut into squares and serve warm or at room temperature.
