One of the most famous and delicious cake from Italy!

1 1/2 c cake flour – 2 1/2 tsp baking powder
1 tsp kosher salt – 3/4 c unsalted butter, softened
1 1/2 c fresh whole-milk ricotta
1 1/2 c granulated sugar – 2 medium eggs – 1 tsp pure vanilla extract
Preheat oven to 350°F (177°C) and place rack in center. Grease and flour 9-inch loaf pan. In medium bowl, sift together flour, baking powder, and salt and set aside.

In a separate bowl, cream together butter, ricotta, and sugar until smooth and light. Beat in eggs one at a time, scraping sides of bowl after each addition.
If you have a vanilla bean (I didn’t), split it lengthwise and scrape out the seeds with the blunt side of a small knife, then beat them into the batter along with the vanilla extract. I just used another teaspoon of vanilla extract.

On low speed, beat in dry ingredients to combine them, scrape down sides of the bowl, and beat the batter for 30 seconds on medium. Pour the batter into the prepared pan and smooth top with a spatula.
Tap pan on counter a few times to remove air pockets. Put cake in oven and let bake for 15 minutes, then turn 180 degrees to ensure even browning.

Lower the temperature to 160°C and let bake until cake springs back when lightly touched, the sides of the cake have pulled away from the sides of the pan, and a cake tester inserted in center comes out clean, about 25 minutes more.
