2 sticks salted butter, at room temperature, plus more for the pan
1 3/4 cups all-purpose flour, plus more for the pan
3 large eggs, plus 1 egg yolk, at room temperature
1/4 cup plus 3 to 4 tablespoons heavy cream
2 1/4 teaspoons pure vanilla extract
1 1/4 cups organic cane sugar
3/4 cup confectioners' sugar
Quality ingredients make a big difference in pound cake. Try using premium butter — and if you can, use organic cane sugar. It gives the loaves a great crunchy top.
