Preheat oven to 350 degrees Fahrenheit.
Grease a 9-inch springform pan using butter. Dust inside of pan with powdered sugar.
With a mixer, cream together the butter and sugar until well combined. Add the ricotta cheese and blend until light and fluffy (about 4-5 minutes).
Mix in eggs one at a time. Add the vanilla, lemon zest, and lemon juice. Mix to combine.
In the same bowl, stir in the baking soda and salt. Add in the flour until just combined.
Pour the batter into a the prepared springform pan. Bake for 45-55 minutes or until the cake is set, the top and sides are lightly browned, and a toothpick inserted into the middle of the cake comes out clean.
Let it cool in the pan for 15 minutes. Then remove the cake from the pan and finish cooling on a wire rack.
Dust with powdered sugar before serving (optional). Alternatively, make a glaze by mixing 1-1/4 cups of powdered sugar, 1 teaspoon of lemon zest and 2-3 Tablespoons of lemon juice to achieve the desired consistency.
