Grease and flour a tube pan. Preheat oven to 325 degrees F
In a separate bowl whisk the cake flour, salt, and baking powder for 30 seconds to combine. Set aside for later.
Cream the butter with the paddle attachment in your mixer on medium speed until smooth. Gradually add the sugar and mix until lighten in color and fluffy 3 to 5 minutes.
Add the eggs one at a time, mixing after each until the yellow of the yolk blends in.
Add the whipping cream, lemon juice, lemon extract, and lemon zest to a measuring cup or bowl.
Add the flour mixture alternately with the whipping cream mixture. Begin and end with the dry ingredients. We do three additions of the flour mixture and two of the whipping cream mixture.
Pour or spoon the batter into a prepared tube pan.
Bake at 325 degrees for 60-65 minutes or until a toothpick comes out clean (or with just a few crumbs attached.) Baking times can vary and so peek in as it approaches the 1 hour mark. If the top of the cake begins to get too dark, cover loosely with a piece of aluminum foil.
This recipe makes approximately 8 cups of batter.
Allow to cool in the pan for about 10 minutes before turning out onto serving plate.
For the Easy Lemon Glaze
Combine sugar and lemon juice in a bowl and stir until smooth.
Drizzle over the pound cake. (I spooned mine into a piping bag with the tip snipped away for more control.) Sprinkle lemon zest over the top.
