Preheat your oven to 325℉.
Grease your bundt cake pan with shortening generously. You will also add granulated sugar right before adding the batter.
In a large bowl, combine the sugar and butter using a hand mixer. You can also use a stand mixer if need be.
Add eggs one each at a time and mix, scraping the sides of the bowl down to incorporate everything.
In a medium bowl, whisk the dry ingredients together.
Add the dry ingredients to the large bowl of wet ingredients.
Add the lemon zest, lemon juice, and buttermilk (*see note below if you need to make your own).
Beat on low speed until fully combined.
Generously sugar the shortening lined bundt pan.
Pour wet batter into the bundt pan.
Bake for 55-60 minutes. See notes if you are making two loaves.
Test center of the cake with a toothpick to ensure it is fully baked.
Allow cake to fully cool for one hour before attempting to remove it.
