Preheat the oven to 350°F. Line a 1-pound loaf pan with parchment paper, letting it fold over the sides for easier removal.
In the bowl of a stand mixer fitted with the paddle attachment, cream the butter, cane sugar and vanilla extract. Add in the eggs and mix on low until combined. Scrape down the side of the bowl and mix again until combined.
Add the milk, cake flour and sea salt in that order, and mix on low until combined, scraping down the sides of the bowl as needed to ensure a smooth batter and everything is mixed.
Pour the cake batter into the loaf pan and spread evenly.
Bake for 1 hour 15 minutes or until a wooden pick inserted in center comes out clean. Allow to cool completely in the cake pan.
Sift powdered sugar on top.
Store in an airtight container for up to 7 days.

Notes
Tips
Always weight ingredients for the best results.
Depending on the loaf pan you use, you'll get a slightly different size. I used my Caraway loaf pan here as I think it browns much better on the sides. But, I used to use my USA Pan loaf pan when we made this at my bake shop and this gives you more clean edges and a more square loaf slice.
If using a good nonstick pan, you can skip the parchment paper, like I do when I use the Caraway loaf pan. But, if I'm using an aluminum loaf pan, I always line with parchment paper.
I like to bake this loaf cake at night so it has time to cool completely before removing and serving. I think pound cake is best when you let it rest for a bit for the flavor to fully develop!
High Altitude — Bake at 350°F for 1 hour, or until a wooden pick inserted in the center comes out clean.
