Heat oven to 425 F. Grease a 9x5 inch loaf pan, then line with parchment so it overhangs for easy lifting.
Beat cream cheese and sugar with a mixer on medium until smooth with no lumps.
Beat in eggs one at a time, scraping the bowl after each addition.
Mix in heavy cream, vanilla, and salt just until combined. Do not overmix.
Pour batter into the lined pan. Tap the pan once to release big air bubbles.
Bake 28 to 35 minutes until the top is deeply browned and the center still jiggles like soft gel.
Cool the pan on a rack until just warm, then lift out using the parchment and let cool to room temperature.
Chill uncovered until cold, at least 4 hours. Slice with a warm knife and wipe between cuts.
