Garlic Herb Swirl Bread

"Swirled Garlic Herb Bread. It's the prettiest, simpler to make than you'd think, and it's just SO GOOD. Light, doughy, and super soft (because homemade Brioche dough is the best), swirled with herb butter, hinted lightly with garlic. All the good things. Best served warm with a smear of butter. Nothing sounds better...at the moment at least. Oh, and the smell while this bakes? It. Is. Heavenly."
