Cinnamon Bread

A brown sugar and cinnamon swirl runs through this tender quick bread like a ribbon of warmth. The batter goes in two layers with the cinnamon-sugar mixture sandwiched between and sprinkled on top, then a knife dragged through creates those beautiful marble swirls.

Sour milk (buttermilk or milk with a splash of vinegar) reacts with the baking powder to give the bread its rise and adds a subtle tang that balances all that sweetness. The crumb stays moist and soft, more like a coffee cake than a traditional bread.

The knife-swirl technique is the fun part. One pass through the layered batter pulls the cinnamon sugar into veins and pockets that caramelize slightly during the long bake, creating gooey streaks against the tender crumb.

Kitchen Tips

• Don’t overmix the batter after combining wet and dry. A few lumps are fine. Overmixed quick bread turns tough and dense.
• Drag the knife in a slow S-pattern through the batter. Too many passes mixes the swirl in completely and you lose the marbled look.
• Test doneness with a skewer in the center at 45 minutes. Some ovens need the full 60 minutes, but start checking early.

Variations

• Add a handful of chopped pecans or walnuts to the cinnamon-sugar mixture for a crunchier swirl.
• Drizzle a simple powdered sugar glaze over the cooled loaf for a bakery finish.
• Double the cinnamon-brown sugar mixture for a sweeter, more heavily swirled bread.
