Description

Buttery Cinnamon Swirl Donut Loaf is a soft baked loaf inspired by classic cinnamon sugar donuts, featuring warm cinnamon spice, a buttery vanilla cake base, a sweet cinnamon swirl, and a crunchy sugar crust on top. It is perfect for breakfast, brunch, or dessert.


Ingredients

  • 1/2 teaspoon ground nutmeg
  • 1 cup granulated sugar
  • 1/2 cup unsalted butter, melted
  • 2 large eggs
  • 1 cup whole milk
  • 1 teaspoon vanilla extract
  • 1/3 cup granulated sugar (for swirl)

Instructions

  2. Whisk flour, baking powder, salt, cinnamon, and nutmeg in a bowl.
  3. In another bowl, mix sugar, melted butter, eggs, milk, and vanilla until smooth.
  4. Combine wet and dry ingredients until just mixed.
  5. Mix swirl sugar, cinnamon, and melted butter in a small bowl.
  6. Pour half the batter into pan, add half swirl, then repeat layers.
  7. Swirl gently with a knife.
  8. Bake 50–60 minutes until a toothpick comes out clean.

Notes

  • Do not overmix batter to keep loaf soft and tender.
  • Nutmeg gives classic donut flavor.
  • Cover loosely with foil if top browns too quickly.
  • Best texture when slightly warm.
  • Can be served plain or with glaze.
  • Swirl gently to avoid overmixing layers.
