Instructions

Step 1: Preheat & Prep

Preheat your oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan and set it aside.

Step 2: Mix the Dry Ingredients

In a medium bowl, whisk together the flour, baking powder, ground cinnamon, salt, and nutmeg.

Step 3: Cream the Wet Ingredients

In a large mixing bowl, beat the softened butter and granulated sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each. Stir in the vanilla extract.

Step 4: Combine Batter

Add the dry ingredients to the wet mixture in 3 parts, alternating with the buttermilk in 2 parts. Begin and end with dry ingredients. Mix until just combined.

Step 5: Make the Cinnamon Swirl

In a small bowl, mix together the brown sugar, ground cinnamon, and melted butter until combined.

Step 6: Layer & Swirl

Pour half of the batter into the prepared pan. Spoon half the cinnamon swirl mixture over the batter. Use a knife to gently swirl it through.
Repeat with the remaining batter and cinnamon mixture. Swirl again for a beautiful marbled effect.

Step 7: Top & Bake

Sprinkle the 1 tablespoon granulated sugar evenly on top for a crunchy finish.
Bake for 55–60 minutes, or until a toothpick inserted in the center comes out clean.

Step 8: Cool & Serve

Let the loaf cool in the pan for 10–15 minutes, then transfer to a wire rack to cool completely before slicing.

Notes

Want a glazed finish? Drizzle with a simple vanilla icing once cool.
Use sour cream instead of buttermilk for a richer texture.
This bread freezes beautifully! Wrap tightly and freeze for up to 2 months.
