Ingredients Method Notes

Ingredients
  

  • The Bread: 2 cups all-purpose flour 1 cup finely grated carrots, ½ cup sour cream, ⅓ cup buttermilk, ½ cup granulated sugar, ½ cup light brown sugar, ½ cup neutral oil (canola), 2 large eggs, 1 tsp vanilla, 1 tsp baking soda, ½ tsp baking powder, 1 ½ tsp cinnamon, ¼ tsp each of nutmeg and ginger, ½ tsp kosher salt.
  • Cinnamon Sugar Swirl: ½ cup light brown sugar 2 tsp cinnamon, 3 tbsp melted butter, 2 tbsp flour, pinch of salt.
  • Brown Butter Icing: 5 oz cream cheese softened, 4 tbsp unsalted butter, ⅓–½ cup powdered sugar, 1 tsp vanilla bean paste.

Method
 

  1. Prep: Preheat oven to 325°F (163°C). Grease/line a loaf pan with parchment paper.
  2. Swirl Paste: In a small bowl, mix all "Cinnamon Sugar Swirl" ingredients into a paste. Set aside.
  3. Wet Batter: In a large bowl, mix oil and sugars. Beat in eggs one at a time, then vanilla. In a separate cup, stir buttermilk and sour cream together.
  4. Combine: Whisk dry ingredients in a separate bowl. Fold dry ingredients into the oil mixture while slowly pouring in the buttermilk mixture. Fold in carrots. Do not overmix!
  5. Layer: Pour half the batter into the pan. Spoon half the cinnamon paste on top and swirl with a knife. Repeat with the remaining batter and paste.
  6. Bake: Bake for 50–60 minutes (until a toothpick has just a few crumbs). Cool in pan for 20 mins, then on a rack for 30 mins.
  7. Brown the Butter: Melt frosting butter in a pan until foamy and golden brown bits form. Pour into a bowl and cool for 15 mins.
  8. Frost: Beat cream cheese into the brown butter. Add powdered sugar and vanilla bean paste; whip until smooth. Spread over the fully cooled loaf.

Notes

  • Storage: If iced, store in an airtight container in the fridge for 2–3 days. If uniced, it can stay at room temperature for the same duration.
  • Brown Butter Tip: Don't leave the brown bits in the pan! Those "specks" hold all the toasted flavor for your icing.
  • Texture: Grate your carrots finely (using the small holes of a box grater) so they melt into the bread rather than leaving long, crunchy strands.
