  • 200 grams brown sugar (about 1 cup)
  • 5 grams baking soda (about 1 teaspoon)
  • 5 grams baking powder (about 1 teaspoon)
  • 7 grams salt (about 1 teaspoon)
  • 4 grams ground cinnamon (about 1 1/2 teaspoons)
  • 1 gram ground ginger (about 1/2 teaspoon)
  • 1 gram ground nutmeg (about 1/2 teaspoon)
  • 165 grams carrots, shredded (about 1 1/2 cups)
  • 100 grams chopped nuts or dried fruit (optional, about 3/4 cup)

Cream Cheese Topping

  • 56 grams unsalted butter, softened (about 4 tablespoons)
  • 28 grams cream cheese, softened (about 1 ounce)
  • 120 grams powdered sugar (about 1 cup)
  • 15 grams heavy cream (about 1-2 tablespoons, as needed)
  • 2 grams vanilla extract (about 1/2 teaspoon)
  • 1 pinch salt

Method

Preparation

  • Preheat your oven to 350°F (175°C) and grease a loaf pan.
  • In a large bowl, mix together the sourdough discard, melted coconut oil, yogurt, eggs, and vanilla extract until smooth.
  • In another bowl, whisk together the flour, brown sugar, baking soda, baking powder, salt, cinnamon, ginger, and nutmeg.
  • Gradually add the dry ingredients to the wet ingredients, mixing just until combined.
  • Fold in the shredded carrots and any optional nuts or dried fruit.
  • Pour the batter into the prepared loaf pan and smooth the top.

Baking

  • Bake for 50-60 minutes or until a toothpick inserted in the center comes out clean.
  • While the loaf is baking, prepare the cream cheese topping. In a bowl, beat together the butter, cream cheese, powdered sugar, heavy cream, vanilla extract, and a pinch of salt until smooth.
  • Once the loaf has cooled, spread the cream cheese topping over the top.

Notes

Make sure to use finely shredded carrots for a smoother texture. If you don’t have coconut oil, any neutral oil will work well. Feel free to adjust the spices according to your taste. More cinnamon or extra nutmeg can enhance the flavors. Don’t overmix the batter; just stir until the dry ingredients are incorporated for a tender loaf.
