Sourdough Carrot Cake Bread

What if your sourdough bread tasted like carrot cake? This sourdough carrot cake bread is exactly that — a soft, lightly sweetened loaf packed with fresh shredded carrots, warm cinnamon, and all the depth of flavour that only a long sourdough fermentation can deliver. And yes, there’s a whipped cream cheese butter to go with it. You’re welcome.
It’s a hybrid recipe that lives beautifully between bread and cake. Not quite one, not quite the other — just something uniquely delicious that you’ll want to make on repeat.

Why make this recipe?

Because sourdough adds a depth of flavour that no commercial yeast can replicate. The long fermentation tenderizes the crumb, improves digestibility, and creates that subtle tang that perfectly balances the sweetness and spice. It’s also a brilliant way to use your active starter without committing to a classic rustic loaf.

Role of the ingredients

Active sourdough starter — The engine of the recipe — it leavens the dough while developing that complex, slightly tangy flavour we love.
Unbleached all-purpose flour — Provides a balanced structure with enough gluten for good shape without making the bread too dense.
Filtered water — Chlorinated water can harm the natural yeasts and bacteria in your starter, so filtered water is always preferred.
Egg — Enriches the dough, adds lightness, and helps achieve a beautiful golden crust.
Shredded carrots — Bring moisture, natural sweetness, and gorgeous colour. Note: they will release water during mixing, which is exactly why we use less water in this recipe.
Sugar — Also feeds the starter while delivering the classic sweetness of carrot cake.
Fine sea salt — Strengthens the gluten structure and balances all the flavours.
Ground cinnamon — The signature spice of carrot cake, perfuming every bite of the crumb.
Softened butter — Enriches the dough for a tender, rich-tasting result.

For the whipped butter:
Unsalted butter — Forms the creamy base of the whipped butter — at room temperature for easy whipping.
Cream cheese — Adds that signature tangy creaminess of classic cream cheese frosting.
Powdered sugar — Dissolves perfectly for a smooth, silky, lump-free whipped butter.
Vanilla paste — Delivers an intense vanilla flavour with beautiful visible seeds throughout.

Why we love this recipe

This carrot cake bread is a creative and delicious way to use your active starter — and a recipe that impresses as much as it satisfies. The long fermentation improves digestibility and builds flavours you simply can’t get any other way. It’s perfect for brunch or breakfast, and the whipped butter comes together in just 5 minutes to elevate every single slice.

Tips

Make sure your starter is active and bubbly — fed 4 to 12 hours before using, at or just past its peak. Don’t be tempted to add more water at the start: the carrots will release moisture as the dough mixes. Grate your carrots finely so they blend seamlessly into the dough. Handle the dough gently during shaping — you don’t want to deflate it completely. And the cold fermentation can go up to 16 hours, making it easy to bake fresh bread in the morning!

Storage

This bread keeps well wrapped at room temperature for 2 to 3 days. You can also slice and freeze it for up to 2 months — perfect for toasting a slice whenever the craving hits! The whipped cream cheese butter keeps in an airtight container in the refrigerator for up to 1 week. Take it out 15 minutes before serving so it softens back to that perfect creamy consistency.
