Sourdough Starter Birthday Cake Batter Bread 🎂🍞
Where Funfetti Meets Fermentation for the Ultimate Celebration Loaf
What do you get when you cross a tangy, soft sourdough loaf with birthday cake batter? Pure magic. This Sourdough Starter Birthday Cake Batter Bread is soft, slightly sweet, and bursting with rainbow sprinkles and vanilla flavor. It’s part sourdough, part dessert, and entirely delicious.
Whether you’re celebrating a birthday, a special occasion, or just need something whimsical on your breakfast table, this loaf delivers joy in every slice.
Why I Love This Recipe
This bread feels like a party in a pan. It has that complex sourdough depth, but it’s softened by a little sugar, vanilla, and a hint of almond. The sprinkles are folded in gently so they keep their color, and the vanilla glaze on top adds a perfect bakery finish.
Plus, it’s flexible—you can ferment it overnight or bake it same-day depending on your schedule.
Ingredients
For the Dough:
- ½ cup active sourdough starter (fed and bubbly)
- 2¼ cups all-purpose flour
- ¼ cup sugar
- ½ cup warm milk (not hot)
- ¼ cup plain yogurt or sour cream
- 1 tsp vanilla extract
- ½ tsp almond extract (optional but amazing)
- ¾ tsp salt
- 3 tbsp softened butter
- ⅓ cup rainbow sprinkles (use jimmies-style to avoid color bleed)
For the Vanilla Glaze:
- 1 cup powdered sugar
- 2 tbsp milk
- ½ tsp vanilla extract
- Extra sprinkles, for garnish
Fun Variations & Notes
- Swap almond extract with lemon or orange zest for a citrusy twist
- Use chocolate chips instead of sprinkles for a birthday brownie bread vibe
- Add a tablespoon of cake mix to enhance that nostalgic birthday cake flavor
- Don’t use nonpareils (tiny round sprinkles)—they bleed easily and stain the dough
How to Make Sourdough Birthday Cake Batter Bread
🥣 Step 1: Make the Dough
In a large bowl, combine the sourdough starter, flour, sugar, warm milk, yogurt, vanilla, almond extract (if using), and salt. Mix until shaggy. Add softened butter and knead (by hand or mixer) until smooth and elastic—about 8–10 minutes.
⏳ Step 2: Bulk Ferment
Cover and let rise at room temp for 4–6 hours or until doubled. If your kitchen is cool, ferment longer or let it rest overnight in the fridge for a slow, flavorful rise.
🌈 Step 3: Add Sprinkles
Flatten the dough gently, scatter in the rainbow sprinkles, and fold gently to distribute. Don’t overmix—this keeps the sprinkles from bleeding.
🧈 Step 4: Shape & Proof
Form into a loaf or place into a buttered 9×5-inch pan. Cover and proof for 2–4 hours, or until the dough is puffy and just above the pan rim.
🔥 Step 5: Bake
Preheat your oven to 350°F (175°C). Bake for 35–40 minutes, tenting with foil halfway if the top browns too quickly. Tap the top—if it sounds hollow, it’s done.
❄️ Step 6: Cool & Glaze
Cool completely before glazing. Mix the powdered sugar, milk, and vanilla into a smooth glaze. Drizzle generously and top with extra sprinkles for that birthday-ready look.
Tips for Success
- Use an active starter for the best rise and texture
- Warm your milk gently—not hot, or it’ll harm the starter
- Avoid overproofing after shaping, especially if using a sweet dough
- Cool completely before glazing so the drizzle doesn’t melt off
