Ingredients
For the Dough
- 100g active sourdough starter
- 300g bread flour
- 120g whole milk, room temperature
- 1 large egg
- 50g granulated sugar
- 50g unsalted butter, softened
- 1 teaspoon vanilla extract
- 5g salt
Funfetti Add-Ins
- ½ cup rainbow jimmies sprinkles (avoid nonpareils)
Optional Topping
- Extra rainbow sprinkles
- Coarse sugar
- Egg wash (1 egg beaten with 1 tablespoon milk)
Instructions
Step 1: Mix the Dough
In a large mixing bowl, combine:
- Active sourdough starter
- Milk
- Egg
- Sugar
- Vanilla extract
Mix until smooth.
Add bread flour and salt.
Mix until a rough dough forms.
Step 2: Knead the Dough
Add softened butter gradually while kneading.
Continue kneading for 8–10 minutes until the dough becomes smooth, elastic, and slightly tacky.
Step 3: Bulk Fermentation
Place the dough in a lightly greased bowl.
Cover and allow it to rise at room temperature for 4–6 hours, or until noticeably puffy.
The exact time will depend on the strength of your starter and room temperature.
Step 4: Add the Sprinkles
Turn the dough onto a lightly floured surface.
Gently flatten into a rectangle.
Sprinkle the rainbow jimmies evenly over the dough.
Fold and knead gently until the sprinkles are distributed throughout.
Avoid overworking the dough to prevent color bleeding.
Step 5: Shape the Loaf
Shape the dough into a loaf.
Place into a greased 9×5-inch loaf pan.
Cover loosely.
Step 6: Final Proof
Allow the dough to rise until it reaches about 1 inch above the rim of the pan.
This may take 2–4 hours depending on temperature.
Step 7: Prepare for Baking
Preheat oven to 350°F (175°C).
Brush the top with egg wash.
Sprinkle additional rainbow sprinkles and coarse sugar over the surface if desired.
Step 8: Bake
Bake for 35–40 minutes, or until golden brown and the internal temperature reaches approximately 190°F (88°C).
If the top browns too quickly, loosely cover with foil during the final 10 minutes.
Step 9: Cool
Remove from the pan and cool completely on a wire rack before slicing.
