Ingredients

For the Dough

  • 3 cups bread flour
  • ½ cup active sourdough starter
  • ¾ cup warm milk
  • 2 tablespoons sugar
  • 1 egg
  • 3 tablespoons softened butter
  • 1 teaspoon vanilla extract
  • 1 teaspoon salt

Mix-Ins

  • ⅓ cup rainbow sprinkles (jimmies work best)

Optional Vanilla Glaze

  • 1 cup powdered sugar
  • 2 tablespoons milk
  • Extra sprinkles for topping

Equipment You’ll Need

Making this bread doesn’t require any fancy tools. Here’s what helps:

  • Large mixing bowl
  • Measuring cups and spoons
  • Loaf pan
  • Dough scraper (optional)
  • Kitchen towel or plastic wrap
  • Cooling rack

How to Make Funfetti Sourdough Bread

Step 1: Mix the Dough

In a large bowl, combine the active sourdough starter, warm milk, sugar, egg, softened butter, and vanilla extract.

Stir everything together until smooth.

Add the bread flour and salt. Mix until a shaggy dough forms. Once combined, knead the dough for about 8–10 minutes until it becomes soft, smooth, and elastic.

You can knead by hand or use a stand mixer with a dough hook attachment.

The dough should feel slightly tacky but not sticky.


Step 2: Fold in the Sprinkles

Once the dough is smooth, gently fold in the rainbow sprinkles.

Be careful not to overmix. Too much mixing can cause the colors to bleed into the dough, making the loaf muddy instead of colorful.

Jimmies-style sprinkles work best because they hold their color better during baking.


Step 3: First Rise

Place the dough into a lightly greased bowl and cover it with a towel or plastic wrap.

Let the dough rise in a warm place for about 4–6 hours, or until doubled in size.

Because sourdough fermentation depends on temperature, your rise time may vary slightly.

A warm kitchen will speed up the process, while a cooler kitchen may take longer.


Step 4: Shape the Dough

After the first rise, gently punch down the dough and shape it into a loaf.

Transfer the dough into a greased loaf pan.

Cover again and allow the dough to rise for another 1–2 hours until puffy.

The loaf should rise slightly above the edge of the pan before baking.


Step 5: Bake the Bread

Preheat your oven to 350°F (175°C).

Bake the loaf for 30–35 minutes or until golden brown on top.

The bread should sound slightly hollow when tapped on the bottom.

If the top begins browning too quickly, loosely cover it with foil during the final 10 minutes of baking.

Once baked, remove the bread from the pan and let it cool completely on a wire rack.


Step 6: Add the Glaze

In a small bowl, whisk together powdered sugar and milk until smooth.

Drizzle the glaze over the cooled loaf and top with extra rainbow sprinkles.

The glaze adds sweetness and gives the bread a beautiful bakery-style finish.


Tips for the Best Funfetti Sourdough Bread

Use Active Starter

Your sourdough starter should be bubbly and active before mixing the dough. This helps create a light and fluffy texture.

Don’t Overmix the Sprinkles

Fold them in gently to keep the colors bright and vibrant.

Use Bread Flour

Bread flour gives the loaf better structure and softness compared to all-purpose flour.

Let the Bread Cool

Allow the loaf to cool fully before glazing and slicing. This keeps the texture soft and prevents the glaze from melting.

Toast Leftovers

This bread tastes incredible lightly toasted with butter.


Flavor Variations

One of the best things about this recipe is how easy it is to customize.

Birthday Cake Version

Add white chocolate chips for an even sweeter birthday cake flavor.

Chocolate Funfetti

Mix in mini chocolate chips with the sprinkles.

Lemon Funfetti

Add lemon zest to the dough for a fresh citrus twist.

Cinnamon Sugar

Sprinkle cinnamon sugar into the dough before shaping.


How to Store

Store the bread in an airtight container or wrapped tightly at room temperature for up to 3 days.

For longer storage, refrigerate for up to 1 week.

You can also freeze slices individually and toast them whenever needed.


Serving Ideas

This colorful bread is perfect served:

  • Warm with butter
  • Toasted for breakfast
  • Alongside coffee or tea
  • As a fun dessert loaf
  • For birthday brunches
  • With cream cheese frosting

It also makes amazing French toast.


Frequently Asked Questions

Can I use sourdough discard?

This recipe works best with active sourdough starter because it helps the bread rise properly.

What sprinkles work best?

Jimmies-style sprinkles are ideal because they don’t bleed as much as nonpareils.

Can I make it overnight?

Yes. After shaping the loaf, refrigerate overnight and bake the next day.

Can I skip the glaze?

Absolutely. The bread is delicious even without it.


Final Thoughts
