If you’re craving a warm, soft, and irresistibly sweet treat, these sourdough cinnamon donut balls (donut holes) are exactly what you need. Lightly crisp on the outside, soft and fluffy on the inside, and coated in a fragrant cinnamon sugar layer, this recipe transforms simple pantry ingredients into a bakery-style dessert you can easily make at home.

These homemade sourdough donut holes are perfect for breakfast treats, tea-time snacks, festive desserts, or even weekend baking fun with family.

Pro Tips for Perfect Sourdough Donut Balls
1. Use Active Starter
A bubbly, well-fed starter ensures better rise and fluffiness.
2. Don’t Overheat Milk
Milk should be warm, not hot, to protect yeast activity.
3. Maintain Proper Oil Temperature
Ideal frying temperature is around 330°F for even cooking without greasiness.
4. Don’t Overcrowd the Pan
Fry in small batches for consistent golden color.
5. Coat While Warm
Roll donut balls in cinnamon sugar immediately after frying for best adhesion.
Step-by-Step Guide: How to Make Sourdough Cinnamon Donut Balls
Step 1: Preparing the Dough Base
Warm the milk gently in a small saucepan until it feels warm to the touch—not hot.
In a large mixing bowl, combine:
- white flour
- white sugar
- salt
- egg
- warm milk
- active sourdough starter
Mix thoroughly using a wooden spoon or spatula until a soft dough forms.
Step 2: Kneading for Structure
Transfer the dough onto a lightly floured surface and knead for 3–5 minutes.
The dough should become:
- smooth
- elastic
- soft but not sticky
This step develops gluten, which helps create fluffy donut balls after frying.
Step 3: Shaping the Donut Balls
Divide dough into 24 equal portions.
A simple method:
- Cut dough in half
- Divide each half again
- Split into smaller equal pieces
Roll each portion into a smooth ball using your palms.
Place them on a lined tray with slight spacing.
Step 4: Proofing the Dough (Rising Stage)
Let the dough balls rise in a warm environment for about 1 hour.
If your kitchen is cool, create a warm proofing box:
- Preheat oven to low (about 100°F)
- Place a bowl of hot water inside
- Turn oven off
- Place tray inside and close door
The dough will become slightly puffed and airy.
Step 5: Preparing Cinnamon Sugar Coating
In a bowl, mix:
- sugar
- cinnamon
Set aside for coating after frying.
Step 6: Heating Oil for Frying
Heat oil in a deep pot or fryer to 330°F (165°C).
Proper temperature is important:
- too hot = burnt outside
- too cold = greasy donut balls
Step 7: Frying to Golden Perfection
Carefully drop a few dough balls into hot oil.
They will:
- sink first
- then float as they cook
Fry each side for about 3 minutes until golden brown.
Remove and drain on paper towels.
Step 8: Cinnamon Sugar Coating
While still warm, roll donut balls in cinnamon sugar mixture until fully coated.
The sugar melts slightly, forming a delicious crust.
