An overnight rest in the fridge does more than save you time on bake day. It changes a sticky, slack dough into one you can roll cleanly at half-inch thick without reaching for extra flour.
That cold ferment also unlocks a yeastier, more complex flavor, the same reason artisan bakers prefer a long, slow rise. The payoff in these mini donuts is a crumb that’s both tender and airy, with a crisp cinnamon shell that shatters on the first bite. It’s a weekend project that yields forty something worth the wait.
Why chill the dough overnight?
Chilling the dough overnight does two things you’ll notice the next day. First, the flour fully hydrates, so the dough rolls out smoothly without sticking or tearing. Second, that long, cold rise develops a deeper, yeastier flavor, like the difference between quick bread and a long-fermented one.
And cold dough is far less sticky; you won’t need to dust on extra flour, which would toughen the crumb. You’ll see the difference when you shape them: the dough feels supple, not tacky.
The final texture is lighter and more complex than any same-day version.
What makes the crumb tender yet chewy?
The balance comes from two things: the flour and how the gluten is built. A high-protein all-purpose flour, around 11-12%, gives enough structure to trap steam and create an airy interior without turning tough.
The dough gets a long mix, around 15 minutes total, so the gluten network is fully developed. That’s what gives mini donuts that pleasant chew, not a bready density. And the butter is added gradually, piece by piece, so it emulsifies into the dough evenly.
If you rush it, the dough feels greasy and the crumb turns dense. Done right, the inside is soft with a slight spring.
Why toss the donuts in cinnamon sugar while still warm?
The 30-second rest after frying is crucial. If you toss them too hot, the sugar melts into a sticky mess; too cool, it barely clings. At that brief window, the surface is still tacky enough to grab the cinnamon sugar, and the heat slightly melts the sugar grains so they form a thin, crunchy shell.
The ratio here is generous: a full cup of sugar to three tablespoons cinnamon. That might seem like a lot, but it ensures each bite has a bold cinnamon kick without the spice becoming harsh. You’ll taste it evenly on every donut, not just the first one.

A few things about the ingredients
Active dry yeast: Proof it in the warm milk with a little sugar until foamy to make sure it’s alive.
Whole milk: Use whole milk for richness; skim or 2% won’t give the same tender crumb.
All-purpose flour: A high-protein AP flour (11-12%) gives the right chew without being tough.
Vanilla bean paste: Use real vanilla bean paste for the best flavor; extract works but is less intense.
Neutral oil for frying: Use a high-smoke-point neutral oil like canola or vegetable; olive oil will burn.
The first time, I tried to roll it after an hour in the fridge; it stuck to everything and I had to add so much flour the donuts were tough.
How to shape and fry mini donuts without a greasy mess
Roll and cut the dough
Roll the cold dough to a clean 1/2-inch thickness. If it springs back, let it rest a few minutes. Use a well-floured cutter; press straight down, don’t twist, twisting seals the edges and prevents a good rise.
Punch the holes, then proof
Use a straw or small cutter to remove the center. Arrange on parchment squares, cover loosely, and let rise until puffy, about 45 to 50 minutes. When you poke one gently, the indentation should remain and slowly fill.
Test the oil temperature
Heat oil to 350°F. Drop a scrap dough piece in; it should bubble steadily and float within seconds.
If it sinks and barely bubbles, the oil’s too cool and will make greasy donuts. If it browns in under 60 seconds, it’s too hot.
Fry in batches, turning often
Lower up to 6 donuts into the oil, don’t crowd. Fry, flipping every 30 seconds, for 3 to 4 minutes total until deep golden brown. The first batch is your gauge: adjust heat if needed.
The donuts should puff and develop a ring of bubbles.
Toss in cinnamon sugar while warm
Let the fried donuts rest on a rack for 30 seconds, no longer, no shorter. Then toss them in the cinnamon sugar mix while still warm. You’ll see the sugar cling and form a thin, crunchy shell as it cools.
Mini Donuts
Ingredients
Doughnuts
- 2 1/4 tsp active dry yeast
- 1 cup whole milk, lukewarm 250g
- 1/4 cup sugar 50g
- 4 1/2 cups all-purpose flour 565g
- 1 tsp salt 5g
- 2 large eggs, at room temperature about 100g
- 1 tsp vanilla bean paste
- 1/2 cup unsalted butter, at room temperature 113g
- Neutral oil such as canola, extra light olive oil, or vegetable oil for frying
Cinnamon Sugar Coating
- 1 cup granulated sugar 200g
- 3 Tbsp cinnamon reduce slightly if you don’t like strong cinnamon flavor
Instructions
Doughnuts
Activate Yeast Mixture:
In a small bowl, whisk together the yeast, milk, and 2 Tbsp of the sugar. Let stand for 10-15 minutes until foamy.Mix Dough Base:
In the stand mixer bowl with the dough hook, combine the flour, salt, and remaining 2 Tbsp sugar. Mix briefly. Add the eggs, vanilla, and the foamy yeast mixture. Mix on low for 2-3 minutes until dough begins to come together (it may seem a bit dry). Then increase to medium and mix for 10 minutes until soft and smooth.Incorporate Butter:
Reduce speed to low and incorporate the butter piece by piece, waiting until each addition is fully absorbed (3-4 minutes total). Once all butter is added, increase to medium and mix for 5 more minutes until the dough is very soft and smooth.Chill Dough Overnight:
Move the dough to a greased bowl, cover tightly with plastic wrap, and chill overnight in the refrigerator (see notes).Roll Dough Thick:
Prepare two sheet pans with parchment paper squares. On a well-floured surface, roll the dough to a thickness of 1/2-inch (1.25 cm).Cut Doughnut Shapes:
Using a 1 3/4-inch (4.5 cm) round cutter, stamp out circles. With a very small round cutter or a milkshake straw (I used a metal bubble tea straw), punch a hole in the middle of each. Arrange on the parchment squares (several per sheet). Repeat with all dough; press scraps together and re-roll. Use scrap doughnuts for the first test fry as they may be irregular.Proof Shaped Doughnuts:
Loosely cover the shaped doughnuts with plastic wrap and allow to rise for 45-50 minutes until puffy. When lightly poked, a small indentation should remain and slowly spring back.Heat Oil and Mix Sugar:
During the last 15-20 minutes of proofing, heat neutral oil to 350°F (175°C) in a large heavy-bottomed pot (cast iron works great) or deep fryer. The oil depth should be enough for doughnuts to float. Set a wire rack over a parchment-lined baking sheet. In a medium bowl, stir together the granulated sugar and cinnamon.Fry and Coat Doughnuts:
Once oil is at temperature, test with a few dough scraps or re-rolled doughnuts. Carefully lower up to 6 doughnuts at a time into the hot oil. Fry, turning every 30 seconds, for 3-4 minutes until golden brown. Remove with a slotted spoon and transfer to the cooling rack. Let cool for 30 seconds, then toss in the cinnamon sugar mixture. Repeat with remaining doughnuts.Store and Reheat:
Best consumed on the day they are made. Store leftovers in an airtight container and briefly reheat in the microwave.
Cinnamon Sugar Coating
Storage and Serving
These mini donuts are best within a few hours of frying, when the exterior is still crisp and the interior soft. The cinnamon sugar coating starts to soften after about 4 hours, so if you’re serving them for an event, fry them as close to serving time as possible.
Leftovers keep in an airtight container at room temperature for up to 1 day. The texture softens overnight, but a quick 10-second zap in the microwave restores some warmth and softness. Don’t refrigerate them; the fridge dries out the crumb and makes the coating sticky.
Freezing isn’t recommended because the texture degrades noticeably upon thawing. If you want to prepare ahead, shape the donuts and freeze them unbaked on a parchment-lined tray, then transfer to a freezer bag. Fry directly from frozen, adding about 1 minute to the cook time.
Swapping for a lighter crumb, or a dairy-free one
Active dry yeast: Instant yeast, same amount by weight, no proofing needed. Mix instant yeast directly with the flour.
The dough will rise faster, so check it earlier during proofing. No difference in flavor or texture.
Whole milk: 2% or oat milk; same volume. 2% milk yields a slightly less tender crumb, still fine.
Oat milk works but the dough may feel a bit tighter; expect a less rich, slightly denser interior. Butter stays for tenderness.
All-purpose flour: Gluten-free 1-to-1 flour blend (with xanthan gum), same weight. The dough will be stickier and harder to roll; chill overnight helps. The crumb will be more cake-like, less chewy.
Don’t expect the same stretchy, airy texture.
Tips
- Use a metal bubble tea straw to punch the holes cleanly and consistently, and flour the cutter between stamps to prevent sticking.
Frequently Asked Questions
Can I skip the overnight chill and just let the dough rise at room temperature?
You can, but the dough will be much stickier and harder to roll without extra flour, which toughens the crumb. The overnight chill also develops a deeper, yeastier flavor that a quick rise can’t match. If you skip it, expect a denser, less tender donut.
Why did my donuts come out greasy?
The most common cause is oil that’s too cool. Drop in a test scrap: it should bubble vigorously and float right away. If it sinks and barely bubbles, the oil is below 350°F and the donuts absorb too much fat before the crust sets.
Crowding the pot also drops the temperature, so fry no more than six at a time.
Can I bake these mini donuts instead of frying?
Baking will give you a cake-like texture, not the airy, chewy crumb you get from frying. The dough is formulated for deep-frying, so baked donuts will be denser and won’t develop the same golden crust. If you want to bake, expect a different result and adjust expectations.
How do I know when the oil is at the right temperature without a thermometer?
Drop a small piece of dough scrap into the oil. If it sinks to the bottom and barely bubbles, the oil is too cool. If it floats immediately and bubbles steadily, the oil is around 350°F.
It should take about 60 seconds to turn light golden brown, any faster and the oil is too hot.
Can I make the dough ahead and freeze it?
Yes, shape the donuts and freeze them unbaked on a parchment-lined tray, then transfer to a freezer bag. Fry directly from frozen, adding about 1 minute to the cook time. The texture won’t be quite as light as fresh, but it’s a good make-ahead option.
