Korean Sweet Rice Donut Recipe: Pillowy Soft With Crispy Edges

This recipe transforms simple sweet rice flour into donuts with crispy edges and a pillowy soft interior. The secret lies in the frying temperature and resting time between shaping and cooking.

I developed this method after testing multiple techniques to achieve the perfect balance of textures. The dough comes together quickly with just a few ingredients, then rests briefly before being shaped into rings.

When fried at the right temperature, these donuts develop a golden crust while staying airy inside. The contrast between the crispy exterior and tender center makes them irresistible.

Serve warm for the best experience, though they remain delicious at room temperature. This technique ensures consistent results every time.

Ingredients for Korean Sweet Rice Donut

A handful of pantry staples create donuts with crisp edges and airy centers.

The rice flour is non-negotiable—look for glutinous or sweet rice flour (despite the name, it contains no gluten). Bob’s Red Mill carries it, as do most Asian markets. The yeast needs to be fresh; check the expiration date. I’ve had best results with Fleischmann’s active dry yeast. For the oil, peanut or vegetable oil both work well for frying—just pick one with a high smoke point.

No rice flour? All-purpose flour with 2 tbsp cornstarch per cup gets you close but won’t have the same chew. If you skip the egg, add an extra tbsp of water and a tsp of oil to compensate. The sugar can be swapped for honey or maple syrup at a 1:1 ratio, but it may darken faster. For a richer flavor, brown sugar works beautifully in place of granulated.

Dough rests best in a warm spot—75-80°F is ideal. Fried donuts are best eaten the same day, but leftovers keep in an airtight container for 2 days. Reheat in a 350°F oven for 5-8 minutes to restore some crispness.

Step-by-Step Instructions for Korean Sweet Rice Donuts

Master the technique for achieving that signature pillowy interior with perfectly crisp edges.

Step 1: Activate Yeast and Prepare Dough

Combine the 2.25 tsp Active Dry Yeast with the 0.75 cup Lukewarm Water in a mixing bowl. Let it sit for 5-7 minutes until the mixture becomes frothy and cloudy—this confirms your yeast is alive and active. The water should be approximately 110°F; too hot will kill the yeast, too cold will prevent activation.

In a separate large bowl, whisk together the 2 cups Sweet Rice Flour, 0.33 cup Granulated Sugar, 0.5 tsp Salt, and 1 tsp Baking Powder. This gluten-free flour creates the characteristic chewy texture. Make a well in the center for the wet ingredients.

Step 2: Create and Rest the Dough

Pour the activated yeast mixture into the dry ingredients along with the 1 whole Egg and 2 tbsp Unsalted Butter (melted and cooled). Add the 1 tsp Vanilla Extract for depth of flavor. Mix with a wooden spoon until combined, then knead by hand for 5-7 minutes until smooth and slightly tacky.

The dough will be softer than traditional bread dough. Form it into a ball, cover with a damp towel, and let it rise in a warm place for 1-1.5 hours or until nearly doubled in size. This extended rise develops the proper texture and flavor.

Step 3: Shape and Proof the Donuts

Punch down the risen dough and turn it onto a lightly floured surface. Divide into 12 equal portions and roll each into a smooth ball. Use your thumb to create a hole in the center of each ball, then gently stretch to form a ring about 2.5 inches in diameter.

Place the shaped donuts on a parchment-lined tray, cover loosely with plastic wrap, and let them proof for 30-45 minutes. They should puff up slightly but not double in size. This second rise ensures airy centers while maintaining structure for crisp edges.

Step 4: Fry to Crispy Perfection

Heat the 4 cups Vegetable Oil in a deep pot to 350-360°F. The oil depth should be at least 2 inches to allow the donuts to float. Fry 2-3 donuts at a time to avoid crowding, which would lower the oil temperature.

Fry for 2-3 minutes per side until golden brown and crisp. Use a slotted spoon to turn them, and watch for the edges to develop a slightly darker color—that’s your crispy edge forming. Drain on a wire rack set over a baking sheet to maintain crispness.

Step 5: Coat and Serve Warm

While still warm, toss the donuts in a mixture of the 0.5 cup Powdered Sugar and 1 tsp Cinnamon (if using). The residual heat helps the coating adhere beautifully. For best results, coat them in batches while they’re still hot from the fryer.

Serve immediately while warm. The contrast between the crisp exterior and pillowy interior is most pronounced when fresh. These donuts are best enjoyed the same day, as the texture changes significantly once cooled completely.

Essential Equipment for This Recipe

Deep Fryer Setup

For consistent results, I recommend a 5-quart Dutch oven or enamel-coated pot for frying. The heavy base distributes heat evenly, preventing hot spots that can burn your donuts. I use my Le Creuset for this—it maintains 350-360°F perfectly. 🔥

Temperature Control

A candy or deep-fry thermometer is essential for monitoring oil temperature. I prefer the Taylor Precision model for its accuracy and durability. Clip it to the pot side and adjust heat as needed to maintain stable temperature during frying.

Dough Tools

Use a stand mixer with dough hook to save time and effort. My KitchenAid handles the sticky sweet rice dough beautifully. If kneading by hand, a wooden spoon and clean counter work well—just keep extra flour nearby for dusting.

Shaping Aids

A digital kitchen scale ensures equal portions for consistent cooking. I weigh my dough into 2.5-ounce balls before shaping. A donut cutter (2.5-inch ring) makes perfect circles, but your fingers work just as well for the hole.

Draining Station

Set up a wire rack over a baking sheet for draining fried donuts. This allows air circulation on all sides, preventing sogginess. I line my sheet with parchment paper for easy cleanup. Avoid paper towels—they can make the bottoms steam and lose crispness.

Coating Essentials

For the sugar coating, use a large paper bag or bowl with lid to toss warm donuts. The bag method is mess-free and ensures even coverage. Have your powdered sugar and cinnamon pre-mixed and ready before frying begins.
