The Ultimate Old-Fashioned Cake Donut – Tender, Rich & Slightly Tangy
Sour cream is the secret to incredibly moist, tender, and flavorful cake donuts with a slight tang that balances the sweetness. These are not yeasted donuts—they’re cake donuts, meaning they’re dense, satisfying, and perfect for glazing or sugaring.

🍩 The Classic Recipe
Prep Time: 25 mins (+ optional chill) | Cook Time: 2-3 mins per batch | Yield: 12-15 donuts + holes
Ingredients
For the Donuts:
- 2 ¼ cups (280g) all-purpose flour (plus more for dusting)
- 1 ½ tsp baking powder
- ½ tsp baking soda
- ½ tsp salt
- ½ tsp ground nutmeg (traditional, can sub cinnamon)
- ⅔ cup (135g) granulated sugar
- 2 large eggs, room temperature
- ½ cup full-fat sour cream, room temperature
- 2 tbsp unsalted butter, melted and cooled
- 1 tsp vanilla extract
- Neutral oil for frying (vegetable, canola, or peanut)
For the Vanilla Glaze:
- 2 cups (240g) powdered sugar, sifted
- ¼ cup whole milk or cream

- Pinch of salt
Optional Toppings:
- Cinnamon sugar (½ cup sugar + 1 tbsp cinnamon)

- Plain powdered sugar
👨🍳 Step-by-Step Instructions
1. Make the Dough:
- In a medium bowl, whisk together flour, baking powder, baking soda, salt, and nutmeg.
- In a large bowl, whisk sugar and eggs until pale and slightly thickened (2 mins).
- Whisk in sour cream, melted butter, and vanilla until smooth.
- Gently fold dry ingredients into wet until just combined. Do not overmix—dough will be soft and sticky.
- Optional but recommended: Cover dough and chill for 30-60 minutes. This makes rolling easier.
2. Roll & Cut:
- On a generously floured surface, pat or roll dough to ½-inch thickness.
- Use a donut cutter (or 3-inch round cutter + 1-inch for holes) to cut shapes. Re-roll scraps once.
- Place cut donuts on a floured baking sheet.
3. Fry to Perfection:
- In a heavy pot or Dutch oven, heat 2-3 inches of oil to 350°F (175°C). Use a thermometer!
- Carefully slide 2-3 donuts into the oil. Fry for 60-90 seconds per side until golden brown.
- Remove with a slotted spoon and drain on a wire rack set over a baking sheet.
4. Glaze & Finish:
- For Vanilla Glaze: Whisk all glaze ingredients until smooth. Dip warm donuts into glaze, let excess drip off, and return to rack.
- For Cinnamon Sugar: While donuts are still hot but not glazed, toss in cinnamon sugar mixture.
- Let set for 10-15 minutes before serving.
🔥 Pro-Tips for Donut Success
- Oil Temperature is Crucial: Too hot = burnt outside/raw inside. Too cool = greasy donuts. Keep it at 350°F.
- Room Temperature Ingredients: Ensures even mixing and tender texture.
- Don’t Overmix Dough: Overworking develops gluten = tough donuts.
- Fry in Small Batches: Prevents oil temp drop and overcrowding.
- Drain on a Rack, Not Paper Towels: Prevents soggy bottoms.
