Old Fashioned Sour Cream Donuts are crumbly, tender, and easy for beginners with no yeast. Crisp nooks & crannies soak up a sweet vanilla glaze with a hint of warm spice. Serve with coffee.
In a bowl, whisk 2 ¼ cups Bleached Cake Flour, 1 ½ teaspoon Baking Powder, 1 teaspoon Salt and ½ teaspoon Ground Nutmeg.
In a large bowl or stand mixer, cream 2 tablespoon Unsalted Butter and ½ cup White Granulated Sugar together. Add the 2 Egg Yolks and ½ cup Sour Cream and combine.
Pour the wet ingredients into the dry ingredients. With a spoon or spatula (do not use an electric mixer), stir by hand. The dough should be flakey but not overly dry or wet.
Wrap the dough in plastic wrap, spray the top of the dough with Non-stick cooking spray and refrigerate for 1 hour.
Remove the plastic wrap and roll the dough out on floured Parchment Paper until it's ½-inch thickness. Make sure not to over-knead the dough. Use a donut cutter or 2 concentric circle cutters to cut out all the donuts. Reroll the dough as needed to get about 6-8 donuts and holes. Put the donuts back in the refrigerator while heating the oil.
Make the glaze. In a medium saucepan over low heat, add the ¼ cup Milk and 1 teaspoon Vanilla Extract. Gradually add 2 cups Powdered Sugar and whisk until smooth. Remove from heat. Put the saucepan in some warm water and occasionally stir to keep a hardened layer from forming while you fry the donuts.
Into a large, deep pan, add about 3 cups Vegetable oil and heat to 325 F. Add the donuts two-three at a time so they don't touch. Fry on each side for 2 minutes until they are golden brown and transfer to a wire rack over paper towels or a baking sheet. Donut holes only need about 45 seconds per side.
The oil temperature will decrease when you add the donuts. Let it come back up to 325 degrees between batches.
As soon as the donuts are cool enough to touch but still warm, dip them into the glaze and flip to cover the entire donut. Transfer to the cooling rack for about 5 minutes until glaze is set and cooled. If necessary, you can put the donuts in the microwave for 10-15 seconds to warm them up again.
Donuts are best eaten the same day but can be stored in an airtight container at room temperature for a few days.
Notes
Baking recipes are best in measured in weight (grams) rather than volume (cups) but you can get away with it in this recipe. It might be a bit more inconsistent from one baker to the next.
Cake flour is HIGHLY recommended for a light texture and loose crumb. I have made this recipe by substituting ¼ cup cornstarch and 2 cups all-purpose flour. The texture was denser and coarser than I would expect it to be. However, it does work in a pinch.
A doughnut size is about 3.5 outer circle and 1.25 inner circle. If you don't have a doughnut cutter, use anything close to that.
Sifting the cake flour and powdered sugar is recommended if you notice any lumps.
