Chocolate donuts with coffee glaze

Ingredients:

Chocolate donuts

• 1.5 cups premium flour
• 1 cup granulated sugar
• 0.5 cup cocoa
• 3/4 teaspoon coarse salt
• 1 teaspoon baking powder
• 0.5 tsp of soda
• 0.5 cups of brewed coffee at room temperature
• 6 tablespoons of sour milk or kefir
• 6 tablespoons of vegetable oil
• 1 tsp vanilla extract
• 1 large egg
• Special equipment: 12-piece donut pan; pastry bag

Coffee glaze

• 1 cup powdered sugar
• 2 tablespoons brewed coffee, or more as needed
• 1 tbsp. milk
• 1 cup chopped toasted hazelnuts
• Sprinkles for decoration

Preparation:

1. Preheat oven to 375°F (190°C). Spray a donut pan with cooking spray and set aside.
2. Chocolate donuts:
   
   In a large bowl, combine the flour, granulated sugar, cocoa, salt, baking powder, and baking soda. In a separate medium bowl, combine the coffee, sour milk, butter, vanilla, and egg until smooth. Add the liquid mixture to the flour mixture and knead until smooth.
3. Transfer the batter to a pastry bag. Fill each donut cavity about three-quarters full with batter. Bake until a toothpick inserted into the donut comes out clean, about 12 minutes. Let the donuts cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
4. Coffee glaze:
   
   Mix powdered sugar, coffee, and milk in a bowl until smooth. If the glaze seems too thick, add a little more coffee. Dip each donut halfway into the glaze and let any excess drip off. Sprinkle with hazelnuts and sprinkles. Let set for about 30 minutes.
