- # 1/2 teaspoon vanilla extract
- # 1/3 cup melted unsalted butter, cooled briefly

Preparation
Step 1
For doughnuts: Whisk first 5 ingredients in medium bowl to blend. Using electric mixer, beat sugar and eggs in large bowl until very thick, about 3 minutes. Beat in orange peel and vanilla. Gradually beat in butter; beat in sour cream in 2 additions. Gently fold in dry ingredients in 4 additions (dough will be slightly sticky). Cover; set aside 1 hour.
For glaze: Combine powdered sugar and maple extract in medium bowl. Add 4 tablespoons cream; whisk until smooth. Whisk in additional cream, 1 teaspoon at a time, to form medium-thick glaze. Cover and let stand up to 3 hours.
Sprinkle 2 rimmed baking sheets lightly with flour. Press out 1/3 of dough on lightly floured surface to 1/2- to 2/3-inch thickness. Using 2 1/2-inch-diameter round cutter, cut out dough rounds. Arrange on floured sheets. Repeat with remaining dough in 2 more batches. Gather all dough scraps. Press out dough; cut out more dough rounds until all dough is used.
Using 1-inch-diameter round cutter, cut out center of each dough round to make doughnuts and doughnut holes.
Line 2 baking sheets with several layers of paper towels. Pour oil into large deep skillet to depth of 1 1/2 inches. Attach deep-fry thermometer and heat oil to 365°F to 370°F. Fry doughnut holes in 2 batches until golden brown, turning once, about 2 minutes. Using slotted spoon, transfer to paper towels. Fry doughnuts, 3 or 4 at a time, until golden brown, about 1 minute per side. Using slotted spoon, transfer doughnuts to paper towels. Cool doughnuts and doughnut holes completely. Working with 1 doughnut at a time, spread glaze over 1 side. Arrange doughnuts, glaze side up, on rack.
Let glaze set at least 30 minutes. Coat doughnut holes with same glaze
