- 1 large egg
- 1 tsp vanilla extract
- 2 1/2 cups flour, plus more for kneading
- 1/2 tsp salt
- 1/4 tsp baking soda
- Coating:

Preparation
Step 1
Place water in bowl of stand mixer and sprinkle yeast over. Let stand until bubbly, 5 to 10 minutes. Stir in butter, sour cream, sugar, egg and vanilla. Beat in 2 cups of flour, the salt and baking soda until incorporated. Add remaining flour and continue to mix until a smooth, soft dough forms.
Turn out dough on a lightly floured surface, reserving mixing bowl. Knead dough until smooth, about 3 minutes, adding in more flour if dough is sticky. Do not exceed 2 additional tablespoons of flour.
Place dough back in mixing bowl and cover with plastic wrap. Let rise in a warm place until doubled in size, about 1 hour.
In a small bowl, mix cinnamon and sugar for coating. Place melted butter in a small, shallow dish.
Lightly grease a 12-cup muffin pan, and then flour the cups and tap out excess flour.
Punch down dough to deflate. Form into a long cylinder and then divide into 12 equal portions. Divide each portion into 6 equal pieces and roll each piece into a ball.
For each bun, coat six balls with melted butter and then roll them in cinnamon sugar. Arrange five balls in the bottom of a prepared muffin cup. Using your fingertip, make a small well in the center and press in the sixth ball.
Repeat with remaining dough and muffin cups. Cover buns loosely with plastic wrap and let rise in a warm place until puffy and have doubled in size, about 40 minutes.
Preheat oven to 350F. Bake buns until golden, 20-22 minutes. Let cool in pan 5 to 10 minutes and then tilt pan and gentil tap on a work surface to release buns. If needed, use a knife to help release them.
Place buns on a wire rack over a cookie sheet (line with waxed or parchment paper for easy clean up). In a small bowl, mix glaze ingredients and stir until smooth. Drizzle each bun with glaze and sprinkles, if using.
