Activate the Yeast
Combine warm milk and sugar in a small bowl. Sprinkle in the yeast and let it sit for 5–10 minutes until foamy.

Mix the Dough
In a large bowl, mix flour and salt. Add the yeast mixture, melted butter, egg, and vanilla. Knead by hand or with a mixer for 8–10 minutes until smooth and elastic.

First Rise
Place the dough in a greased bowl, cover with a towel, and let rise in a warm place for 1 to 1.5 hours, or until doubled in size.

Shape the Bunnies
Divide dough into 12 pieces. Roll each into a rope and coil into a spiral. Form a small ball for the head, attach it, and snip ears. Press raisins or chocolate chips in for eyes.

Second Rise
Place on parchment-lined baking sheets. Cover and let rise for another 30 minutes.

Egg Wash and Bake
Preheat oven to 350°F (175°C). Mix egg and water to make egg wash, then brush it on buns. Bake for 15–18 minutes or until golden brown.

Cool and Serve
Let cool slightly before serving. Enjoy warm or at room temperature.
