In a bowl, combine yeast, sugar, salt, and 1 cup of flour.

In a saucepan over medium heat, heat butter and 1 cup of water until very hot (125°F).

With a mixer at low speed, beat the liquid into the dry ingredients.

At medium speed, beat for 2 minutes.

Reserve 1 egg white; beat the remaining egg and egg yolk with 1 cup of flour; beat for 2 minutes.

Stir in 2 1/4 cups of flour.

Turn the dough onto a floured surface and knead until smooth and elastic, about 5 minutes, working in about 1/4 cup of flour while kneading.

Shape the dough into a ball; cover and let rest for 15 minutes.

Preheat oven to 375 degrees F.

Grease 2 cookie sheets.

Cut the dough into eighths.

For 1 bunny; cut 1 piece of dough in half; shape half into a ball, with a chocolate kiss in the center, for the body.

Place on cookie sheet.

Cut the other half in half; shape half into a ball; brush with egg white; place next to the large ball, tucking slightly under it for the head.

For the remaining half, pinch off a 3/4 inch piece for the tail and shape 2 ears.

Brush the tail and ears with egg whites; tuck slightly under the bunny.

Bake for 15 minutes or until browned.

Cool on a rack.

Repeat to make 4 more.

Mix confectioners' sugar with about 1/4 tsp. of water and a hint of red food coloring (for pink) use to draw a face on the bunnies.

If desired, tie bows around the bunnies' necks.
