1 pkg. dry yeast
1/4 c. warm water
1 tsp. sugar
2 c. flour
1/2 tsp. salt
3/4 c. butter
2 eggs, separated
1/4 c. sugar
1 tsp. vanilla
1 can of Solo filling
Powdered sugar

Sprinkle yeast over warm water. Add 1 teaspoon sugar. Let stand 10 minutes. Sift together flour and salt. Cut in butter until mixture resembles coarse meal. Blend in egg yolks and softened yeast. Mix until a smooth ball is formed. Beat egg whites until stiff, but not dry. Gradually beat in 1/4 cup sugar. Continue beating until stiff and peaked. Fold in vanilla.

Divide dough in half. Roll out each into a 9"x13" rectangle. Spread with egg white mixture and Solo filling. Roll up like jelly roll. Place on baking sheet. Make 1/2" deep cut in center of each roll. Bake immediately at 375 degrees for 22 minutes. When warm, sprinkle with powdered sugar.
