1 pkg. dry yeast (quick)
2 c. lukewarm milk
4 eggs, separated
1 tsp. vanilla
2 1/2 c. flour
1/2 tsp. salt
1 tbsp. sugar
1/2 c. melted butter

Sprinkle yeast over warm milk; stir to dissolve. Beat egg yolks and add to yeast mixture with vanilla.

Sift together flour, salt, sugar; add to liquid ingredients. Stir in melted butter and combine thoroughly. Beat egg whites stiff; carefully fold into batter.

Let mixture stand in warm place about 45 minutes - sprinkle powdered sugar on waffles.

NOTE: I beat egg whites stiff first and set aside until I mix other ingredients. Saves cleaning beaters for egg whites. May freeze and use individually.
