1 lb. cream cheese
1 egg yolk
1 tsp. minced instant onion
1 tsp. baking powder
2 1/2 tbsp. imitation bacon pieces
40 Ritz crackers

Combine cream cheese, egg yolk and onion in a large bowl. Blend until smooth. Stir in baking powder and bacon pieces and blend. The mixture may be covered and is ready to use when you are ready at this point. Mound 1 tablespoon on each cracker. Heat oven to 350 degrees. Bake 9 minutes or until cheese is puffed and lightly brown on top.
