1 (8 ounce) package lemon flavored yogurt
1 egg
1 tablespoon lemon juice
1 teaspoon lemon zest
1 tablespoon lemon juice
1 teaspoon lemon zest
Preheat oven to 350 degrees F (175 degrees C). Place lemon yogurt and egg in a bowl. Mix well.
In a medium bowl, combine lemon juice, lemon zest and lemon extract. Stir until blended. Pour into the lemon mixture, mixing just until. Pour lemon cream mixture into a small piping bag or similar and pipe lemon cream filling between two greased foil-lined bread pans.
Bake in preheated oven for 20 minutes, or until bubbly and lightly browned. Let cool.
