Preheat oven to 350 degrees.

In a large bowl, whisk together flour, sugar, poppy seeds, baking powder, baking soda and salt, set aside.

Beat eggs in smaller bowl. Add sour cream, butter, lemon peel, lemon juice and vanilla, mix well.

Add to flour mixture, stir just until moistened.

Spoon batter into 12 greased or lined medium muffin cups, filling each cup two-thirds full.

Bake 18 to 20 min. or until toothpick inserted in centers comes out clean. Cool 5 minutes.

Cook's Note: We like to make mini muffins too! Be sure to adjust the cooking time for smaller muffins.
