2 eggs
1 cup milk
1/2 cup white sugar
1 tablespoon butter
1 teaspoon vanilla extract
Preheat the oven to 400 degrees F (200 degrees C). Grease muffin cups or line with paper muffin liners.
Beat eggs in large bowl until blended. Stir milk and sugar into egg mixture; beat into egg mixture just until incorporated. Spoon batter into prepared muffin liners.
Bake in preheated oven for 30 minutes, or until a toothpick inserted in center of each muffin comes out clean.
