Ingredients

  • 1/2 cup butter, softened
  • 1 cup sugar
  • 2 large eggs, room temperature
  • 1 cup plain yogurt
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour

Method

  • In a large bowl, cream butter and sugar until light and fluffy. Add eggs, one at a time, beating well after each addition. Beat in yogurt and vanilla. Combine the flour, baking soda, baking powder and salt; add to the creamed mixture just until moistened. Fold in chocolate chips. Fill 12 paper-lined muffin cups two-thirds full.
