Traditional Chocolate Chip Muffins

Directions

1. 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.
2. Combine the topping ingredients; sprinkle over batter. Bake at 350° for 25-30 minutes or until a toothpick inserted in the center comes out clean. Cool for 5 minutes before removing from pan to wire rack. Serve warm.
