Lemon Raspberry Jumbo Muffins Recipe

In a large bowl, cream butter and sugar until light and fluffy. Add eggs, one at a time, beating well after each addition. Stir in buttermilk and vanilla. Combine the flour, baking powder, baking soda and salt; add to creamed mixture just until moistened. Fold in raspberries and lemon peel. Fill paper-lined jumbo muffin cups half full. Bake at 350° for 23-28 minutes or until a toothpick comes out clean. Cool for 5 minutes before removing from pan to a wire rack. Combine glaze ingredients; drizzle over warm muffins. Yield: 1 dozen.
