"These moist, buttery muffins with their nutty topping are so easy to make," assures Dena Engelland from Sterling, Kansas. Stir up a batch of the cute cakes and let them bake alongside the frittata while you fix the rest of the meal."
In a large bowl, cream butter and sugar until light and fluffy. Beat in egg. Combine the flour, pudding mix, baking powder and salt; gradually add to the creamed mixture alternately with milk, beating well after each addition. Stir in walnuts.
Fill paper-lined muffin cups two-thirds full. Combine topping ingredients; sprinkle over batter. Bake at 375° for 20-25 minutes or until a toothpick inserted in the center comes out clean. Cool for 10 minutes; remove from pan to a wire rack.
