Cheesy Potato Casserole
This easy cheesy potato casserole recipe was given to me by my mother-in-law. I have modified it slightly to include a crispy topping. It is a must have for my family's Easter dinner.
Apple Bread with Double Streusel
This apple strudel bread is the most delicious bread I have ever tasted. It is so unique because it has streusel on both the top and the bottom. The apples are shredded, which makes the bread very moist. Be prepared because everyone will ask you for the recipe!
Philly Fluff Cake
This cake is very popular in the East Coast. Natale's Bakery in New Jersey is famous for this cake. I made a small cake but this recipe can be easily doubled and baked in a 12 cup tube or Bundt pan. The powdered sugar is a must on this cake.
