Struesel Cake

I have to give credit to Emily Johansson for this recipe. She prepared this cake for us on Conference Sunday when we were freshman roommates. Our family has since adopted this tradition, and my husband always looks forward to warm struesel cake for General Conference.
Struesel Cake
3/4 cup sugar
1/4 cup shortening
1 egg
3/4 cup milk
1 1/2 cup flour
1 tablespoon baking powder
1/4 teaspoon salt

Struesel
1/2 cup packed brown sugar
2 teaspoons cinnamon
2 tablespoons flour
2 tablespoons melted butter

Beat sugar and shortening. Add beaten egg. Stir in milk; then add flour, powder, and salt. Put half of the batter in a greased 9 x 9 pan, cover with half of the struesel topping, and then repeat. Bake at 375 degrees for 25-30 minutes.
