Apple Coffee cake

Ingredients
Topping
3 medium apples, sliced thin (I used Granny Smith)
1 tablespoon fresh lemon juice
1/3 cup sugar (white or brown)
3/4 teaspoon cinnamon
Cake
1 1/2 cups flour
1 1/2 teaspoons baking powder
3/4 teaspoon salt
1/3 cup butter (or shortening)
1 cup white sugar
2 eggs
1 cup sour cream
1/2 teaspoon baking soda
Directions
1Topping.
2It is not necessary to peel the apples, but I do.
3Combine the sliced apples,lemon juice,sugar and cinnamon in a small bowl and set aside.
4Combine dry ingredients - flour,baking powder and salt in a bowl, set aside.
5In a large bowl cream butter, add sugar gradually, beat well.
6Beat eggs into creamed mixture.
7Measure sour cream into a separate bowl, add baking soda, stir together; the cream will rise up and become fluffy.
8Add sour cream to the batter alternately with the dry ingredients. Blend well.
9Pour half the batter into a greased and floured 9" square cake pan, top with half the apple mixture.
10Add remaining batter and arrange rest of the apples on top.
11Bake in 325 degree oven for 50-60 minutes.
12Especially nice served warm. Enjoy!
