I have this in the oven baking right now. Taking it to Easter breakfast at church Looks good. I added brown sugar to the topping!
1 cup butter (no substitutes)
1 cup sugar
1/4 cup sour cream
2 cups flour
2 teaspoons baking powder
1/2 teaspoon salt
2 (8 ounce) packages cream cheese, softened
1 egg yolk
1 cup sugar
1 teaspoon vanilla
1/4 cup sugar
1/2 cup flour
1/4 cup butter (semi-soft)
1Set oven to 350 degrees (oven rack set to second-lowest position).
2Grease a 13 x 9-inch (or an 11 x 7-inch, baking time will need to be increased slightly).
3Cream butter with sugar (about 3-4 minutes), add in eggs and sour cream; beat well (about another 3 minutes).
4In a bowl, sift together flour, baking powder and salt.
5Add the flour mixture to the creamed mixture; beat well until combined (batter will be thick).
6Spread more than half of the batter in the prepared baking pan.
7In another bowl, cream together all filling ingredients, then carefully spread over the cake batter.
8Spoon the remaining cake batter over the top of the cheese mixture (it doesn't have to cover the cake batter completely, I just dot tablespoonfuls over the batter).
9For the topping (I most always double the ingredients) mix all ingredients, and sprinkle over cake.
10Bake for about 50-55 minutes or until middle feels set and not jiggly.
