One 9-inch square coffee cake.

All ingredients at room temperature.

Preheat oven to 350 degrees

Grease a 9 in. square baking pan

Whisk together thoroughly:

1 ½ cups all-purpose flour

1 cup sugar

2 teaspoons baking power

½ teaspoon baking soda

¼ teaspoon salt

In a large bowl, beat well the following:

1 cup sour cream (Sounds crazy, but we’re serious! The cake will be delicious! We promise!)

2 large eggs

Add the dry ingredients & beat until just smooth. Overbeating tends to toughen the cake. Spread in the greased pan.

Sprinkle with Streusel.

Bake until a toothpick comes out clean, about 25 min. Cool on a rack.


Makes 2/3 to 3/4 cup


1/3 cup sugar

2 tablespoons all purpose flour

2 tablespoons unsalted butter

Blend these ingredients until crumbly.


1/2 teaspoon ground cinnamon

(1/4 to 1/2 cup chopped nuts)
