You can use many different fruits for this coffee cake. I used blueberries because I grow them and we had plenty.
You will need an 8" square pan.
Preheat your oven to 350 degrees Fahrenheit.
1-1/2 cups chopped, peeled apple, apricots, peaches or pineapple; you can also use 1-1/2 cups blueberries or raspberries
1/4 cup water
1/4 cup sugar
2 Tablespoons cornstarch
1-1/2 cups flour
3/4 cup sugar1/2 teaspoon baking powder
1/4 teaspoon baking soda
1/4 cup butter
1/2 cup buttermilk
1/2 teaspoon vanilla
1/4 cup flour
1/4 cup sugar
2 Tablespoons butter
In a saucepan, combine the fruit and water. Bring to a boil and reduce heat.
Simmer for 5 minutes, unless you are using the raspberries. Do not simmer those-they fall apart.
Combine the 1/4 cup sugar and the cornstarch and stir into the fruit.
Cook and stir over medium heat until mixture is thick and bubbly.
Cook and stir 2 more minutes.
Remove from heat.
In a bowl, combine the 1-1/2 cups flour, 3/4 cup sugar, baking powder, and baking soda.
Cut in the butter til you have coarse crumbs.
In another bowl, beat the egg, buttermilk, and vanilla extract.
Add that mixture to the flour mixture and stir just until moistened.
Spread half the batter into baking pan.
Spread fruit mixture over that.
Drop remaining batter in mounds atop the fruit filling.
Mix together the remaining sugar and flour. Cut in the 2 Tablespoons butter til you have coarse crumbs.
Sprinkle that over the coffee cake.
Bake for 40-45 minutes until golden.
