If you don’t have buttermilk, clabbered or soured milk can be substituted. To make sour milk mix 1/2 tablespoon lemon juice with 1/2 cup of milk and let sit for 10 minutes. White vinegar can also be substituted for lemon juice, but I find lemon juice tastes better.
1 1/2 to 2 cups sliced, peeled apricots or peaches; chopped, peeled apples; chopped pineapple; pitted cherries; blueberries, blackberries or red raspberries
1/4 cup water
1/4 cup sugar
2 tablespoons cornstarch
1 1/2 cups all-purpose flour
3/4 cup sugar
1/2 teaspoon baking powder
1/4 teaspoon baking soda
1/4 cup (4 tablespoons) salted butter
1 egg, beaten
1/2 cup buttermilk or sour milk *
1/2 teaspoon vanilla
1/4 cup all-purpose flour
1/4 cup sugar
2 tablespoons salted butter
For apricot/peach/apple/pineapple/cherry/blueberry filling – combine prepared fruit and water. Bring to a boil; reduce heat, cover and simmer for 5 minutes or until fruit is tender. Combine sugar and cornstarch; stir into fruit. Cook and stir over medium heat until mixture is thicken and bubbly, about 3 to 5 minutes. Set filling aside.
For blackberry/red raspberry filling – Combine fruit, water, sugar and cornstarch. Cook and stir over medium heat until mixture is thicken and bubbly, about 5 to 7 minutes. Set filling aside.
For cake, pre-heat oven to 350-degrees.
In a medium bowl combine flour, sugar, baking powder and baking soda. Cut in butter, until mixture looks like coarse crumbs. Make a well in center of flour mixture; set aside. In another small bowl, mix egg, buttermilk and vanilla; pour into flour mixture. stir with wooden spoon until just moistened – the batter will be slightly lumpy. Spread half the batter into an un-greased 8x8x2-inch square baking pan. Spread fruit filling over batter. Drop remaining batter in small mounds on top of fruit filling. Set aside.
For crumb topping, mix flour and sugar in a small bowl. Cut in butter until mixture looks like coarse crumbs. Sprinkle over coffee cake.
Bake in 350-degree oven for 40-45 minutes or until golden brown. If using a glass pan, I recommend dropping your oven temperature down to 325-degrees.
Serve warm. Store covered tightly with plastic wrap for up to two days.
