Gooey Butter Coffeecake recipe

Crust:
1 cup flour
3 tablespoons granulated sugar
1/3 cup butter, softened

Filling:
1 1/4 cups granulated sugar
3/4 cup (1 1/2 sticks) butter, softened
1 egg
1 cup all-purpose flour
2/3 cup evaporated milk
1/4 cup light corn syrup
1 teaspoon vanilla extract

Heat oven to 350 degrees F. Grease a 9-inch square pan.

Prepare crust as you would for a pie pastry to make crumbs which cling together. Press into prepared pan (bottom and up sides ).

For filling, beat sugar and butter until fluffy. Beat in egg. Alternately add and beat in flour, milk, syrup and vanilla. Pour into crust lined pan. Bake about 30 minutes or until cake is almost set (DO not overbake). Cool in pan to room temperature. Sprinkle with sifted confectioners' sugar if desired. Center should have a soft gooey filling.
