In a large saucepan, combine cornstarch and strawberries until blended. Bring to a boil over medium heat or until thickened. Remove from the heat. Stir in cinnamon and almond extract; set aside.
In a large bowl, combine flour and sugar. Cut in butter until mixture is crumbly. Set aside 1/2 cup for topping. Add baking powder, baking soda and salt to the remaining flour mixture. Stir in buttermilk and egg until moistened.
Spread 1-1/2 cups of batter into a greased 8-in. square baking dish. Carefully spread with the strawberry mixture. Drop remaining batter by tablespoonfuls over strawberry mixture. Sprinkle with reserved crumb mixture. Bake at 350° for 35-40 minutes or until golden brown. Cool on a wire rack.
