Grease a 9 inch square pan. Line with foil. Preheat the oven to 350 degrees.
In a medium bowl, combine peaches, blackberries, 1/4 c. sugar, lemon juice, and almond extract. Set aside. Beat together softened butter and sugar until light and fluffy. Add flour, baking powder, and salt until crumbly. Slowly pour in milk and stir until incorporated then beat until batter is smooth. Place fruit mixture at the bottom of the pan.
