Preheat oven to 350°. In a large bowl, beat the eggs, sugar and brown sugar for 3 minutes. Add butter and extracts; mix well. Combine the flour, baking powder and salt. Gradually add to the creamed mixture, beating just until blended. Fold in almonds.
Pour into an 8-in. square baking pan coated with cooking spray. Bake until a toothpick inserted in the center comes out clean, 25-30 minutes. Cool on a wire rack. Cut into squares.
