In small saucepan over medium heat, whisk 1/2 cup granulated sugar, 1/2 cup orange juice, 1 tablespoon orange zest, and 1/3 cup water. Bring to simmer, whisking to dissolve sugar. Cool syrup to room temperature.
Meanwhile, in a small bowl, mix almond flour, all-purpose flour, and cornstarch. In a medium bowl, using an electric hand mixer, beat 1/2 cup granulated sugar and butter for 3 minutes, or until light and fluffy. Add egg and almond extract and beat until blended. Add flour mixture and beat until just blended.
