Preheat oven to 350°. Spray a 13×9-inch baking pan with baking spray with flour.
In a large bowl, whisk together flour, granulated sugar, baking powder, cinnamon, baking soda, and salt. Make a well in center of flour mixture. Add melted butter, sour cream, milk, eggs, and extracts. Whisk together just until combined. (Batter may have a few lumps.) Pour batter into prepared pan, smoothing to edges and corners. Drop jam by teaspoonfuls over batter; gently swirl using the tip of a knife. Sprinkle with slivered almonds.
Bake until a wooden pick inserted in the center comes out with a few moist crumbs, 28 to 30 minutes. Let cool completely in pan. Garnish with confectioners’ sugar, if desired.
