Heat oven to 350°F Grease 11 x 7 inch glass baking dish. Microwave 1/4 cup butter in medium microwave-safe bowl on high 30 seconds or until melted. Stir in brown sugar; microwave 30 to 60 seconds or until sugar is melted and mixture is thick and bubbly. Stir in cinnamon. Pour over bottom of baking dish; top with cherries in single layer.
Whisk flour, nutmeg, baking soda and salt in medium bowl. Beat butter and almond extract in large bowl at medium speed until smooth. Gradually beat in sugar, increase speed to medium-high; beat 4 minutes or until light and fluffy.
Add eggs one at a time, beating well after each addition. At low speed, beat in flour mixture in 3 parts alternately with sour cream just until smooth, beginning and ending with flour mixture. (Batter will be thick.) Spoon and gently spread batter over cherries.
