Diabetic Mango Coffee Cake

Preheat oven to 375 degrees F. Lightly coat a 9 x 1-1/2-inch round baking pan with nonstick cooking spray; set aside. Seed, peel, and chop one of the mangoes; set aside. Seed, peel, and slice the remaining mango; set aside.

In a large bowl, stir together sugar and oil. Add milk and egg. Beat with an electric mixer on medium speed for 1 minute.

In a small bowl, combine all-purpose flour, whole-wheat flour, baking powder, lime peel, and cardamom or allspice. Add to beaten mixture; beat until combined. Stir in oats and chopped mango. Spoon into prepared pan. Arrange sliced mango over batter.

Bake for 35 to 40 minutes or until a toothpick inserted near the center of the cake portion comes out clean. Cool in pan on a wire rack for 30 minutes. Serve warm.
