Autumn Apple Cake

So I was browsing through my first issue of Cooking Light and came across this recipe. I was so glad I had everything I needed to make this. I realize the ingredients aren't that much to ask to have on hand, but I actually had a Pink Lady apple AND golden raisins. Awesome. The best thing was that I actually wanted to bake something today, but wasn't sure what...this fit the bill. It's yummy!

Cooking spray
1 tablespoon all-purpose flour
6.75 ounces all-purpose flour (about 1 1/2 cups)
2 teaspoons baking powder
1/4 teaspoon salt
1/4 teaspoon ground cinnamon
3/4 cup granulated sugar
5 tablespoons butter, softened
1 teaspoon vanilla extract
1 large egg
1/2 cup 2% reduced-fat milk
1 cup finely chopped peeled Pink Lady apple (about 1 medium)
1/2 cup golden raisins
1/4 cup finely chopped walnuts - I didn't use them since we're not really fans of nuts in our desserts
1 teaspoon powdered sugar

Preheat oven to 350°. Coat a 9-inch round cake pan with cooking spray, and dust with 1 tablespoon flour. Weigh or lightly spoon 6.75 ounces flour into dry measuring cups; level with a knife. Combine 6.75 ounces flour, baking powder, salt, and cinnamon in a small bowl, stirring with a whisk. Place granulated sugar and butter in a large bowl; beat with a mixer until well blended. Beat in vanilla and egg. Beat in flour mixture alternately with milk, beginning and ending with flour mixture. Fold in apple and raisins. Scrape batter into prepared pan. Bake at 350° for 30 minutes or until a wooden pick inserted in center comes out clean. Cool 10 minutes in pan on a wire rack. Remove from pan; cool completely on wire rack. Sift powdered sugar over cake. Cut into wedges.
