I won a Grand Champion Ribbon at the Austin County Fair in Texas with this recipe. I garnished with orange slices around bottom of cake and orange zest on top for the contest. This is a truly good cake.
Preheat oven to 350. Generously grease and flour Bundt pan. Blend all ingredients in a large bowl; beat at medium speed for 2 minutes. Bake at 350. Cake is done when toothpick inserted in center comes out clean. (So not test by touching with finger. Crust will be darker than regular layer cake.)
Cool in pan 25 minutes, then invert onto serving plate. Cool. Glaze when completely cool.
Glaze: Place 2/3 cup Duncan Hines Vanilla frosting into small saucepan. Heat over medium heat, stirring constantly. Add flavoring and orange zest. Stir until well mixed. Pour glaze over cooled cake.
