Coconut Yellow Cake

I found this simple coconut cake recipe in a magazine while in the dentist's office waiting room some months ago. This recipe uses basic simple yellow cake mix from the box or all-purpose flour mix with baking powder, and baking soda helps the cake rise. This cake can be whipped up quickly for last-minute occasions.
Ingredients:
1 1/2 cups flour
1 tsp baking powder
1/2 tsp baking soda
1/4 tsp salt
3/4 cup buttermilk
3 eggs
1 cup sugar
1 tsp vanilla
1/2 cup soft margarine, oil or butter
1/2 cup sweet shredded coconut + 1/4 cup for topping

Directions:
Preheat oven to 350°. Lightly grease a 9" x 5" cake pan. Line with parchment paper. Grease the paper with oil and dust with flour. Set aside

Sift flour, baking soda, baking powder and salt. Set aside

Place butter and sugar in the mixer bowl. Using the paddle attachment, cream (beat) the mixture on medium speed until fluffy (about 2 to 3 minutes)

. Scrape down the sides of the mixer bowl. Add eggs one at a time. Continue until the mixture increases in volume. Turn the mixer to low speed. Add the flour in 3 batches, alternating with buttermilk and ending with the flour. Add vanilla. Do not overmix.

 Fold in the shredded coconut. Pour the batter into the prepared baking pan.

 Top with 1/4 cup of coconut and bake in preheated oven for 30 minute or until the cake is golden brown or by using the cake test, which is when a toothpick inserted into the center of the cake comes out clean.
