Preheat oven to 350º. Mix the cake mix, buttermilk, oil, eggs and vanilla in a large mixing bowl on low speed for one minute until combined. Beat at medium speed for two minutes more.
Pour into two greased and floured 9 inch round pans. Bake for 30 - 35 minutes. Cool on a wire rack for 10 minutes and remove from pans. I like to line my round cake pans with parchment paper before adding batter for easy removal from the pan
You can also baked the cake in a greased and floured 13 x 9 baking dish. Bake 38–42 minutes until the cake springs back when lightly pressed. Allow to cool completely on a wire rack before frosting.
Coconut-Almond Frosting
Combined butter, sugar, evaporated milk and eggs* in a saucepan. Cook over medium heat, stirring constantly, for about 12 minutes or until thickened. Add vanilla, coconut and almonds. Cool to room temperature before frosting cake.

Notes
*You can also warm up the butter, sugar and evaporated milk and temper the eggs before adding them to the saucepan.Chocolate drizzle, optional - I just melted about ¼ cup of chocolate chips, put it in a Ziploc storage bag, snipped the corner and drizzled a bit on top.
