This is the sister recipe to the Basic Chocolate Pound Cake. Also from The Cake Mix Doctor.
1 package plain yellow cake mix
1 package vanilla instant pudding
1 cup whole milk
1 cup vegetable oil
4 large eggs.
Throw everything into your mixer, and beat on low for 1 minute. Stop mixer, scrape down bowl, and beat 2-3 more minutes on medium until batter is thick and well combined. Bake cake at 350 until it starts to pull away from the sides, about 45-50 minutes.
