Bar none--hands down--no question about it--use this doctored Duncan Hines mix. I did a 6 month search for "red velvet". Tried cupcakes from 4 different, famous bakers, tried 5 different recipes. This is the one.

1 Duncan Hines Red Velvet Cake Mix
1 box white chocolate (hard to find, try WalMart) or chocolate instant pudding mix
1/2 c. sour cream
1/2 c. buttermilk
1/3 c. vegetable oil
1 tsp. vanilla extract
BlakesCakes: Hand mix all ingredients until incorporated and then mix on medium with a hand mixer for 1:30 to 2:00 minutes. Bake at 325 until a toothpick comes out clean. The cake is tasty and sturdy. I often ice with a 50/50 mixture of homemade buttercream and canned cream cheese icing so that the cake can stay at room temp for long periods.
