My Flour Garden's White Chocolate-Covered Red Velvet Cake Balls, originally uploaded by My Flour Garden.
The image pictured here is from My Flour Garden in Southern California. I also found a place in Austin that specializes in cake balls, appropriately called Austin Cake Ball. I'll have to check it out next time I go visit my friends Mo and Jordan.
If you're interested in making said cake balls, Bakerella has a really easy recipe using a mix. I'll be making them soon with a variation on one of my scratch recipes.
