This is a chocolate cake with an addition I would not have thought of on my own. I was at a friend's house with a few other ladies and we were quilting. For a treat one of the ladies brought a bundt cake that she had made that started with a yellow cake mix. It had blueberries and yogurt and it was really good. I asked for the recipe which she was able to tell me right on the spot. A couple days later I decided I wanted to give it a try, but I didn't have any vanilla yogurt on hand and I only had a Devil's Food chocolate cake mix. My husband thought it would be good to try using the chocolate cake mix. After all he does like his chocolate. The only ingredient I changed was the chocolate cake mix.... everything else was just as the original list that was given to me. So here is the recipe and it was awesome.
Chocolate Blueberry Cake
1 package Devil's Food cake mix (yellow cake mix)
1 package Instant Vanilla pudding
1 teaspoon cinnamon
1 cup vanilla yogurt
1/2 cup oil
1/4 cup water
1 1/2 cups blueberries (if frozen they should be thawed)
Combine dry ingredients in a large mixing bowl. Reserve a couple tablespoons of the dry ingredients to coat the blueberries before adding. Whisk the eggs with the oil, water and yogurt. Pour the liquid into the dry and mix with an electric mixer until well blended. In a separate smaller bowl coat the blueberries with the reserved dry mix. This will help keep the blueberries from sinking to the bottom of the cake. Fold in the blueberries.
Lightly grease and flour a bundt pan. Pour mixture into pan and bake at 350 for 1 hour.
