Klean Double Chocolate Cake

It’s not often that you find a double chocolate cake infused with 6 grams of protein, 3 grams of fiber and over 12% of your Daily Value for vitamin C. As you can see from the ingredients, this cake is oil-and butter-free so it relies on pureed prunes and applesauce to impart moisture and a delicate mouthfeel. No icing required. A sprinkle of chocolate chips on top will keep it Klean, but don’t resist a dollop of low fat whipped topping, especially after an intense workout. Actually, a serving of this cake with a glass of low fat milk is a perfect recovery snack when consumed within 30 to 60 minutes of a tough training session or competition.


YIELD: 15 servings



  • 2 cups old fashioned oats, blended to flour in a food processor or blender
  • 1 cup white whole wheat flour
  • ¼ cup unsweetened cocoa powder
  • ½ cup Klean Isolate™ Whey Protein
  • 2 tablespoons flax meal
  • 1 teaspoon baking soda
  • ½ teaspoon sea or table salt


  • ¾ cup dried, pitted prunes
  • 3 tablespoons water
  • 1-1 ⅓ cups unsweetened applesauce
  • 1 teaspoon vanilla
  • ½ cup semisweet or special dark mini (or regular) chocolate chips


  • ~¼ cup semisweet or special dark mini (or regular) chocolate chips and/or chopped nuts
  • Fat free whipped topping


  1. Preheat the oven to 350°F. Spray one 9” x 9” cake pan with cooking spray.
  2. Dry Ingredients: Blend the old-fashioned oats in a food processor or blender until they resemble flour. Mix together oat flour, white whole wheat flour, cocoa powder, Klean Isolate™, flax meal, baking soda and salt in a large bowl.
  3. Wet Ingredients: Blend together the prunes, water, applesauce and vanilla in a food processor or high-powdered blender.
  4. Slowly integrate the wet ingredients into the dry ingredients. Mix only until the dry and wet ingredients are incorporated. Add ½ cup of chocolate chips to the batter. Stir sparingly until the chocolate chips are distributed throughout the batter.
  5. Pour/press the batter into the greased 9” x 9” cake pan.
  6. Sprinkle ~ ¼ cup of chocolate chips and/or chopped nuts on the top of the batter.
  7. Bake at 350°F for 30-40 minutes. This cake is thick and cooking time will vary a bit depending on your oven. Be sure not to overcook or it will lose its delicate moistness.
  8. Remove from the oven and let chill for 15 minutes before diving in.
