Makes 6 servings using a 6-cup Bundt pan.

Cake ingredients:

One package Proteinfull Baking Classic Yellow Cake Mix
3 large eggs, beaten (there is an egg-white sub on the package)
3 tablespoons oil or unsweetened applesauce
⅔ cup water

    Icing ingredients:

    ½ cup confectioners erythritol
    1 teaspoon lemon zest (zest of one small lemon)
    2½ tablespoons water (add gradually, you may need slightly more or less)


    1. Preheat oven to 325˚F.
    2. Combine cake mix with eggs, oil (or applesauce), and water. Mix just until no lumps remain.
    3. Spray 6-cup bundt pan with non-stick cooking spray. Spray generously, but not so much that there are pools of oil on the bottom.
    4. Bake for 28-32 minutes, just until the cake is fully cooked and the top is firm (and a toothpick comes out clean).
    5. Let cool for about 10 minutes. Then use a narrow silicone spatula to separate the cake from the pan, and turn the cake onto a plate.
    6. Let the cake cool completely.
    7. Make the icing by mixing the confectioners erythritol, lemon zest, and 2 tablespoons water to start. Mix well, and see if you need the other ½ tablespoon water (or more) to get the thickness you desire.
    8. Drizzle icing on cool cake, and enjoy! Store refrigerated.
