A really good portion control cake solution is the Angel food cake mix when paired with another cake mix, and then combined. In a mug, it is 3 tablespoons of mix, along with 2 tablespoons of water, and microwave cooked for one minute on high. I even doubled the ratio of cake mix and water, for one minute, and it did well. The cake mix used was Betty Crocker Supermoist Cherry Chip with pudding baked in (supposedly). It was cake mix that we had around the house. We got the angel food cake mix while we were at Super-Target. I was pleasantly surprised at how good it was. The resulting cake microwaves in a minute. 2 16 ounce cake mixes = 32 ounces. 3 TBSP (tablespoons) = 1.5 ounces. There should be somewhere around 19 servings, maybe. Who knows? I just like the resulting cake mix. That and the fact that it is super easy to fix. I haven’t yet figured out how many calories are in the resulting mixes, but it shouldn’t be that difficult. Cake is happy food. A treat. We used regular coffee cups. It was surprisingly simple.
