The instructions on the mix are for the full packet (2 servings). So you'll add 90g applesauce and 2 tablespoons water to the full packet of cake mix. (Or 1/2 can diet soda to the full packet of mix.)

You can find applesauce pouches here on Amazon: Applesauce pouches

Many large grocery chains also sell them.

Other fruit and vegetable mashes will work! (Pumpkin, banana, etc.)

Keep in mind that you may want to add a little extra water or lessen the bake time if using something more thick than applesauce.

Also, the (unsweetened) applesauce does add sweetness to the cake. If you use a less sweet substitute, you may want to add some sweetener of your choice. 

For a lower carb option, you can omit the applesauce and water, and prepare the cake mix with 1/2 can (6 fl.oz) diet soda or seltzer. We recommend natural stevia-sweetened cream soda.

For traditional cake texture and shape, bake in the oven. For a super-quick snack, you'll still get pretty good results from the microwave! See below for oven and microwave tips.

To keep the protein cake from getting dry, it is important not to overbake the cake. It may be worth checking your oven temperature with an oven thermometer.

If your oven doesn't heat consistently throughout, you may want to rotate your cake pan halfway through the bake time.

The bake time listed on the package says to check after 15 minutes for 4 cupcakes or a 5"-6" cake. The actual bake time will depend on the bakeware you use and your oven temperature. Because overbaked protein cake will be dry, you might want to check your oven temperature with an oven thermometer

Also keep in mind that if you are using very cold ingredients, that could affect the bake time, as well.

Recommended bake times:

- Our silicone cake pan ~ 15 -18 minutes

- Cupcakes in silicone liners ~ 18 - 20 minutes

- 2 packets cake mix (prepared) in our silicone cake pan ~ 20 - 25 minutes

- Mini donut pan ~ 12 minutes

We like to bake in silicone bakeware because it's convenient (doesn't stick, easy to clean) and doesn't conduct heat (less chance of overbaking).

Other bakeware choices will also work (glass, dark non-stick), but the bake times may be less than what we recommend for silicone. Also be sure to spray these with non-stick cooking spray first.

The cake batter will inflate and deflate as it bakes in the microwave. So unless you want a cake volcano to clean up, be sure your cake batter fills the container at most halfway. Do not try microwaving cupcakes!

For the full packet of mix (prepared) in our silicone cake pan, we suggest 2 minutes for a 1000 watt microwave. If your wattage is lower, you may need more time. If your wattage is higher, you'll need less time. It's always better to start with a lower time so your cake does not get overcooked and dry out. Also keep in mind that if you are using very cold ingredients vs. room temperature ingredients, that could affect the bake time, as well.

Our silicone cake pan is the perfect size to bake or microwave your cake. In the oven, it will make a thin cake perfect for layering (or you can use two packets of prepared mix for a thicker cake!). In the microwave, only one packet of prepared mix will fit, as the cake will inflate and deflate as it bakes.

It is not necessary to spray the silicone pan with cooking spray before use. To save time and cleaning effort, you can mix the batter directly in the pan, if desired!

16oz microwave-safe mug for one serving. See below for mug cake instructions.

To prepare 1 serving of cake in a mug:

Mix 1/2 packet cake mix + 3 tablespons applesauce + 1 tablespoon water in a mug that holds at least 16oz. Microwave for about a minute (1000 watt microwave). The cake will inflate and deflate as it bakes, so make sure your mug is big enough to allow for this! And it's always better to start with a lower microwave time so your cake does not get overcooked and dry out.

We've included a mug cake photo on the vanilla cake mix page.

Our cake mixes contain 1g or less of sugar from lactose per serving, and do not contain casein protein. Some protein shake powders contain digestive enzymes as a supplemental aid, but digestive enzymes are known to be rendered inactive under heat (this is the basis of the raw food movement). For this reason it wouldn't make sense to add digestive enzymes to cake mix. If you would like to supplement our cakes with digestive enzymes, we suggest taking a supplement separately.

We use erythritol (and stevia) to sweeten our cake mixes. Erythritol is a natural sugar alcohol, but it does not generally cause the digestive distress common to other sugar alcohols.
