Preheat your oven to 325F. For best results, I suggest using an oven thermometer.
Line the bottom of an 8” round cake pan with parchment paper, and spray the bottom and sides with non-stick cooking spray.
Beat the eggs in a small bowl and set aside.
Empty the package of protein cake mix into a large bowl.
Once your oven is preheated, add the eggs, oil (or applesauce), and water to the cake mix.
Using a whisk or large fork, mix just until no lumps remain.
Pour batter into the cake pan.
Place cake pan in oven and bake for 28-32 minutes, or until a toothpick inserted in the cake comes out clean.
Let the cake cool for about 10-15 minutes, then run your spatula around the edges of the cake in the pan. Remove the cake from the pan and let it continue cooling on a cooling rack.
Let the cake cool completely if you will top it with frosting. And enjoy!
