Pour batter into greased 8x8 baking dish and bake at 350 for 30-40 minutes or fully browned on top and set in center.

It is difficult to overbake this but easy to underbake.

Carbs: If you divide this into 9 servings, each serving will have 3 carbs and 3 grams of protein according to my personal calculations. Please note that these are my own calculations and I encourage you to calculate the macros for yourself. I am not responsible for errant calculations, ingredient substitutions, etc. It is my policy not to calculate macros on this site so you will rarely see that but from time to time I do share my own calculations. However, it is the responsibility of the individual to track macros for themselves.
