Preheat oven to 350 degrees.
Butter a 9×13 baking dish.
Mix together the dry ingredients in one bowl. Mix thoroughly.
Mix the moist ingredients in a second bowl. Mix thoroughly. Remember it is important that these ingredients be at room temperature.
Pour into butter baking dish and place in heated oven.
Bake for about 40 minutes. Pay attention to what your nose is telling you. Your cake could finish sooner than this. Use a toothpick to check for doneness. If the toothpick has batter clinging to it, keep baking.
Cool and enjoy. This freezes well and is a pleasant addition to the lunch box.
