This is all you need + 1&1/4 cups of water:
I typically go the old fashion route for the easy stir baking by using a whisk. Only stir until mixed, it will be watery and foamy.
I let my batter sit for just a few minutes to let it fluff up before putting it into the middle rack of the oven. The cake will rise within minutes and then continue to bake. Once the cake is done, turn upside down on a cooling rack. Once cool, pull cake carefully out of the pan and place on a cake serving platter. I typically serve with thawed sliced strawberries which can be found in the freezer isle near the ice cream.
