Kittencal's 5-Minute Cinnamon Flop Brunch Cake

"Except for the the milk and small amount in the egg, the cake itself has very little fat and using low-fat milk will keep the fat to a minimum, I have stated the egg as optional, I strongly suggest to add it in for a more cake-like texture -- If you are looking for a fancy cake to serve then this is not it however for the ease of this cake it is darn good and makes a great weekend brunch cake, it's like a combination of a cake and cinnamon bun all in one, ridiculously simple to make as it's all mixed by hand and takes like 5 minutes to throw together, try adding in some chopped strawberries, apples or blueberries, raisins or dried cranberries, this recipe is a blank canvas, so go ahead and add in fruit, nuts chocolate chips whatever you wish, and to kick this up a notch drizzle Kittencal's Easy Creamy White Glaze on top :) --- servings are only estimated..."
