Notes
Having your eggs at room temperature to help prevent lumpy batter.
The icing is optional! If you rather not have icing in the morning, you are more than welcome to skip it.
If you like extra streusels, you can definitely double up on the cinnamon streusel ingredients.
To check if the cake is done,insert a toothpick in the center. If it comes out clean or has just a few crumbs, it is done.
To properly measure flour by the scoop, be sure to fluff the flour before spooning it into a measuring cup. This prevents the flour from being packed into a measuring cup. Level the top off inside of trying to pack it all in.
Be sure your oven is fully preheated before adding your cake to the oven.
Do not over mix the cake batter. Over mixing the batter can cause it to become dense.
