Baby It’s Cold Outside. Warm Up With My Old Fashion, Brown Sugar Oatmeal Cake!

on Feb 28, 2015 |





I love hot cinnamon oatmeal on a cold night. And yes, even though I live in Orlando, it gets cold here. There is nothing more warming to my heart than a warm cinnamon spice cake. But let’s take that one step further and mix in some oatmeal to make it hearty and dense….Then I am going to blow your mind by topping this old fashioned cake with some homemade toasted marshmallow frosting.

This recipe is old school, but I have tweaked and updated the ingredients to my liking. It is a unique cake with a large dense crumb and you can actually see the oatmeal throughout this sweet baby. Once you make it your tastebuds will be begging you for more on a weekly basis. And since it has oatmeal in the batter, it is technically breakfast. So, eating this cake at all hours of the day is acceptable in my book.

My little ladies adore this homemade marshmallow frosting. Now it is made on the stovetop, so they are not able to assist as much as usual. But as soon as this stuff is cool, they are up for licking the beaters, spoons, and dipping their fingers in the bowl. I am SO guilty of that myself!
