Old Fashioned Oatmeal Cake

05.11.2018

Happy Mothers Day Weekend! This Oatmeal Cake is the perfect dessert to make for your mom this weekend! It’s an old fashioned style recipe, like a delicious cake your grandma might have made you growing up. It’s an oatmeal based cake, and since they oats are soaked in boiling water it softens them up perfectly so you end with a moist and tender crumb in every bite.

There are many reasons I love this cake. First, like I said, it reminds me of something my grandma would have made. Second, the taste is simply divine – talk about savoring every bite.

And third could cake get any easier? You don’t even need to make a frosting, and bonus that means you don’t have to wait hours for a cake to cool.

    • Jaclyn: The recipe would take quite a bit of tweaking (i.e. a starch would likely need to be added and another egg) so without testing I couldn’t say for sure, sorry! May 13, 2018 at 10:42am Reply
