Raisin Oatmeal Sheet Cake

This Raisin Oatmeal Sheet Cake is a family favourite recipe that I have been making for many years now.  It’s my go to comfort cake that we like to enjoy as a breakfast or snack cake.  

But I think what I love the most about this cake, aside from how delicious it is, is the fact that the ingredients are simple and I almost always have them in my pantry.  That, and you can have it assembled and baking in the oven in no time…it’s just an uncomplicated and delicious cake.  The simplicity of this cake actually makes me wonder if generations before us have been passing a similar recipe down to their families.  It just reminds me of a cake that you would find the recipe for in old community church cookbooks.

I have a soft spot for this cake, that’s for sure.

Raisin Oatmeal Sheet Cake {A Pretty Life}

This Raisin Oatmeal Sheet Cake is moist, cinnamon-y and oat-y.  Those are totally words, right?  Oh, and have I talked about the icing yet?  The gooey toasted brown sugar and coconut icing?  Well, let’s just say it’s the icing on the cake…the perfect topping for this delicious oatmeal sheet cake.

  • Reply Grísel Salazar August 3, 2015 at 4:15 PM Hi, from Mexico! I was wondering if you added the oatmeal with or without the water.
    • Reply Jo-Anna@APrettyLife August 21, 2015 at 2:31 PM Hi Grisel! You have to add the oats to the hot water and let them sit for at least 5 minutes before adding them to the rest of the ingredients. Happy baking!
