Tasty Tuesday: Old Fashioned Oatmeal Cake

Some recipes stand the test of time. This simple, rich recipe for homemade Oatmeal Cake comes from my friend, Lori, who got it from her mother-in-law. Lori is pretty sure that her mother-in-law got it from HER mother… When a recipe gets passed down for a couple of generations, you KNOW that it’s a good one. (I also know that every recipe I’ve ever gotten from Lori has been stellar, so this seemed like a really good bet!) When I got a bite of this delicious cake, I knew it was destined to become one of OUR family favorites!

This recipe doesn’t require any special ingredients; all the ingredients are staples that I always have on hand. I had everything in my cupboard and fridge already. The longer I cook and bake, the more I love knowing the name of every single ingredient in a delicious piece of food. In fact, I’ve become downright distrustful of long ingredient lists on prepackaged foods. But that’s a different conversation for a different day.
At any rate, this recipe is very basic and simple in terms of ingredients, but don’t be fooled. This cake is rich! You’ll want to cut it into small pieces. (And this is one of those cakes where the corner pieces are the VERY best!)

  • 1 c. oats

  • 1 c. brown sugar
  • 1 c. white sugar
  • 1 c. butter
  • 2 eggs
  • 1 t. baking soda
  • 1 t. salt
  • 1 1/2 c.s flour
  • 6 T. melted butter
  • 1 c. brown sugar
  • 4 T. heavy cream
  • 1/2 c. chopped nuts (I used chopped almonds because those are my favorite. Walnuts would also be a great choice for this frosting.)

    Add boiling water to the oatmeal and let them get acquainted.

  3. Bake in a 9×13 pan for 30 minutes at 350° or until the cake is just done. (In my oven, that took about 35 minutes.)
  4. Mix together ingredients for the frosting while the cake is baking.
  5. Remove pan from oven, GENTLY spread frosting over warm cake. (It’s easiest to do this by spooning out dollops of the frosting across the hot cake. Then spread the melting frosting to cover the entire cake.)Old Fashioned Oatmeal Cake
  6. Bake another 5-7 minutes.
This cake is so rich and buttery and delicious. It really does taste like the kind of cake that my grandma or any of her friends might have made back when I was a little kid.

It’s not too soon to check out Stick Boy Bread’s Irish Soda Bread if you’re planning to celebrate St. Patrick’s Day with some traditional Irish foods. Stick Boy has super delicious Irish Soda Bread.

  1. Yum. I think I’ll do this this week. My family doesn’t have enough dessert in their lives. I get so caught up in just feeding them that I forget that part. 🙁
