Oatmeal Cake Ingredients

How To Make This Oatmeal Cake Recipe

For the Cake

STEP ONE: Put the oats into a small bowl and pour the boiling water over the oats. Cover the bowl and leave the oat mixture to stand for 20 minutes so they swell and thicken.

STEP TWO: While the oats are in the hot water soaking, in a large bowl with an electric mixer at medium speed, cream together the shortening, white sugar, and brown sugar. Then mix in the eggs, flour, salt, nutmeg, baking soda, and cinnamon.

STEP THREE: Once all the ingredients are combined, uncover your oatmeal mixture and mix all the ingredients together in a bowl.

STEP FOUR: Transfer the cake batter to a large greased 9 × 13-inch pan and bake at 325°F for 40 to 45 minutes.

For the Frosting

STEP ONE: To make the oatmeal cake frosting, you need to cook the milk and flour in a saucepan over the stove on low heat until the mixture becomes thick.

STEP TWO: Once the milk and flour thicken, remove it from the stove and leave it to cool. Cream together the sugar, margarine, and shortening.

STEP THREE: Once the milk and flour mixture has cooled, beat together with the creamed sugar, margarine, shortening, and 1 teaspoon of vanilla.

STEP FOUR: When the cake has cooled, generously spread the oatmeal cake frosting over the top of the cake. All that’s left to do is cut into portions, serve and enjoy.
