How To Make Irish Oatmeal Cake
Old Fashioned Irish Oatmeal Cake
- In a small mixing bowl, combine the old fashioned oats with boiling water. Allow to sit for 15-20 minutes before making your cake.
- Preheat your oven to 350 degrees F (175 degrees C) and generously coat your 9 x 13 baking pan with butter or non-stick cooking spray.
- In a large mixing bowl, cream together your butter with both white and light brown sugar. Pour your vanilla extract into eggs, mix, then add to the soaked oatmeal and combine.
- Add the baking soda, cinnamon, and nutmeg (plus optional salt) then combine. Add the flour and mix until thoroughly incorporated.
- Add the wet ingredients to your flour mixture and mix just until all of the flour has been incorporated. Transfer to your coated 9 x 13 pan and place on the middle rack of your preheated oven.
- Bake at 350 degrees F (175 degrees C) for 30-35 minutes, or until a toothpick inserted into the middle of your oatmeal cake comes out clean (or with a crumb or two on it, but not wet or ‘gooey’).
- Allow cake to cool in the pan while you make the frosting.
Caramel Pecan Frosting
- In a medium saucepan, melt your butter at medium heat. Add the light brown sugar, sweetened condensed milk, and vanilla. Stir to combine and until all of the brown sugar has melted.
- Whisk frequently while the caramel mixture heats up, then constantly while cooking. Reduce heat as needed to keep your caramel at a low (soft) boil, and just barely bubbling.
- Continue to whisk for 5-10 minutes, or until your caramel has thickened and darkened to a golden light brown caramel coloring. It will be soft, creamy, and still pour-able (although very thick).
- Transfer your caramel mixture to a cool bowl, stir in crushed pecans (reserve some for topping your cake, if desired) and allow to cool 10-15 minutes (but still slightly warm) before spreading over your cake.
- Finish with additional crushed pecans, if desired.
