Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  • Pour the boiling water over the rolled oats in a bowl. Set aside to let the oats absorb the water for about 20 minutes.
  • In a medium bowl, whisk together the flour, baking soda, baking powder, ground cinnamon, and salt. Set aside.
  • In a large mixing bowl, cream the softened butter with granulated sugar and brown sugar until the mixture becomes light and fluffy.
  • Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  • Gradually mix in the buttermilk and the oat mixture until well combined.
  • Slowly add the dry ingredients into the wet mixture, stirring until just combined. Be careful not to overmix.

Baking

  • Pour the batter evenly into the prepared cake pans.
  • Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
  • Once baked, let the cakes cool in the pans for about 10 minutes before transferring them to wire racks to cool completely.

Filling Assembly

  • For the filling, whip together the powdered sugar, milk, and vanilla extract until you achieve a smooth and spreadable consistency.
  • Once the cakes are cool, spread the filling over the top of one cake layer. Place the second layer on top and spread more filling on the top.
  • You can also add extra filling between layers if desired, or spread some on the sides of the cake.
