  • 1 tbsp + 1 tsp ground cinnamon
  • 1 teaspoon fine sea salt

Instructions

  1. Cook the oats by combining water and quick-cook oats over medium heat, stirring occasionally, until tender. Let cool.

  3. Mix the dry ingredients: whisk flour, cinnamon, salt, nutmeg, and baking soda in a large bowl.
  4. Cream butter and sugars until light and fluffy, about 3–5 minutes.
  5. Add vanilla and eggs one at a time, mixing well after each.
  6. Combine the dry ingredients with the butter mixture, alternating with oats and sour cream until just combined.
  7. Bake the batter in the prepared pans for 25-30 minutes or until a toothpick comes out clean.
  8. Make the frosting by beating butter, then gradually adding powdered sugar, followed by heavy cream, vanilla extract, and vanilla bean paste until fluffy.
  9. Assemble the cake by layering cooled cakes with frosting in between; cover the whole cake with frosting.
  10. Decorate with white chocolate chips and oatmeal cream pie cookies.
  11. Chill the cake for 30 minutes, then slice and serve.

Notes

For a deeper flavor, consider adding spices like ginger or cardamom. This cake pairs beautifully with whipped cream or vanilla ice cream.
