Prepare the Apple Walnut Cake

  • Add the dry ingredients to the wet in 2 batches.
  • Mix well until well combined, however DO NOT OVERMIX.
  • Add the chopped walnuts and apple to the batter. Fold ingredients into the batter.
  • Pour batter into a well-greased 9" round cake pan. You can also use a square cake pan.
  • Bake cake for 40 minutes at 350 degrees. Make sure you check the cake after 30 minutes every 5 minutes as oven temperatures vary. The cake is done. Let it cool for 45 minutes before flipping.

Make the Salted Caramel Frosting

  • In a large mixing bowl, combine all the ingredients except milk and salt. So combine butter, powdered sugar, vanilla, and store-bought caramel sauce. Blend with an electric mixer.
  • Add milk and salt. Mix well.
  • Now you should have perfectly smooth and creamy salted caramel frosting.
  • Once the cake cools, carefully flip it onto a cake stand. Frost with Salted Caramel Frosting once completely cooled. Drizzle caramel sauce on top and garnish with chopped walnuts.
