Dry Ingredients

Wet Ingredients

  • 1 tsp vanilla extract
  • 1/2 cup sugar
  • 1/2 cup brown sugar
  • 1/2 cup sunflower oil, any flavorless oil - vegetable, canola
  • 4 ounces unsweetened applesauce
  • 1/2 cup buttermilk
  • 2 eggs


Salted Caramel Frosting

  • 1/2 cup unsalted butter, room temperature
  • 1 1/4 cups powdered sugar
  • 1/3 cup caramel sauce, I like Trader Joe's
  • 1/2 tsp vanilla extract
  • 1 tbsp whole milk
  • 1/4 tsp sea salt


  • drizzle caramel sauce
  • add chopped walnuts on top



  • Preheat oven to 350 degrees.
  • In a medium-size mixing bowl, combine the dry ingredients. Stir and set aside.
  • In a large mixing bowl, combine the wet ingredients.
  • Using an electric mixer, mix until well combined. Set aside.
  • Chop the walnuts.
  • Finely chop a Granny Smith Apple.

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.
