Step 1

Preheat the oven to 350F and grease a 9×13 baking pan. Line with parchment paper and set aside.

Step 2

Whisk together the flour, salt, baking soda, baking powder, and spices in a medium bowl and set aside.

Step 3

In a large mixing bowl, whisk together the oil, sugars, vanilla, eggs, and apple butter. Mix in the grated apples.

Step 4

Whisk in half of the dry ingredients. Just before combined, whisk in the milk. Then whisk in the rest of the dry ingredients.

Step 5

Pour the batter into the baking pan and spread even. Bake for 35-40 minutes, or until a toothpick in the center comes out clean with a few moist crumbs.

Step 6

Allow the cake to cool completely before frosting.

Step 7

Add the chilled cream cheese and sugar to the bowl of a stand mixer with the whisk attachment.

Step 8

Whip the cream cheese on high speed until smooth.

Step 9

With the mixer on medium-high speed, slowly pour in the heavy cream. Continue to whip on high speed for about 3 minutes, or until the frosting is light and fluffy.

Step 10

Spread the frosting on the cooled cake and top with a few spoonfuls of apple butter. Gently swirl into the frosting and top with a sprinkle of walnuts. Enjoy!
