Method
Technical Preparation
- Preheat the oven to 350°F.
- Coat two 9x9-inch cake pans with vegetable oil spray.
- Line the bottom of each pan with parchment paper and coat the paper again to ensure a clean release.
- In a small ceramic bowl, whisk together the pastry flour, all-purpose flour, cinnamon, baking soda, and salt until uniform.
Developing the Batter
- In the bowl of an electric mixer, cream 1 cup of butter with both sugars until light and fluffy.
- Incorporate the eggs one at a time, ensuring each is fully emulsified before adding the next.
- Alternating in batches, pour in one-third of the flour mixture followed by a portion of the apple butter.
- Mix on low speed until just combined, continuing until all ingredients are integrated.
The Thermal Execution
- Distribute the batter evenly between the two prepared pans.
- Bake for 30 minutes, or until a tester inserted into the center comes out clean.
- Cool the cakes in the pans for 10 minutes.
- Invert the cakes onto a wire rack, remove the parchment paper, and allow them to cool completely.
The Frosting & Assembly
- In a clean mixer bowl, combine confectioners’ sugar, cream cheese, ½ cup butter, and vanilla.
- Whisk until smooth and creamy, adding a teaspoon of milk if necessary to reach a spreadable consistency.
- Place the first cake layer on a serving pedestal and slather with a generous layer of frosting.
- Top with the second cake and frost the top and sides.
- Finish by scattering the chopped walnuts across the top of the cake.
