Method
- Preheat oven to 350 degrees F. Line a 9×13 pan with parchment paper that extends beyond the pan and spray with nonstick cooking spray. Set aside.
- Mix cinnamon, ginger, cloves, allspice, and nutmeg together in a large bowl. Remove 1/2 teaspoon for the frosting. To the large bowl, mix in flour, baking powder, baking soda and salt. Set aside.
- With a stand or hand mixer, beat butter and sugar over medium high speed until light and fluffy, about 4 minutes, scraping down sides as needed. With mixer running on medium speed, beat in maple syrup, molasses and vanilla until well combined followed by eggs, then egg yolks, one at a time, beating just until the yellow disappears after each egg.
- Gradually add flour mixture to butter/sugar mixture in thirds, alternately with sour cream in between each third, beating until just combined after each addition. Stir in apples and walnuts. Spoon batter into prepared pan.
- Bake at 350 degrees F until a wood pick inserted near the center of cake comes out clean, 34 – 40 minutes. Let cake cool in pan on wire rack, about 2 hours before frosting OR serve warm directly right out of the oven without frosting.
- Using a stand or hand mixer, beat the cream cheese, butter, sour cream, maple syrup, vanilla, salt and reserved 1/2 teaspoon spices at medium high speed until well combined. Add confectioners’ sugar ½ cup at a time then beat until very fluffy, about 2 minutes. Add either more maple syrup if frosting is too thick or more sugar if too thin to reach desired consistency.
- Evenly spread frosting over cake and sprinkle with chopped walnuts (optional).
- Refrigerate cake for up to 5 days and bring to room temperature before serving.
Notes
Refrigerate any leftovers for up to 5 days. Bring to room temperature before serving.
