Instructions

1. 1 Preheat oven to 350 degrees F (175 degrees C). Grease two 8-inch square pans and line the bottoms with parchment paper.
2. 2 Whisk flour, baking powder, cinnamon, ginger, baking soda, salt, nutmeg, cloves, and allspice together in a bowl; set aside.
3. 3 Beat butter, oil, brown sugar, and white sugar together in a large bowl with an electric mixer until light and fluffy. Add eggs one at a time, beating well after each addition. Beat batter for an additional 2 minutes after adding last egg. Beat in vanilla extract. Pour in half of the flour mixture; mix on low speed until just combined. Pour in buttermilk; mix until just combined. Pour in remaining flour mixture; mix until just combined. Fold in carrot, apple, raisins, and pecans.
4. 4 Divide batter evenly between the two pans. Spread into an even layer in each pan.
5. 5 Bake in the preheated oven until the top of the cake springs back lightly when touched and a toothpick inserted near the center comes out clean, 40 to 45 minutes.
6. 6 Allow cakes to cool in pans for 20 minutes; remove to a wire rack to cool completely, about 1 1/2 hours more.
7. 7 Beat butter in a large bowl with an electric mixer until completely smooth; beat in cream cheese until smooth and thoroughly combined. Beat in confectioners' sugar 1 cup at a time, mixing well after each addition; beat in vanilla and salt. Add in heavy cream; beat on medium-high until frosting is slightly fluffy, about 2 minutes.
8. 8 Spread frosting onto one cooled cake layer. Stack layers; frost top and sides.
