Retro Hummingbird Cake

Prepare the Cakes - Adjust oven rack to middle position and preheat oven to 350°F (175ºC). Lightly grease three 8-inch round cake pans with baking spray and line with parchment. Set aside.

Prepare the Cakes - Spread pecan halves in an even layer on a rimmed baking sheet. Bake until fragrant and toasted, about 8 minutes. Set aside until cool enough to handle, then chop finely (pieces no larger than ¼-inch). Set aside.

Prepare the Cakes - In a large bowl, whisk together sugar, oil, eggs, and vanilla until smooth. Drain 1 tablespoon of juice from crushed pineapple; set aside for Frosting.

Prepare the Cakes - Chop 2 of the bananas into small pieces (about 1 cup), and mash the other two (about 2/3 cup). Add chopped and mashed bananas to sugar mixture along with remaining crushed pineapple and its juice. Using a flexible spatula, stir to combine. In another large bowl, whisk together flour, cinnamon, salt, baking soda, baking powder, and allspice until evenly combined.

Prepare the Cakes - Pour sugar mixture into flour mixture and, using the same spatula, gently fold until only a few streaks of flour remain. Fold in reserved toasted chopped pecans until evenly dispersed. Divide batter evenly between prepared cake pans (about 650g or 23 ounces per pan). Gently tap pans on counter to smooth batter and release any air bubbles.

Prepare the Cakes - Bake until cakes are golden on top, spring back gently to the touch, and an instant read thermometer inserted in the center registers 200°F (93ºC), 25 to 28 minutes.

Prepare the Cakes - Cool cakes in their pan on a cooling rack for 10 minutes. Run an offset spatula or butter knife around edges of cakes, then invert cake onto a plate and transfer back to rack to cool completely, parchment-side down, 1 1/2 to 2 hours.

Prepare the Frosting - In the bowl of a stand mixer fitted with a paddle attachment, or, using an electric hand mixer, beat cream cheese and butter on medium-low speed until smooth and creamy, 1 to 2 minutes, stopping to scrape down sides as needed. Reduce mixer speed to low, and gradually add powdered sugar, beating until fully incorporated after each addition. Add reserved 1 tablespoon pineapple juice and vanilla, and increase mixer speed to medium-high; beat until fluffy, 1 to 2 minutes.

Assembly - Using a serrated knife, level cakes if necessary and set the scraps aside for snacking. Remove and discard parchment paper. Place 1 layer, top-side-up, on a turntable. If you like, a waxed cardboard cake round can first be placed underneath, secured to the turntable with a scrap of damp paper towel. Top with 1 cup frosting, using an offset spatula to spread it evenly from edge to edge. Repeat with the second and third layers, placing the cake layers bottom-side up, then cover the top and sides of the cake with a very thin layer of frosting to form a crumb coat. Refrigerate, uncovered, until frosting is mostly set, 30 to 40 minutes.

Assembly - Remove cake from refrigerator. Using an offset spatula, cover cake with remaining frosting, spreading it as smoothly as you can over top and sides of cake. Decorate with pecans, as desired.
