This tender four-layer chiffon cake is layered with fresh bananas and finished with whipped cream frosting; perfect for birthdays, celebrations, or whenever you’re craving a slice of nostalgia.
Prep Oven & Pans: Preheat oven to 325℉ (160℃). Line bottom of two 8-inch cake pans with parchment paper.
Make Meringue: Beat egg whites with cream of tartar until soft peaks form. Gradually add sugar, beating until stiff, glossy peaks form.
Mix Cake Batter: Sift cake flour, sugar, baking powder, baking soda, andsalt. Beat in oil, mashed bananas, and vanilla. Add buttermilk and egg yolks, beat until smooth. Add in meringue in two stages, folding gently until just combined.
Bake Layers: Divide batter between pans. Bake 40–50 min, or until a toothpick comes out clean. Cool in pans for 10 minutes. Run a thin knife blade around the edge of the cake pans, and then turn the cakes out onto wire racks to cool completely, top side up.
Make Cake Crumbs: Use a long serrated knife to level the tops of the cooled layers. Dry trimmed pieces in a 170℉ oven for about 30 minutes, flipping once. Pulse into crumbs in a food processor; set aside.
Make Whipped Cream: Chill mixing bowl. Beat heavy cream with vanilla. Gradually add powdered sugar + xanthan gum mixture, whipping to soft peaks.
Assemble Cake: Split each cake layer in half horizontally, for 4 total layers. Spread whipped cream and cover with banana slices between layers.
Frost & Decorate: Cover sides with whipped cream, press crumbs onto sides. Frost top, pipe borders, and add optional center rosette + maraschino cherry.
Chill & Serve: Refrigerate until ready to serve. Slice with a warm, clean knife for best results.
Notes
Xanthan gum: In the cake xanthan gum acts as a binder and thickener, improving crumb structure and enhancing moisture retention. In the whipped cream filling and frosting, it acts as a structural stabilizer for the delicate whipped cream. You can buy xanthan gum in the baking aisle of your local grocery store. It's also found in many bulk food sections. Quick Tips

Fold meringue gently; don’t overmix.
Line pans with parchment; don’t grease sides.
Chill layers before filling; use cold cream for frosting.
Keep cake refrigerated until serving, especially outdoors.
