"For the chocolate chip butter cake layers: Position a rack in the middle of the oven and preheat to 350 degrees Fahrenheit. Generously coat three 8-inch-by-2-inch or 9-inch-by-2-inch round cake pans with butter (you can also use two 9-inch pans to make thicker cakes, which you can split into four layers total). Line the bottoms of the cake pans with a circle of parchment paper. Lightly butter the parchment and dust with flour; tap the side of the pans on the countertop to dislodge any excess flour. Onto a sheet of parchment, sift together the measured flour and baking powder. In the bowl of a stand mixer fitted with the paddle attachment, beat the measured butter, sugar, and salt on medium-high speed until lightened and fluffy. Add the eggs and yolks 1 at a time, beating well after each addition. Scrape down the sides of the bowl a few times while beating. On low speed, add half of the sifted dry ingredients and beat until combined. Beat in the sour cream and vanilla. Add the remaining dry ingredients and the chocolate chips, beating until combined. Divide the batter among the prepared pans (you can make sure they are divided evenly by using a scale to weigh them). Bake until a toothpick inserted into the center of the cakes comes out clean, about 20 minutes. Let cool in the pans on wire racks for about 10 minutes. Invert the cakes onto the racks, peel off the parchment, and let cool before frosting. For the whipped cream filling: Using a whisk or an electric mixer with the whip attachment, beat the cream, sugar, and vanilla to medium peaks (when you lift the beater, it should look like a Dairy Queen soft-serve curl). Be careful not to overwhip or it will become grainy and, eventually, turn to butter. To assemble: Place a cooled cake layer on a stand or presentation platter. Spread with a third of the dulce de leche or caramel sauce. Cover evenly with a layer of banana slices. Carefully spread with a third of the whipped cream filling. Place the second cake layer on top; repeat the layers of dulce de leche, bananas, and whipped cream filling. Repeat with the third cake layer, decorating the very top with just a few banana slices or a sprinkle of chocolate chips (or both)."^^<http://www.w3.org/2001/XMLSchema#string>
