<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 175°C (350°F). Grease your 33x23cm (13x9-inch) baking pan thoroughly and line with parchment paper, leaving some overhang on the sides for easy removal. This extra step will ensure your beautiful cake won't stick to the pan.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>In a medium bowl, whisk together the flour, baking powder, baking soda, and salt until well combined. This proper mixing of dry ingredients ensures they'll be evenly distributed throughout your cake, giving you consistent leavening and flavor.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>In a large bowl, cream the softened butter and sugar using an electric mixer on medium-high speed for about 4-5 minutes until light and fluffy. This extended creaming process incorporates air into the batter, giving your cake a tender crumb. The mixture should lighten in color and increase in volume noticeably.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Add the eggs one at a time, beating well after each addition until fully incorporated. Be sure to scrape down the sides of the bowl between additions. Add the vanilla extract and mix to combine. The gradual addition of eggs prevents the mixture from curdling.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Reduce the mixer speed to low. Add the dry ingredients in three portions, alternating with the buttermilk (beginning and ending with the dry ingredients). Mix just until combined after each addition - overmixing at this stage will develop too much gluten, making your cake tough rather than tender.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Gently fold in the mashed bananas with a rubber spatula until evenly distributed throughout the batter. The riper your bananas, the more pronounced the banana flavor will be in your finished cake. The batter will look slightly curdled - this is perfectly normal!</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Pour the batter into your prepared baking pan, spreading it evenly to the corners. Tap the pan gently on the counter a few times to remove any large air bubbles. Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs (not wet batter). The top should be golden brown and spring back when lightly touched.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Allow the cake to cool completely in the pan set on a wire rack. This could take 1-2 hours. Patience is key here - frosting a warm cake will cause the frosting to melt and slide off.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>While the cake cools, prepare the vanilla frosting. Beat the softened butter in a large bowl using an electric mixer on medium-high speed until creamy and pale, about 3 minutes. Add the sifted powdered sugar gradually, about 125g at a time, beating well after each addition. Pour in the heavy cream, vanilla extract, and salt, then beat on medium-high speed for 3-4 minutes until very light and fluffy. The frosting should hold soft peaks and be spreadable but not runny.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>For the chocolate ganache, place the chopped chocolate in a heat-proof bowl. Heat the heavy cream in a small saucepan until it just begins to simmer (do not boil). Pour the hot cream over the chocolate and let it sit for 2-3 minutes, then whisk until smooth and glossy. Allow the ganache to cool slightly until it thickens but remains pourable.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>Once the cake has completely cooled, spread the vanilla frosting evenly over the top using an offset spatula. Create subtle swirls in the frosting to catch the ganache and fruit toppings. The frosting doesn't need to be perfectly smooth - those little valleys will hold your delicious toppings!</li><li class="MethodStepper"><h4 class="step-title">Step 12</h4>Drizzle the slightly cooled chocolate ganache over the frosted cake. You can do this in a zigzag pattern or any design you prefer. Work quickly before the ganache sets.</li><li class="MethodStepper"><h4 class="step-title">Step 13</h4>Arrange the diced strawberries, well-drained crushed pineapple, chopped nuts, and maraschino cherry halves evenly over the top of the cake, mimicking the classic banana split presentation. You can create sections of each topping or scatter them randomly for a more rustic look.</li><li class="MethodStepper"><h4 class="step-title">Step 14</h4>Refrigerate the cake for at least 30 minutes to allow the frosting to set before serving. This cake will keep well in the refrigerator for up to 4 days. For the best flavor and texture, let slices come to room temperature for about 15-20 minutes before serving. The contrasting temperatures and textures of warm cake, cool frosting, and varied toppings create the perfect banana split cake experience!</li></ol>
