Ingredients for australian women's weekly banana cake

Ripe bananas, warm spices, and buttery layers—everything you need for that legendary Australian Women's Weekly banana cake.

The bananas are the heart of this cake. Look for ones with brown spots—they're sweeter and pack more moisture. Coles or Woolworths usually have perfect ones, or grab the ones with the darkest spots at the store. I always mash them by hand for that extra tender texture. The flour? King Arthur or IKEA's own brand work perfectly—just sift it for a lighter crumb. And don't skip the nutmeg—it's what gives that classic spice profile. If you only have ground nutmeg, toast it lightly in a dry pan first for deeper flavor.

No overripe bananas? Use 1 cup mashed sweet potato plus 1/2 cup applesauce—it mimics the moisture perfectly. Running short on butter? Coconut oil works in a pinch, though it gives a slightly different texture. For the frosting, if you can't find confectioners' sugar, blend regular sugar in a food processor for 30 seconds. The vanilla extract matters here—Nielsen-Massey is my go-to, but any pure extract will do. Want extra richness? Add 1 tbsp of melted white chocolate chips to the frosting. For texture lovers, fold in 1/2 cup chopped walnuts to the batter.

This cake keeps beautifully—5 days at room temperature wrapped tightly, or 1 week in the fridge. The frosting softens in warm rooms, so store it covered in the fridge and let it sit at room temp for 10 minutes before serving. For make-ahead bakers, assemble the cake (without frosting) 2 days ahead—it actually tastes better after the flavors meld. Freeze the unfrosted layers for up to 3 months. Just thaw overnight in the fridge before adding frosting.

Step-by-step instructions for Australian Women's weekly banana cake

Here's how to bake the legendary moist banana cake with perfect spice layers and velvety frosting.

Start by mashing the 3 whole ripe bananas in a large mixing bowl until completely smooth. I like to use a fork first to break them up, then press through a fine-mesh sieve to remove any skins or fibrous bits. This ensures a silky texture in your cake.

Add the 1 cup unsalted butter and 1.5 cups granulated sugar to the mashed bananas. Mix until completely combined and the butter is fully incorporated. The mixture should be smooth and pale yellow. Here's the thing—don't rush this step. The butter needs to be fully melted and evenly distributed for that classic moist texture we're after.

In a separate bowl, whisk together the 2 whole large eggs, 1 cup milk, 1 tablespoon vanilla extract, 2 teaspoons ground cinnamon, 0.5 teaspoon ground nutmeg, 1 teaspoon baking soda, and 0.5 teaspoon salt. The baking soda and salt should dissolve completely in the milk before adding to the banana mixture.

Now gently fold the wet ingredients into the banana mixture using a spatula. Be careful not to overmix—just combine until everything is evenly distributed. You'll notice the batter will be thick but still pourable. This is perfect for creating that tender crumb we want. If you're worried about overmixing, it's better to err on the side of under—just make sure all the flour is incorporated.

Preheat your oven to 350°F. Grease and line two 9-inch round cake pans with parchment paper. Divide the batter evenly between the two pans, filling each about two-thirds full. The batter should be level with the top of the pans.

Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. I know it seems counterintuitive, but don't overbake—this cake continues cooking slightly as it cools. The edges should be golden brown, but the center should still look slightly underdone when you remove it from the oven. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.

While the cakes cool, prepare the frosting by beating the 1 cup butter (for frosting) until smooth and creamy. Gradually add the 3 cups confectioners' sugar, 2 tablespoons milk (for frosting), and 0.5 tablespoon vanilla extract (for frosting), beating on medium speed until light and fluffy. This should take about 2-3 minutes with an electric mixer.

Here's where it gets fun—the frosting should be thick enough to hold its shape but still spreadable. If it's too thick, add a splash more milk, 1 teaspoon at a time. If it's too thin, add a bit more confectioners' sugar. The frosting should be smooth and glossy when you're done. Taste it—it should be sweet but not overpowering, with just a hint of vanilla.

Once the cakes are completely cool, place one layer on a serving plate. Spread about half of the frosting evenly over the top, then place the second layer on top. Spread the remaining frosting over the top and sides of the cake, creating a smooth finish. I like to use a bench scraper to get those clean edges.

For extra decoration, you can sprinkle a pinch of ground cinnamon or a few extra banana slices on top. Let the cake sit at room temperature for at least 30 minutes before slicing to allow the frosting to set. This classic Australian banana cake serves 12, and each slice delivers that perfect balance of moist banana flavor, warm spices, and buttery frosting that makes it legendary.

Dietary considerations for this recipe

Gluten-Free Adaptation

For a gluten-free version, replace the 2.5 cups all-purpose flour with a high-quality gluten-free blend like King Arthur Measure for Measure or Bob's Red Mill 1:1 Baking Flour. Add 1 teaspoon xanthan gum to the dry ingredients to improve texture and binding.

I've found this blend works best—it mimics the tender crumb of traditional flour while keeping the cake moist. 🌾

Dairy-Free Options

Swap the 1 cup butter and 1 cup milk for dairy-free alternatives. Use Earth Balance vegan butter (room temperature) and unsweetened almond milk or oat milk for the liquid.

For the frosting, replace the butter with Miyoko's Creamery vegan butter and add 1 tablespoon coconut cream to achieve the right consistency. The flavor remains rich and buttery!

Lower Sugar Version

Reduce the granulated sugar to 1 cup and replace the remaining 0.5 cup with unsweetened applesauce. For the frosting, use 2 cups confectioners' sugar and add 1 tablespoon lemon juice for brightness.

This keeps the cake moist while cutting back on refined sugar. I've tested this with ripe bananas, and it still delivers that signature caramelized flavor.

Nut-Free Considerations

If you're avoiding nuts, skip the walnuts in the batter entirely. The cake remains delicious with just the banana, spice, and buttery layers. For extra texture, fold in ½ cup dried cranberries or chocolate chips instead. The frosting stays nut-free as well, so you won't miss the crunch. 🍫

Vegan Adaptation

For a fully vegan version, use flax eggs (2 tbsp ground flaxseed + 6 tbsp water) and replace the butter with coconut oil. The frosting can be made with vegan butter and coconut cream instead of milk.

I've found that adding 1 teaspoon vanilla bean paste enhances the flavor, as plant-based extracts can be less potent. The texture remains tender, though slightly denser than the traditional version.
