Instructions

Prepare the oven and pan

Preheat your oven to 350°F (175°C). Grease and flour a 9-inch (23 cm) round cake pan.

Pro tip: Line the bottom with parchment paper for easy removal.

Mix dry ingredients

In a bowl, whisk together the flour, baking soda, and salt.

Cream butter and sugar

In a large bowl, beat the butter and sugar together until light and fluffy, about 3 minutes.

Pro tip: Use an electric mixer for best results.

Add eggs and bananas

Beat in the eggs one at a time, then mix in the mashed bananas, sour cream, and vanilla extract.

Pro tip: Ensure each egg is fully incorporated before adding the next.

Combine wet and dry ingredients

Gradually add the dry ingredients to the wet mixture, mixing just until combined.

Pro tip: Do not overmix to keep the cake tender.

Bake the cake

Pour the batter into the prepared pan and smooth the top. Bake for 30-35 minutes, or until a toothpick inserted into the centre comes out clean.

Pro tip: Rotate the pan halfway through baking for even cooking.

Cool the cake

Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.

Make the frosting

In a bowl, beat the butter until creamy. Gradually add the icing sugar, alternating with buttermilk, until smooth and spreadable. Mix in the vanilla extract.

Pro tip: Adjust the consistency with more icing sugar or buttermilk as needed.

Frost the cake

Spread the buttermilk frosting over the cooled cake.

Pro tip: Chill the frosting briefly if it becomes too soft to work with.
