What is the baking time for the Sour Cream Banana Cake?

Bake the Sour Cream Banana Cake in a preheated oven at 350°F (175°C) for 30-35 minutes. Check for doneness by inserting a toothpick into the center; it should come out clean.

Can I substitute the sour cream in this cake?

Yes, you can substitute sour cream with plain yogurt or buttermilk. These alternatives will maintain moisture and acidity, similar to sour cream, but may slightly alter the flavor.

What size pan is recommended for this cake?

Use a 9-inch round cake pan for the Sour Cream Banana Cake. You can also use an 8-inch pan, but be mindful that the baking time may need to be adjusted.

How should I store leftover Sour Cream Banana Cake?

Store leftover cake in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. You can also freeze slices wrapped tightly in plastic wrap for up to 2 months.

What can I use instead of white chocolate in this recipe?

You can substitute white chocolate with semi-sweet or dark chocolate if preferred. Keep in mind that this will alter the sweetness and flavor profile of the cake.

Tips:

- Ensure all ingredients are at room temperature before starting to mix, as this helps create a smoother batter.

- Use ripe bananas with brown spots for maximum sweetness and flavor.

- If you don't have self-raising flour, you can substitute with all-purpose flour and add an extra 1/2 teaspoon of baking powder.

- Gently fold the white chocolate into the batter to ensure even distribution without overmixing.

- For an extra touch, consider adding a cream cheese frosting or a simple glaze on top of the cake.

- Let the cake cool completely before slicing to avoid it falling apart.
