I stumbled upon this recipe years ago when faced with a bunch of overripe bananas. My family initially requested banana bread, but I wanted something more special for weekend company. This cake converted even my banana-skeptical friends into enthusiasts, and it's now requested for birthdays and potlucks regularly.
The Essential Ingredients
- All-purpose flour: Creates the sturdy yet tender structure needed for a perfect bundt cake
- Baking soda: Reacts with the acidity in bananas and sour cream to create the perfect rise
- Ground cinnamon: Complements the banana flavor with warm, aromatic notes
- Unsalted butter: Provides rich flavor and tender crumb when properly creamed with sugar
- Granulated and brown sugars: The combination creates depth of flavor and helps retain moisture
- Ripe bananas: Look for deeply speckled or black bananas for the sweetest, most intense flavor
- Sour cream: Adds tanginess while contributing to the incredibly moist texture
- Cream cheese: Forms the base of the luscious icing that sets this cake apart
- Confectioners' sugar: Dissolves perfectly into the icing for smooth, sweet results
- Vanilla extract: Enhances all the flavors while adding aromatic complexity

- → Why did my Banana Bundt Cake stick to the pan?
