A moist, tender cake that bridges banana bread and bread pudding with an unexpected twist of creamy peanut butter. The secret ingredient is instant vanilla pudding mix used as a dry powder, which creates incredible softness and adds rich vanilla notes throughout. Perfect for using overripe bananas, this cake delivers comfort food satisfaction for family desserts, potluck gatherings, or afternoon treats. The combination of sour cream and pudding mix creates an almost custardy texture that sets this apart from traditional banana bread.

Tips
Use the pudding mix as dry powder only - don't prepare it according to box directions as this adds moisture and vanilla flavor while keeping the cake incredibly soft
Don't overmix the batter once flour is added to prevent developing too much gluten which creates a tough, dense cake
Make sure bananas are very ripe with brown spots for maximum sweetness and easier mashing into the batter
Good to Know
Cover and store at room temperature for up to 3 days or refrigerate for up to 1 week
Can be made 1 day ahead - flavors actually improve overnight
Serve at room temperature or slightly warm, optionally with vanilla ice cream or whipped cream
Common Mistakes

FAQ
Can I use different pudding flavors?
Yes, banana cream or butterscotch pudding would complement the flavors well, though vanilla provides the most neutral enhancement.
What if I don't have ripe bananas?
Place unripe bananas in a 300°F oven for 15-20 minutes until skins blacken and bananas soften for baking use.
Can I freeze this cake?
Yes, wrap tightly and freeze for up to 3 months. Thaw at room temperature before serving for best texture.
