1/4 teaspoon salt
1/2 cup unsalted butter, softened
1/2 cup granulated sugar

2 cups powdered sugar

Directions
-
Preheat the oven to 350°F (177°C) and line a 12-cup muffin tin with cupcake liners.
-
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.

In a large bowl, beat the butter, granulated sugar, and brown sugar together until light and creamy. Add the eggs one at a time, mixing well after each addition.
-
Mix in the sour cream, vanilla extract, and mashed bananas until fully combined.
-
Gradually add the dry ingredients to the wet ingredients, mixing just until combined. Avoid overmixing to keep the cupcakes tender.

Divide the batter evenly among the cupcake liners, filling each about two-thirds full.
-
Bake for 18–20 minutes, or until a toothpick inserted into the center comes out clean. Allow the cupcakes to cool completely before frosting.
-
To prepare the frosting, beat the butter and peanut butter together until smooth and creamy. Add the cocoa powder and mix until incorporated.
-
Gradually add the powdered sugar, heavy cream, vanilla extract, and salt. Beat on high speed until light, fluffy, and smooth. Add more cream if needed to reach your desired consistency.

FAQs
Can I use frozen bananas?
Yes, thaw the bananas completely and drain any excess liquid before mashing and adding to the batter.
How ripe should the bananas be?
Very ripe bananas with brown spots are ideal, as they provide maximum sweetness and moisture.
Can I make this recipe into a cake instead?
Yes, you can bake the batter in an 8-inch round cake pan. Adjust the baking time to 25–30 minutes and check for doneness with a toothpick.
Can I make the frosting ahead of time?
Yes, the frosting can be made up to 2 days in advance and stored in the refrigerator. Let it soften slightly and re-whip before using.
What if I don’t have sour cream?
You can substitute plain Greek yogurt or buttermilk in equal amounts.
Can I reduce the sugar?
You may slightly reduce the granulated sugar, but keep in mind this may affect the texture and moisture.
How do I get perfectly smooth frosting?
Beat the frosting on high speed for several minutes and sift the powdered sugar before adding it.
Can I make these cupcakes dairy-free?
Yes, substitute plant-based butter, dairy-free yogurt, and non-dairy cream alternatives.
Why are my cupcakes dense?
Overmixing the batter can cause dense cupcakes. Mix just until the ingredients are combined.
Can I pipe the frosting?
Absolutely. The frosting is sturdy enough for piping decorative swirls using a piping bag and your favorite tip.
