Banana, walnut, and chocolate are always an amazing combination of ingredients, no matter what the delivery system, but it really doesn't get any better than in this ganache-frosted cupcake. A close second would be a chocolate-dipped frozen banana, rolled in walnuts, which is also a great treat, although much more awkward to eat in public. Feel free to omit the frosting and just enjoy these as muffins.

Ingredient Checklist
For the Dark Chocolate Frosting:


Instructions Checklist
  • Preheat oven to 350 degrees F (175 degrees C) and line a 12-cup muffin tin with liners.

  • Whisk flour, baking powder, baking soda, and salt together in a bowl.

  • Mash bananas with milk and vanilla extract until smooth.

  • Mix butter and sugar together with a spatula until creamy. Whisk in eggs, 1 at a time, then whisk in the banana mixture. Add walnuts, chocolate, and the flour mixture. Mix batter with a spatula until no dry spots remain.

  • Fill muffin cups to the top with batter, then distribute excess batter as needed. Tap pan against the counter to expel any air bubbles.

  • Bake in the preheated oven until tops are lightly browned, about 25 minutes. Let cupcakes cool to room temperature, at least 20 minutes.

  • Pour hot cream over chocolate chips in a bowl. Let sit for a few minutes, then whisk, increasing speed gradually, until color is uniform. Spread ganache over the cooled cupcakes and garnish with banana chips. Refrigerate to firm up the frosting, if desired.

I made no changes to the ingredients, although I didn't make the ganache because I thought it was plenty sweet and rich already. It tastes like a banana bread, but better. The inside was moist and the outside becomes slightly crispy and browned. Next time, I might add banana extract for stronger banana flavor, more like the famous Ben & Jerry's ice cream.

Should have been 15+ cupcakes filled almost to the top. I squeezed it into 12 and they just made a big mess. The recipe didnt specify that you should use unsalted butter, so mine were a little salty. I would have ommitted the salt had I known.... I used half brown sugar. Read More

I have an issue with over baking any kind of banana bread/cupcake in my oven… Next time I will put these in for 20 minutes because my oven plays games with me. But the overall flavor was great. I would also probably cut the 1 cup of chocolate in the batter down to half a cup… Not sure if my bananas just weren’t ripe enough, but the chocolate between the chips and the ganache overpowered any banana flavor. But they were still delicious! Read More
