🍌🍫 Chocolate Banana Cake with Chocolate Ganache

🧁 Ingredients

For the Chocolate Banana Cake:

  • 1¾ cups (220g) all-purpose flour
  • ¾ cup (65g) unsweetened cocoa powder
  • 1½ tsp baking powder
  • 1 tsp baking soda
  • ½ tsp salt
  • 3 large ripe bananas (about 1½ cups mashed)
  • ¾ cup (150g) brown sugar
  • ½ cup (100g) granulated sugar
  • ½ cup (120ml) vegetable oil or melted butter
  • 2 large eggs
  • 1 tsp vanilla extract
  • ¾ cup (180ml) buttermilk or plain yogurt

Optional:

  • ½ cup chocolate chips or chopped dark chocolate (folded into the batter)

For the Chocolate Ganache:

  • 1 cup (170g) dark or semi-sweet chocolate chips
  • ½ cup (120ml) heavy cream
  • 1 tbsp butter (optional, for extra shine)

👩‍🍳 Instructions

1. Prep & Preheat

Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round or square cake pan — or line with parchment for easy removal.

2. Mix the Dry Ingredients

In a bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt. Set aside.

3. Mash the Bananas

In a large mixing bowl, mash the bananas with a fork until mostly smooth. Add brown sugar, white sugar, oil, eggs, vanilla, and buttermilk. Mix until combined.

4. Combine Wet & Dry

Add the dry ingredients to the banana mixture. Mix until just combined — don’t overmix! If using chocolate chips, fold them in now.

5. Bake

Pour the batter into the prepared pan and smooth the top. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.

Let the cake cool completely before adding ganache.
