  • Vanilla extract
  • All-purpose flour

Can Bananas Be Too Ripe for Banana Bread?

No, unless the banana is completely liquefied or moldy, it’s not too ripe for banana bread! The darker the better; your bananas should at least have lots of black and brown spots, but bananas that are more brown than yellow are best of all. 

Not only do darker bananas lend more sweetness to this Chocolate Banana Bread recipe, they also have a more pronounced banana flavor. A banana that’s still yellow with streaks of green has a bland flavor that yields a lackluster banana bread.

How to Make Chocolate Banana Bread

Here’s what you’ll need to do to make this moist, decadent banana bread recipe.

Prepare. Preheat your oven to 350ºF and grease or line a 9 x 5-inch loaf pan with parchment paper.

Mash the bananas. Place the bananas in a large mixing bowl and mash them with a fork or potato masher. A few chunks are okay, but the bananas should be mostly smooth; if you prefer, you can pulse the bananas in a blender instead of mashing them by hand.

Mix the wet ingredients. Add the sugar, melted butter, eggs, and vanilla extract to the bowl with the mashed bananas. Use a hand mixer on low speed to mix until combined. 

Mix the dry ingredients. In a separate mixing bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. Slowly mix the dry ingredients into the wet ingredients, then fold in the chocolate chips.

Bake. Pour the batter into the prepared loaf pan and scatter additional chocolate chips over the top of the batter, if desired. Bake for 60 minutes, then check the bread and add additional time in 5 or 10 minute increments, or until a toothpick inserted into the center comes out mostly clean.

Cool and serve. Let the loaf cool for 15 minutes in the loaf pan, then it transfer to a wire rack to finish cooling.

Tips for Success

This Chocolate Banana Bread recipe is fairly straightforward, but these additional hints and tips will help make sure it turns out perfect.

  • Measure the mashed banana. After you’ve mashed the banana, measure it. Bananas vary in size, and adding too much or too little can affect the texture of your banana bread.
  • Tent the bread if needed. Sometimes banana bread can trick you; it can look done on the outside but still be doughy in the middle. That’s when tenting the bread with aluminum foil comes in handy. It protects the top from becoming too brown, overcooked, or crusty.
  • Know your loaf pan. The baking time for this recipe is a large range because every oven if different and various loaf pans bake at different rates. There are two popular loaf pan sizes, 9×5 and 8.5×4.5, and although the numbers are similar, the pans actually differ in size by 15%. The 8.5×4.5 pan will yield a taller, more domed bread and will take 5-10 minutes longer when baking.

What Makes Banana Bread Moist?

Bananas make banana bread naturally moist, but if your loaf turns out dry, there are two likely culprits. 

First, it’s possible that you didn’t add enough mashed banana; this is why it’s so important to measure it. Second, you may have added too much flour to the recipe. Use the spoon-and-sweep method to make sure your flour measurements are accurate.

  • ½ teaspoon salt
