Why You'll Love This Recipe
Tall, bakery-style domes. A hot-then-lower oven start gives these muffins a beautiful high rise.
Melty chocolate chunks. Chopped chocolate bar makes pools and shards a bag of chips just can't match.
A great use for overripe bananas. The riper the better — they bring moisture and natural sweetness, just like in my sourdough banana bread.
Warm, cozy spice. Cinnamon, nutmeg, and a touch of cardamom deepen the banana flavor.
Quick and easy. One bowl of wet, one of dry, and they're in the oven in about 10 minutes.

Ingredients
- Ripe bananas — the riper (and browner) the better; the main sweetener and moisture.
- Egg and vanilla — for structure and flavor.
- Brown sugar — light or dark, for moisture and caramel depth.
- Melted butter — for a tender, rich crumb.
- Milk — added as needed to reach the right batter consistency.
- All-purpose flour, baking powder, baking soda, and salt — the base and lift.
- Cinnamon, nutmeg, and cardamom — warm spices that round out the banana.
- Chopped chocolate bar — for melty chunks throughout.

How to Make Chocolate Chunk Banana Muffins
Step 1: Preheat your oven to 425F. In a small bowl mix wet ingredients until combined. In a separate bowl mix dry ingredients.
Combine wet and dry ingredients and mix until just combined (do not over mix)
Step 2: Roughly chop chocolate and stir in to the batter.
Step 3: Add milk (if needed) 1 tablespoon at a time until you reach this consistency. You might need more or less milk depending on how ripe your bananas are.
Step 4: Divide the batter between 12 muffin liners. I used two muffin pans in order to let the muffins spread without hitting each other. I use a three tablesppon cookie scoop to portion out my muffins.
Bake for 5 mins at 425 and then switch to 350 for another 15-16 mins or until you can stick a toothpick in it and it comes out with just a few crumbs. Don’t open the oven when you change the temp!
Weigh your ingredients! Using a kitchen scale ensures your measurements are accurate, which is key for getting consistent results in baking. It takes the guesswork out of measuring and helps your recipes turn out exactly as intended every time.
Expert Tips
1. Use very ripe bananas. Lots of brown spots means more sweetness and stronger banana flavor.
2. Don't overmix. Mix just until the flour disappears — overmixing makes dense, flat muffins.
3. Keep the batter thick. Add milk only as needed; how much depends on how ripe and wet your bananas are.
4. Start hot, then lower. The 425°F blast sets a tall dome before the 350°F finish bakes them through — don't open the oven when you switch temps.
5. Give them room. Spacing the muffins (two pans, or every other cup) lets them spread and dome without touching.
What Makes This Recipe Special?
Banana muffins are a classic, but a few small choices push these into bakery territory. First, the high-heat start: blasting the muffins at 425°F before dropping to 350°F creates that tall, domed top you get from a real bakery. Second, chopped chocolate bar instead of chips — it melts into dramatic pools and thin shards for chocolate in every bite. And third, a trio of warm spices (cinnamon, nutmeg, and cardamom) that deepens the banana flavor beyond the usual.
The result is a moist, tender, chocolate-loaded muffin that feels special enough for dessert but easy enough for a weekday breakfast. It's the same use-your-ripe-bananas magic as my chocolate chunk banana bread, in a grab-and-go form.
Chocolate Chunk Banana Muffin FAQs
