It’s one of those one bowl recipes the whole family can help with, and honestly, it’s hard to wait for them to cool before sneaking one. I love to make these for an after school snack, and they’re freezer-friendly too which means they are a great grab-and-go breakfast too!

It’s so hard to help the readers understand just how much we loved a certain recipe, and even more difficult to try through words and photos to convince you to make it for yourselves. So, here goes my attempt, or 5 reasons that you need to make these gosh darn totally delicious, melt in your mouth, awesome (are you catching my drift here?) double chocolate banana muffins.

5 Reasons You Need to Make These Chocolate Banana Muffins

Carrian Cheney

1. Tender: These babies are tender. Mercy, they are tender! Imagine a chocolate version of the best, most moist banana bread ever. Bam! That’s this muffin.

2. Size: We love these muffins jumbo size and we never share! Psst…you can make them standard size too if you prefer.

3. Double Chocolate: There’s melty chocolate chips inside! It’s like a little gold mine of chocolate and trust me, you’ll feel like a millionaire by the time you’re finished.

4. Balance: The chocolate flavor is not overpowering, not overly rich, but still full chocolate. These are definitely well balanced and the chocolate flavor really is so wonderful.

5. Flavor: The rich chocolate flavor!! Be sure to use ripe bananas so you get that natural sweetness and bold banana flavor.

Ingredients for Banana Chocolate Muffins

  • Cocoa Powder: Adds rich chocolate flavor and color to the muffins.
  • Flour: Just good ol’ all purpose flour is all you need. 
  • Baking Soda, Baking Powder, Cream of Tartar, Salt: Added for rise, texture and flavor.
  • Shortening: You can use butter instead, but I’ve found shortening results in a more moist muffin.
  • Eggs: Give structure to the muffins.
  • Vanilla Extract: Adds flavor.
  • Sugar: Adds sweetness.
  • Bananas: Make sure they are ripe to give the best sweetness and flavor to the muffins.
  • Semi Sweet Chocolate Chips: What makes these muffins double chocolate! They can be omitted if you want, but I don’t know why anyone would do that!

How to Make Double Chocolate Banana Muffins

  1. Prep: Preheat the oven to 375 degrees F. Line a jumbo muffin tin with jumbo paper liners (or use regular muffin tin).
  2. Dry Ingredients: Whisk all the dry ingredients together in a medium size mixing bowl.
  3. Wet Ingredients: In a large bowl, stir all the wet ingredients together until smooth.
  4. Combine: Add a little of the flour mixture and mix, then a little of the mashed banana and mix and keep repeating until everything is combined.
  5. Fold: Fold in the chocolate chips and then fill each muffin cup about 2/3 full.
  6. Bake: Place the muffin pan in the oven and bake for 25-30 minutes. Allow to cool before eating.

Can You Bake Muffin Batter In a Loaf Pan?

Muffins can be turned into quick bread by following a few simple steps.

Set the oven rack in the middle position.

Decrease the oven temperature by 50 degrees, and bake until a toothpick inserted in the center of the loaf comes out either “with few moist crumbs attached” or “clean”.

This will take about 60 to 70 minutes.

We actually have a double chocolate banana bread, so head there for the complete recipe!

How to Know When a Banana is Ripe

Bananas are picked green, then as the fruit ripens, the peel changes from green to yellow, and then to yellow with a few brown speckles. My preferred ripeness for this recipe is bright yellow bananas with brown spots all over them.

Bananas gradually turn dark brown and become softer and sweeter and will eventually go bad. If the peels are dark brown, the inside of the bananas are fresh and flavorful for several days.

If the bananas are too ripe for your liking, use them in smoothies or banana bread.

Why Did My Muffins Sink in the Middle?

I’ve been there many times…the muffins are rising in the oven beautifully with that bakery style dome on top, I pull them out and they collapse. It’s so frustrating! The most common culprit for sunken muffins is underbaking. Before removing muffins from the oven, test them by poking a toothpick in the middle. It should come out clean or with a few moist crumbs. 

The other common causes are temperature problems or bad leavening agents. If an oven is too hot, the muffins will rise too fast and then collapse because the structure hasn’t had time to develop. Opening the oven too often can often cause temperature fluctuations that will affect the rise. Lastly, make sure your baking soda and baking powder are both fresh and active.

Storing Muffins

Store at room temperature in an airtight container. They will keep for up to 5 days.

These muffins freeze great. Make sure these are cooled completely then wrap in plastic wrap and store in a freezer bag. They will keep in the freezer for up to 3 months. Let them come to room temperature and they taste just as fresh as the day I baked them! I like to zap them in the microwave and eat them warm!

    Hi!! they do not sell chocolate chips where i stay, can i cut up a slab of milk chocolate??

    1. Sweet Basil says:

      Absolutely!

  2. Whitni @ A Cookie & A Kiss says:

    I just made these and they are SO GOOD. I made normal sized muffins and the cooking time was perfect for them! I will have to use shortening next time and see how they change! Thanks for sharing!

    1. Sweet Basil says:

      Yay! I’m so glad! Shortening just makes them softer, but I love the butter flavor. Just depends on what you’re looking for haha

  3. Khushi says:

    Hi there

    Is there any substitute for cream of Tartar?

    Thanks

    1. Sweet Basil says:

      Hi Khushi, For every 1/2 teaspoon of baking soda in the recipe, use 1 teaspoon lemon juice or white vinegar.

  4. Tessa says:

    Hi, I just tasted a warm, fresh out of the oven, muffin and it was to die for!! I asked you on IG about the cream of tartar, which we don’t have here in The Netherlands. I found online that I could also substitute it with lemonjuice. Just a teaspoon. So I did.

    I never make muffins and especially nothing chocolate because it gets to dark to quick in my oven. So I lowered the temp a bit and gave it a go. Boy oh boy did they taste good!! Your tip about heating them up in the microwave is a good one. I’ll do that.

    Oh and I sent a picture of them to my husband who was at work. He showed it to his co-workers. If I could make 20 of them for tomorrow!! Ehh maybe next time. haha.

    But anyway, to make a long story short. Sorry for that. I am a bit proud of myself that they came out so good. I’ll be maken them again. Thank you for the recipe.

    Tessa 🙂

    1. Sweet Basil says:

      I love this Tessa! You can also just use equal amounts of baking soda and baking powder instead of cream of tartar as it just helps puff the muffins and adds a little to flavor which really wont be missed. I totally have had my husband’s work ask for them too! One day I’ll send some. 🙂

  5. sara says:

    hi honey ,tnx for recipe,only i dont understand ,use cocoa powder ?

    1. Sweet Basil says:

      I sara, I’m not sure I understand your question. These muffins do call for cocoa powder and when to use it is listed in the directions.

  6. Jamie says:

    I have had this recipe printed and sitting on top of my huge pile of ripe bananas just waiting to be made and every time I walk into the kitchen I drool looking at the picture…I am crossing my fingers I can find the time to make them this weekend!

    1. Sweet Basil says:

      That’s exactly how we were through testing. The bananas would go freckly and we would all get so excited!

      1. Jamie says:

        I made these yesterday for breakfast and they were SO good. I have a few more bananas that are ripe and I will be making these again this week. Thanks and YUM!

      2. Sweet Basil says:

        Yay!! I’m so thrilled! Thanks, Jamie!
