📝 Ingredient Notes
A full list of ingredients, quantities, and instructions are located in the recipe card at the end of the post.
- Banana: Use very ripe bananas. For this recipe I used three large ripe banana, which is around 1 ½ cups of mashed bananas. If you don't have ripe bananas but would like to make this cake, see notes below for how to ripen bananas quickly.
- Flour: All purpose flour gives this cake the best crumb. Use a scale when measuring to get the best results.
- Leaveners: Both baking powder and baking soda are used to help the muffins rise.
- Espresso powder: The secret to these delicious muffins is the espresso powder. It gives it hints of flavor, without it being overpowering. It also complements the chocolate and bananas very well.
- Salt: Always needed in cake.
- Sugar: I use both brown sugar as well as granulated sugar.
- Oil: Vegetable or any neutral oil.
- Eggs: Room temperature, large eggs.
- Sour cream: Just a little sour cream for extra moisture in these muffins.
- Chocolate: I like to use chopped chocolate, but you could use chocolate chips as well. I would suggest using mini chocolate chips.
See recipe card for quantities.
🍴Special Equipment
Kitchen Scale: It's so important to use a kitchen scale for accurate results.
Cupcake pan: You'll need cupcake/muffin pan.
Mixing bowls: I love using glass Mixing Bowls when making batters and doughs.
⇄ Substitutions
Neutral oil - You can use any type of neutral oil, from vegetable, canola, avocado, or even a light olive oil.
Yogurt - if you don't have any sour cream on hand, you can substitute it for full fat greek yogurt
Chocolate - Instead of chocolate chunks, swap it for mini chocolate chips.
✨ Variations
Nuts - Add some walnuts or pecans for an extra crunch and more texture.
Spices - Add a touch of cinnamon and nutmeg, or any other spices you like to add to your banana muffins, like my Spiced Banana Cake.
Streusel - You could jazz it up with a streusel on top before popping it into the oven.
Turbinado sugar - Sprinkle some turbinado sugar on top before baking for an extra crunch and sweetness.

Step 1
In a medium bowl, combine flour, baking soda, baking powder, salt, espresso powder, and chocolate chunks and whisk until completely combined.
💡 Hint: If you don't have any ripe bananas but want to make this recipe, bake bananas on a lined baking sheet at 350 degrees F. for about 15 minutes until the peels are black. Let them cool, then peel and scoop out the bananas.

💡Pro Tips
Measure Flour Correctly - As always, with any recipe, use a kitchen scale, as it is the best form of measuring your ingredients. If you don't have a kitchen scale, fluff your flour, scoop flour with a spoon into a measuring cup and level off.
Don't over mix: Once the dry ingredients are incorporated, stop mixing.
High temperature - Don't skip this step! Bake for 7 minutes at high temperature to get taller muffins, with tender and moist centers.
Lower the temperature - Don't forget to lower the temperature after the initial 7 minutes. Otherwise, your muffins could burn.
Fill the liners - Make sure to fill the liners (as shown in the picture). This batter is enough for 12 muffins, and it doesn't create any issues or messes to fill them up to the top of the liner.
Ripe bananas - If you don't have any ripe bananas but want to make this recipe, bake bananas on a lined baking sheet at 350 degrees F. for about 15 minutes until the peels are black. Let them cool, then peel and scoop out the bananas.
❄ Storage
Room Temperature - Store these Banana Chocolate Chunk Muffins in an airtight container for about 3 days.
Freezer - You can wrap them individually, then store them in the freezer for about 2-3 months.
