Banana Chocolate Swirl Muffins – Moist, Sweet, and Easy to Make

Velvety Banana-Chocolate Harmony Muffins
Ingredients
Method
- Preheat your oven to 350°F (if using a dark-coated tin, lower to 325°F). Line a muffin tin with paper liners. (This batch makes about 18 muffins so bake in two rounds if needed.)
- In a large mixing bowl, combine mashed bananas, granulated sugar, brown sugar, oil, sour cream, eggs, and vanilla. Whisk until the mixture is smooth and well blended.
- Add the flour, baking powder, salt, and baking soda. Stir gently just until there are no dry pockets remaining. (It’s perfectly fine if your batter remains a bit lumpy.)
- For the chocolate component, whisk together cocoa powder and boiling water in a medium bowl until the mixture is velvety smooth. Then, carefully fold in about 1 1/4 cups of the banana batter into the cocoa mixture. Mix gently until fully incorporated but do not over mix.
- Layer the batters into each muffin cup as follows: spoon approximately 1 1/2 tablespoons of regular banana batter, followed by a scant 1 tablespoon of chocolate batter, then another 1 1/2 tablespoons of the plain batter, and finally finish with a teaspoon more of chocolate batter. (Remember, you’re layering, not stirring!)
- If desired, lightly dust the tops with coarse sugar before baking.
- Bake for 17-19 minutes, or until the muffin tops spring back when lightly pressed. Remove from the tin and let them cool completely on a wire rack.

Savor the fusion of moist banana cake-like muffins intertwined with luscious chocolate ribbons!
Imagine a classic banana bread transformed into an irresistible muffin, delicately accented with streaks of rich chocolate. These muffins are as stunning as they are simple to prepare – a must-try for anyone with a sweet tooth!
A Clever Dual-Batter Technique
To create the enchanting swirls of chocolate inside the banana muffins, you’ll prepare two batters – one for the base and one for the chocolate twist. Instead of starting two batters from scratch, here’s a smart shortcut:
- Make your regular banana muffin batter in one bowl following the simple, one-bowl method.
- In another bowl, blend the cocoa powder with boiling water until smooth.
- Add a portion of the banana batter (about 1 1/4 cups) to the chocolate mixture and stir gently.
Now you have two flavors ready to layer into beautifully unique muffins!




Assembling Your Layered Muffins
Here are a few things to keep in mind as you fill your muffin cups:
- Keep it simple. The layers don’t have to be perfect; the beauty is in their artisanal look!
- Portion wisely. Each muffin cup should hold roughly ¼ cup of combined batter. Adjust based on your tin’s size.
- Layer sequence. Aim for a base of plain batter, then a layer of chocolate, followed by more plain batter, and finish with a dollop of chocolate on top.
- Extra batter? If you have a little extra, simply add small dollops evenly until each cup is about equally filled.
- No swirling! Resist the urge to mix the two batters together – the defined layers create the best visual and flavor contrast.
Remember: Even if your muffin cups vary slightly in batter amount, they’ll taste amazing every time!
