Chocolate Banana Muffins Under 100 Calories – Light, Moist, and Easy
These muffins check every box: chocolatey, tender, sweet enough to feel like a treat, and still under 100 calories each. They’re quick to make, great for meal prep, and perfect for breakfast or a midday snack. You don’t need fancy ingredients or special equipment—just a bowl, a whisk, and a muffin tin.
Use spotty bananas and pantry staples, and you’ll have a low-calorie bake that tastes like dessert but fits your goals.
Ingredients
Method
- Prep the pan and oven: Preheat the oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or lightly grease the cups. Liners help with portion control and clean release.
- Mash the bananas: In a large bowl, mash the bananas until mostly smooth. A few small lumps are fine and add texture.
- Whisk in the wet ingredients: Add the egg, Greek yogurt, oil, sugar, and vanilla. Whisk until the mixture looks creamy and well combined.
- Combine the dry ingredients: Sprinkle the flour, cocoa powder, baking powder, baking soda, and salt over the wet mixture. Gently fold with a spatula until just combined. Do not overmix.
- Add optional chips: If using mini chocolate chips, fold them in now. Reserve a few to sprinkle on top for a bakery-style look.
- Portion the batter: Divide evenly among the 12 muffin cups. The cups should be about two-thirds full.
- Bake: Bake for 12–15 minutes, or until the tops spring back lightly and a toothpick comes out with a few moist crumbs (not wet batter).
- Cool: Let muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely. This helps set the crumb and keeps them tender.
What Makes This Recipe So Good
- Under 100 calories each: You get the chocolate fix without blowing your day. Great for portion control and packed lunches.
- Moist and tender: Mashed banana and a touch of yogurt keep the crumb soft without a lot of oil or butter.
- One-bowl friendly: Quick to mix, easy to clean up, and hard to mess up.
- Naturally sweetened: Ripe bananas bring sweetness, so you’ll use far less sugar than most muffins.
- Customizable: Add mini chocolate chips, nuts, or spices and still keep calories in check.

How to Make It
- Prep the pan and oven: Preheat the oven to 350°F (175°C).
Line a 12-cup muffin tin with paper liners or lightly grease the cups. Liners help with portion control and clean release.
- Mash the bananas: In a large bowl, mash the bananas until mostly smooth. A few small lumps are fine and add texture.
- Whisk in the wet ingredients: Add the egg, Greek yogurt, oil, sugar, and vanilla.
Whisk until the mixture looks creamy and well combined.
- Combine the dry ingredients: Sprinkle the flour, cocoa powder, baking powder, baking soda, and salt over the wet mixture. Gently fold with a spatula until just combined. Do not overmix.
- Add optional chips: If using mini chocolate chips, fold them in now.
Reserve a few to sprinkle on top for a bakery-style look.
- Portion the batter: Divide evenly among the 12 muffin cups. The cups should be about two-thirds full.
- Bake: Bake for 12–15 minutes, or until the tops spring back lightly and a toothpick comes out with a few moist crumbs (not wet batter).
- Cool: Let muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely. This helps set the crumb and keeps them tender.
How to Store
- Room temperature: Store in an airtight container for up to 2 days.
Place a paper towel in the container to absorb moisture.
- Refrigerator: Keep up to 5 days in a sealed container. Warm in the microwave for 10–15 seconds to soften.
- Freezer: Freeze on a sheet pan until solid, then move to a freezer bag. They keep well for up to 3 months.
Thaw at room temp or microwave in 20-second bursts.
Health Benefits
- Calorie control: Each muffin sits under 100 calories, which makes snack planning simpler and helps with overall energy balance.
- Fiber and potassium: Bananas provide potassium for muscle and heart function, plus fiber for digestion and satiety.
- Protein boost: Greek yogurt and egg add a small but meaningful amount of protein to support fullness.
- Better-for-you fats: A small amount of avocado or olive oil supports texture and mouthfeel without heavy saturated fat.
- Cocoa perks: Unsweetened cocoa powder brings rich flavor and contains flavanols, which have antioxidant properties.
Pitfalls to Watch Out For
- Unripe bananas: Green or just-yellow bananas won’t be sweet enough, and your muffins will taste flat. Use very spotty bananas for best flavor and moisture.
- Overmixing: Stirring too much develops gluten and can make muffins tough. Fold gently until the flour disappears.
- Overbaking: A few extra minutes can dry out low-fat muffins quickly.
Start checking at 12 minutes.
- Portion creep: If you overfill the cups, you’ll get fewer muffins and higher calories per serving. Use a level scoop for even portions.
- Hidden add-ins: Big handfuls of chocolate chips or nuts can push calories over 100 fast. Stick to mini chips or measure carefully.
Recipe Variations
- Extra chocolatey: Stir in 1 tablespoon espresso powder with the dry ingredients to deepen the cocoa flavor without extra calories.
- Nutty swirl: Add 2 tablespoons powdered peanut butter to the dry mix and a few drops of water to activate.
It adds flavor with minimal calories.
- Spiced banana: Fold in 1 teaspoon cinnamon and a pinch of nutmeg. Warm spices make the muffins taste richer.
- Oat twist: Swap 1/4 cup of the flour for quick oats. The texture becomes heartier, with a slight bump in fiber.
- No added sugar: Skip the granulated sugar and use an equal measure of a zero-calorie sweetener that bakes well.
Taste the batter and adjust to preference.
- Dairy-free: Use a dairy-free yogurt (unsweetened) and choose oil instead of butter. Check that your chocolate chips are dairy-free if adding.
- Gluten-free: Use a 1:1 gluten-free baking blend. Let the batter rest 5 minutes before baking to hydrate the flours.
FAQ
How do I keep these under 100 calories?
Use standard muffin cups and divide the batter evenly into 12 portions.
Stick to the ingredient list as written, measure accurately, and avoid large add-ins. If you add chocolate chips, keep it to 2 tablespoons total.
Can I use frozen bananas?
Yes. Thaw them fully and drain any excess liquid before mashing.
Frozen bananas tend to be sweeter and work great in baking.
Can I replace the sugar with honey or maple syrup?
You can, but reduce the yogurt slightly to keep the batter from getting too wet. Start by swapping 1/3 cup sugar for 1/4 cup honey or maple and remove 1 tablespoon yogurt. Calories will shift slightly.
Why did my muffins sink in the middle?
They may have been underbaked or the batter was overmixed.
Also check that your baking powder and baking soda are fresh. Old leaveners lose power and affect rise.
Can I make them as mini muffins?
Yes. Bake in a mini muffin pan for 8–10 minutes, checking early.
You’ll get more servings, and each mini will be lower in calories.
Do they taste like “diet” muffins?
No. The bananas and cocoa bring real flavor, while yogurt keeps them moist. They’re lighter than bakery muffins, but still chocolatey and satisfying.
What’s the best way to reheat?
Microwave a muffin for 10–15 seconds.
It refreshes the crumb and brings back the chocolate aroma without drying them out.
Can I add protein powder?
Yes, but swap it for some flour, not in addition to it. Replace up to 1/4 cup flour with a whey or plant protein designed for baking. You may need a tablespoon more yogurt if the batter is dry.
Final Thoughts
These Chocolate Banana Muffins prove you don’t need heavy ingredients to get a rich, chocolatey bite.
With simple pantry staples and ripe bananas, you can bake a batch in under 30 minutes and keep your snacks on track. They freeze well, pack easily, and taste great warmed up with a cup of coffee. Keep a few on hand for busy mornings or late-night cravings—no second-guessing and no sacrifice on flavor.
