This single serve banana bread is moist, fluffy, and baked in just one ramekin or mug, making it the perfect quick treat when you have one ripe banana and a craving to satisfy.

You know that one banana sitting on your counter, past its prime, spotted and soft and just a little too sweet to eat on its own? Do not throw it away. That banana is basically begging to become this single serve banana bread, and it will take you less than 30 minutes from start to finish.
This recipe was built for moments when you want something warm, homemade, and genuinely satisfying without baking an entire loaf you will spend a week eating. It is one of the best sweet breakfast ideas for one, a perfect fast and healthy dessert, and honestly one of the most comforting little bakes you can pull off on a Tuesday morning or a late Sunday afternoon.
The result is a beautifully golden mini loaf with a soft, moist crumb, real banana flavor, and just enough sweetness to feel like a treat without going overboard. It bakes right in a ramekin, requires almost no cleanup, and comes together in a single small bowl. This is single serve baking at its finest.
Before you start, a quick note on tools and ingredients. A 6-ounce oven-safe ramekin is really the ideal vessel here because it gives the bread the right depth to rise properly and develop that lightly golden top. The quality of your vanilla extract and the ripeness of your banana will make a noticeable difference in the final flavor, so do not skip on either.
One of the most common questions people search for is what to make with a banana when they only have one left. Banana bread is the classic answer, but most recipes call for three or four bananas and yield an entire loaf. This recipe flips that entirely. One banana is not a limitation here; it is the whole point.
A single very ripe banana provides the perfect amount of natural sweetness, moisture, and that deep, caramelized banana flavor that makes banana bread so craveable. The riper it is, the better. Think dark yellow with lots of brown spots. If the peel is more brown than yellow, you are in the sweet spot.
Chef's Tip: If your banana is not quite ripe enough, place it unpeeled on a baking sheet and roast it at 300 degrees F for 15 to 20 minutes until the skin turns black. Let it cool, then scoop out the softened flesh. It concentrates the sugars beautifully and works perfectly in this recipe.
Single serve baking recipes can be tricky because the margin for error is smaller than in a full batch. Here is what makes this one consistently great:
If you want to fold in mix-ins, mini chocolate chips, crushed walnuts, or a pinch of nutmeg all work beautifully. This is a very forgiving little recipe that welcomes small riffs.
For anyone looking for healthy recipes with one banana or fast and healthy desserts, this one checks a lot of boxes. Banana provides natural sugar and potassium, the egg yolk adds protein and healthy fats, and the overall portion is built for one so there is no temptation to cut a second slice. Swap the granulated sugar for coconut sugar or reduce it by half if you want something even lighter. The banana carries enough sweetness on its own that it still tastes great.
This is the kind of one banana dessert you can feel good about eating for breakfast, a mid-afternoon snack, or a late-night treat without going overboard.
Ready to bake? Here is everything you need in one place:

This single serve banana bread is moist, fluffy, and baked in just one ramekin or mug, making it the perfect quick treat when you have one ripe banana and a craving to satisfy.
Preheat your oven to 350 degrees F (175 degrees C). Lightly grease a 6-ounce ramekin or a small oven-safe mug with butter or nonstick spray.
In a small bowl, mash the ripe banana thoroughly with a fork until smooth with very few lumps.
Add the melted butter, sugar, egg yolk, and vanilla extract to the mashed banana. Stir until well combined.
Sprinkle in the flour, baking powder, cinnamon, and salt. Stir gently until just combined. Do not overmix or the bread will turn out dense and tough.
Pour the batter into your prepared ramekin. Tap it gently on the counter once or twice to settle the batter. Scatter mini chocolate chips on top if using.
Bake for 20 to 24 minutes, until the top is set and golden and a toothpick inserted into the center comes out with just a few moist crumbs.
Let the banana bread cool in the ramekin for at least 5 minutes before eating. Enjoy warm straight from the dish or run a knife around the edge and turn it out onto a plate.
The best way to serve this is warm, straight from the ramekin with a small pat of salted butter melting over the top. If you want to get fancy, a drizzle of honey or a spoonful of peanut butter takes it somewhere really special.
Because this is a 1 banana recipe sized for one person, leftovers are unlikely, but if you do have some, cover the ramekin with plastic wrap and keep it at room temperature for up to a day or in the refrigerator for up to three days. A quick 25-second blast in the microwave brings it right back.
Want to double it? Simply double every ingredient and bake in two ramekins side by side. The bake time stays the same. This is a great trick when you want to make a sweet little breakfast for two without the commitment of a full loaf.
Whether you are new to single serve baking recipes or just trying to figure out the best baking ideas with bananas, this one belongs in your regular rotation. It is fast, it is cozy, and it makes you feel like a genius for turning one sad banana into something genuinely delicious.
