One-Bowl Single Serve Banana Bread

When the banana bread craving hits but you don’t need a whole loaf sitting on the counter, this single serve banana bread is the answer. It bakes up in one small ramekin or mini loaf pan with just the right amount of sweet, moist crumb.

You only need one overripe banana and a handful of pantry staples. No mixer, no leftovers, and the whole thing is yours in about half an hour.

What Makes This Single Serve Banana Bread So Good

Most banana bread recipes give you a whole loaf that inevitably dries out before you finish it. This one makes exactly one generous serving. The banana itself carries the sweetness and moisture, so you don’t taste an overload of sugar.

The inside is tender with a soft, almost custardy crumb right against the center, while the top gets that classic caramelized crackle. It tastes like banana bread fresh from a bakery, but scaled just for you.

Ingredients

• 1 small overripe banana: the spottier the skin, the sweeter the bread.
• 2 tbsp brown sugar: light or dark both work; dark adds more molasses notes.
• 1 tbsp unsalted butter, melted: or use a neutral oil for a dairy-free option.
• 1 large egg, at room temperature: this helps the bread rise and hold its shape.
• ½ tsp vanilla extract: rounds out the banana flavor.
• 3 tbsp all-purpose flour: spoon and level the flour, don’t pack it.
• ½ tsp baking powder: gives the bread its lift.
• Pinch of fine sea salt: brings out the sweetness and banana taste.
• 1 tbsp chocolate chips or chopped walnuts (optional): for a little extra something on top.

Variations / Substitutions

• Sugar swaps: You can use 2 tablespoons of maple syrup or honey instead of brown sugar. The bread will be a little less domed on top but just as moist.
• Gluten-free: A 1:1 gluten-free baking blend works in place of the all-purpose flour with no other changes.
• Add some spice: Stir ¼ teaspoon of cinnamon or a scrape of fresh nutmeg into the dry mix for warmth.
• Dairy-free: Use melted coconut oil or a mild vegetable oil instead of butter. The coconut oil adds a subtle nutty note.
• For a chocolate version, try my Double Chocolate Banana Muffins.

How to Make Single Serve Banana Bread

Step 1: Mash the Banana and Mix the Wet Ingredients

Peel the banana and place it in a medium bowl. Mash it with a fork until mostly smooth, leaving a few small lumps for texture. Add the 2 tablespoons brown sugar, 1 tablespoon melted butter, 1 large egg, and ½ teaspoon vanilla extract. Whisk until the mixture is uniform and slightly frothy, about 30 seconds.

The batter will smell sweet and banana-forward. A few lumps of fruit are fine; they’ll melt into tender pockets as the bread bakes.

Step 2: Add the Dry Ingredients

Sprinkle the 3 tablespoons all-purpose flour, ½ teaspoon baking powder, and a pinch of salt directly over the bowl of wet ingredients. Use the fork to fold just until no dry streaks remain. The batter will be thick and slightly lumpy—avoid beating it smooth, or the bread will turn out dense.

Stop mixing the moment the flour disappears. A light hand keeps the crumb tender; overworking the batter develops gluten and makes the bread tough.

Step 3: Fill the Ramekin and Add Toppings

Lightly butter the inside of a 6-ounce ramekin or a small oven-safe dish (a mini loaf pan works too). Scrape the batter into the dish and level the top with the back of a spoon. If using, press a tablespoon of chocolate chips or chopped nuts lightly into the surface.

The dish should be about two-thirds full, leaving room for the bread to rise. The top will dome slightly and crackle as it bakes.

Step 4: Bake the Bread Until Golden

Preheat the oven to 350°F (175°C) if you haven’t already. Slide the filled ramekin onto the center rack and bake for 22 to 25 minutes. The top should be deeply golden and a skewer inserted into the center (avoiding any chocolate) should come out with just a few moist crumbs. The internal temp should be around 200°F (93°C) if you check.

A crack down the middle is totally normal and a sign of good banana bread. The edges will pull away from the sides of the dish, and the kitchen will fill with that caramelized banana scent.

Step 5: Cool Briefly and Dig In

Remove the ramekin from the oven and let it rest on a wire rack for 5 minutes. The bread will settle and become easier to remove. Run a small knife around the edge and tip the bread out onto a plate. It’s best eaten warm, while the top is still crackly and the center is soft.

Tips for the Best Single Serve Banana Bread

• Butter the dish generously even if it’s nonstick. The sugar in the batter can stick and tear the crust when you turn it out.
• Don’t skip the pinch of salt. It balances the sweetness and makes the banana flavor pop.
• If your banana is on the larger side, use a full 4 tablespoons of flour instead of 3 to keep the batter from getting too wet.
• For an extra crackly top, sprinkle a tiny pinch of granulated sugar over the batter just before baking.

Bake times will vary slightly depending on the shape of your dish:

Frequently Asked Questions

Can I make this single serve banana bread in the microwave?

Yes, but the texture will be more cake-like and lack a crisp crust. Microwave on high in a mug for 1 to 2 minutes, watching closely so it doesn’t overflow or dry out.

Can I use whole wheat flour?

You can, but whole wheat pastry or white whole wheat will give the best texture. All-purpose whole wheat makes the bread noticeably denser and a bit heavier.

My bread sunk in the middle, what went wrong?

This usually happens if the oven door is opened too early or the batter was overmixed. Avoid peeking until the last few minutes, and fold the flour in gently.

I don’t have a ramekin, can I use a mug?

Yes, an 8 to 10 ounce oven-safe mug works. Check it around 18 minutes, since the taller shape can bake a little faster.
