Hi there! I don’t know about you, but sometimes I just need something sweet, warm, and comforting—without making a whole mess in the kitchen. That’s how this 5-minute banana bread in a mug became one of my favorite little treats. It’s fast, it’s soft, and it tastes like something that took way more effort than it really did.
I started making this when I had one lonely banana getting too ripe and I didn’t feel like baking a full loaf. One mug, a fork, a few pantry staples, and boom—you’ve got yourself a cozy dessert (or even breakfast). And trust me, once you try it, you’ll want to keep a banana on standby just for this.
Why You’ll Love This Mug Banana Bread
This recipe checks all the boxes for me, and I think it will for you too:
- Quick & fuss-free: All done in one mug, no fancy tools, and ready in minutes.
- Perfect portion: Just enough for one person—so you won’t be tempted to eat a whole loaf.
- Super customizable: Want it sweeter? Add honey. Feeling chocolatey? Toss in some chips.
- No oven needed: All you need is a microwave.
Whether it’s a late-night snack, a rainy morning breakfast, or just a mini reward after a long day—this little mug cake has your back.
Make It Your Way: Easy Ingredient Swaps
This recipe is already simple, but it also gives you room to be creative or adjust based on what you have at home:
- No ripe banana? Use 1/4 cup unsweetened applesauce instead.
- Need it dairy-free? Swap the butter for coconut oil or vegetable oil.
- No egg? Make a flax egg: 1 tbsp ground flaxseed + 2.5 tbsp water.
- Want less sugar? Use honey, maple syrup, or a sugar-free sweetener.
- Going gluten-free? A gluten-free flour blend works well here—just make sure it has xanthan gum.
It’s honestly a recipe that doesn’t mind a little change. I’ve tried it all kinds of ways and it still turns out great!
How to Make Banana Bread in a Mug
This is the fun part. Let me walk you through how I make mine.
Ingredients:
- 1 ripe banana, mashed
- 1 tablespoon melted butter or coconut oil
- 1 egg
- 3 tablespoons all-purpose flour
- 2 tablespoons brown sugar or honey
- 1/4 teaspoon baking powder
- Pinch of salt
- 2 tablespoons chocolate chips (optional)
- 2 tablespoons chopped walnuts (optional)
Instructions:
1. Mash the Banana:
In a large microwave-safe mug, mash your ripe banana with a fork until smooth.
2. Add Butter:
Stir in the melted butter or coconut oil. It should start to look creamy.
3. Crack in The Egg:
Mix in the egg until it’s all combined—no streaks!
4. Dry Ingredients Next:
Add the flour, brown sugar or honey, baking powder, and a pinch of salt. Stir everything together until you get a smooth batter.
5. Toss in Extras:
If you’re adding chocolate chips or nuts, now’s the time to gently stir them in.
6. Microwave it:
Place the mug in the microwave and cook on high for about 1 minute and 30 seconds. If it still looks a bit wet in the center, microwave in 15-second intervals until done.
7. Cool & Enjoy:
Let it cool for a minute (it’ll be hot!), then grab a spoon and enjoy! Sometimes I add a tiny drizzle of peanut butter or sprinkle of sea salt—just saying.
Microwave Tips: Get It Just Right
I’ve made this more times than I can count, and here are a few things I learned:
- Use a big mug: The batter puffs up while cooking, so you want a mug with room.
- Don’t overcook: Too long in the microwave = dry banana bread. Start with 1:30, then add a few seconds if needed.
- Cool it down: Let it sit for a minute. It helps the texture settle and keeps you from burning your mouth!
- Top it up: A spoonful of vanilla yogurt or a swirl of peanut butter takes this to the next level.
Answers to Questions You Might Have
What if my banana isn’t ripe?
No worries! You can soften it quickly by microwaving it (just the banana, unpeeled) for about 30 seconds. Let it cool before mashing.
Can I make it vegan?
Absolutely. Skip the egg and use a flax egg or a spoonful of applesauce. Swap butter for coconut oil, and you’re good to go.
How do I store leftovers?
Honestly, I usually don’t have leftovers… but if you do, cover the mug and store it in the fridge for up to 2 days. Microwave for 30 seconds to reheat.
Can I use other flours?
Yes! Try almond flour or a gluten-free blend. Just know the texture might change a bit, and you may need to cook a little longer.
