Warm banana mug cake in the air fryer is my quick fix for dessert cravings when I want something cozy but have barely any time or energy. Built for those moments when a ripe banana is staring at you from the counter, this single-serve treat delivers sweet comfort and just the right amount of chocolate.
I first tried this on a busy Tuesday night and was amazed at how perfectly fluffy it turned out—now it is my shortcut to a dessert that feels special with barely any work.
Ingredients
- Banana: select a banana with plenty of brown spots which means extra sweetness and intense flavor
- Flour: regular all purpose flour works but you can use whole wheat for a heartier finish
- Baking powder: ensures fluffiness and rise—check that it is fresh for best results
- Maple syrup: brings natural sweetness with a caramel-like finish
- Milk: a splash helps the cake stay moist dairy or non dairy both work well
- Walnuts: give satisfying crunch and a hint of bitterness that balances the sweetness
- Chocolate chips: use your favorite brand for melty chocolate pockets I recommend chopping a chocolate bar if you want extra gooey bites
Step-by-Step Instructions
- Mash the Banana:
- Start by mashing half a banana in the bottom of a twelve ounce mug until completely smooth which helps the cake texture
- Mix the Batter:
- Add flour baking powder maple syrup and milk to the mug Whisk until smooth and no dry spots remain
- Fold in Extras:
- Gently fold in walnuts and half the chocolate chips Try to distribute them evenly without deflating the batter
- Air Fry the Cake:
- Place the mug into your air fryer Set to three hundred fifty degrees Fahrenheit Bake for six to eight minutes until the center feels set and springs back gently when touched
- Finish and Serve:
- Remove from air fryer Sprinkle the rest of the chocolate chips on top Let cool for one to two minutes before enjoying

Storage Tips
Mug cakes are best enjoyed right away while still warm but if you need to make ahead you can cover and store in the fridge for a day Reheat quickly in the air fryer or microwave though the texture is never quite the same as fresh
Ingredient Substitutions
- No walnuts Swap for pecans or skip for a nut-free version
- No maple syrup Use honey or agave or even brown sugar for a different kind of sweetness
- Out of regular milk Any plant milk like almond or oat will do
Serving Suggestions
Top with whipped cream a scoop of vanilla ice cream or a drizzle of peanut butter for an extra treat I love eating it straight from the mug or scooping it into a bowl for easier sharing
