Last summer my cousin walked into my kitchen with three overripe bananas and said we needed to make something that tasted like our childhood trips to the ice cream shop. We ended up with these cupcakes, and the way they made the whole house smell like warm banana bread had both our roommates wandering in from different parts of the house.
I brought these to a friend's birthday party last month and watched her face light up when she took her first bite. She texted me the next morning asking for the recipe because her husband kept talking about them in his sleep.

Pin it These cupcakes have become my go to whenever someone needs a pick me up. There is something about the combination of warm banana cake and creamy frosting that feels like a hug in food form.
Making Banana Milk
For the most authentic milkshake flavor blend a few slices of ripe banana with milk until completely smooth. This trick makes the frosting taste like it came straight from a 1950s soda fountain.
Frosting Secrets
Adding mashed banana directly to the frosting gives it an intense flavor but it will make the frosting slightly softer. If you plan to pipe elaborate designs keep the banana in the milk only or add a bit more powdered sugar to stabilize it.
Fun Variations
These cupcakes are incredibly forgiving and welcome all kinds of creative twists.
- Fold a handful of mini chocolate chips into the batter before baking
- Toast the cupcake tops lightly under the broiler for a minute before frosting
- Swap the vanilla extract for almond extract in the frosting for a nutty note

Recipe FAQs
- → Can I use frozen bananas for these cupcakes?
-
Yes, frozen bananas work perfectly once thawed and drained. They may actually provide a more intense banana flavor since freezing concentrates the natural sweetness. Just ensure they're fully thawed and excess liquid is removed before mashing.
- → How should I store these frosted cupcakes?
-
Store frosted cupcakes in an airtight container at room temperature for up to 2 days. For longer storage (up to 5 days), refrigerate them but bring to room temperature before serving for the best texture and flavor.
- → Can I make these cupcakes ahead of time?
-
Absolutely! Bake the cupcakes up to 2 days in advance and store unfrosted in an airtight container. Frost them the day of serving for the freshest appearance and texture. The frosting can also be prepared ahead and stored in the refrigerator.
- → What can I substitute for banana milk?
-
Regular whole milk works beautifully as a substitute. For extra banana flavor, blend a few banana slices with your milk until smooth, or use banana-flavored milk if available. The frosting will still be creamy and delicious.
- → Why did my cupcakes turn out dense?
-
Overmixing the batter can create dense cupcakes. Mix just until the dry ingredients are incorporated—some small lumps are perfectly fine. Also ensure your butter is properly softened and your leavening agents are fresh for the best rise.
- → Can I freeze these cupcakes?
-
Yes! Freeze unfrosted cupcakes in an airtight container or freezer bag for up to 3 months. Thaw at room temperature before frosting. Frosted cupcakes can also be frozen, though the garnish toppings are best added fresh after thawing.
