Why I Love This Recipe

I’m a big believer in getting maximum flavor with minimum effort, and this microwave banana condensed milk cake absolutely delivers on that front. What’s not to love about a cake that goes from ingredients to indulgence in less than 10 minutes? The condensed milk creates an incredibly tender crumb and a rich, sweet flavor that’s utterly addictive. Plus, it’s a fantastic way to use up those ripe bananas that are too soft for snacking but perfect for baking. It’s truly a game-changer for instant gratification.

Ingredients

Here’s what you’ll need for this speedy sweet treat:

• 1 ripe banana, mashed
• 1/4 cup all-purpose flour
• 1/4 teaspoon baking powder
• 2 tablespoons sweetened condensed milk
• 1 tablespoon vegetable oil (or melted butter)
• 1/4 teaspoon vanilla extract
• Pinch of cinnamon (optional, but recommended for warmth)
• Pinch of salt

Swaps and Notes

• Banana: The riper, the better! Brown spots mean more sweetness and a softer texture, perfect for mashing. If you don’t have a very ripe banana, a less ripe one will work, but the banana flavor might be less pronounced.
• Flour: While all-purpose is standard, you can experiment with 1:1 gluten-free flour blends. I haven’t tested this with whole wheat flour, but it might make the cake a bit denser.
• Sweetened Condensed Milk: This is key to the cake’s moisture and sweetness. Do not substitute with evaporated milk or regular milk, as the consistency and sugar content are completely different.
• Oil/Butter: Vegetable oil keeps the cake super moist. Melted butter adds a lovely richness if you prefer that flavor profile.
• Add-ins: Feel free to toss in a tablespoon of mini chocolate chips for an extra layer of indulgence. Or, a few chopped nuts like walnuts or pecans would be delicious.
• Serving Size: This recipe is designed for a single serving, perhaps two if you’re sharing small portions. You can double it, but make sure to use a larger microwave-safe mug or ramekin and adjust the cooking time accordingly.

Steps for the Recipe

Ready to bake? Let’s get this cake going!

1. Prepare the Banana: In a microwave-safe mug (a 12-14 ounce mug works best), mash the ripe banana with a fork until mostly smooth. A few small lumps are perfectly fine.
2. Add Wet Ingredients: Stir in the sweetened condensed milk, vegetable oil (or melted butter), and vanilla extract until well combined with the mashed banana.
3. Mix Dry Ingredients: Add the all-purpose flour, baking powder, optional cinnamon, and pinch of salt to the mug. Stir gently until just combined. Be careful not to overmix; a few small lumps of flour are okay. Overmixing can lead to a tough cake.
4. Microwave: Place the mug in the microwave. Cook on high for 1 minute to 1 minute 30 seconds. Cooking times can vary based on your microwave’s wattage. Start with 1 minute and then add 15-second increments until the cake is set and springs back lightly when touched. The top might look a little wet, but the cake should be cooked through.
5. Cool Slightly & Serve: Carefully remove the mug from the microwave (it will be hot!). Let the cake cool in the mug for a minute or two before digging in.

Tips for Success

• Don’t Overmix: Seriously, this is one of the biggest pitfalls for microwave cakes. Mix until just combined to keep it tender.
• Know Your Microwave: Microwave wattages vary wildly. It’s always best to start with the lower end of the cooking time and add more as needed. An overcooked microwave cake can become dry and rubbery.
• Use the Right Mug: A larger mug prevents overflow and allows the cake to cook more evenly.
• Don’t Overcook: The cake will continue to cook slightly as it cools in the mug. It’s better to undercook by a few seconds than overcook.

Serving Suggestions and Pairings

This Microwave Banana Condensed Milk Cake is fantastic on its own, but you can elevate it with a few simple additions. A dollop of whipped cream, a scoop of vanilla ice cream, or a drizzle of caramel sauce takes it to the next level. For a delightful breakfast or brunch treat, pair it with a refreshing glass of This Blueberry Lemonade Is My Favorite Refreshing Drink for Sunny Days. If you’re leaning into the dessert vibe, consider it alongside a small serving of These Chocolate Chip Cookie Dough Brownie Bombs Are My Favorite Sweet Obsession for a truly decadent spread.

Storage and Leftover Tips

Honestly, this cake is best enjoyed immediately. It’s designed to be a single-serving treat. If you do have a tiny bit leftover, you can cover the mug with plastic wrap and refrigerate it for up to a day. Reheat briefly in the microwave for 10-15 seconds if you want it warm again, but the texture won’t be quite as fresh as when it’s first made.
