Desserts
This banana cake recipe without egg in microwave delivers a moist, tender crumb with no baking experience required—just mix, microwave, and enjoy. The secret lies in a simple substitution (applesauce or yogurt) that replaces eggs while keeping the texture light and fluffy. I developed this method after realizing most microwave cakes either turn rubbery or require eggs, so I set out to create a foolproof version that actually tastes homemade.
The beauty of this microwave method is its simplicity: no preheating, no oven mess, and just 5 minutes of active time. You’ll use ripe bananas for natural sweetness, a touch of baking powder for lift, and a splash of vanilla to deepen the flavor. The microwave does the heavy lifting, ensuring even cooking without drying out the cake—something traditional microwave recipes often struggle with.
What you’ll end up with is a single-serving cake that’s perfectly moist on the inside with a lightly golden top, all without cracking or sinking. The texture stays soft for days, making it ideal for breakfast, dessert, or an afternoon pick-me-up. Best of all, it’s vegetarian, egg-free, and ready in under 10 minutes—no waiting for an oven to preheat.
This recipe works equally well as a quick treat or a last-minute dessert for guests. Serve it warm with a dollop of whipped cream or a drizzle of honey for extra indulgence. Let’s make this cake—your microwave is about to become your new baking shortcut.
Ingredients for banana cake recipe without egg in microwave
Five ripe bananas and a handful of pantry staples transform into a moist microwave cake.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 1 ½ cups | Mashed to remove lumps |
| All-Purpose Flour 🌾 | 1 cup | Sifted for light texture |
| Granulated Sugar 🍚 | ¾ cup | White or brown preferred |
| Unsweetened Applesauce 🍎 | ½ cup | Replaces eggs for moisture |
| Vanilla Extract 🌿 | 1 tsp | Pure extract preferred |
| Baking Powder 🧂 | 1 tsp | Aluminum-free recommended |
| Salt 🧂 | ¼ tsp | Fine sea salt preferred |
| Vegetable Oil 🫒 | ¼ cup | Light or canola oil |
| Plain Yogurt 🥛 | ¼ cup | Unflavored, full-fat preferred |
| Vanilla Yogurt 🍦 | ¼ cup | For extra flavor depth |
| Chopped Walnuts 🌰 | ¼ cup | Optional for crunch |
| Powdered Sugar 🍚 | 2 tbsp | For dusting top |
The bananas are the star here—ripe with brown spots means natural sweetness and moisture. Trader Joe's or local markets usually have the best selection of perfectly ripe bananas. If yours are too firm, let them sit at room temperature overnight. The yogurt adds richness without eggs, so full-fat Greek yogurt gives the best texture, but regular plain yogurt works too. For the flour, King Arthur or Bob's Red Mill brands are my go-to—they bake up lighter. Sift it first to avoid dense cake. The baking powder needs to be fresh, so check the expiration date if you've had it a while.
No applesauce? Unsweetened pumpkin puree works at the same amount. Out of yogurt? Dairy-free yogurt or extra applesauce keeps it vegan—just reduce the applesauce by 2 tbsp first. The walnuts are optional, but if you skip them, add another 1 tbsp of powdered sugar for sweetness. For a chocolate twist, swap 2 tbsp of the all-purpose flour for cocoa powder. The vanilla extract should be pure—imitation won't give the same depth. If you're using brown sugar, pack it tightly into the measuring cup for accurate measurement.
This cake stays moist for 3-4 days at room temperature, wrapped tightly in plastic. For longer storage, refrigerate for up to 1 week—the texture actually improves after 24 hours. Microwave-safe mugs work best, but if yours isn't ideal, use a small oven-safe dish instead. The powdered sugar topping keeps for 2 weeks in an airtight container. Double the recipe for a loaf pan—just bake it in the microwave in 2-minute intervals until fully cooked.

Step-by-step instructions for banana cake without egg in microwave
Here's how to make a perfectly moist banana cake in minutes—no eggs, no oven, just pure convenience.
Mash the Bananas Thoroughly
In a large microwave-safe bowl, mash the 1.5 cups ripe bananas until completely smooth with no visible lumps. I like to use a fork first to break them up, then press through a fine-mesh sieve if needed—this ensures an ultra-smooth batter that won't leave gummy spots in your cake. The riper the bananas, the sweeter and more flavorful your cake will be.
Add the 0.5 cup unsweetened applesauce and mix well. The applesauce replaces eggs perfectly, adding moisture and structure without any eggy taste. Stir in the 0.25 cup vegetable oil, 0.25 cup plain yogurt, and 0.25 cup vanilla yogurt until fully combined. This wet mixture should be thick but pourable—like a slightly heavy pancake batter. If it looks too thick, add 1 tablespoon water to loosen it.
Combine Dry Ingredients
In a separate bowl, whisk together the 1 cup all-purpose flour, 0.75 cup granulated sugar, 1 teaspoon baking powder, and 0.25 teaspoon salt. Sift the flour first if possible—this prevents lumps and gives you that light, airy texture we're after. The baking powder is crucial here; it's what makes your cake rise properly in the microwave.
Gradually fold the dry ingredients into the wet mixture using a spatula, mixing just until combined. Overmixing develops gluten, which can make your cake dense. Stop mixing as soon as you see no more flour streaks remaining. If using, fold in the 0.25 cup chopped walnuts at this stage—they'll add a nice crunchy contrast to the soft cake.
Microwave in Short Bursts
Pour the batter into a greased 8-inch round microwave-safe dish or a standard coffee mug if you're making individual servings. Microwave on high power for 60 seconds, then pause to check. The edges should be set but the center should still look slightly underdone—this is normal and necessary for even cooking.
Return the cake to the microwave and cook in 30-second intervals, checking after each burst. You're looking for a cake that springs back slowly when gently pressed in the center (about 2-3 minutes total). Overcooking is easy in the microwave, so it's better to slightly undercook and let it finish steaming off the heat. The cake will continue cooking for a minute or two after you remove it.
Cool and Finish
Let the cake cool in the dish for 5 minutes—this prevents it from crumbling when you try to serve it. While it cools, dust the top generously with 2 tablespoons powdered sugar using a fine-mesh sieve. This adds a beautiful finish and balances the natural sweetness of the bananas. The powdered sugar also helps create that classic cake texture on the surface.
For best results, serve the cake warm. The microwave method keeps the cake incredibly moist, almost like a warm, spongy pudding. Each slice should be tender with just the right amount of banana flavor, and those walnuts (if used) will add a delightful crunch. Store leftovers in an airtight container for up to 3 days—though I doubt they'll last that long!
Pro Tips For Making Banana Cake Recipe Without Egg In Microwave
- Mash Bananas Thoroughly: I learned this the hard way—lumpy banana puree means a dense, uneven cake. Use a fork first to break up clumps, then press through a fine-mesh sieve if you’re impatient (yes, even if you’re in a hurry). No sieve? A potato masher works, but straining removes stubborn fiber that’ll make your cake gummy.
- Mix Dry Ingredients First: Combine flour, sugar, and baking powder before adding wet ingredients—this avoids overmixing and keeps the texture tender. I used to dump everything in at once, and my cakes always turned out tougher than they should’ve. A quick whisk for 10 seconds is all you need.
- Microwave in 30-Second Bursts: Start with 30 seconds at 80% power, then check immediately—microwaves vary wildly. Overcooking turns this cake rubbery fast. If it’s not set after the first interval, add 15-second increments. Covering with a damp paper towel helps, but don’t skip the checks.
- Use Warm Applesauce: Heat the applesauce in the microwave for 20 seconds before mixing—it blends smoother and reacts better with the flour. Cold applesauce can make the batter separate or leave pockets of uncooked dough. Trust me, your cake will be lighter if you do this.

Frequently asked questions
Can I use overripe bananas for this microwave banana cake?
Overripe bananas with brown spots actually make this cake even sweeter and more flavorful. The extra sugar from the ripe fruit caramelizes slightly in the microwave, adding depth. Just make sure they're not moldy—remove any black spots before mashing. For maximum flavor, use bananas with mostly brown peels.
What if I don't have applesauce? Can I substitute something else?
Yes! Try these egg substitutes in equal amounts: 0.5 cup plain yogurt, 0.5 cup pumpkin puree, or 0.5 cup mashed sweet potato. For a vegan option, use 0.5 cup flaxseed meal + 0.35 cup water (mix and let sit for 5 minutes to thicken). Each adds moisture differently, so check your cake's doneness closely.
Why does my microwave banana cake turn out gummy instead of moist?
Gummy texture usually means overcooking or underbaking. Try these fixes: First, reduce microwave time by 15-30 seconds total. Second, check your bananas—if they're not ripe enough, the cake won't be sweet enough to balance moisture. Finally, make sure your microwave-safe dish isn't too large for your serving size. A standard coffee mug works perfectly for single servings.
Can I make this recipe without yogurt for a vegan version?
Replace the 0.5 cup yogurt total with either 0.5 cup coconut milk or 0.5 cup almond milk + 1 tbsp ground flaxseed. The flaxseed adds binding power similar to eggs. For best texture, also increase the applesauce by 2 tbsp to compensate for the missing fat content in dairy-free yogurt alternatives.
How do I adjust the recipe for a larger cake?
For a standard 9x9-inch dish, double all ingredients except the baking powder (use 1.5 tsp). Microwave in 2-minute intervals**, checking after each burst. The larger volume needs more time to cook evenly. Pro tip: Grease your dish well and cover it loosely with a microwave-safe lid or damp paper towel to help the cake rise properly.
