Ingredients for banana cake tray bake
Pantry staples plus a few ripe bananas—this one-pan wonder comes together fast.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 medium | Mashed, about 1.5 cups total |
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Vegetable Oil 🫒 | ¾ cup | Light or canola oil |
| Large Eggs 🥚 | 2 whole | Room temperature for mixing |
| Baking Soda 🧪 | 1 tsp | Pure baking soda |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌸 | 1 tsp | Pure vanilla extract |
| Milk 🥛 | ½ cup | Any kind, room temp |
| Unsalted Butter 🧈 | ½ cup | Melted, full-fat preferred |
| Chopped Walnuts 🌰 | ½ cup | Optional for crunch |
| Powdered Sugar 🍚 | ¼ cup | For dusting (optional) |
Bananas are the star here. Grab ones with spots and softness—they're sweeter and mash easier. Trader Joe's or any grocery store has them year-round, but local farmers markets have the juiciest in season. I always buy extra because they're perfect for smoothies too. The walnuts? Costco or bulk bins save money, but any store's pre-chopped works. Toast them 5 minutes in a dry pan before adding—they get crispier and richer that way.
No vanilla extract? Almond extract at half the amount works in a pinch. Out of baking soda? Baking powder at 1.5 tsp can substitute, but the texture might be slightly different. The milk can be any kind—dairy, almond, or oat milk all work. For the sugar, light brown sugar adds moisture if you want to swap, but white keeps it classic. And if you're feeling fancy, a sprinkle of cinnamon sugar on top before baking gives that bakery look.
This cake keeps beautifully—3-4 days in an airtight container at room temp or 1 week in the fridge. The bananas caramelize more overnight, so leftovers taste even better. For extra indulgence, freeze portions wrapped in plastic for up to 3 months. I like to slice it warm and serve with vanilla ice cream—trust me, the contrast is next level.
Why You'll Love This Recipe
- Here’s what sold me: this tray bake works for everything. Slice it warm for a quick breakfast with a dollop of yogurt, or pack it in lunchboxes for school. Even my picky husband grabs a piece after work—no judgment, just pure satisfaction. And if you’re hosting? Double the batch and call it a crowd-pleaser.
- I’ll be real: most cakes turn into sad, dry bricks by day three. Not this one. The oil keeps it moist, and the bananas add natural sweetness that doesn’t turn stale. I’ve reheated slices in the toaster for weeks—still tender, still delicious. Plus, it’s cheap to make; you’re basically using up overripe fruit instead of tossing it. Win-win.
Step-by-step instructions for banana cake tray bake
Here's how to create a showstopping banana cake with caramelized layers—no fancy equipment needed.
👨🍳 Step 1: Prep the Bananas and Mix Wet Ingredients
Start by mashing the 3 medium ripe bananas until smooth—no lumps! I like to use a fork for this step, but a potato masher works too. The bananas should be completely broken down, almost like a thick puree. This ensures even distribution throughout the batter.
In a large mixing bowl, combine the mashed bananas with the 1.5 cups granulated sugar, 0.75 cup vegetable oil, and 0.5 cup milk. Whisk everything together until fully incorporated. The mixture will look like a thick, slightly sticky batter. This is your base—don't worry if it looks a bit too thin yet, the dry ingredients will thicken it up.
👨🍳 Step 2: Add Eggs and Aromatics
Crack the 2 whole large eggs directly into the bowl and whisk vigorously for about 30 seconds until they're fully combined. The eggs help bind everything together and add moisture to the cake. Add the 1 tsp vanilla extract and mix for another 10 seconds—this step is quick, but essential for that warm vanilla flavor.
In a separate small bowl, whisk together the 2 cups all-purpose flour, 1 tsp baking soda, 2 tsp ground cinnamon, and 0.5 tsp salt. Sift the dry ingredients right into the bowl if you have a sifter—this prevents lumps and ensures a light, airy texture. Gently fold the dry ingredients into the wet mixture using a spatula, mixing just until combined. Overmixing here can make the cake dense, so stop as soon as you see no more flour streaks.
🍳 Step 3: Fold in Butter and Walnuts
Melt the 0.5 cup unsalted butter in the microwave for 20-30 seconds or until completely liquid. Let it cool slightly, then stir it into the batter until fully incorporated. The butter adds richness and helps keep the cake moist. If you're using the 0.5 cup chopped walnuts, fold them in now—they'll add a nice crunchy texture that contrasts perfectly with the soft cake.
Real talk: the batter will look thick, but trust me—this is exactly how it should be. It's important not to add extra liquid here, as that can make the cake too moist and gummy. The butter and bananas provide enough moisture on their own.
🔥 Step 4: Assemble the Tray Bake Layers
Preheat your oven to 350°F and grease a 9x13-inch baking dish with butter or line it with parchment paper for easy removal. Pour about half of the batter into the prepared dish and spread it evenly with a spatula. Then, add half of the remaining batter in dollops on top, leaving some space between them. This creates those beautiful caramelized banana layers we're after.
Finally, pour the remaining batter over the dollops, spreading it gently to cover. The layers will blend together as it bakes, creating pockets of caramelized banana goodness. Don't worry about making it perfect—this is supposed to be rustic and delicious!
⏰ Step 5: Bake to Golden Perfection
Bake the cake for 35-40 minutes until the edges are golden brown and a toothpick inserted in the center comes out clean. The top should look slightly cracked, which is totally normal and indicates it's done. If you're unsure, check at the 30-minute mark—ovens vary, and you don't want to overbake it.
Let the cake cool in the pan for 10 minutes before transferring it to a wire rack. While it's cooling, dust the top with 0.25 cup powdered sugar for a sweet, snowy finish. Serve warm for the best texture—each slice will be moist, flavorful, and just slightly gooey in the middle. Perfect for sharing with a crowd!
Pro Tips For Making Banana Cake Tray Bake
- MASH THE BANANAS WELL: Grab a fork and really break up those bananas—no blender needed. I learned this the hard way when I skipped it once, and the cake turned out dense with pockets of unmashed fruit. The goal is a smooth, pulpy texture that mixes evenly with the wet ingredients.
- USE LESS SUGAR THAN YOU THINK: The bananas are already sweet, so cut the granulated sugar by 25% unless you’re going for a dessert-like cake. My grandmother swore by this, and she was right: the cake stays moist longer without tasting flat. Trust the fruit’s natural sweetness.
- DON’T OVERMIX THE BATTER: Once you fold in the flour, stop mixing after 10 strokes—any more and you’ll toughen the cake. I used to overdo it, and the texture ended up more like a dense muffin. A quick scrape of the spatula is all you need.
- BAKE UNTIL THE CENTER SPRINGS BACK: The toothpick test fails here—banana cakes set differently. Press the center gently with a finger; if it springs back slowly, it’s done. I skipped this once and ended up with a gummy mess. Patience pays off for a proper crumb.
Best sauces and condiments for these flavors
Caramelized Banana Glaze
For a showstopping finish, drizzle warm cake slices with a simple caramelized banana glaze. Simmer ½ cup mashed bananas, 2 tbsp brown sugar, and 1 tsp lemon juice in a small saucepan over medium heat for 3-4 minutes until thickened. Let cool slightly before drizzling—it adds a glossy, sweet contrast that makes every bite feel special. 🍯
Whipped Cream Cheese Frosting
Elevate your tray bake with a light cream cheese frosting that balances the cake's richness. Beat 4 oz cream cheese, 2 tbsp softened butter, and 1 cup powdered sugar until smooth, then fold in 1 tsp vanilla extract. Spread a thin layer between cake layers or on top for a tangy-sweet twist. Use a piping bag for decorative swirls if you're feeling fancy.
Chocolate Ganache Drizzle
Add depth with a dark chocolate ganache—melt ½ cup dark chocolate chips and ¼ cup heavy cream together in a microwave-safe bowl in 30-second intervals, stirring between each. Let cool slightly, then drizzle over slices. The bitterness cuts through the banana's sweetness beautifully. For extra flair, sprinkle with crushed hazelnuts or sea salt flakes.
Spiced Maple Syrup
Warm ¼ cup pure maple syrup with ½ tsp cinnamon and a pinch of ground nutmeg in a small saucepan over low heat for 2 minutes. Brush lightly over cake slices or drizzle alongside whipped cream. The warm spices complement the banana's natural sweetness while adding a cozy autumnal note. Perfect for fall gatherings!
Vanilla Bean Ice Cream Pairing
Serve your banana cake with vanilla bean ice cream for a classic dessert combo. Look for brands like Ben & Jerry's or Häagen-Dazs for a creamy, rich texture. For homemade, blend 2 cups heavy cream, 1 cup whole milk, ¾ cup sugar, and 1 vanilla bean (scraped) until smooth. Chill for 4+ hours before serving. The cold ice cream contrasts perfectly with the warm cake. 🍦
Cinnamon Sugar Crumble Topping
For a textural crunch, mix ¼ cup granulated sugar with 1 tbsp ground cinnamon and sprinkle over the cake before baking. The sugar caramelizes into a sweet, crisp topping that adds a bakery-style finish. You can also make a quick streusel by adding 2 tbsp cold butter and pressing it into the batter before baking for an extra layer of flavor. 🌟

Frequently asked questions
Can I make this banana cake in a different-sized baking dish?
Yes! For a 9x9-inch dish, reduce the recipe by about 30% (use 1.5 cups batter total). For a 9x13-inch dish, the recipe works perfectly. If using an 8x8-inch dish, reduce by 40%. Always adjust baking time—check for doneness at 25-30 minutes in smaller pans.
Why does my banana cake turn out dense instead of moist?
Overmixing the batter or adding extra liquid (like more milk) are common culprits. Use a spatula to fold dry ingredients gently, and never exceed the 2 cups flour measurement. Also, ensure bananas are fully ripe (black spots!) and mashed smooth—underripe bananas release less moisture.
How do I store leftovers to keep them moist?
Wrap tightly in plastic wrap or store in an airtight container with a paper towel underneath to absorb excess moisture. Reheat slices in a 350°F oven for 5-10 minutes or microwave for 15-20 seconds to restore freshness. The cake keeps well for 4 days at room temperature or 1 week refrigerated.
Can I substitute oil with butter in this recipe?
Yes, but melt ½ cup butter first and reduce milk to ¼ cup to maintain moisture balance. Butter adds richer flavor but makes the cake slightly denser. For a lighter texture, stick with oil—it keeps the cake tender while the butter version becomes more decadent.
What's the best way to serve this cake warm?
Slice warm cake (10-15 minutes out of the oven) and serve with:
- Vanilla ice cream (classic contrast)
- Whipped cream + caramelized banana glaze
- A dollop of cream cheese frosting for tangy balance Pro tip: Dust with powdered sugar right before serving for a bakery-style finish.
