Ingredients for banana cake no bake
Twelve easy ingredients transform ripe bananas into fudgy layers and velvety frosting—no oven needed.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 medium | Overripe, mashed completely |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for smooth texture |
| Granulated Sugar 🍚 | 1 cup | White or brown preferred |
| Vegetable Oil 🫒 | ½ cup | Neutral flavor, not olive |
| Vanilla Extract 🌿 | 1 tbsp | Pure, not imitation |
| Baking Powder 🍞 | 1 ½ tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Almond Milk 🥛 | ½ cup | Unsweetened, chilled |
| Cream Cheese 🧀 | 8 oz | Room temperature, full-fat |
| Powdered Sugar 🍚 | 2 cups | Sifted for smooth frosting |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Chopped Walnuts 🌰 | ¼ cup | Optional, for garnish |
Bananas are the star here—grab the spottiest ones from your fruit bowl. Trader Joe's or any grocery store usually has them at the back of the produce section. The cream cheese should be full-fat for that rich frosting—Philadelphia brand works perfectly. Flour matters too: King Arthur or any high-quality brand keeps this cake sturdy. For the frosting, powdered sugar needs to be sifted to avoid lumps, so grab a fine-mesh strainer if you don't have a sifter. Walnuts are optional but add a nice crunch—Costco sells them in bulk for great prices.
No almond milk? Oat milk or coconut milk works just as well. Running out of powdered sugar? Granulated sugar blended into a fine powder in a food processor does the trick. The frosting can be made dairy-free by using vegan cream cheese—Kite Hill is a solid choice. For extra tang, add an extra teaspoon of lemon juice. If you're not a fan of walnuts, chopped pecans or toasted coconut make great alternatives. The baking powder is essential here—don't skip it, even though this is no-bake.
This cake keeps beautifully in the fridge for 5 days wrapped tightly in plastic. The frosting can be made a day ahead and stored separately. For best texture, let the cake sit at room temperature for 10 minutes before slicing. Portion into individual servings for parties—it's always a crowd-pleaser. Freezes well too, though the texture gets slightly denser after thawing. Serve with a sprinkle of powdered sugar or a drizzle of melted chocolate for extra flair.

Step-by-step instructions for banana cake no-bake recipe
Here's how to make this rich, fudgy banana cake with silky cream cheese frosting—no oven required!
👨🍳 Step 1: Mix the Cake Batter Like a Pro
In a large mixing bowl, mash the 3 medium ripe bananas completely with a fork until smooth—no lumps allowed. This is your secret weapon for moisture and natural sweetness. Add the 1 cup granulated sugar, 0.5 cup vegetable oil, and 1 tbsp vanilla extract, then mix until fully combined.
Sift in the 1.5 cups all-purpose flour, 1.5 tsp baking powder, and 0.5 tsp salt all at once. Gently fold with a spatula until just incorporated—overmixing makes it tough. Pour in the 0.5 cup chilled almond milk and stir until the batter is smooth and thick, like pudding. Here's the thing—this batter should be dense, not runny. If it's too thick, add 1-2 tablespoons more almond milk to help it spread evenly in the pan.
🥘 Step 2: Layer and Chill for Perfect Texture
Grease a 9x13-inch baking dish with vegetable oil or line it with parchment paper for easy removal. Pour half the batter into the pan and spread it evenly with a spatula. Sprinkle ⅓ of the chopped walnuts (if using) over the first layer for crunch. Repeat with the remaining batter and walnuts.
Cover the dish tightly with plastic wrap and refrigerate for at least 4 hours—overnight is even better. This chilling time is non-negotiable; it lets the flavors meld and the texture set properly. You'll know it's ready when a toothpick inserted comes out clean (no wet batter). Pro tip: Tap the pan gently—if it feels firm, it's ready!
🍳 Step 3: Whip the Cream Cheese Frosting
While the cake chills, beat the 8 oz room-temperature cream cheese in a large bowl until completely smooth—no lumps, or the frosting will be grainy. Gradually add the 2 cups powdered sugar and mix on low speed until combined. Pour in the 1 tbsp freshly squeezed lemon juice and the 1 tbsp vanilla extract, then beat on medium-high for 2-3 minutes until light and fluffy.
This is where the magic happens: the lemon juice brightens the flavor while the vanilla deepens it. If the frosting looks too thick, add 1-2 tablespoons almond milk to reach a smooth, spreadable consistency. Here's the moment that matters: let it sit at room temperature for 10 minutes before spreading—this prevents it from sliding off the cake later.
🎂 Step 4: Assemble and Garnish Like a Baker
Remove the cake from the fridge and spread the frosting evenly over the top, using a spatula to create clean edges. For extra decadence, add a thin layer of frosting on top and swirl it with a knife for a marbled effect. Sprinkle the remaining chopped walnuts over the frosting while it's still soft—they'll stick better and add that perfect crunch.
Let the cake sit at room temperature for 30 minutes before slicing. This resting time lets the frosting set slightly and the flavors meld. Cut into 12 equal squares and serve immediately—this cake is best enjoyed fresh. Store leftovers in the fridge for up to 5 days, but honestly? It won't last that long!
Pro Tips For Making Banana Cake No Bake
- MASH THE BANANAS WELL: Grab a fork and get in there—no half-measures. Overripe bananas break down into a thick, smooth purée, not a chunky mess. I learned this the hard way when my first batch had visible specks that made the cake taste unevenly sweet.
- WEIGH THE FLOUR (OR SIFT IT): Spooning flour straight from the bag packs in air, and that’s how you end up with a dense, brick-like cake. Use a kitchen scale for precision, or sift it into the bowl if you’re measuring by cup. Trust me, your future self will notice the difference in texture.
- LET THE BATTER REST: Mix it up, then walk away for 10 minutes. This isn’t just waiting—it’s letting the flour absorb the banana’s moisture so the cake doesn’t crumble when you slice it. I used to skip this, and the result was always disappointingly dry.
- OIL THE PAN THIN: A light coat of vegetable oil on the sides of your pan is all you need—no need to slather it. Too much oil makes the cake greasy, and you’ll end up fighting that flavor instead of enjoying the banana’s natural sweetness. Wipe any excess with a paper towel.
Perfect pairings for these flavors
Creamy Frosting Upgrades
Skip the basic frosting and try mascarpone cheese instead of cream cheese for a lighter, silkier texture. Mix 8 oz mascarpone with 1.5 cups powdered sugar and 1 tsp vanilla—it whips up ultra-smooth with a subtle tang. For extra richness, fold in 2 tbsp heavy cream to create a pipeable consistency perfect for rosettes. 💛
Fruity Toppings
Fresh berries transform this dessert into a summer showstopper. Arrange strawberries, blueberries, and raspberries in a circular pattern on top of the frosting for vibrant color. A drizzle of honey or chocolate ganache ties everything together. For a tropical twist, use mango slices or pineapple chunks—their natural sweetness complements the banana perfectly.
Chocolate Variations
Add ½ cup cocoa powder to the cake batter for a chocolate-banana fusion. Use dark chocolate (60-70%) for depth, or milk chocolate for a sweeter profile. For the frosting, swap powdered sugar for ½ cup melted chocolate chips> mixed with 1.5 cups powdered sugar—this creates a decadent ganache-like topping. A sprinkle of sea salt on top enhances the chocolate flavor.
Nutty Crunch Alternatives
Walnuts aren’t your only option! Try pecans, almonds, or hazelnuts for different textures. Toast them first in a dry pan for 3-5 minutes> until fragrant—this amplifies their natural oils. For a nut-free version, use crushed graham crackers or toasted coconut flakes instead. A pinch of cinnamon sprinkled over the frosting adds warmth that pairs beautifully with banana.
Boozy Enhancements
Infuse the frosting with 1 tbsp bourbon, rum, or orange liqueur for an adult twist. The alcohol evaporates slightly during chilling but leaves behind a subtle, sophisticated flavor. For a non-alcoholic version, use vanilla extract or almond extract for depth. A drizzle of caramel sauce over the top adds a sticky, indulgent finish that’s perfect for celebrations.

Frequently asked questions
Can I make this banana cake without nuts?
Simply omit the walnuts and use crushed graham crackers or toasted coconut flakes for texture instead. For extra flavor, sprinkle a pinch of cinnamon over the frosting. The cake will still hold together beautifully without nuts.
Why does my no-bake banana cake crumble when slicing?
This usually happens if the cake wasn't chilled long enough. The minimum 4-hour fridge time is crucial—try chilling overnight for best results. Also, ensure your batter wasn't too wet (add 1-2 extra tbsp flour if needed) and that you're using room-temperature cream cheese for the frosting.
Can I use regular milk instead of almond milk?
Yes, but the texture may be slightly denser. For best results, use unsweetened plant-based milk (like oat or soy) to maintain the cake's moisture balance. If using dairy milk, reduce the almond milk to 0.25 cup and add 0.25 cup water to keep the batter workable.
How do I make this cake vegan?
Replace the cream cheese with 8 oz vegan cream cheese (like Kite Hill) and use coconut milk instead of almond milk. For extra binding, add 1 tbsp ground flaxseed mixed with 3 tbsp water to the batter. The frosting will still be rich and creamy!
Can I make individual portions instead of a sheet cake?
Yes! Divide the batter evenly among 6-8 small ramekins (4 oz size) and layer with frosting. Chill for 3 hours before unmolding. These make perfect single servings for parties or meal prep. Garnish each with a dollop of frosting and a sprinkle of nuts for presentation.
