Ingredients for banana nut cake recipe moist
Ripe bananas, toasted walnuts, and a perfect butter-oil mix create this ultra-moist cake.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 medium | Spotty black skins preferred |
| Unsalted Butter 🧈 | 1 cup | Softened but not melted |
| Vegetable Oil 🫒 | ½ cup | For extra moisture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Packed Brown Sugar 🍚 | ½ cup | Light or dark |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for best texture |
| Walnuts 🥜 | 1 ½ cups | Toasted and chopped |
| Eggs 🥚 | 2 large | Room temperature |
| Vanilla Extract 🌿 | 2 tsp | Pure extract preferred |
| Baking Soda 🧂 | 1 tsp | Freshly opened |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Powdered Sugar 🍚 | ¼ cup | For dusting |
| Milk 🥛 | ½ cup | Whole milk preferred |
The bananas are non-negotiable here—look for those with black spots on the peel, not just yellow. Trader Joe's and Whole Foods usually have the ripest ones in the produce section. Walnuts should be toasted just until fragrant—Costco sells them pre-toasted, which saves time. For the butter, I always grab Plugrá or Land O'Lakes because they're consistently reliable. The milk? Whole milk makes it richer, but 2% works too if you're watching calories.
No ripe bananas? Use 1/4 cup banana puree instead of whole bananas, but you'll lose that signature texture. Subbing walnuts? Pecans or hazelnuts work, but toast them first. Short on butter? Applesauce at half the amount keeps it moist. The vanilla extract is where you can splurge—McCormick Pure Vanilla is my go-to, but any pure extract will do. If you're baking at high altitude, add 1/4 cup extra flour to prevent sinking.
This cake stays moist for 5 days wrapped in foil at room temperature, or 1 week in the fridge. For freezing, slice it first—3 months in a sealed container. The walnuts get crunchier over time, so I always toast a fresh batch before serving. Store the powdered sugar in an airtight container to keep it fluffy for dusting.

Step-by-step instructions for banana nut cake with perfect moisture
Here's how to bake a banana nut cake with a moist, tender crumb that stays fresh for days.
👨🍳 Step 1: Prep Ingredients for Maximum Flavor
Toast the 1.5 cups walnuts in a dry skillet over medium heat for 5-7 minutes until fragrant and golden brown. Watch them closely—they burn quickly! Transfer to a cutting board and chop them coarsely. Set aside to cool completely.
Mash the 3 medium ripe bananas with a fork in a large mixing bowl until smooth but still slightly lumpy. This texture helps incorporate air while keeping the cake moist. Add the 1 cup softened unsalted butter, 0.5 cup vegetable oil, 1.5 cups granulated sugar, and 0.5 cup packed brown sugar to the bowl. Mix until fully combined and no streaks remain.
👨🍳 Step 2: Combine Wet and Dry Ingredients Gently
In a separate bowl, whisk together the 2.5 cups all-purpose flour, 1 tsp baking soda, and 0.5 tsp salt. Sift the mixture once to aerate it—this prevents a dense crumb. Add the dry ingredients to the wet mixture in 3 equal additions, mixing just until combined after each addition. Overmixing develops gluten, which makes the cake tough.
Add the 2 large eggs one at a time, mixing until just incorporated. Stir in the 2 tsp vanilla extract and 0.5 cup milk. Fold in the toasted, chopped walnuts using a spatula—don't overmix or they'll sink to the bottom. The batter should be thick but pourable, like pancake batter.
🔥 Step 3: Bake in Two Layers for Even Cooking
Preheat your oven to 350°F and grease two 9-inch round cake pans generously with butter and flour, or use parchment liners. Divide the batter evenly between the pans. Tap each pan firmly on the counter 3 times to remove any air bubbles and ensure even rising.
Bake for 25-30 minutes until a toothpick inserted in the center comes out clean. The edges should be golden brown, but the top might still look slightly underdone. Rotate the pans halfway through baking for even heat distribution. Real talk: your oven might run hot, so start checking at the 20-minute mark—don't walk away!
⏰ Step 4: Cool and Layer for Ultimate Moisture
Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then transfer them to a wire rack to cool completely. While they cool, make a simple glaze by whisking together the 0.25 cup powdered sugar and 2 tablespoons milk until smooth.
Once completely cool, place one cake layer on a serving plate. Spread a thin layer of the glaze over the top, then place the second layer on top. Brush the remaining glaze over the entire cake. This keeps the cake moist for days—trust me, it works! For extra crunch, sprinkle with additional chopped walnuts before serving.
Pro Tips For Making Banana Nut Cake Recipe Moist
- Mash Bananas Thoroughly: I learned this the hard way—lumpy mashed bananas mean uneven moisture. Use a fork first, then a potato masher or wooden spoon to break up every last bit of fiber. No blender needed, but if you’re impatient, pulse briefly just to smooth it out. The goal is a thick, creamy purée that coats the batter evenly.
- Bake at 325°F, Not Higher: That 350°F callout in recipes is a lie for banana nut cake. High heat dries out the bananas before the cake sets. Stick to 325°F and bake until a toothpick comes out with moist crumbs—not wet batter, not dry flour. Overbaking is the fastest way to ruin a moist cake.
- Add Oil to Butter: Your recipe lists both butter and vegetable oil? Don’t skip the oil. Mix ½ cup melted butter with ¼ cup oil for a tender crumb. The oil keeps the cake from getting too dense, while the butter adds richness. (Yes, even if you’re using high-fat butter—this is non-negotiable for moisture.)
- Skip the Overmixing: I used to beat this batter until my arm gave out, thinking more mixing = better cake. Wrong. Fold in the nuts and flour just until combined—lumps are fine. Overworking the batter develops gluten, which turns your moist cake into a dry brick. Stop when the dry ingredients disappear.
Make-ahead tips for leftovers
Prep Ahead for Stress-Free Baking
Mix the batter up to 24 hours in advance and store it in an airtight container in the fridge. The flavors meld beautifully overnight, and the batter thickens just enough to prevent sinking. When ready to bake, let it sit at room temperature for 30 minutes before dividing into pans. I always do this when hosting—it saves me last-minute stress! 💪
Freeze the Batter for Later
Divide the mixed batter into two freezer-safe bags and freeze flat for up to 3 months. When you're ready to bake, thaw overnight in the fridge, then proceed as directed. This is my go-to when I know I'll have guests but don't want to bake the day of. Just
Assemble the Cake Early
Bake the layers up to 2 days ahead and store them wrapped tightly in plastic wrap at room temperature. When ready to serve, simply glaze and assemble. The glaze keeps the cake moist, and the layers stay fresh longer. I like to add a fresh sprinkle of toasted walnuts right before serving to keep that crunchy texture. ✨
Storage Secrets for Maximum Moisture
For short-term storage, keep the fully assembled cake in an airtight container at room temperature for up to 5 days. If you're storing it longer, slice it first and freeze individual portions in quart-sized freezer bags for up to 3 months. The slices reheat beautifully in the microwave for 10-15 seconds to restore that warm, moist texture.
Make-Ahead Serving Suggestions
If you're planning to serve the cake cold, chill it in the fridge for 1-2 hours before slicing. The cold temperature enhances the flavors and makes it perfect for a refreshing dessert. For a warm serving, bake fresh layers and assemble just before serving. A dusting of powdered sugar or a scoop of vanilla ice cream makes it even more special. 🍽️
Toast Nuts Fresh Before Serving
To keep the walnuts at their crispy best, toast a fresh batch right before serving. Spread them on a baking sheet and toast in a 350°F oven for 5-7 minutes until fragrant. Sprinkle them over the cake just before serving to maintain that perfect crunch. This small step makes a big difference in texture and flavor. 🥜

Frequently asked questions
Why does this banana nut cake stay moist longer than others?
The secret is the combination of ripe bananas (their natural sugars retain moisture) and the butter-oil mix, which creates a tender crumb. The powdered sugar glaze also acts as a sealant, locking in moisture for days. Plus, the 10-minute cooling in pans helps distribute heat evenly for even baking.
Can I substitute walnuts for another type of nut?
Yes! Pecans or hazelnuts work beautifully—just toast them first for maximum flavor. For a sweeter option, try candied pecans. If you prefer a crunchier texture, chop them slightly coarser. The key is toasting to enhance their natural oils, which keeps the cake moist while adding texture.
What’s the best way to tell if my bananas are ripe enough?
Look for bananas with black spots covering at least 50% of the peel—this means they’re perfectly sweet and full of natural sugars. Avoid bananas that are mostly yellow or too mushy, as they can make the cake taste overly sweet or cause it to sink. If you’re unsure, gently press the banana: it should yield slightly but not feel mushy.
Why did my cake come out dry?
Dry cake usually means overbaking or under-moisture. Double-check your baking time—25-30 minutes is ideal at 350°F. If your oven runs hot, start checking at 20 minutes. Also, ensure you used ripe bananas and didn’t skip the oil—both are critical for moisture. For extra insurance, brush the warm cake with simple syrup (equal parts sugar and water).
Can I make this cake in a bundt pan instead of round layers?
Reduce the baking time to 40-45 minutes and check for doneness with a toothpick. The batter will spread more in a bundt pan, so fill it only 2/3 full. For extra flair, sprinkle chopped walnuts on top before baking. Just remember—bundt cakes often require a slightly longer bake time due to their shape.
