Ingredients for banana carrot walnut cake
These 13 ingredients come together for a cake that’s moist, nutty, and always a crowd-pleaser.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 2 cups | Mashed, about 3 medium bananas |
| Carrots 🥕 | 2 cups | Grated, finely for even texture |
| All-Purpose Flour 🌾 | 2 ½ cups | Spooning, not scooping |
| Granulated Sugar 🍚 | 1 ½ cups | Light brown sugar for depth |
| Walnuts 🥜 | 1 ½ cups | Toasted, roughly chopped |
| Vegetable Oil 🫒 | ½ cup | Light or canola preferred |
| Pure Vanilla Extract 🌸 | 1 tbsp | High-quality for flavor |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated nutmeg |
| Baking Soda 🧂 | 1 tsp | For lift and moisture |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Large Eggs 🥚 | 2 whole | Room temperature for best mixing |
| Plain Greek Yogurt 🥛 | ½ cup | Full-fat for moisture |
The walnuts are the star here—toast them first in a dry pan until fragrant (about 5 minutes), then chop roughly. Trader Joe’s has the best-priced walnuts in bulk, but any grocery store’s nut section works. For bananas, ripe is key—black spots mean more natural sweetness. I always grab a few extra to mash into the batter, ensuring that tender crumb. Carrots should be freshly grated (the boxed kind gets watery)—a box grater works best, and take your time to get them fine.
No Greek yogurt? Substitute with sour cream or even applesauce—just reduce the oil by 1 tbsp. Walnuts too pricey? Pecans or almonds work too, though walnuts’ earthy flavor is ideal. Short on cinnamon? Cardamom at half the amount adds a unique twist. The grated carrots can be swapped for zucchini or sweet potato if needed, but the texture changes slightly. For a lighter cake, reduce sugar by 2 tbsp—the bananas and carrots add natural sweetness.
This cake keeps beautifully—3-4 days in an airtight container at room temp, or up to 1 week in the fridge. For longer storage, wrap tightly and freeze for up to 3 months. I always bake two batches—one for right away, one to freeze for lazy days. Toasted walnuts lose their crunch when stored, so toast fresh before serving if keeping the cake longer than a day.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this recipe when my mixer’s broken (again). Mash those bananas and shred carrots by hand—no fancy tools, just elbow grease. The walnuts add texture without extra work, and the batter’s so forgiving you’ll forget you’re baking.

- Breakfast or Snack: Honestly, I’ve eaten this cold for breakfast with a drizzle of honey, or warm with a scoop of vanilla ice cream. The texture holds up either way—no soggy middle, no dry crumbs. Pack a slice in your lunchbox, or bring it to a picnic where it’ll disappear faster than you can say "second helping."

Step-by-step instructions for banana carrot walnut cake
This cake delivers perfect moisture and nutty crunch every time—follow my foolproof method.
Prep the Wet Ingredients for Maximum Moisture
Start by mashing the 2 cups ripe bananas until completely smooth—no lumps allowed. I like to use a fork first, then give it a quick pulse in a food processor if needed. The riper the bananas, the sweeter and more tender your cake will be. In a separate bowl, whisk together the 0.5 cup plain Greek yogurt, 0.5 cup vegetable oil, and 1 tbsp pure vanilla extract. This yogurt-oil blend creates that signature moist texture we're after.
Let the mashed bananas sit at room temperature for 5 minutes while you prep the rest. This small step helps prevent the cake from becoming too dense when mixed with the dry ingredients. The yogurt adds protein for structure while keeping things light, and the oil ensures that moist crumb we all love.
Combine Dry Ingredients with Spices for Even Distribution
In a large mixing bowl, sift together the 2.5 cups all-purpose flour, 1.5 cups granulated sugar, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, 1 tsp baking soda, and 0.5 tsp salt. I always sift the flour first—this prevents lumps and ensures even distribution of those warm spices throughout the batter. Give it a quick stir with a whisk to break up any remaining clumps.
Toast the 1.5 cups walnuts in a dry skillet over medium heat for 3-4 minutes until fragrant and lightly golden. Watch them closely—they burn fast! Let them cool completely before chopping roughly. The toasted walnuts add that incredible crunch and nutty depth that makes this cake special. Set them aside for later.
Mix Wet and Dry Ingredients Gently for a Light Batter
Pour the banana mixture into the dry ingredients and stir gently with a spatula until just combined. I mean it—don't overmix! You should still see some flour streaks. Add the 2 whole large eggs one at a time, mixing just until incorporated after each addition. The goal is to create a thick but pourable batter that holds its shape when poured.
Fold in the toasted walnuts using a rubber spatula, being careful not to break them up too much. You want those chunks distributed evenly throughout. The batter will be thick, almost like cookie dough, which is perfect for this dense yet moist cake. If it seems too thick, you can add 1-2 tablespoons of milk (though our ingredients don't call for it), but trust the recipe—this is exactly how it should be.
Bake Until Golden and Springy for Perfect Texture
Preheat your oven to 350°F and grease a 9-inch round cake pan or line it with parchment paper. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 45-50 minutes until a toothpick inserted in the center comes out clean and the top is golden brown. I know it seems like a long time, but patience here prevents a dry cake.
Here's the thing—this cake needs that full baking time to develop its signature moist texture. The carrots and bananas add natural moisture, but the baking soda needs time to work its magic. When you pull it out, let it cool in the pan for 10 minutes before transferring to a wire rack. This resting period helps it set properly, preventing it from falling apart when you slice it.
Serve Warm with Creamy Frosting or Fresh Fruit
While the cake cools, make your favorite cream cheese frosting or simply dust it with powdered sugar for a classic finish. I love serving this cake warm with a dollop of whipped cream or a scoop of vanilla ice cream. The contrast of warm cake with cool toppings is pure magic. Each slice should be moist, tender, and packed with those little walnut surprises throughout.
Cut into 12 equal slices for perfect portions. The cake will keep well at room temperature for 2-3 days in an airtight container, though I promise you won't have any leftovers. The combination of sweet bananas, earthy carrots, and crunchy walnuts creates a flavor profile that's hard to resist. Enjoy it as-is or with a cup of coffee for the ultimate comfort food experience!
Pro Tips For Making Banana Carrot Walnut Cake
- GRATE THOSE CARROTS SMALL: I learned this the hard way—big chunks of carrot turn into a weird, chewy texture in the cake. Use the fine side of a box grater and stop when you hit about 1½ cups; any more and the cake gets dense. (Yes, even if you’re impatient like me.)
- MASH BANANAS UNTIL Smooth: Lumpy banana puree makes for a cake with pockets of undercooked fruit. Mash them with a fork first, then press through a fine-mesh sieve or blend briefly with the sugar—this keeps the texture light and prevents sinking in the middle.
- TOAST THE WALNUTS FIRST: Raw walnuts taste bitter and release oil that makes the cake greasy. Toast them in a dry pan over medium heat for 5–7 minutes until fragrant and lightly golden. Let them cool before chopping—this also makes them easier to handle and adds depth of flavor.
- TEST DONENESS WITH A SKEWER: The cake might look set but still be undercooked inside. Insert a thin skewer or toothpick into the center—it should come out with a few moist crumbs, not wet batter. If unsure, check at 3–5 minute intervals; overbaking turns this moist cake dry.
Serving suggestions for this banana carrot walnut cake
Classic Cream Cheese Frosting
My go-to frosting for this cake is a simple cream cheese glaze that balances the cake’s natural sweetness. Mix 8 oz cream cheese (softened), ½ cup unsalted butter, 2 cups powdered sugar, and 1 tsp vanilla extract until smooth. Spread a thin layer over the cooled cake—just enough to enhance flavor without overwhelming it. For extra flair, sprinkle with toasted walnut pieces or a pinch of cinnamon. 🍯
Fresh Fruit Toppings
Brighten each slice with fresh fruit that complements the cake’s warm spices. I love thinly sliced peaches or strawberries arranged on top—their natural juices create a beautiful contrast. For a tropical twist, use mango chunks or kiwi slices. Serve at room temperature so the fruit softens slightly, releasing its juices onto the cake. 🍓
Whipped Cream Pairing
A dollop of homemade whipped cream (or store-bought) adds a light, airy finish that cuts through the cake’s density. Whip 1 cup heavy cream with 1 tbsp powdered sugar and a pinch of salt until soft peaks form. Top each slice generously and garnish with a sprinkle of crushed walnuts or a drizzle of honey. This pairing feels indulgent without being heavy. ✨
Caramel Drizzle
For a decadent touch, drizzle warm salted caramel sauce over the cake before serving. Heat ½ cup caramel sauce (homemade or store-bought) until pourable, then drizzle in zigzags. The salty-sweet contrast elevates the cake’s natural flavors. I use Trader Joe’s salted caramel sauce for convenience—it’s rich and perfectly balanced. 🥄
Coffee or Tea Pairings
Serve this cake with a hot cup of coffee or Earl Grey tea to highlight its spiced notes. The caffeine enhances the cake’s cinnamon and nutmeg flavors, while the tea’s bergamot adds a citrusy brightness. For a non-caffeinated option, try chamomile tea—its floral notes pair beautifully with the walnuts. ☕
Make-Ahead Serving Tips
If serving later, store the cake in an airtight container at room temperature for up to 3 days. Reheat slices in the microwave for 10-15 seconds** to restore warmth. For parties, assemble the cake the day before and refrigerate—bring it to room temperature before serving. The flavors deepen overnight, making it even more delicious. 💫

Frequently asked questions
Can I substitute walnuts with another nut in this cake?
If walnuts aren't available, try pecans or almonds for a similar texture. Pecans add a slightly sweeter flavor, while almonds offer a milder taste. Toast them first for maximum flavor—just 3-4 minutes in a dry pan until fragrant.
What makes this cake extra moist compared to regular banana cakes?
The combination of mashed ripe bananas, Greek yogurt, and vegetable oil creates that signature moisture. The yogurt adds protein for structure while keeping the crumb tender, and the oil ensures a rich, velvety texture. Plus, the carrots contribute natural sweetness without needing extra liquid.
How do I know when the cake is fully baked?
Your cake is done when a toothpick inserted in the center comes out clean and the edges pull away slightly from the pan. The top should also be golden brown. Baking for the full 45-50 minutes ensures the baking soda works its magic for that perfect texture.
Can I make this cake gluten-free?
Yes! Replace the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill). You may need to add ½ tsp xanthan gum to help bind the cake. Also, use gluten-free oats if toasting for extra crunch instead of walnuts. Keep in mind the texture will be slightly denser.
Why did my cake turn out dry?
Dryness usually happens when overbaked or under-mixed. Check your oven temperature with an oven thermometer—it might be running hot. Also, ensure you're not overmixing the batter (just combine until flour disappears). For extra moisture, try adding 1-2 tbsp applesauce to the batter next time.
