Desserts
Ainsley Harriott's banana bread recipe delivers the kind of moist, walnut-studded perfection that turns overripe bananas into a dessert-worthy masterpiece. The secret lies in blending ripe bananas with vanilla and brown sugar, creating a dense, flavorful batter that stays tender for days.
I've perfected this version to capture Harriott's signature texture—no dry crumbs here.
What sets this apart is the walnut studding and subtle vanilla infusion that elevate it beyond basic banana bread. The recipe uses a one-bowl method for simplicity, with just 10 minutes of prep before baking at 350°F for 50-60 minutes.
The internal temperature test (205°F) ensures perfect doneness every time, while optional cream cheese glaze adds that restaurant-quality finish.
By the time it emerges from the oven, you'll have a loaf with a golden crust, tender crumb, and pockets of caramelized banana flavor. The walnuts add satisfying crunch, while the vanilla deepens the natural sweetness of the fruit.
This isn't just banana bread—it's a dessert that feels like a hug in loaf form.
Perfect for breakfast, afternoon treats, or gifting, this recipe scales beautifully. The moist texture makes it ideal for slicing thick or serving with tea. Let's make it—your taste buds will thank you.
Ingredients for ainsley harriott banana bread
Perfectly ripe bananas, walnuts, and vanilla create Ainsley Harriott's signature moist banana bread masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 medium | Overripe with brown spots |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Dark Brown Sugar 🍚 | 1 ½ cups | Packed firmly |
| Vanilla Extract 🍯 | 2 tsp | Pure Madagascar preferred |
| Unsalted Butter 🧈 | 1 cup | Melted, full-fat |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Walnuts 🥜 | 1 ½ cups | Chopped, toasted lightly |
| Baking Soda 🧂 | 1 tsp | Freshly opened |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Milk 🥛 | ½ cup | Whole milk preferred |
| Cream Cheese Glaze 🧀 | 4 oz | Optional, softened |
| Powdered Sugar 🍚 | ½ cup | For glaze only |
The bananas are non-negotiable—look for those with black speckles and soft spots; they're sweeter and more flavorful. Trader Joe's and Whole Foods often have perfect ones, but any grocery store will work if you pick carefully. Walnuts should be fresh—check the sell-by date, and toast them lightly before chopping to bring out their flavor. The vanilla extract matters too; Madagascar bourbon is ideal, but pure vanilla will do. For the butter, Land O'Lakes or Plugrá are reliable choices, but any good-quality unsalted butter works.
No ripe bananas? Use 1 cup banana puree from frozen overripe bananas—blend them with a splash of milk to get the right consistency. Running short on walnuts? Pecans or almonds work in a pinch, though they change the texture slightly. The milk can be swapped for almond or oat milk, but whole milk keeps the bread extra moist. For the glaze, cream cheese must be softened—microwave it for 20 seconds if it's too firm. And if you're out of powdered sugar, blend regular sugar in a food processor for a quick fix.
This loaf stays fresh for 3-4 days at room temperature, wrapped tightly in foil. For longer storage, slice and freeze portions for up to 3 months. The glaze keeps for 1 week in the fridge, so make it fresh when ready to serve. Reheat slices in the oven for 10 seconds to restore softness—no microwave needed. The walnuts will keep their crunch if you store the bread in an airtight container with a slice of bread in the bag to absorb moisture.

Step-by-step instructions for Ainsley Harriott's banana bread
Here's how to bake this legendary walnut-studded loaf with perfect moisture and texture.
Prepare the Banana and Butter Mixture
Preheat your oven to 350°F and grease a 9x5-inch loaf pan with butter or line it with parchment paper. In a large mixing bowl, mash the 3 medium ripe bananas with a fork until completely smooth—no lumps should remain. This ensures an even texture throughout the bread.
Add the 1 cup melted unsalted butter and 1.5 cups packed dark brown sugar to the banana mixture. Stir vigorously until fully combined. The butter should be fully incorporated, creating a thick, syrupy base. This step is crucial for developing that signature moistness Ainsley Harriott is known for.
Combine Wet and Dry Ingredients
In a separate bowl, whisk together the 2.5 cups sifted all-purpose flour, 1 tsp baking soda, and 0.5 tsp salt. Sifting the flour ensures a light, airy texture that prevents dense, heavy bread. Gradually add this dry mixture to the banana-butter mixture while stirring gently with a wooden spoon.
Add the 2 whole room-temperature eggs and 0.5 cup milk, mixing just until combined. Avoid overmixing—the batter should be thick but not stiff. The eggs provide structure while maintaining moisture, and the milk creates a tender crumb. Fold in the 1.5 cups chopped toasted walnuts last, ensuring even distribution throughout the batter.
Bake to Golden Perfection
Pour the batter into the prepared loaf pan and smooth the top with a spatula. Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean. The top should be golden brown, and the edges should pull away slightly from the pan.
I always tap the loaf gently on the pan's side about 10 minutes before the toothpick test—this helps determine doneness without overbaking. The walnuts should be toasted but not burnt, and the bread should spring back slightly when pressed. Let it cool in the pan for 15 minutes before transferring to a wire rack.
Add the Cream Cheese Glaze (Optional)
While the bread cools, prepare the optional cream cheese glaze by beating the 4 oz softened cream cheese with an electric mixer until smooth. Gradually add the 0.5 cup powdered sugar and 2 tsp vanilla extract, mixing until light and fluffy. This glaze adds a luxurious finish that balances the bread's richness.
Once the bread has cooled completely, drizzle the glaze evenly over the top. Use a fork to create decorative swirls if desired. The glaze should set within 30 minutes, creating a glossy, sweet finish. Serve slices at room temperature for the best texture and flavor.
Pro Tips For Making Ainsley Harriott Banana Bread
- Mash Bananas Thoroughly: I learned this the hard way—lumpy banana purée makes for a dense, uneven crumb. Use a fork first to break up the fruit, then press through a sieve or fine-mesh strainer to remove skins and fiber. The smoother the purée, the lighter the texture.
- Use Warm Butter: Cold butter creates pockets of dryness in the crumb. Microwave the unsalted butter for 10–15 seconds until soft but not melted, then whip it with the brown sugar until fluffy. This ensures even distribution and a tender bite.
- Check Doneness Early: This bread’s exterior can look done before the center is set. After 50 minutes, insert a skewer—if it comes out clean but the edges pull away slightly, it’s ready. Overbaking dries it out, and no one wants a sad, crumbly loaf.
- Add a Pinch of Salt: The recipe calls for brown sugar, which already has some salt, but the butter is unsalted. Taste the batter before baking—if it’s bland, add a ¼ teaspoon of fine salt. It balances the sweetness and rounds out the flavors.
Make-ahead tips for this dish
Banana Prep Ahead
Mash your bananas up to 3 days in advance and store them in an airtight container in the fridge. The flavors intensify as they sit, becoming sweeter and more aromatic.
When ready to bake, let them sit at room temperature for 15 minutes before mixing—they'll be easier to incorporate into the batter. 🍌
Batter Storage
Mix the entire batter (without walnuts) up to 24 hours ahead and refrigerate in an airtight container. When you're ready to bake, fold in the walnuts and proceed with the recipe.
This method helps develop deeper flavors overnight. For best results, let the batter sit at room temperature for 30 minutes before baking to even out the consistency.
Walnut Prep
Toast and chop your walnuts a week ahead and store them in the freezer in a resealable bag. This preserves their freshness and crunch.
When you're ready to bake, simply remove them from the freezer and let them warm to room temperature for 10 minutes before folding into the batter. Pre-toasted walnuts add an extra layer of flavor that's hard to beat. 🥜
Glaze Pre-Make
Prepare the cream cheese glaze 1 day ahead and store it in the fridge in an airtight container. The flavors meld beautifully, and it's ready to drizzle whenever you're ready to serve.
Give it a quick whisk before using to restore its smooth texture. This is especially helpful if you're planning to make the bread ahead of time and want that restaurant-quality finish.
Fully Baked Storage
This banana bread stays fresh for 3-4 days at room temperature, wrapped tightly in plastic wrap or aluminum foil. For longer storage, slice the loaf and freeze individual portions for up to 3 months.
To serve, simply thaw at room temperature for 1-2 hours—no reheating needed. The walnuts stay crisp, and the bread remains moist and delicious. ❄️
Freezing Tips
If you're making this for a crowd, bake the loaf, let it cool completely, and then slice it into 1-inch thick portions. Place each slice in a freezer bag with parchment paper between them to prevent sticking.
When ready to enjoy, microwave individual slices for 15-20 seconds or reheat in the oven at 300°F for 5 minutes to restore that fresh-baked texture. Perfect for meal prep! 💡

Frequently asked questions
Why does Ainsley Harriott's recipe use dark brown sugar instead of white?
Dark brown sugar adds richer caramel notes and deeper moisture to the bread. The molasses content creates a chewier texture and balances the natural sweetness of overripe bananas. It also enhances the walnuts' flavor, making every bite more complex than traditional recipes with white sugar.
Can I substitute walnuts with another nut?
Yes! Pecans or almonds work well, though they change the texture slightly. Pecans add a buttery sweetness, while almonds keep the crunch but with a milder flavor. For a nut-free version, try chopped dried apricots or chocolate chips—both pair beautifully with banana bread.
How do I know when the banana bread is fully baked?
Use the toothpick test—insert it into the center and check for clean results. The edges should also pull away from the pan slightly. A gentle tap on the loaf should sound hollow. The internal temperature should reach 205°F for perfect doneness.
Will this recipe work with frozen bananas?
Use 1 cup banana puree made from frozen overripe bananas blended with 1 tablespoon milk. The texture will be slightly thicker, but the flavor remains delicious. For best results, thaw the frozen bananas overnight in the fridge before blending.
Can I make this banana bread in a different pan size?
For a 9x5-inch pan, use the full recipe. For an 8x4-inch pan, reduce baking time by 10-15 minutes. If using a 9x2-inch round pan, bake for 40-45 minutes—the shape affects heat distribution. Always adjust oven racks to the middle position for even baking.
