Ingredients for banana cake loaf tin
These 12 simple ingredients transform into a restaurant-quality loaf cake with golden crust and soft swirls.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 medium | Mashed, about 1.5 cups |
| All-Purpose Flour 🌾 | 2 cups | Sifted, plus extra for dusting |
| Granulated Sugar 🍚 | 1 cup | Light brown sugar works too |
| Unsalted Butter 🧈 | ¾ cup | Room temperature, full-fat |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Baking Powder 🧂 | 2 tsp | Aluminum-free preferred |
| Ground Cinnamon 🌿 | 1 ½ tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ¼ tsp | Freshly grated preferred |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Vanilla Extract 🌸 | 1 tsp | Pure vanilla preferred |
| Creamy Peanut Butter 🥜 | ½ cup | Natural, no added sugar |
| Powdered Sugar 🍚 | ¼ cup | For dusting, optional |
The bananas are the star—ripe is key (those brown spots mean sweetness). Grab 3 medium that feel soft when squeezed. Trader Joe's and Whole Foods usually have the riper ones, but any grocery store works. For the peanut butter, natural, no-sugar-added makes all the difference—Jif Natural or Skippy Natural are my go-tos. The butter? Full-fat, room temperature (microwave 40 seconds if cold). Don't skip sifting the flour—it keeps the crumb light. And the nutmeg? Freshly grated from a whole nut if you're feeling fancy, but pre-ground works fine too.
No vanilla extract? Vanilla bean paste works perfectly, or even a pinch of vanilla sugar. Short on baking powder? Baking soda plus cream of tartar at half the amount is a solid swap. The powdered sugar is totally optional—just dust it on after baking if you're feeling fancy. For a vegan version, swap the eggs for flax eggs (2 tbsp ground flax + 6 tbsp water) and use vegan butter. The peanut butter swirl can be almond butter or sunflower seed butter if you prefer. And if you're worried about the cake being too sweet, reduce the sugar to 3/4 cup—the bananas pack plenty of natural sweetness.
This cake keeps beautifully at room temperature for 3 days, wrapped in foil. For longer storage, refrigerate for up to 5 days or freeze for 3 months. I always slice it with a hot knife for clean cuts—just run it under hot water, wipe dry, and slice. The best part? It reheats perfectly in the microwave for 15 seconds to bring back that fresh-from-the-oven warmth. Make a double batch—it disappears fast around here.

Step-by-step instructions for banana cake loaf tin recipe
Here's how to create a moist banana cake with peanut butter swirls and a perfect golden crust.
Prepare the Banana Mixture
Start by mashing the 3 medium ripe bananas until smooth—no lumps should remain. I like to use a fork for this step, but a food processor works too. Transfer the mashed bananas to a mixing bowl and set aside. The riper the bananas, the sweeter and more flavorful your cake will be.
In a separate bowl, cream together the 0.75 cup unsalted butter and 1 cup granulated sugar using an electric mixer on medium speed for about 3-4 minutes. You'll see the mixture lighten in color and nearly double in volume. This step incorporates air, which helps create that tender crumb we're after. If your butter isn't room temperature, let it sit at room temperature for 30 minutes before starting.
Combine Wet and Dry Ingredients
Add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 1 teaspoon vanilla extract and the mashed bananas. The mixture will look thick and slightly curdled, but don't worry—it will come together when we add the dry ingredients.
In a separate bowl, whisk together the 2 cups all-purpose flour, 2 teaspoons baking powder, 1.5 teaspoons ground cinnamon, 0.25 teaspoon ground nutmeg, and 0.5 teaspoon salt. Sift the dry ingredients into the wet mixture in three additions, mixing on low speed just until combined. Overmixing develops gluten, which can make the cake dense. You should still see some flour streaks in the batter.
Fold in Peanut Butter and Prepare the Loaf Tin
Remove the mixing bowl from the mixer and gently fold in the 0.5 cup creamy peanut butter using a silicone spatula. The peanut butter adds richness and creates those beautiful swirls we want. Be careful not to overmix—just combine until evenly distributed throughout the batter.
Preheat your oven to 350°F. Lightly grease a 9x5-inch loaf tin with butter or line it with parchment paper. Dust the tin generously with flour, tapping out any excess. Pour the batter into the prepared tin and smooth the top with a spatula. This ensures even baking and a level cake.
Create the Peanut Butter Swirls
Here's where the magic happens: use the back of a spoon to create 4-5 wells in the batter, about 1 inch apart. Drop 1 teaspoon of peanut butter into each well, then gently swirl the batter with a knife or skewer to create marbled patterns. The peanut butter will sink slightly, creating those beautiful swirls throughout the cake.
Bake for 50-55 minutes, or until a toothpick inserted into the center comes out clean. The cake should be golden brown on top and spring back slightly when pressed. If the top browns too quickly, tent the cake with foil after 30 minutes to prevent over-browning.
Cool and Finish
Remove the cake from the oven and let it cool in the tin for 10 minutes. Then transfer it to a wire rack to cool completely. While it cools, mix together 0.25 cup powdered sugar with 1 tablespoon milk (or water) to create a simple glaze. Drizzle this over the cooled cake for a sweet, glossy finish.
Slice the cake into 8 equal portions and serve warm or at room temperature. The peanut butter swirls should be visible throughout each slice, and the texture should be moist and tender with a slightly crispy crust. Store any leftovers in an airtight container for up to 3 days or freeze for longer storage.
Pro Tips For Making Banana Cake Loaf Tin
- Mash Bananas Properly: Don’t just chop them—squish those bananas through a fork until smooth, with no visible chunks. I learned this the hard way when I left tiny banana bits in the batter, and they’d turn into dry, rubbery pockets in the cake. A quick pulse in a food processor saves time and guarantees even texture.
- Weigh Your Butter: Unsalted butter varies in density, and eyeballing it leads to dry cakes. Use a kitchen scale for 225g total (softened, not melted) to avoid guessing. I was skeptical until I tried it—now my loaf always bakes up moist and tender, not greasy or crumbly.
- Check Doneness Early: Banana cakes sink in the middle as they cool, so pull yours out when the edges are just pulling away and the center reads 190°F (88°C). Tent with foil the last 10 minutes if the top browns too fast—this prevents overbaking while keeping the crumb soft.
- Swap Brown Sugar: Replace half the granulated sugar with light brown sugar for deeper flavor and a slightly chewy texture. It’s a tiny tweak that makes the cake taste less sweet and more complex—like the difference between a basic loaf and one that feels special. (Yes, even if you’re impatient like me.)
Storing and reheating this banana cake loaf tin
Room Temperature Storage
This cake stays fresh and delicious at room temperature for up to 3 days when wrapped tightly in plastic wrap or aluminum foil. I like to use a 9x5-inch loaf pan cover to seal it completely—this prevents drying and keeps the texture perfect. Store it in a cool, dark place like a pantry away from direct sunlight, which can dry out the crust too quickly. For extra protection, place the wrapped cake in a bread box or airtight container with a paper towel to absorb any moisture. 🌟
Refrigerator Storage
If you need to keep your banana cake longer than 3 days, refrigerate it for up to 5 days. Wrap it tightly in plastic wrap and place it in the fridge—this helps maintain moisture and prevents the peanut butter swirls from becoming too soft. To serve, let slices sit at room temperature for 10-15 minutes before enjoying, as cold temperatures can make the cake slightly dense. I always reheat slices in the microwave for 10-15 seconds to restore that fresh-baked warmth. 🔥
Freezer Storage
For maximum shelf life, freeze your banana cake for up to 3 months. Wrap it tightly in plastic wrap, then place it in a freezer-safe bag or airtight container to block out air and moisture. Label the bag with the date to keep track. When ready to serve, thaw overnight in the fridge or reheat frozen slices directly in the microwave for 20-25 seconds—this brings back the moisture and softness. Avoid thawing at room temperature, as condensation can make the cake soggy. ✨
Reheating Tips
Microwaving is the fastest way to revive your cake. Place a slice on a microwave-safe plate, cover it loosely with a damp paper towel, and heat for 10-15 seconds. This method keeps the crust from drying out while warming the center. For a stovetop approach, heat a dry skillet over low heat and warm the slice for 2-3 minutes—flip once to ensure even heating. Always reheat to 165°F to kill any bacteria and restore freshness. 💡
Slicing Tricks
Use a hot knife for clean, professional slices every time. Run your knife under hot water, wipe it dry, and slice through the cake—this prevents crumbs and gives you neat edges. For the first cut, angle the knife slightly to create a domed slice that showcases the peanut butter swirls. If your cake has cooled completely, let it sit at room temperature for 5 minutes before slicing to avoid tearing the layers. A serrated knife works best for this recipe. 🔪

Frequently asked questions
Why does my banana cake turn out dense?
Overmixing the batter develops gluten, which makes the cake dense. Mix the dry ingredients just until combined—you should still see flour streaks. Also, ensure your bananas are ripe (soft with brown spots) and don't overfill the loaf tin. The batter should reach about 2/3 full for proper rising.
Can I substitute peanut butter with another nut butter?
Almond butter or sunflower seed butter work beautifully. For a richer flavor, use the same amount. If using almond butter, add 1 teaspoon of oil to keep the texture moist. The swirl technique remains the same—just adjust the consistency slightly if needed.
How do I know when the cake is fully baked?
Insert a toothpick into the center—it should come out clean or with just a few moist crumbs. The cake should also spring back slightly when pressed gently. Bake for 50-55 minutes at 350°F, but check after 45 minutes since ovens vary. A golden-brown top indicates doneness.
Can I make this cake without eggs?
Yes! Replace the 2 eggs with 2 flax eggs (2 tbsp ground flaxseed + 6 tbsp water) or 1/4 cup unsweetened applesauce. Let the flax mixture sit for 5 minutes to thicken before using. The texture may be slightly denser, but it will still be moist and delicious.
What’s the best way to slice the cake for clean pieces?
Use a hot knife for perfect slices. Run your knife under hot water, wipe it dry, and slice through the cake. For the first cut, angle slightly to create a domed slice that showcases the peanut butter swirls. Let the cake cool completely before slicing to avoid tearing. A serrated knife works best.
