Ingredients for anna olson banana cake
Ripe bananas, warm spices, and tender crumb—this cozy cake needs just a few pantry staples.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 medium | Mashed to 1.5 cups |
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | Light brown sugar works too |
| Unsalted Butter 🧈 | 1 cup | Softened to room temp |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Pure Vanilla Extract 🌿 | 1 tbsp | Imitation-free for best flavor |
| Ground Cinnamon 🌶️ | 2 tsp | Freshly ground preferred |
| Baking Soda 🧂 | 1 tsp | Not baking powder |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Powdered Sugar 🍚 | ½ cup | For optional glaze |
| Heavy Cream 🥛 | ½ cup | For optional glaze |
| Lemon Juice 🍋 | 1 tbsp | Brightens banana flavor |
The bananas are non-negotiable here. Spot them by their speckled yellow skins—they should be soft enough to yield slightly when pressed. Trader Joe's and Whole Foods usually have the ripest selection, but check your grocery store's produce section first. If you can't find perfectly ripe ones, place them in a paper bag with an apple overnight—the ethylene gas will speed up the ripening process. The butter should be soft but not melted—press a finger into it, and it should leave a slight indent. For the flour, King Arthur or Gold Medal brands are my go-to—they're consistently reliable for tender cakes.
No vanilla extract? Vanilla bean paste or even vanilla sugar will work in a pinch—just adjust the amount to taste. The cinnamon is key for that warm spice note, but if you're out, nutmeg or pumpkin pie spice can substitute at half the amount. For the glaze, if you're skipping it, the cake still tastes amazing dusted with extra powdered sugar right after baking. The eggs should be room temperature—cold eggs can cause the batter to curdle. If you're worried about overmixing, mix just until combined—the batter will look slightly lumpy, and that's perfect for a tender crumb.
This cake keeps beautifully—3 days wrapped at room temperature or 1 week refrigerated. For longer storage, freeze slices wrapped in plastic for up to 3 months. I always bake mine in a 9-inch round pan for perfect portions, but a loaf pan works too if you prefer. The glaze, if made, should be used within 2 days—it's best fresh. Leftovers reheat wonderfully in the microwave for 10 seconds to restore moisture.
Why You'll Love This Recipe

- No Mash Needed: Honestly, I just smash those ripe bananas right in the bowl with a fork—no food processor, no fuss. The flour and butter handle the rest while you’re still scraping the last bits off the fork.
- Moisture Locked In: Between us, this cake stays tender for days. The bananas add natural sweetness and moisture, while the butter keeps it rich without drying out. (Yes, even on a Tuesday night.)
- Breakfast or Dessert: I’ll be real: this works for both. Serve it warm with a scoop of ice cream for dessert, or slice it cold with peanut butter for a grab-and-go breakfast. The eggs in the batter make it sturdy enough for either.
Step-by-step instructions for Anna Olson's banana cake
Here's the method for a perfectly moist banana cake with warm spice notes every time.
👨🍳 Step 1: Prepare the Banana Mixture
Mash the 3 medium ripe bananas until completely smooth—no lumps should remain. I press them through a fine-mesh sieve for extra-silky texture. In a separate bowl, whisk together the 1.5 cups granulated sugar, 1 cup softened unsalted butter, and 1 tbsp pure vanilla extract until light and fluffy.
This creaming process incorporates air, which helps create tender layers. The butter should look pale and nearly doubled in volume. Stir in the mashed bananas and 1 tbsp lemon juice—this brightens the flavor and balances the sweetness. Set aside while you prepare the dry ingredients.
👨🍳 Step 2: Combine Wet and Dry Ingredients
In a large mixing bowl, sift together the 2 cups all-purpose flour, 2 tsp ground cinnamon, 1 tsp baking soda, and 0.5 tsp salt. Make a well in the center and add the banana mixture. Gently fold everything together using a spatula—don't overmix.
Overmixing develops gluten, which makes the cake dense. You'll see streaks of flour, but that's okay—they'll disappear when you bake. The batter should be thick but pourable. If it looks too stiff, add 1-2 tablespoons of milk to loosen it slightly.
🔥 Step 3: Bake to Golden Perfection
Preheat your oven to 350°F and grease two 8-inch round cake pans or line them with parchment paper. Divide the batter evenly between the pans and smooth the tops. Bake for 30-35 minutes until a toothpick inserted in the center comes out clean.
Here's the thing—banana cakes can dry out if overbaked. Watch for the edges to pull away from the pan and the top to spring back when touched lightly. If the top browns too quickly, loosely tent with foil after 20 minutes to prevent over-browning.
⏰ Step 4: Cool and Prepare Optional Glaze
Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then transfer to a wire rack to cool completely. While they cool, prepare the optional glaze by whisking together the 0.5 cup powdered sugar and 0.5 cup heavy cream until smooth.
Drizzle the glaze over the cooled cake layers just before serving. The glaze adds a sweet contrast to the warm spices. If you prefer a less sweet finish, skip the glaze or reduce the powdered sugar to 0.25 cup. The cake tastes delicious either way—this is just the finishing touch.
🍽️ Step 5: Assemble and Serve
Once completely cooled, slice the cakes horizontally and spread a thin layer of banana mixture between the layers if desired. Dust with additional cinnamon for extra warmth. Serve at room temperature with a dollop of whipped cream or a scoop of vanilla ice cream.
The cake should be moist with tender crumbs and a subtle banana flavor that's balanced by the cinnamon. Each slice should hold together well without being dry or crumbly. Store leftovers in an airtight container for up to 3 days—though I doubt they'll last that long!
Pro Tips For Making Anna Olson Banana Cake
- Mash Bananas Thoroughly: I learned this the hard way—lumpy banana purée means uneven texture, and nobody wants cake with surprise banana chunks. Use a fork first, then press through a fine-mesh sieve if you’re impatient like me (yes, it’s faster than blending).
- Butter Should Be Cool: Room temperature butter creams better, but don’t overdo it—if it’s too soft, your cake will spread like a pancake. Stick it in the fridge for 10 minutes after softening, then test: press your finger in; it should leave a slight dent but not flatten completely.
- Don’t Overmix the Batter: This isn’t a science experiment. Mix just until the flour disappears—overworking it turns your tender cake into a chewy brick. Fold in the dry ingredients with a spatula after combining wet ingredients; stop when streaks disappear, not when you’re bored.
- Bake Until the Center Springs: The recipe says "done," but trust the toothpick test instead. Insert it in the center—if it comes out with a few moist crumbs (not wet batter), pull it out. Overbaking dries out the cake faster than a summer day in Arizona, and you’ll regret it.
Pro cooking tips for this dish
Banana Ripeness Matters
The secret to this cake's moisture starts with the bananas—spot them by their speckled yellow skins with brown spots. I always press them through a fine-mesh sieve to eliminate lumps, which keeps the texture silky smooth.
If your bananas aren't ripe enough, place them in a paper bag with an apple overnight—the ethylene gas speeds up ripening. Overripe bananas with black spots? No problem—just peel off the black parts before mashing. 🍌
Butter Temperature Control
Your butter should be soft but not melted—press a finger into it, and it should leave a slight indent. I use Land O'Lakes unsalted butter because it's consistently reliable, but any good-quality brand works. If your kitchen is warm, chill the butter for 10 minutes before using.
Cold butter won't cream properly, leading to a denser cake. The goal is pale yellow butter that's light and fluffy when mixed with sugar.
Mixing Like a Pro
Overmixing is the enemy of tender cakes. After combining wet and dry ingredients, fold just until combined—the batter will look slightly lumpy, and that's perfect. I use a spatula to gently scrape the sides of the bowl to ensure everything incorporates evenly.
If the batter looks too stiff, add 1-2 tablespoons of milk to loosen it. The key is to preserve as much air as possible for a light crumb. 💫
Oven Prep for Even Baking
Preheat your oven to 350°F for at least 15 minutes before baking. I always grease my 8-inch round pans with coconut oil spray or line them with parchment paper for easy release. For even baking, place the pans on the middle rack of your oven.
If the top browns too quickly, loosely tent with foil after 20 minutes to prevent over-browning while keeping the center moist.
Glaze Timing Tips
The glaze should be used within 2 days for best texture. I whisk 0.5 cup powdered sugar and 0.5 cup heavy cream until smooth, then drizzle it over the completely cooled cake. For extra flair, dust with cinnamon or crushed nuts before serving.
If you prefer less sweetness, reduce the powdered sugar to 0.25 cup—the cake still tastes amazing without it. The glaze adds a professional touch but isn't required. ✨
Storage Secrets
This cake keeps beautifully—3 days wrapped at room temperature or 1 week refrigerated. For longer storage, freeze slices wrapped in plastic for up to 3 months. To reheat, microwave for 10 seconds to restore moisture.
I always bake extra slices because they disappear faster than you'd think! The flavors actually improve as the spices meld over time. 💡

Frequently asked questions
Why do I need perfectly ripe bananas for this cake?
Ripe bananas with brown speckles are sweeter and mash into a smoother texture that creates natural moisture in the cake. Underripe bananas make the cake dense, while overripe ones (with black spots) can make it too sweet. The perfect balance gives that signature tender crumb without needing extra sugar.
Can I substitute light brown sugar for granulated sugar?
Yes! Light brown sugar adds a subtle caramel flavor that pairs beautifully with the bananas. Use the same 1.5 cups measurement, but expect the cake to have a slightly deeper color and richer taste. Dark brown sugar works too but will make the cake denser.
What if my cake turns out dry?
Dryness usually means overbaking or underripe bananas. To fix it, brush warm slices with 2 tablespoons of simple syrup (equal parts sugar and water, heated until dissolved) or serve with whipped cream. For next time, reduce baking time by 2-3 minutes and use riper bananas.
Can I make this cake in a loaf pan instead?
Use a 9x5-inch loaf pan and reduce baking time to 25-30 minutes. The texture will be slightly denser but still moist. This version works great for quick breakfasts or as a side with coffee. Just check for doneness with a toothpick.
How do I make this cake egg-free?
Replace the 2 eggs with 2 tablespoons ground flaxseed mixed with 6 tablespoons water (let sit for 5 minutes to thicken). For best results, also add 1 teaspoon baking powder to compensate for lost lift. The texture will be slightly denser but still delicious.
