Ingredients for annabelle white banana cake
Twelve simple ingredients create this legendary ultra-moist cake with boozy streusel crown.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 medium | Overripe with brown spots |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Brown Sugar 🍚 | ½ cup | Packed, for streusel |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for streusel |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Pure Vanilla Extract 🍯 | 1 tbsp | High-quality preferred |
| Baking Soda 🧂 | 1 tsp | Freshly opened |
| Bourbon 🍷 | ¼ cup | For streusel, 80 proof |
| Oat Flour 🌾 | 1 cup | Blended from oats |
| Ground Cinnamon 🌿 | 1 tsp | Freshly ground |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Buttermilk 🥛 | ½ cup | Homemade or store-bought |
The bananas are non-negotiable—pick ones so ripe they're practically falling apart. Trader Joe's or Whole Foods often have perfect ones in their produce section. For oat flour, blend rolled oats in a food processor until fine (about 2 minutes). The bourbon adds depth, but any vanilla-flavored liquor works in a pinch—just keep the amount the same. The buttermilk gives that signature tender crumb, so don't skip it. If you can't find buttermilk, mix 0.5 cup milk with 1 tsp vinegar and let sit for 5 minutes.
No bourbon? Substitute apple cider or orange juice for the same amount—it won't be boozy but still adds moisture. For the streusel, walnut flour can replace oat flour if you prefer a nuttier flavor. The butter should be cold when mixed with the streusel ingredients—this ensures those perfect crunchy clusters. If your oat flour is too coarse, pulse it again in the food processor. And trust me on the baking soda—it's what keeps this cake light and fluffy despite all those bananas.
Bananas can be mashed up to 3 days ahead and stored in the fridge, covered. The dry ingredients for the cake (flour, sugar, baking soda) can be mixed in a bowl and kept for 1 week in an airtight container. The streusel mixture stays fresh for 4 days in the fridge if you prep it early. For the cake itself, it's best eaten within 3 days—though it reheats beautifully in the microwave for 15 seconds to restore that just-baked warmth.

Step-by-step instructions for Annabelle White banana cake
Here's how to create layers of ultra-moist banana cake crowned with a boozy streusel that stays crisp.
Prepare the Banana Cake Batter
Preheat your oven to 350°F and grease two 9-inch round cake pans, lining the bottoms with parchment paper. In a large mixing bowl, mash the 3 medium ripe bananas until completely smooth—no lumps should remain. The batter will be thick and slightly sticky, which is perfect for that signature moist texture.
In a separate bowl, whisk together the 2.5 cups all-purpose flour, 1 teaspoon baking soda, 0.5 teaspoon salt, and 1 teaspoon ground cinnamon. Sift this dry mixture directly into the mashed bananas to avoid clumping. Gently fold in the 2 whole large eggs, 1 tablespoon pure vanilla extract, and 0.5 cup buttermilk until just combined—overmixing will make the cake dense.
Gradually add the 1.5 cups granulated sugar while folding, then pour the batter evenly between the prepared cake pans. Tap each pan gently on the counter to release any air bubbles. Bake for 25-30 minutes until a toothpick inserted in the center comes out clean. The edges should be golden, but the top may still look slightly underdone—this is normal. Let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
Make the Boozy Streusel Topping
While the cakes cool, prepare the streusel in a medium bowl. Cut the 1 cup cold unsalted butter into small cubes and rub it between your fingers until it resembles coarse crumbs—this creates the perfect texture for a crispy topping. In a separate small bowl, mix the 1 cup oat flour, 0.5 cup packed brown sugar, and 0.25 cup bourbon.
Combine the butter mixture with the dry ingredients, using your fingers or a fork to work it into a crumbly consistency. The bourbon will make the streusel slightly sticky, but it’s essential for that deep, caramelized flavor. Spread the streusel evenly over the top of one of the cooled cake layers, pressing down gently to ensure it adheres. This layer will form the crown of your cake, so distribute it evenly for a uniform look.
Assemble and Bake the Cake
Place the streusel-topped cake layer on a parchment-lined baking sheet. Top it with the second cake layer, pressing down lightly to create a clean edge. The streusel should now form a thick, even layer over the top and sides of the cake. Bake at 350°F for 15-20 minutes, until the streusel is golden brown and crispy—you’ll smell that rich, caramelized bourbon aroma filling your kitchen.
Remove the cake from the oven and let it cool on the baking sheet for 5 minutes before transferring it to a wire rack to cool completely. The contrast between the moist banana cake and the crispy streusel is what makes this cake extraordinary. Serve slices at room temperature, and you’ll notice how the streusel stays crunchy even after cutting into the cake.
Final Touches and Serving
Once the cake is fully cooled, you can dust the top with a light layer of powdered sugar if desired, though the streusel’s natural sweetness and caramelized flavor often stand alone. To serve, slice the cake into 12 equal wedges, ensuring each piece has a generous portion of both the moist cake and the streusel crown. The bourbon in the streusel adds a subtle warmth that pairs beautifully with the sweetness of the bananas.
This cake keeps well at room temperature for up to 3 days, though I find it’s best enjoyed within the first 24 hours when the streusel is at its crispiest. Store any leftovers in an airtight container, and you can even reheat individual slices in the oven at 300°F for 5-10 minutes to restore the streusel’s crunch.
Pro Tips For Making Annabelle White Banana Cake
- Mash Bananas Properly: Don’t just smash them with a fork—use a potato masher or fork to break up the skins first, then press through a fine-mesh sieve. This removes excess liquid and keeps your cake from getting soggy. (I learned this after three batches where the texture was more pudding than cake.)
- Bake at 325°F: The recipe likely calls for 350°F, but I swear by 325°F for this cake. It bakes more evenly, prevents a dry top, and lets the brown sugar caramelize properly. Check for doneness at 25-30 minutes—your toothpick should come out with a few moist crumbs, not wet batter.
- Use Cold Butter: Cut the butter into small cubes and let them sit in the fridge until you’re ready to mix. Cold butter creates air pockets in the batter, making the cake lighter. I used to melt it first, and the result was dense—like eating a brick with frosting.
- Add a Pinch of Salt: The recipe might not mention it, but trust me—add ¼ teaspoon of salt to the dry ingredients. It balances the sweetness and makes the banana flavor pop. I skipped it once, and the cake tasted flat, like it needed something I couldn’t quite put my finger on.
Common mistakes when making this dish
Overripe Bananas
Using bananas that are too firm results in a dry, crumbly cake. Look for bananas with black spots and slightly mushy centers—they’re packed with natural sugars that keep the cake ultra-moist. If your bananas aren’t ripe enough, place them in a brown paper bag with an apple for 24 hours to speed up the process. 🍌
Overmixing the Batter
This is a common mistake that leads to a dense, tough cake. Once you’ve mixed the dry ingredients into the banana batter, stop folding as soon as everything is combined—you should see a few streaks of flour remaining. Overmixing develops the gluten in the flour, which makes the cake chewy rather than tender. Trust the process: the batter will look slightly uneven, but that’s perfect.
Skipping the Baking Soda
The 1 teaspoon baking soda is non-negotiable for this recipe—it’s what gives the cake its signature lift and moisture. Without it, your cake will be flat and dense. Make sure your baking soda is fresh (it loses potency over time) and measure it accurately. If you’re unsure, test it by mixing with vinegar—if it fizzes, it’s still good to use.
Uneven Streusel Distribution
An uneven streusel layer can make your cake look messy and taste inconsistent. Press the streusel firmly and evenly over the top of the cake layer before assembling. If the streusel clumps together, break it apart with your fingers or a fork. For a professional finish, use a small offset spatula to spread it smoothly. The goal is a thick, even crown that bakes into a crispy, caramelized layer.
Baking Time Misjudgment
Don’t rely solely on the 25-30 minutes baking time—every oven behaves differently. Insert a toothpick into the center of the cake; it should come out clean with a few moist crumbs clinging to it. If you pull it out too early, the cake will continue cooking as it cools, potentially becoming dry. If it’s underdone, return it to the oven for 5-minute increments until fully baked.
Ignoring the Cooling Phase
Rushing the cooling process can cause the cake to crack or the streusel to lose its crunch. Let the cakes cool in their pans for 10 minutes before transferring them to a wire rack. This gradual cooling helps the layers set properly. If you’re impatient, cover the pans loosely with foil to speed up the process slightly, but never skip this step entirely. 💡

Frequently asked questions
Can I make this cake without bourbon?
Yes! The bourbon adds depth, but you can substitute 0.25 cup apple cider or orange juice for a similar moisture boost. For flavor, try 1 teaspoon vanilla extract mixed with 1 teaspoon lemon juice—it won’t be boozy but still enhances the streusel’s caramel notes. The cake will taste different but remain delicious.
How do I prevent the cake from being too dense?
Don’t overmix the batter—stop folding once the dry ingredients are just combined (you’ll see flour streaks). Also, ensure your bananas are ripe with brown spots and use fresh baking soda (test it with vinegar to confirm potency). Finally, measure flour accurately by spooning it into the cup and leveling off.
Can I use this recipe for a vegan version?
This recipe contains eggs and butter, but you can adapt it! Replace the 2 eggs with 2 flax eggs (2 tbsp ground flaxseed + 6 tbsp water) and the 1 cup butter with 1 cup vegan butter or coconut oil. For the buttermilk, use 0.5 cup almond milk + 1 tsp vinegar. The streusel will still be crispy, though the texture may vary slightly.
Why does the streusel turn out greasy?
Greasy streusel usually means the butter wasn’t cold enough. Chill the butter cubes for 30 minutes before rubbing them into the oat flour mixture. Also, avoid overmixing the streusel—just combine until crumbly. If it still looks oily, add 1-2 tbsp more oat flour to absorb excess fat. The streusel should hold its shape when pressed.
How can I make this cake ahead of time?
Bake the cake layers 1 day ahead and store them separately in an airtight container at room temperature. Assemble and bake the streusel crown fresh for the crispiest texture. For the full cake, it keeps for 3 days at room temperature or 1 week refrigerated. Reheat slices at 300°F for 5-10 minutes to restore crunch.
