Ingredients for banana nut cake recipe betty crocker
Classic Betty Crocker flavors with a perfect walnut crown—simple ingredients for legendary cake layers.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 whole | Spotty and fragrant, not firm |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Packed Brown Sugar 🍚 | 1 cup | Light or dark variety |
| Unsalted Butter 🧈 | 1 cup | Room temperature, full-fat |
| Large Eggs 🥚 | 2 whole | Room temperature, beaten |
| Vanilla Extract 💧 | 2 tsp | Pure alcohol-free preferred |
| Baking Soda 🧂 | 1 tsp | Diamond Crystal preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Chopped Walnuts 🥜 | 1 ½ cups | Toasted for extra flavor |
| Old-Fashioned Oats 🌾 | 1 cup | Not quick oats |
| Packed Brown Sugar 🍚 | ½ cup | For streusel topping |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for streusel |

The bananas are non-negotiable—ripe and speckled is the magic. Grab them when they're soft but not mushy. Trader Joe's or local markets often have the sweetest ones. For the walnuts, toasted in a dry pan for 5 minutes makes all the difference—crunchier and more flavorful. If you're short on time, the pre-toasted kind from the baking aisle works too. The butter? Full-fat only—this isn't the place for low-fat shortcuts. Room temperature is key—press it to test if it's ready (should leave a slight indentation).
No vanilla extract? Seeds from 1 vanilla bean or 1 tsp vanilla sugar works in a pinch. Substituting the walnuts? Pecans or macadamias work beautifully, but walnuts give that classic Betty Crocker crunch. The oats? Old-fashioned only—quick oats get mushy. For the streusel, if you're feeling fancy, add 1 tbsp flour to the topping mix for extra crispiness. And yes, the brown sugar in the streusel is lighter than the cake batter—don't swap it out. The cinnamon? Penzeys or McCormick are my go-tos for that warm spice note.
This cake keeps 5 days wrapped at room temperature—perfect for gifting. For longer storage, freeze the whole cake in slices for up to 3 months. I like to wrap each slice individually with parchment before freezing. The streusel topping stays crisp even after baking, but if you want extra crunch, bake the cake 5 minutes longer. Serve warm with vanilla ice cream or at room temperature with whipped cream—either way, it's a crowd-pleaser.

Step-by-step instructions for Betty Crocker's banana nut cake
This classic cake delivers perfect moist layers and a crunchy walnut streusel crown—every time!
👨🍳 Step 1: Mash Bananas and Mix Wet Ingredients
Start by mashing the 3 whole ripe bananas in a large mixing bowl until completely smooth—no lumps! I like to use a fork for this step, pressing hard to break down all the fibers. The bananas should look like thick pudding at this point.
In a separate bowl, whisk together the 1 cup unsalted butter (room temperature), 2 cups granulated sugar, and 1 cup packed brown sugar until light and fluffy—about 3-4 minutes with an electric mixer. This creaming process incorporates air, which helps create that tender cake texture we're after. Add the 2 whole large eggs one at a time, mixing well after each addition, then stir in the 2 teaspoons vanilla extract. Finally, combine the wet ingredients with the mashed bananas.
👨🍳 Step 2: Combine Dry Ingredients and Fold Gently
In a medium bowl, sift together the 2½ cups all-purpose flour, 1 teaspoon baking soda, and ½ teaspoon salt. This sifting step prevents lumps and ensures even distribution of leavening. Gradually add the dry ingredients to the wet mixture, mixing on low speed just until combined—about 30 seconds. Be careful not to overmix, or you'll develop gluten and end up with a tough cake.
Fold in the 1½ cups chopped walnuts by hand using a spatula. I like to distribute them evenly throughout the batter so every slice gets that wonderful nutty crunch. The batter will be thick but manageable—don't worry if it looks like too much, but trust me, it's perfect for creating that moist texture.
🥘 Step 3: Prepare the Walnut Streusel Topping
While the cake batter rests, make the streusel topping in a separate bowl. Cut the ½ cup unsalted butter (cold) into the 1 cup old-fashioned oats using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Add the ½ cup packed brown sugar and 1 teaspoon ground cinnamon, then mix until evenly combined. Finally, fold in the remaining ½ cup chopped walnuts—this is what will give your cake that beautiful crunchy crown.
Here's the thing—don't skip toasting the walnuts beforehand. The extra flavor makes all the difference in this classic recipe. If you have time, toast them in a dry skillet over medium heat for 3-4 minutes until fragrant before adding to the streusel.
🔥 Step 4: Bake in Layers for Perfect Texture
Preheat your oven to 350°F and grease two 9-inch round cake pans (or one 9x13-inch pan). Divide the cake batter evenly between the prepared pans. For the classic layered effect, sprinkle half of the streusel topping over each pan, pressing down gently with your fingers to help it adhere.
Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Here's my pro tip: I like to rotate the pans halfway through baking for even browning. The cake should be golden on top with that beautiful streusel crown looking crispy and inviting. If using a 9x13-inch pan, bake for 35-40 minutes instead.
⏰ Step 5: Cool and Serve for Maximum Moisture
Remove the cakes from the oven and let them cool in the pans for 10 minutes. This brief resting period prevents the cakes from cracking as they shrink. Then transfer to a wire rack to cool completely. I know it's tempting to dig in right away, but patience here ensures those moist layers stay perfect—no dry crumb here!
Once completely cool, frost with your favorite vanilla or cream cheese frosting if desired. The contrast of the moist cake layers with the crunchy walnut streusel crown makes every bite unforgettable. Store leftovers in an airtight container for up to 3 days, though I doubt they'll last that long!
Pro Tips For Making Banana Nut Cake Recipe Betty Crocker
- MASH THE BANANAS FIRST: I learned this the hard way—skipping the mash and just slicing bananas into the batter leaves you with a cake that’s more like a banana bread with nuts. Use a fork or potato masher to break them down completely, and let that mixture sit for 5 minutes before mixing with wet ingredients. The starch releases more, making the cake tender and moist.
- WEIGH THE FLOUR: That measuring cup in your drawer? It’s lying to you. Spooning flour into it packs it too tightly, and you’ll end up with a cake that’s dense and dry. Instead, use a kitchen scale for the Betty Crocker recipe’s flour requirement—it should be about 190 grams for most versions. If you’re stuck with cups, scoop the flour into the cup, then level it off with a knife. No, it’s not perfect, but it’s better.
- BAKE UNTIL THE TOOTHPICK TEST FAILS: The recipe says “until a toothpick comes out clean,” but with banana cake, that’s a trap. The cake will pull away from the edges but still be underdone inside. Insert the toothpick near the center—if it comes out with a few moist crumbs (not wet batter), that’s your cue. Overbaking turns banana cake gummy, and nobody wants that.
- SWAP THE BROWN SUGAR: Packed brown sugar is non-negotiable, but if you’re in a pinch, don’t grab the white sugar substitute. Instead, use dark brown sugar (it’s less sticky and packs better) or mix 1 cup white sugar with 1 tablespoon molasses. The molasses adds depth, and the cake won’t be as cloyingly sweet. Trust me, your taste buds will notice the difference.
Pro cooking tips for this dish
Banana Ripeness Matters
Never skip the spotty test! Choose bananas with dark brown speckles and a slightly soft peel—they're perfectly ripe for this cake. I grab mine from the grocery store's produce section when they're just starting to brown, usually 2-3 days after purchase. The riper the bananas, the more natural sweetness they add to the cake, reducing the need for extra sugar. If your bananas are too green, let them sit at room temperature for 1-2 days to ripen. 🍌
Butter Temperature Control
The secret to that light, fluffy texture starts with your butter. It should be soft but not melted—press your finger into it; if it leaves a slight indentation, it's ready. I like to take my butter out of the fridge 30 minutes before mixing. For the streusel topping, use cold cubed butter to prevent the mixture from turning into a paste. This keeps the streusel nice and crumbly. Don't substitute with margarine or low-fat butter—the fat content is crucial for that classic texture. 🧈
Streusel Texture Tricks
For the perfect streusel crown, use your fingers to work the cold butter into the oats until you get a coarse crumb texture. If the mixture feels too wet, add 1-2 tablespoons of flour to help bind it. Pressing the streusel gently into the cake batter before baking ensures it stays put and creates that beautiful crown. I like to toast my walnuts first—just 3-4 minutes in a dry skillet over medium heat—for extra flavor. This step makes all the difference in that nutty aroma. 🥜
Baking Time Precision
Your oven might run hot or cold, so always check for doneness with a toothpick. Insert it into the center of the cake—it should come out clean or with just a few moist crumbs. For 9-inch round pans, bake for 25-30 minutes, while a 9x13-inch pan will take 35-40 minutes. I rotate my pans halfway through baking for even browning. If the top browns too quickly, tent the pans with aluminum foil. The cake is done when it springs back slightly when touched. ⏰
Layering Like a Pro
Divide the batter evenly between pans to ensure consistent baking. For the classic layered look, sprinkle half the streusel over each pan before baking. Press it down gently with your fingers to help it adhere. If you're making a single-layer cake in a 9x13-inch pan, spread the batter evenly and sprinkle the entire streusel topping over the top. The key is to distribute the streusel evenly so every bite has that perfect crunch. 💫
Cooling for Perfect Texture
Let the cakes cool in their pans for 10 minutes before transferring to a wire rack. This brief rest prevents cracking as they shrink. Then, cool completely before frosting. I know it's tempting to dig in right away, but patience here ensures those moist layers stay perfect. The streusel topping will stay crisp if you resist cutting into the cake too soon. Once fully cooled, frost with vanilla or cream cheese frosting for that classic Betty Crocker touch. 🥧

Frequently asked questions
Can I substitute pecans for walnuts in the streusel?
Pecans work beautifully and add a slightly sweeter, buttery flavor. For best results, toast them first (just 3-4 minutes in a dry skillet) to enhance their natural sweetness. Use the same 1.5 cups total measurement—just chop them slightly finer than walnuts since they're softer. Macadamias also work well if you prefer a creamier texture.
Why does my banana nut cake turn out dense?
Overmixing is the most common culprit—mix the batter just until combined (30 seconds after adding dry ingredients). Another reason could be underripe bananas (they need to be speckled and soft) or using cold butter. Also, make sure your baking soda is fresh (old baking soda loses its lift). For extra moisture, try adding 2 tablespoons sour cream to the batter.
How do I make this cake gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill or King Arthur). Add ½ teaspoon xanthan gum to help bind the cake. For the streusel, use gluten-free oats and ensure your cinnamon is certified gluten-free. The texture will be slightly different but still delicious—expect a denser crumb.
Can I bake this cake in a bundt pan?
Yes! The batter works perfectly in a 10-12 cup bundt pan. Grease it thoroughly and bake at 350°F for 40-45 minutes. Skip the streusel topping (it won't adhere well) and instead sprinkle chopped nuts over the batter before baking. For a bundt version, I recommend adding 1 extra egg white to help the cake rise properly in the pan's walls.
What's the best way to store leftovers?
Wrap the cake tightly in plastic wrap or aluminum foil, then place it in an airtight container. It stays fresh at room temperature for 3-4 days. For longer storage, freeze individual slices wrapped in plastic wrap for up to 3 months. Thaw at room temperature for 1-2 hours before serving—no need for microwave reheating!
