Ingredients for betty crocker banana bread recipe with sour cream
Fifteen ingredients create Betty Crocker's legendary moist banana bread with signature vanilla swirl.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for even texture |
| Granulated Sugar 🍚 | 1 ½ cups | Light brown sugar optional |
| Sour Cream 🥛 | 1 cup | Full-fat for best moisture |
| Ripe Bananas 🍌 | 3 medium | Mashed, skins removed |
| Unsalted Butter 🧈 | ½ cup | Melted, room temperature |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Vanilla Extract 🍯 | 2 tsp | Pure extract preferred |
| Baking Soda 🧂 | 1 tsp | Pure baking soda |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Bean Paste 🍯 | 1 tbsp | For swirl, optional |
| Powdered Sugar 🍚 | ¼ cup | For topping |
The sour cream is non-negotiable here—full-fat works best for that signature tender crumb. Trader Joe's and Whole Foods carry excellent quality, but any brand will do as long as it's not low-fat. Ripe bananas are essential for natural sweetness—look for ones with slightly soft spots but no bruising. The vanilla bean paste adds a professional touch; Nielsen-Massey is my go-to brand, but any high-quality paste will work. For the flour, King Arthur is my preference, but any all-purpose will suffice. The butter should be unsalted to control the final salt level, and it must be melted completely for the best texture.
No vanilla bean paste? Pure vanilla extract at double the amount works in a pinch. Substitute Greek yogurt for sour cream if needed, but expect a slightly denser texture. For the sugar, light brown sugar can replace half the granulated for a subtle molasses note. If you're short on ripe bananas, frozen bananas work perfectly—thaw and drain excess liquid first. The baking soda must be fresh; if it's more than six months old, it may not activate properly. For the cinnamon, ground is fine, but a quick pulse in a spice grinder with whole cinnamon sticks adds depth.
This loaf stays fresh for up to 5 days at room temperature, wrapped tightly in plastic. For longer storage, freeze individual slices wrapped in parchment—up to 3 months. The vanilla swirl keeps best if you bake it immediately after mixing; otherwise, cover and refrigerate for up to 24 hours. To reheat, wrap a slice in a damp paper towel and microwave for 10 seconds—restores that fresh-from-oven warmth. The powdered sugar topping should be sprinkled just before baking for maximum crunch.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this recipe because it’s literally 10 minutes of mixing—just fold the sour cream into the dry ingredients, mash those bananas, and let the batter do the work. No electric mixer, no stress, just smooth, tender crumb every time.
- Sour Cream Magic: Honestly, that tangy richness from the sour cream is the game-changer here. It keeps the bread ultra-moist for days (no dry, sad slices) and gives it that just-baked warmth that’s impossible to resist—especially when paired with a swipe of butter.
- Breakfast or Snack: Between us, this bread is my go-to for lazy mornings (toasted with peanut butter) or after-school snacks (cut into thick bars). It’s the same recipe, but it works for both—no need to bake two different things.
- Budget Baking Wins: I use this when I have overripe bananas and a half-stick of butter sitting in the fridge. The sour cream stretches the batter, so one loaf feeds my family for days, and the ingredients cost pennies compared to fancier recipes. Zero waste, all flavor.
Step-by-step instructions for Betty Crocker's sour cream banana bread
Here's how to bake a tender loaf with a perfect vanilla swirl and moist crumb every time.
Prepare the Banana Mixture
Mash the 3 medium ripe bananas in a medium bowl until completely smooth. You want no lumps—this ensures an even texture in your bread. Add the 2 teaspoons vanilla extract and mix well. Set this mixture aside while you prepare the other ingredients.
I like to use ripe bananas with just a few brown spots—this gives the best natural sweetness and flavor. If your bananas are too firm, let them sit at room temperature for 15-20 minutes before mashing to soften them slightly.
Mix the Dry and Wet Ingredients
In a large mixing bowl, whisk together the 2.5 cups all-purpose flour, 1 teaspoon baking soda, 2 teaspoons ground cinnamon, and 0.5 teaspoon salt. This dry mixture should be completely combined with no flour clumps remaining.
In a separate bowl, combine the 1 cup sour cream, 1.5 cups granulated sugar, 0.5 cup melted unsalted butter, and the 2 whole large eggs. Whisk until smooth and fully incorporated. The mixture should be thick but pourable. Gradually add the dry ingredients to the wet mixture, mixing just until combined—overmixing develops gluten and makes the bread dense.
Fold in Bananas and Create the Swirl
Gently fold the mashed banana mixture into the batter until just combined. Be careful not to overmix—you want to preserve some air in the batter. For the swirl, divide the batter evenly between two medium bowls. To one bowl, add 1 tablespoon vanilla bean paste and mix lightly to create a marbled effect.
Here's the thing—this swirl is what makes the bread special. The vanilla bean paste adds depth of flavor and creates beautiful marbling throughout the loaf. If you don't have vanilla bean paste, you can simply add an extra teaspoon of vanilla extract to one portion of the batter for a similar effect.
Bake to Golden Perfection
Preheat your oven to 350°F and grease a 9x5-inch loaf pan thoroughly with butter or cooking spray. Pour half of the plain batter into the prepared pan, spreading it evenly. Then carefully spoon the vanilla-infused batter over the top, creating a marbled effect with a spoon or knife.
Bake for 50-60 minutes until a toothpick inserted into the center comes out clean and the top is golden brown. The bread is done when it springs back slightly when pressed gently in the center. If the top browns too quickly, tent the pan with aluminum foil to prevent overbrowning while it continues to cook.
Cool and Serve
Remove the bread from the oven and let it cool in the pan for 10 minutes. Then transfer it to a wire rack to cool completely. This cooling period is crucial—it allows the bread to set properly and prevents it from becoming gummy.
Once cooled, dust the top with 0.25 cup powdered sugar for a sweet finish. The bread should have a moist crumb with a tender texture and that beautiful vanilla swirl throughout. Slice and serve warm for the best experience—this is when the bread is at its most flavorful and moist.
Pro Tips For Making Betty Crocker Banana Bread Recipe With Sour Cream
- MEASURE SOUR CREAM COLD: The recipe calls for sour cream, but I learned the hard way—warm it up even slightly, and your bread turns dense. Scoop it straight from the fridge, measure it, then stir it into the wet ingredients last. That tang stays sharp, and the texture stays light.
- MASH BANANAS UNTIL SMOOTH: Lumpy banana puree means uneven texture. Mash those bananas until there’s no resistance left—no visible chunks, no resistance when you press the spoon down. I used to rush this, and the bread had weird pockets of dryness. Take the extra 30 seconds.
- DON’T OVERMIX THE BATTER: Once you fold in the flour, stop. Two or three gentle stirs until just combined is all it takes. Overmixing develops gluten, and your banana bread turns into a tough, cake-like brick. The recipe’s leavening relies on that tender crumb—don’t mess with it.
- BAKE UNTIL TOOTHPICK COMES OUT CLEAN: The recipe’s baking time is a starting point, not a rule. Insert a toothpick into the center when the edges look done—if it comes out with moist crumbs, bake another 3–5 minutes. I’ve pulled loaves early too many times, and dry, gummy centers are a nightmare. Better to wait.
Pro cooking tips for betty crocker banana bread recipe with sour cream
Sour Cream Magic
The 1 cup sour cream is the game-changer in this recipe—it replaces traditional yogurt and adds fat that keeps the crumb ultra-moist. I always use full-fat sour cream (look for brands like Kroger or Great Value for budget-friendly options) because low-fat versions won't deliver that signature tender texture.
The fat content also helps create a cake-like crumb rather than a dense one. 🥛
For best results, use room-temperature sour cream. Cold sour cream can cause the batter to curdle when mixed with melted butter.
If your batter looks too thick after adding the dry ingredients, let it rest for 5 minutes before folding in the bananas—this allows the flour to fully hydrate and creates a smoother texture.
Banana Ripeness Check
Ripe bananas are non-negotiable for flavor and moisture. Look for bananas with slightly soft spots and a few brown specks—they'll be sweeter and mash more easily.
I like to peel and mash them directly in the bowl with a fork, then press through a fine-mesh sieve to remove any remaining lumps. This step ensures an ultra-smooth batter that bakes evenly. 🍌
If you're using frozen bananas, thaw them first and drain any excess liquid that forms during thawing. Too much liquid in the batter can make the bread gummy. For extra insurance, place a paper towel under the sieve when mashing to absorb excess moisture.
Vanilla Swirl Technique
The vanilla swirl transforms this from a simple banana bread to a showstopper dessert. After dividing the batter, I add 1 tablespoon vanilla bean paste (like Nielsen-Massey) to half the batter and gently swirl it with a knife before baking.
This creates beautiful marbling that peeks through in every slice. If you don't have vanilla bean paste, add 1 extra teaspoon of pure vanilla extract to one portion instead. 🍯
For a more professional look, use a skewer or chopstick to drag the vanilla-infused batter through the plain batter in the pan, creating ribbons. This technique requires patience but makes the final presentation stunning. The swirl should be visible but not overpowering—think delicate ribbons rather than thick streaks.
Oven Temperature Tips
Preheat your oven to 350°F for at least 15 minutes before baking—this ensures even heat distribution. I always use an oven thermometer to verify accuracy, as home ovens often run 25°F hotter or colder than set.
For a 9x5-inch loaf pan, place it on the middle rack where heat circulates evenly. 🌡️
If the top browns too quickly, tent the pan with aluminum foil after 30 minutes of baking. This prevents overbrowning while allowing the center to cook through.
The bread is done when a toothpick inserted in the center comes out clean or with just a few moist crumbs—this usually takes 50-60 minutes depending on your oven.
Cooling and Serving
Let the bread cool in the pan for 10 minutes before transferring to a wire rack. This prevents the loaf from collapsing as it sets. I find that cooling completely before slicing (about 1-2 hours) gives the cleanest cuts and prevents the bread from falling apart.
The first slice is always the hardest to resist—it's that good! 🍞
For serving, dust the top with powdered sugar right before slicing to add a sweet finish. The bread keeps well at room temperature for up to 5 days wrapped in plastic, or you can freeze individual slices for up to 3 months.
To reheat, wrap a slice in a damp paper towel and microwave for 10-15 seconds—this restores that fresh-from-oven warmth.

Frequently asked questions
Why does sour cream make this banana bread so moist?
The 1 cup sour cream adds fat and protein that keeps the crumb tender and prevents drying. Unlike yogurt, it creates that signature cake-like texture while adding richness. The fat content also helps retain moisture for days after baking.
Can I substitute Greek yogurt for sour cream?
Yes, but expect a slightly denser texture. Use the same amount of Greek yogurt, but let it sit at room temperature for 10 minutes first to prevent curdling. For best results, stick with full-fat sour cream—it delivers that classic Betty Crocker-style moistness.
How do I know when my banana bread is fully baked?
Insert a toothpick into the center—it should come out clean or with just a few moist crumbs. The top should also be golden brown and spring back slightly when pressed gently. Baking times vary, but 50-60 minutes at 350°F is standard for a 9x5-inch loaf pan.
What if my bread turns out too dense?
Overmixing or using cold ingredients often causes dense bread. Make sure to fold the batter gently (just until combined) and use room-temperature eggs, butter, and sour cream. Also, don't skip the 10-minute cooling period in the pan—rushing this step can make the crumb gummy.
Can I make this recipe in a different pan size?
For a 8x4-inch pan, reduce baking time by 10-15 minutes (about 40-45 minutes). For a 10x5-inch pan, increase time by 10-15 minutes (about 60-65 minutes). Always use an oven thermometer to ensure accuracy—home ovens often vary by 25°F from the set temperature.
