Ingredients for joanna gaines banana cake
Six simple ingredients transform into Joanna Gaines' signature banana cake with tender crumb and warm vanilla aroma.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 2 cups | Mashed, about 3-4 medium bananas |
| All-Purpose Flour 🌾 | 2 cups | Sifted for even texture |
| Granulated Sugar 🍚 | 1 ½ cups | Light brown sugar optional |
| Buttermilk 🥛 | 1 cup | Room temperature for best results |
| Sour Cream 🍦 | ½ cup | Full-fat for richness |
| Pure Vanilla Extract 🍯 | 2 tsp | High-quality preferred |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground for warmth |
| Baking Soda 🧂 | 1 tsp | Pure baking soda |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vegetable Oil 🫒 | ½ cup | Light, not extra-virgin |
| Unsalted Butter 🧈 | ½ cup | Melted, room temperature |
The bananas are everything here—look for yellow with brown speckles for that perfect sweetness. Trader Joe's or your local grocery store's produce section usually has the ripest ones. If you can't find ripe enough, speed up the process by placing them in a paper bag for a day. The flour should be sifted to avoid dense spots in the cake—King Arthur or Gold Medal are reliable brands. For the vanilla, Nielsen-Massey or McCormick pure extract delivers that authentic flavor without artificial aftertaste.
No buttermilk? Mix 1 cup milk with 1 tbsp vinegar or lemon juice and let it sit for 5 minutes. Sour cream can be swapped for Greek yogurt in a pinch, but the cake will be slightly tangier. Light brown sugar adds subtle molasses notes—use it if you have it, but white sugar works perfectly fine. The cinnamon should be freshly ground if possible, but store-bought ground works too. For the oil, vegetable or canola oil keeps the cake moist without overpowering the banana flavor. If you're feeling fancy, substitute melted coconut oil for a subtle tropical twist.
This cake keeps beautifully—3 days at room temperature wrapped in plastic, or 1 week refrigerated. For longer storage, freeze slices wrapped individually for up to 3 months. The flavor actually improves after baking, so make it a day ahead for the best experience. I like to brush the top with a simple syrup (equal parts sugar and water, heated) before serving for extra moisture. Pair it with vanilla ice cream or a dollop of whipped cream for that classic Joanna Gaines touch.
Why You'll Love This Recipe
- No Mash Needed: I swear by this trick—just slice those ripe bananas right into the batter. No sticky mess, no peeling, and the sweetness? It’s like the cake already has its own built-in frosting.
- Moisture Magic: That buttermilk and sour cream combo keeps this cake tender for days. Not dry, not crumbly—just that perfect, fudgy crumb that makes you want to cut yourself another slice.
- Breakfast or Dessert: Honestly, I make this for both. Serve it warm with a drizzle of honey for breakfast, or dust it with powdered sugar for an after-dinner treat. The bananas make it feel special without needing frosting.
- Budget-Friendly Staples: You’re using pantry basics here—flour, sugar, bananas you’d buy anyway. No fancy ingredients, no wasted leftovers (if they even last that long). My wallet and my family thank me every time.
Step-by-step instructions for Joanna Gaines' banana cake
Here's how to achieve that signature moist crumb and perfect vanilla flavor Joanna Gaines is known for.
Mash the Ripe Bananas and Mix Wet Ingredients
Start by mashing the 2 cups ripe bananas in a large mixing bowl until completely smooth—no lumps should remain. This ensures an even distribution throughout the batter. In a separate small bowl, whisk together the 1 cup buttermilk, 0.5 cup sour cream, 0.5 cup vegetable oil, and 0.5 cup melted unsalted butter. The buttermilk and sour cream add richness while keeping the texture tender.
Add the wet ingredients to the mashed bananas and stir to combine. Then, mix in the 1.5 cups granulated sugar, 2 tsp pure vanilla extract, and 2 tsp ground cinnamon. The cinnamon will infuse warmth, while the vanilla extract enhances the natural banana flavor. This step creates the flavor foundation for the cake.
Combine Dry Ingredients and Fold Gently
In a medium bowl, sift together the 2 cups all-purpose flour, 1 tsp baking soda, and 0.5 tsp salt. Sifting prevents clumps and ensures an even texture. Gradually add the dry ingredients to the wet mixture, folding gently with a spatula just until combined. Avoid overmixing—this keeps the crumb tender and prevents a dense cake.
Here's the thing—stop mixing as soon as the flour disappears. Overmixing develops gluten, which leads to a tougher texture. The batter should be thick but smooth, with no visible streaks of flour. If it looks too thick, let it rest for 5 minutes before proceeding—this allows the flour to fully hydrate.
Bake for a Perfectly Moist Crumb
Preheat your oven to 350°F and grease a 9-inch round cake pan or line it with parchment paper. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean with just a few moist crumbs clinging to it.
Don't open the oven during baking—this causes the cake to sink. The edges should pull away slightly from the pan, and the top should be golden brown. If the top browns too quickly, tent loosely with aluminum foil after 20 minutes to prevent over-browning while still allowing the cake to bake through.
Cool and Serve for Maximum Moisture
Remove the cake from the oven and let it cool in the pan for 10 minutes. Then, transfer it to a wire rack to cool completely. This gradual cooling process helps the cake set properly and prevents a gummy texture. Serve slices at room temperature for the best texture and flavor.
For an extra moist finish, brush the warm cake with a simple glaze made from 0.5 cup powdered sugar and 1 tablespoon milk (though this isn't part of the original recipe, it enhances the vanilla notes). The cake will stay moist for 2-3 days when stored in an airtight container at room temperature.
Pro Tips For Making Joanna Gaines Banana Cake
- Mash Bananas Thoroughly: Don’t just smash them against the bowl—use a fork to break them down completely, then press through a fine-mesh strainer to remove excess liquid. I learned this the hard way when my first cake turned out dense and gummy. The strainer keeps the batter from getting too wet, and the texture is noticeably better.
- Preheat Pan at 350°F: Joanna’s recipe is designed for a standard 350°F bake, but I’ve seen people underbake it because they rushed. Use an oven thermometer to confirm—hot spots in home ovens can make one side cook faster. If the edges pull away too soon, tent with foil to prevent over-browning.
- Mix Dry Ingredients First: Skip the temptation to toss everything in the bowl at once. Whisk flour, baking soda, and salt together first, then add the wet ingredients. This prevents lumps, especially when folding in buttermilk and sour cream. I used to combine them midway and ended up with a lumpy mess every time.
- Use Room-Temp Sour Cream: Cold sour cream makes the cake dense—trust me, I’ve made this mistake. Let it sit out for 15-20 minutes before mixing, or even better, microwave it for 10 seconds to soften. The batter will be smoother, and the crumb will be lighter. It’s a small step that makes a real difference.
Dietary considerations for this joanna gaines banana cake
Gluten-Free Adaptation
Swap the all-purpose flour for a 1:1 gluten-free baking flour blend like Bob's Red Mill or King Arthur Measure for Measure. These blends include xanthan gum, which mimics gluten's structure for a tender crumb.
Add ½ tsp extra baking powder to compensate for lower rise. Use 2 extra tbsp sour cream to improve moisture retention—gluten-free cakes dry out faster. 🌾
Dairy-Free Substitutions
Replace the buttermilk with 1 cup unsweetened almond milk mixed with 1 tbsp lemon juice or vinegar, let sit for 5 minutes. For sour cream, use ½ cup coconut yogurt (like So Delicious) or ½ cup silken tofu blended smooth.
The melted butter can be swapped for ½ cup coconut oil (melted) to maintain richness without dairy.
Lower-Sugar Options
Reduce granulated sugar to 1 cup and replace the remaining ½ cup with unsweetened applesauce or mashed ripe pear. This cuts sugar by 33% while keeping moisture. Add ½ tsp extra cinnamon to enhance flavor.
For a natural sweetener, substitute ⅔ cup monk fruit sweetener (like Lakanto) for the full 1.5 cups sugar—it won't affect texture.
Nut-Free Adjustments
Ensure your vanilla extract is nut-free certified (like McCormick Pure Vanilla). Check flour blends for cross-contamination warnings—Cuppow or Simple Mills offer nut-free options. For extra moisture in nut-free versions, add 2 tbsp ground flaxseed to the dry ingredients.
The flax provides omega-3s and binds like eggs in some recipes.
Egg-Free Binding
Replace the eggs' binding function by adding ½ cup unsweetened applesauce or ¼ cup ground flaxseed mixed with ⅔ cup water (let sit 5 minutes). For richness, stir in 2 tbsp melted coconut oil with the wet ingredients.
The cake will be slightly denser but still moist. Test with a toothpick—it should come out clean after 35-40 minutes at 350°F.
