Ingredients List
Here’s a closer look at each of the four core ingredients and why they matter:
3 medium to large ripe bananas
Must be heavily spotted or nearly blackened—this ensures maximum sweetness and mashability. Bananas are the primary moisture source here.1½ cups all-purpose flour
You can also use whole wheat flour for more fiber, or a gluten-free blend if needed. The flour provides the structure for your loaf.1 teaspoon baking soda
The leavening agent that gives your banana bread lift. When combined with the acid in bananas, it reacts to create air bubbles.½ cup chopped walnuts (optional but recommended)
Adds protein, crunch, and heart-healthy fats. You can substitute with pecans or seeds if needed.
Step-by-Step Instructions
Step 1: Preheat the Oven
Set your oven to 350°F (175°C). Line a 9×5-inch loaf pan with parchment paper or lightly grease it with oil.
Parchment paper helps you easily lift out the loaf after baking without sticking.
Step 2: Mash the Bananas
In a large mixing bowl, mash the bananas thoroughly using a fork or potato masher. Aim for a mostly smooth consistency, though small chunks are fine—they add a rustic texture.
The riper the banana, the better. Bananas with nearly black peels produce the sweetest, most flavorful loaf.
Step 3: Add Dry Ingredients
Add the flour and baking soda directly into the bowl with the bananas. Gently fold with a spatula until the dry flour is just absorbed.
Avoid overmixing to keep your loaf tender. Overmixing develops gluten, which can make the bread dense.
Step 4: Fold in Walnuts
Add the chopped walnuts and gently fold them in. This adds both flavor and texture.
Step 5: Transfer to Pan and Smooth
Pour the batter into your prepared loaf pan. Use the spatula to spread it evenly and smooth the top.
Step 6: Bake
Place the pan in the preheated oven and bake for 45–55 minutes, or until a toothpick inserted in the center comes out clean.
Ovens vary. Start checking at the 45-minute mark. A slightly golden top and firm center are signs of doneness.
Step 7: Cool
Let the loaf cool in the pan for 10 minutes. Then carefully lift it out and transfer it to a wire rack to cool completely.
Cooling allows the banana flavor to deepen and helps the loaf firm up for easier slicing.

Tips and Substitutions
Want to customize or adjust based on your pantry? Here’s how:
Flour Substitutes
Whole wheat flour: Heavier, heartier loaf. Great for fiber.
Oat flour: Gluten-free option; use a little less as it absorbs more moisture.
Almond flour: Adds richness but may need flax or chia egg for binding.
Banana Swaps
If you’re short on bananas, substitute ½ cup of unsweetened applesauce or pumpkin purée per banana, though flavor will change.
Nut-Free Version
Use seeds like sunflower or pumpkin, or omit completely.
Boost Flavor Naturally
Add 1 teaspoon cinnamon
Add 1 teaspoon vanilla extract
Sprinkle coarse sugar or oats on top for texture
Recipe Variations
Once you’ve mastered the basic loaf, experiment with these easy variations:
1. Vegan Chocolate Chip Banana Bread
Add ½ cup dark vegan chocolate chips to the batter. Kid-approved and indulgent.
2. Tropical Twist
Fold in ¼ cup shredded coconut and ¼ cup chopped dried pineapple for a beachy flavor profile.
3. Cinnamon Swirl Banana Bread
Layer cinnamon-sugar mixture in the middle by pouring in half the batter, sprinkling cinnamon sugar, then topping with remaining batter.
4. Berry Banana Bread
Gently fold in ½ cup fresh or frozen blueberries for juicy bites throughout.
Each variation is just as easy—and many more are found in the Plant-Based Cookbook – 200 Vegan Recipes. Let your kitchen become your creative studio.

Common Questions (FAQ)
Can I use baking powder instead of baking soda?
Baking soda is preferred because it reacts with the acidity in bananas to create lift. If using baking powder, use 2 teaspoons, but expect a slightly different texture.
How do I know when banana bread is done?
Insert a toothpick in the center—it should come out clean or with a few crumbs, not wet batter. The top should be golden and firm to the touch.
Why is my banana bread dense?
Overmixing, not using enough bananas, or using cold ingredients can cause density. Follow the steps gently and let the bananas shine.
Can I double the recipe?
Yes, but use two loaf pans. Doubling the batter in one pan can result in uneven baking.
