  • Rich in healthy fats and fiber from walnuts

  • Easily customizable—add spices, seeds, or even chocolate chips

  • Suitable for both beginner and experienced bakers

Ingredients Needed

Here’s a list of simple pantry ingredients to make a classic banana walnut cake. This makes one 8-inch loaf or round cake:

  • 3 medium overripe bananas (mashed)

  • 1/2 cup neutral oil (or melted butter)

  • 3/4 cup brown sugar (adjust as per taste)

  • 2 eggs (or flax eggs for eggless version)

  • 1 and 1/2 cups all-purpose flour (or whole wheat flour for a healthier version)

  • 1 tsp baking soda

  • 1/2 tsp baking powder

  • 1/2 tsp cinnamon powder (optional)

  • 1/4 tsp salt

  • 1 tsp vanilla extract

  • 1/2 cup chopped walnuts (toasted for extra flavor)

  • 2 tbsp milk (only if needed to loosen batter)

Step-by-Step Recipe of Banana Walnut Cake

Step 1: Preheat and Prepare

Preheat your oven to 175°C (350°F). Grease a loaf tin or cake pan and line it with parchment paper.

Step 2: Mash the Bananas

Peel and mash the ripe bananas in a large mixing bowl using a fork until smooth but slightly chunky. This will give texture to your cake.

Step 3: Add Wet Ingredients

To the mashed bananas, add oil (or melted butter), sugar, eggs, and vanilla extract. Mix until well combined. You can use a hand whisk or an electric mixer.

Step 4: Combine Dry Ingredients

In a separate bowl, sift together the flour, baking soda, baking powder, cinnamon (if using), and salt. Mix gently.

Step 5: Fold Everything Together

Add the dry ingredients to the wet mixture in batches. Gently fold using a spatula until you get a thick but pourable batter. Add a splash of milk if it’s too dry. Fold in chopped walnuts at the end.

Step 6: Pour and Bake

Pour the batter into the prepared pan. Tap it gently to release air bubbles. Optionally, sprinkle some extra walnuts on top.

Bake for 35–45 minutes, or until a skewer inserted in the center comes out clean. Baking times may vary slightly based on oven and pan size.

Step 7: Cool and Serve

Let the cake cool in the pan for 10 minutes, then transfer to a wire rack. Slice and serve warm or at room temperature. It tastes even better the next day.

Eggless and Vegan Alternatives

For an eggless version, replace each egg with:

  • 1 tbsp flaxseed powder + 3 tbsp water (rested for 10 minutes)

  • Or 1/4 cup plain yogurt or mashed banana

To make it fully vegan:

  • Use plant-based milk like almond or soy

  • Use oil or vegan butter

  • Use coconut sugar or maple syrup as sweeteners

Tips for the Best Banana Walnut Cake

  • Always use overripe bananas with black spots for maximum flavor and natural sweetness

  • Toast the walnuts lightly before folding them in—it enhances their nuttiness

  • Do not overmix the batter once flour is added; this keeps the cake tender

  • If you prefer a lighter cake, use half all-purpose and half whole wheat flour

  • For added texture, you can add seeds like sunflower or flax, or dark chocolate chips

  • The cake stores well for 2–3 days at room temperature and up to a week in the fridge

How to Serve Banana Walnut Cake

  • As a tea-time snack with a hot cup of chai or coffee

  • Warmed slightly and topped with peanut butter or honey for breakfast

  • Sliced and served with ice cream or whipped cream for a dessert upgrade

  • Used as a base for a layered trifle with custard and fruits

  • Packed in tiffin boxes as a healthy snack for kids and adults alike

Storage and Shelf Life

  • Store in an airtight container at room temperature for 2–3 days

  • Refrigerate for up to 7 days—warm before serving for best taste

  • Freeze slices wrapped in cling film for up to 1 month—thaw before use
