  • 100 grams (1/2 Cup) Granulated Sugar
  • 100 grams (1/2 Cup) Brown Sugar
  • 2 Large Eggs, at room temp.
  • 1 Teaspoon Pure Vanilla Extract
  • 6oz (3/4 Cup) Sour Cream/ Greek Yogurt
  • 12oz (3 Medium) Very Ripe Bananas, mashed (measured without peel)
  • 250 grams (2 Cups) All-Purpose Flour/ Plain Flour
  • 1 Teaspoon Baking Soda
  • 1/2 Teaspoon Salt
  • 1/2 Teaspoon Ground Cinnamon
  • 1/2 cup Walnuts, roughly chopped ( I prefer to use roasted but raw are fine too)

Cinnamon Swirl

  • 4 Tablespoons Butter, melted
  • 6 Tablespoons Dark Brown Sugar
  • 3 Tablespoons Ground Cinnamon
  • 2 Tablespoons Brown Sugar (Optional Topping)


  1. Preheat oven to 350F/180C and grease a 9X5 loaf pan.
  2. In a large bowl mix together the butter and sugars, until light and fluffy. Then add eggs and vanilla extract.
  3. Add bananas and sour cream, mix to evenly combine. Gently fold in the flour, baking soda, salt, and ground cinnamon, when almost fully combined fold in the nuts.
  4. In a small bowl whisk together the melted butter, brown sugar, and ground cinnamon until fully combined.
  5. Pour 1/3 of banana bread batter into prepared pan then drop teaspoon size dollops of cinnamon mixture on top, use a butter knife to swirl it in, I don't swirl too much I like the bigger cinnamon swirls. Repeat two more times ending with cinnamon swirls on top, if desired sprinkle brown sugar on top.
  6. Bake for 50-60 minutes. or until a toothpick inserted comes out clean. Let cool at least 30 minutes before removing from pan. Let cool on a wire rack. Store at room temperature unless you live in a warm climate store in the fridge.
