Sour Cream Banana Bread

I know I know, ANOTHER banana bread recipe? But hear us out – there are two things that make this banana bread recipe different, more moist, more flavorful. Alright, we gave away the first secret ingredient in the title, the sour cream adds a wonderful moistness to the bread without a strong tang that yoghurt can if you’ve seen those recipes. The second ingredient is our homemade chai spice blend that you can also find on our blog – while all banana breads have some sort of spice be it cinnamon or nutmeg, we STRONGLY feel that our spice blend has the perfect warmth for baking – its great in a cup of Indian chai as well! There – you know our secret now! The rest of the ingredients are pretty standard, we make several loaves of this every Christmas as part of our holiday baking – read on for some of our tips and modifications. 

Tips & Tricks

  • You can easily use frozen bananas if you’re like us and keep racking up bananas past their prime – just make sure you mix half frozen half fresh to avoid an overly “wet” bread since the frozen bananas tend to retain more moisture.
  • You can substitute brown sugar for equal parts maple syrup but it will be a sweeter cake – Sneha is Canadian so there is always maple syrup in the mix.
  • Its important not to over mix your batter or you will end up with a dry bread – to avoid this, we prefer adding our mix ins with the wet ingredients and then add dry ingredients.
  • You can bake these in loaf pans or as muffins – same batter works for both! 
  • These freeze REALLY well, once completely cool wrap in plastic wrap and store in a ziplock for up to 4 months; once ready, defrost in fridge overnight and you’re in business.
