7 thoughts on “Sourdough Discard Banana Bread”
This recipe makes such a wonderful bread! For me it is the right balance between bready and cakey, mine turned out a little more on the bready side which I prefer. Also it isn’t too sweet
I used two overripe bananas and otherwise followed the recipe.
The only thing I would suggest is to list the ingredients in the order they are used in the recipe, as it would make it easier to follow. But the recipe itself is spot on and could become my regular banana bread recipe from now on! (Plus a great way to use discard)
In stead of making this into a loaf I chose to do muffins! I got 19 out of this batch using a 1/4 scoop. I baked them for 15 minutes! Very delicious! Definitely going to add mini chocolate chips next time!
Made it and my husband loved it! 🥰 I used 3 really overriped bananas. Didn’t make any changes to the recipe. Will make it again!
This was an awesome banana bread and I love using the discards. It looked just like the picture. Taste was terrific.
By far the best banana bread with discard! Yum
This recipe was perfect, it tasted absolutely delish 🙂
Made it today and it was delicious
