Step by step instructions
Here is how to make and bake this One Banana Banana Bread. You will need an 8x4 loaf pan lined with parchment paper, 3 mixing bowls, a spatula, and an electric hand-held mixer.
Step 1 – Prep. Line your loaf pan down and up 2 sides with parchment paper and then grease the sides that aren't lined. If you need a recommendation, this is my favourite loaf pan Mash the bananas and set aside.
Step 2 - Cream butter, oil, and sugar. In a large bowl, add the butter, oil, and white sugar. Mix on medium speed for 2-3 minutes until well combined.
Step 3 - Add in egg. Add the egg and continue mixing, making sure to scrape the sides of the bowl when needed. Mix for another 1-2 minutes.
Step 4 - Add in bananas, sour cream, and vanilla. Mix in the rest of your wet ingredients in. It's ok if it curdles.
Step 5 - Add in dry ingredients. Slowly add the dry ingredients in two additions, mixing until just combined between each addition. I used a spatula for this part.
Step 6 - Transfer. Add the batter into the prepared pan and spread evenly.
Step 7 - Bake. Bake the banana bread for 35-45 minutes or until a toothpick inserted comes out clean. Mine took 40 minutes exactly.
Allow the banana bread to cool, then slice and enjoy!
This banana bread stays good on the counter for 3 days in an airtight container and in the refrigerator for up to 1 week!
Expert Baking Tips
