Tell me about this recipe
- This loaf cake is made using the creaming method. Butter and sugar is whipped together until light and airy, before adding dry ingredients and sour cream in three additions
- Sour cream is used to give lots of moisture in this loaf.
- It's covered in a walnut and cinnamon crunch topping, but you can make it without if you want the loaf to be plain.
The printable recipe card with the full list of ingredients and instructions can be found at the bottom of this post
- Walnuts: I added chopped walnuts to my cinnamon topping, however you can substitute them for a different nut or leave the nuts out all together.
- Spices: the loaf is spiced with cinnamon and nutmeg, while the topping has cinnamon and ginger. Switch up the spices though if you want to!
- Sour Cream: the sour cream makes the banana bread super moist! You can substitute it for full fat yoghurt if you don't have sour cream.
How to make this recipe
One: Mix together all of the streusel ingredients together, then place in the fridge while you make the loaf.
Two: In a medium bowl, whisk together the flour, baking soda, spices and salt.
Three: In a stand mixer fitted with the paddle attachment, cream the butter until smooth.
Four: Add the light brown sugar and granulated sugar and mix for 3 minutes on medium speeed.
Five: Add in your egg and vanilla and beat again on medium speed for 1 minute.
Six: Turn the speed to low and add in your mashed bananas. The batter might be lumpy which is fine!
Seven: Add the dry ingredients in three additions, alternating with the sour cream. Make sure you start and end with the dry ingredients. Scrape down the side of the bowl after each addition.
Eight: Preheat your oven to 350 degrees. Pour the batter into a greased and lined 8.5x4.5 inch loaf pan. Tap on your counter to get rid of any air bubbles.
Nine: Sprinkle over your topping. Bake for 50-60 minutes. A toothpick inserted will come out with a few crumbs.
Ten: Let the loaf cool for 20 minutes before removing it and putting it on a cooling rack.
- I highly recommend using a weighing scale and measuring out your ingredients the metric way. It makes a huge difference to your baking and is the most accurate way to bake!
- I make sure that all of my ingredients are at room temperature before I start the recipe, so pull out all of the ingredients (including the sour cream!) before you start baking.
- Use a light metal pan for this recipe. A dark metal will scorch the sides of the loaf.
- Mash your bananas using a fork or potato masher
Frequently Asked Questions
I promise you this cake is worth the wait! BUT if you really need to get things going, make sure your bananas are in a warm area in a paper bag for a day or two. I have seen ‘hacks’ for cooking your bananas to make them ripen faster but this won’t give you the same banana taste!
Swap out the sour cream for full-fat yoghurt or greek yoghurt, swap in chopped pecans for the walnuts and mix up the spices or leave them out entirely.
Wrap up your banana bread in plastic wrap and store at room temperature for up to 2 days. To freeze, wrap up each slice in foil or plastic wrap and freeze for up to 3 months. Defrost overnight in the fridge.
I'm using a 8.5x4.5 inch loaf pan. If you use a 9x5, while that doesn't seem like a huge difference, will make your loaf a lot flatter and won't need as much time in the oven.
