How to Make Peanut Butter Banana Bread

  1. In a mixing bowl, mash the bananas. 
  2. Add the creamy peanut butter, vegetable oil, brown sugar and vanilla extract, blend with an electric mixer on low. 
  3. Add the eggs, beat gently just until the egg yolks break.
  4. In a small bowl combine the flour, baking soda, cinnamon and salt. Gently fold the dry ingredients into the banana mixture, just until combined.
  5. Spray a loaf pan (either 9×5 or 8.5×4.5) with non-stick cooking spray. Pour the batter into the pan.
  6. Bake for 45 minutes, place aluminum foil over the bread and bake for 20-25 additional minutes or until a toothpick inserted in the center comes out clean. 

How to Quickly Ripen Bananas in the Oven

Spotty, over ripe bananas make the best peanut butter banana bread! If your bananas aren’t over ripe, you can fix that! Place the bananas on a foil lined baking sheet in a 300ºF oven for 30-40 minutes, until the peels become black and shiny.

How to Make this Bread Gluten Free

I’ve made this bread with both regular and gluten free flour with awesome results on multiple occasions. I recommend King Arthur’s Gluten Free Measure for Measure Flour. Use it as a one for one substitute for regular flour.

How to Store

Store the bread in an airtight container on the counter. To keep the bread extra moist, wrap in plastic wrap then place inside the container. 

How to Freeze Quick Bread

To freeze the whole loaf: allow it to cool completely, then wrap well in plastic wrap, then in aluminum foil. Place inside a ziplock bag. To thaw, place the wrapped bread in the fridge overnight.

To freeze individual slices: allow the loaf to cool completely and slice. Wrap each slice in plastic wrap then in aluminum and place inside a ziplock bag. To thaw, place a slice in the fridge overnight. Or unwrap and microwave for 30 second intervals.

Tips

Do not over mix the batter.

I have been guilty of this myself and I am learning to be okay with lumps in my batter. For quick bread, do not use your electric mixer to beat in the dry ingredients, using a spatula and mixing by hand will give you more control. “Mix just until incorporated” means mixing the dry ingredients with the wet ingredients until you can just no longer see any flour streaks. Yes you should still scrap the sides and the bottom of the bowl, but do that as you’re mixing in the flour.

Do not over bake the bread. 

Sometimes the bread can trick you, it can look done on the outside but still be doughy in the middle. That’s when tenting the bread with aluminum foil comes in handy. It protects the top from becoming too brown, overcooked or crusty. 

Loaf pan size matters.

There’s two popular loaf pan sizes – 9×5 and 8.5×4.5. Even though the numbers are similar, the pans actually differ in size by 15%. The 8.5×4.5 pan will yield a tall, more domed bread and will take 5-10 minutes longer when baking. The total suggested bake time for a 8.5×4.5 inch pan is 65-70 minutes and 9×5 inch pan is 60-65 minutes.
