Description

Marble Swirled Banana Bread is a fancy and unique take on regular banana bread! It’s really easy to make but so impressive to serve. The flavor combination of chocolate and banana is straight delicious and chocolate chips add a fudgy dimension to things. You’re gonna love it.


Ingredients

Scale

Wet Ingredients:

  • 34 peeled bananas* note
  • 1/3 cup melted butter or neutral flavored oil* note
  • 1 teaspoon vanilla extract

Dry Ingredients:

  • 1.5 cups all-purpose flour
  • 1/2 cup cane sugar (sub-white, brown, or coconut sugar)
  • 1 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt

For the Swirl Batter:

  • 2 tablespoons cocoa powder, sifted
  • 1/3 cup chocolate chips
  • optional 2 teaspoons of milk, to mix

Instructions

  1. Mix the wet ingredients. Add peeled bananas to a medium-sized mixing bowl and mash very well. Add vanilla extract and melted butter and mix.
  2. Sprinkle dry ingredients across the top of the wet.  Mix until just combined. 
  3. Pour half of the batter into a separate bowl and to this bowl add the sifted cocoa powder and chocolate chips. If the batter is too thick, add 2-3 teaspoons of milk to make up for the cocoa powder addition.
  4. Line a loaf pan with parchment paper and pour the batter in, alternating the regular and chocolate batters.
    1. Insert a butter knife into a chocolate batter section and pull it through the batter over to the far side of the corresponding regular batter then lift and remove the knife. Repeat this with all chocolate/regular batter pairs.
  5. Bake in a pre-heated 350* oven for 55-65 minutes, until a toothpick inserted in the middle removes with only a few dry crumbs and no wet batter.
    1. If using a 9×5 loaf pan, the loaf will take less time to cook. Begin to check at the 45-minute mark.
    2. If using dark metal or glass pan, you may need to dial back the temp 25* as these pans tend to cook up the edges faster than the center.
    3. If using a large amount of bananas, the loaf will take longer to cook! Banana bread can take up to 70 minutes to complete cooking.
  6. Leave the loaf to cool in the pan for 15-20 minutes before removing and slicing for best results. The loaf will firm up a bit as it cools.

Notes

There are two very common loaf pan sizes: 8×4 and 9×5. The 9×5 pans create shorter, wider loaves that cook up a bit quicker. An 8×4 pan takes longer as it’s a taller loaf!

On Bananas: If using 4 large bananas, the loaf may take a bit longer to cook. If using smaller or fewer bananas, you may need to add a small splash of milk to help the batter come together appropriately. Splash meaning 1-2 teaspoons! The batter should be thick but not resistant to incorporating all dry spots of flour.

Oil vs Butter: Melted butter makes banana bread with a better flavor and texture. Using oil creates a very moist banana bread but it may have a gummier consistency.
