Snickerdoodle Banana Bread (Printable)

Moist banana bread with a cinnamon-sugar swirl, inspired by classic snickerdoodle cookies.

# What You'll Need:

→ Dry Ingredients

01 - 2 cups all-purpose flour
02 - 1 teaspoon baking soda
03 - 1/2 teaspoon baking powder
04 - 1/2 teaspoon salt
05 - 1 1/2 teaspoons ground cinnamon

→ Wet Ingredients

06 - 3 ripe bananas, mashed (about 1 1/4 cups)
07 - 1/2 cup unsalted butter, melted and cooled
08 - 3/4 cup granulated sugar
09 - 1/4 cup brown sugar
10 - 2 large eggs
11 - 1 teaspoon pure vanilla extract

→ Cinnamon-Sugar Swirl and Topping

12 - 1/4 cup granulated sugar
13 - 1 tablespoon ground cinnamon

# Step-by-step:

01 - Preheat oven to 350°F. Grease and flour a 9x5-inch loaf pan.
02 - In a medium bowl, whisk together the flour, baking soda, baking powder, salt, and 1 1/2 teaspoons cinnamon until evenly distributed.
03 - In a large bowl, combine the mashed bananas, melted butter, granulated sugar, brown sugar, eggs, and vanilla. Beat until smooth and well incorporated.
04 - Add the dry ingredients to the wet mixture and fold gently until just combined. Avoid overmixing to keep the texture tender.
05 - In a small bowl, stir together 1/4 cup granulated sugar and 1 tablespoon ground cinnamon.
06 - Pour half the batter into the prepared loaf pan and spread evenly. Sprinkle half of the cinnamon-sugar mixture over the surface.
07 - Add the remaining batter and smooth the top. Sprinkle the remaining cinnamon-sugar over the surface. Draw a butter knife gently through the layers to create a marbled effect.
08 - Bake for 50 to 60 minutes, until a toothpick inserted into the center comes out clean.
09 - Let cool in the pan for at least 15 minutes, then turn out onto a wire rack to cool completely before slicing.

# Expert Advice:

01 -
  • The cinnamon sugar ribbon running through the middle turns ordinary banana bread into something you cannot stop eating
  • It comes together in one bowl with zero fancy technique but tastes like it came from a bakery
02 -
  • The cinnamon sugar layer can sink if your batter is too thin so make sure your bananas are mashed not pureed into soup
  • Checking the bread early at 45 minutes with a toothpick is better than discovering a burnt top at 60 minutes since ovens vary wildly
03 -
  • Let the melted butter cool for at least 10 minutes before adding it to the eggs or you will end up with scrambled egg pieces in your batter
  • The toothpick test is not reliable if you hit a cinnamon sugar pocket so test in two different spots near the center
