Snickerdoodle Banana Bread (Moist + Cinnamon Sugar Swirl, Crunchy Cinnamon Crust)
This Snickerdoodle Banana Bread is classic banana bread with a snickerdoodle-style upgrade: warm cinnamon spice, a thick cinnamon-sugar swirl, and a cinnamon-sugar coated pan that bakes into a lightly crunchy, sweet crust. It’s fluffy, moist, and totally fall-worthy but honestly perfect any time you’ve got ripe bananas.

Why You’ll Love It
- Moist and fluffy (Greek yogurt + ripe bananas = perfect crumb)
- Cinnamon sugar swirl in every slice
- Cinnamon-sugar “crust” around the loaf (the best part!)
- Simple pantry ingredients, no fancy steps
Ingredients
For the Loaf
- Butter, for greasing the loaf pan
- 1 1/4 cups sugar, divided (golden sugar or regular granulated sugar)
- 2 tsp ground cinnamon
- 3 very ripe bananas, mashed
- 1/2 cup butter, melted and cooled slightly
- 2 eggs, room temperature
- 1/2 cup Greek yogurt (full-fat or non-fat)
- 2 tsp vanilla extract
- 2 cups all-purpose flour
- 1 tsp baking soda
- 1/2 tsp salt
Step-by-Step Instructions
- Preheat oven to 350°F (175°C). Grease a loaf pan with butter.
- Make cinnamon sugar: Mix 1/2 cup sugar + 2 tsp cinnamon.
- Coat the pan: Sprinkle a few tablespoons of cinnamon sugar inside the pan (bottom + sides). Set aside.
- Mix wet ingredients: In a large bowl, whisk bananas + melted butter. Whisk in remaining 3/4 cup sugar, eggs, Greek yogurt, and vanilla.
- Mix dry ingredients: In another bowl, combine flour, baking soda, and salt.
- Combine: Fold dry into wet just until combined (don’t overmix).
- Layer + swirl:
- Pour half the batter into the pan
- Sprinkle half of the remaining cinnamon sugar
- Add the rest of the batter
- Sprinkle the remaining cinnamon sugar on top
(Optional: use a knife to make 2–3 gentle swirls for more defined ribbons.)
- Bake about 60 minutes, until a knife/toothpick inserted in the center comes out clean.
- Cool 15 minutes, then remove from pan and cool before slicing.
Pro Tips for a Perfect Swirl + Texture
- Use super ripe bananas (soft + brown-speckled) for maximum sweetness and moisture.
- Don’t over-swirl or the cinnamon sugar will disappear into the batter.
- If the top browns early, tent with foil around the 40–45 minute mark.
- Let it cool before slicing—warm banana bread can seem underbaked until it sets.
