Snickerdoodle Banana Bread
This snickerdoodle banana bread combines the warm cinnamon-sugar flavor of snickerdoodle cookies with the moist, tender comfort of classic banana bread. Extra-ripe bananas and sour cream create a pillowy crumb that stays soft for days, while a buttery cinnamon-sugar topping bakes into a delicate, crispy crust that makes every slice irresistible.
Equipment
- 9x5-inch loaf pan - Standard metal pan for even browning
- Large mixing bowl
- Medium mixing bowl - For dry ingredients
- Small bowl - For the cinnamon-sugar topping
- Fork or potato masher - For mashing bananas
- Whisk
- Rubber spatula
- Measuring cups and spoons
- Cooling rack
- Aluminum foil - To tent bread if top browns too quickly (optional)
- Parchment paper - For easy loaf removal (optional)
Ingredients
For the Banana Bread
- 3 large overripe bananas - mashed, about 1½ cups or 340g — the more brown spots, the better
- ⅓ cup unsalted butter - 75g, melted and slightly cooled
- ¾ cup granulated sugar - 150g
- 1 large egg - beaten, room temperature
- 1 tsp pure vanilla extract
- ½ cup sour cream - 120g, room temperature; substitute equal amount of Greek yogurt
- 1½ cups all-purpose flour - 190g; or use a 1:1 gluten-free flour blend
- 1 tsp baking soda
- ½ tsp salt
- 1 tsp ground cinnamon
For the Snickerdoodle Topping
- 3 tbsp granulated sugar - 38g
- 1½ tsp ground cinnamon
- 1 tbsp unsalted butter - 14g, melted
Instructions
- Preheat oven to 350°F (175°C) with rack in center position. Grease a 9x5-inch loaf pan with butter or non-stick spray, dust with flour, and tap out excess (or line with parchment paper).
- Peel the overripe bananas into a large mixing bowl and mash with a fork or potato masher until mostly smooth with a few small lumps. Measure out 1½ cups (340g).
- Stir melted butter into mashed bananas, then mix in sugar, beaten egg, and vanilla extract until smooth. Fold in sour cream until fully incorporated with no streaks.
- In a separate medium bowl, whisk together flour, baking soda, salt, and cinnamon until evenly distributed with no clumps of baking soda.
- Add dry ingredients to wet ingredients all at once and fold with a rubber spatula using broad sweeping motions just until no dry flour remains — do not overmix. The batter will be thick and slightly lumpy.
- In a small bowl, stir together 3 tablespoons sugar and 1½ teaspoons cinnamon, then mix in 1 tablespoon melted butter until the mixture is crumbly and sandy.
- Pour batter into prepared loaf pan and spread evenly; tap pan on counter a few times to release air bubbles. Sprinkle cinnamon-sugar topping evenly over the entire surface, including edges.
- Bake for 60–65 minutes until a toothpick inserted in the center comes out clean or with just a few moist crumbs. If the top browns too quickly after 45 minutes, tent loosely with aluminum foil.
- Place the pan on a cooling rack and let cool for 15 minutes, then run a knife around the edges and turn out the loaf. Cool at least 30 minutes before slicing for clean cuts.
Notes
- Use very ripe bananas: The more brown spots, the better — overripe bananas provide natural sweetness and moisture that underripe ones can't match.
- Don't overmix: Stir just until the flour disappears; overmixing develops gluten and results in tough, dense bread.
- Room temperature ingredients: Let the egg and sour cream sit at room temperature for 30 minutes before mixing for a smoother batter.
- Test for doneness properly: Insert a toothpick into the very center of the loaf — not just the edges — as the center takes the longest to bake.
- Sour cream substitute: Use an equal amount of full-fat Greek yogurt; the texture will be nearly identical with a slightly tangier flavor.
- Storage: Wrap cooled bread tightly in plastic wrap and store at room temperature for up to 3 days, or refrigerate for up to 1 week.
- Freezing: Wrap the whole cooled loaf (or individual slices) in plastic wrap then foil and freeze for up to 3 months. Thaw at room temperature for 2–3 hours.
- Make it your own: Fold in 1 cup of chocolate chips, or ½ cup chopped walnuts or pecans, before adding batter to the pan.
- Gluten-free option: Substitute a 1:1 gluten-free baking flour blend for the all-purpose flour; handle the cooled loaf gently as the texture will be slightly more delicate.
- Tastes better the next day: The flavors meld and deepen overnight, making this an ideal make-ahead treat.
