How to Make Sweet Potato Banana Bread: An Incredible Ultimate Recipe

Ingredients

• 1 cup mashed sweet potatoes (about 1 medium sweet potato; cooked and mashed)
• 1 cup mashed ripe bananas (about 2–3 medium bananas)
• 1/2 cup granulated sugar
• 1/2 cup brown sugar, packed
• 1/2 cup vegetable oil or melted coconut oil
• 3 large eggs
• 1 teaspoon vanilla extract
• 2 cups all-purpose flour (about 240 g)
• 1 teaspoon baking soda
• 1 teaspoon baking powder
• 1/2 teaspoon salt
• 1 teaspoon ground cinnamon
• 1/2 teaspoon nutmeg (optional)
• 1/2 cup chopped nuts (walnuts or pecans, optional)

Optional ingredients & substitutions:

• Replace vegetable oil with an equal amount of melted butter for richer flavor.
• Use applesauce (1:1) to reduce oil; note the crumb will be slightly denser.
• For a gluten-free loaf: substitute a 1:1 gluten-free flour blend (see tips below).
• Swap brown sugar for coconut sugar for a nuttier profile.
• Add 1/2 cup dark chocolate chips or 1/2 cup raisins for variation.

Before you begin: For smooth sweet potato mash, roast or bake whole sweet potatoes until fully tender; scoop and mash. If you want gluten-free baking tips, consult this gluten-free baking resource for helpful conversions and texture advice.

Step-by-step instructions

1. Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan and line it with parchment if you prefer easier removal.
2. In a large bowl, whisk together mashed sweet potatoes, mashed bananas, granulated sugar, brown sugar, and oil until combined.
3. Beat in the eggs one at a time, then stir in the vanilla extract.
4. In a separate bowl, sift (or whisk) the flour, baking soda, baking powder, salt, cinnamon, and nutmeg.
5. Gently fold the dry ingredients into the wet mixture until just combined. Do not overmix—stop when you no longer see streaks of flour.
6. Fold in the chopped nuts or chocolate chips if using.
7. Pour batter into the prepared loaf pan and smooth the top. Optionally sprinkle a few extra nuts or a light dusting of cinnamon sugar on top.
8. Bake 55–65 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (not wet batter). If the top browns too quickly, tent loosely with foil after about 35–40 minutes.
9. Let the loaf cool in the pan for 10–15 minutes, then transfer to a wire rack to cool completely before slicing.

Practical tips:

• Avoid overmixing to keep a tender, light crumb.
• Use ripe bananas with brown speckles for the best flavor and sweetness.
• Tap the pan lightly on the counter to remove air pockets before baking.
• If using coconut oil, ensure mashed ingredients are not hot or the oil may solidify and clump.

Best Pairings

• Plain or gently toasted with a smear of butter or cream cheese.
• Warm slices alongside strong coffee, chai tea, or a latte—cinnamon notes pair beautifully with spiced drinks.
• Serve slightly warmed with a dollop of Greek yogurt and a drizzle of maple syrup for brunch.
• Make mini sandwiches with nut butter for an energy-packed snack.
• Crumble into yogurt or oatmeal for a deconstructed dessert.

Shelf Life & Storage

• Room temperature: Store in an airtight container or wrapped tightly for up to 2 days.
• Refrigeration: Keep in an airtight container for 4–7 days; bring to room temperature or warm slices gently before serving.
• Freezer: Double-wrap in plastic wrap and foil or place in a freezer-safe bag; stores well for up to 3 months. Thaw overnight in the refrigerator or at room temperature for a few hours.

How to thaw: For single slices, microwave 12–20 seconds or toast gently until warm.

Chef’s Advice

• Texture key: The balance between banana and sweet potato matters. If the loaf feels too dense, reduce one of the wet ingredients slightly (e.g., use 2 eggs instead of 3) or increase baking powder by 1/4 tsp.
• Spice pairing: Complement cinnamon with a pinch of allspice or cardamom for an autumnal lift.
• Testing doneness: Use a thin skewer; it should have moist crumbs attached but not runny batter. If the center is underbaked but the top is browned, lower the oven to 325°F (160°C) and continue baking.
• Nuts: Toast them briefly before folding in to amplify flavor and crunch.
• Pan choice: A metal loaf pan conducts heat better for browning; glass pans may require a few extra minutes.

Creative Twists

• Vegan version: Replace eggs with 3/4 cup applesauce or three flax eggs (3 tbsp ground flax + 9 tbsp water), and use coconut oil or another plant oil. Swap dairy if included in toppings.
• Gluten-free: Use a 1:1 gluten-free flour blend that contains xanthan gum; reduce mixing and add an extra egg or 1–2 tablespoons of milk for moisture if needed.
• Spiced maple walnut: Replace brown sugar with 1/3 cup maple syrup (reduce oil by 1–2 tbsp), add 1 tsp ground ginger, and fold in toasted walnuts.
• Chocolate-hazelnut swirl: Swirl a mixture of melted chocolate and a spoonful of hazelnut butter into the batter before baking for a marbled finish.

All Your Questions Answered
Q: Can I use canned sweet potato puree?
A: Yes—use drained puree and measure 1 cup. If the puree is very watery, drain or reduce other liquids slightly.

Q: My bread is gummy in the center—what went wrong?
A: Likely underbaked or over-moistened. Bake longer and check with a skewer; slightly reduce wet ingredients next time or add an extra 1/4 cup flour.

Q: How do I make this less sweet?
A: Reduce granulated and/or brown sugar by up to 1/4 cup total. Rely on ripe bananas and sweet potato for natural sweetness.

Q: Can I halve the recipe?
A: Yes. Bake in a smaller loaf pan (8×4) and begin checking doneness around 40–50 minutes.

Q: Is this freezer-friendly?
A: Absolutely—wrap well and freeze up to 3 months. Thaw in the fridge overnight.
