Substitute for Brown Sugar in Banana Bread

For banana bread, replace each 1/2 cup (about 100 g) of packed brown sugar with 1/2 cup (100 g) granulated sugar and 1 tablespoon (20 g) molasses. The molasses restores brown sugar’s caramel-like flavor and moisture, while ripe bananas keep this one-loaf version tender and sweet.

Ingredients

1 1/2 cups (190 g) all-purpose flour, measured by spooning it into the cup and leveling the top
1 teaspoon (5 g) baking soda
1/4 teaspoon (1.5 g) fine salt
1/2 teaspoon (1 g) ground cinnamon, optional
3 very ripe medium bananas, mashed to make about 1 1/2 cups (345 g)
1/2 cup (113 g) unsalted butter, melted and cooled slightly
1/2 cup (100 g) granulated sugar
1 tablespoon (20 g) unsulfured molasses, preferably light or regular rather than blackstrap
1 large egg (about 50 g without shell), at room temperature if convenient
1 teaspoon (5 ml) vanilla extract

Instructions

Heat the oven to 350°F (175°C). Grease an 8 1/2-by-4 1/2-inch (about 21-by-11-cm) loaf pan, or line it with parchment paper with a little overhang so you can lift out the baked loaf. Set the pan aside while you mix the batter.
In a medium bowl, whisk together the flour, baking soda, salt, and cinnamon, if using. Breaking up any small lumps now helps distribute the baking soda evenly, so the loaf rises consistently instead of developing bitter or overly browned patches.
In a large bowl, mash the bananas with a fork until mostly smooth but still slightly textured. Whisk in the melted butter, granulated sugar, molasses, egg, and vanilla until combined. The molasses may leave a few darker streaks at first; keep stirring until the mixture looks evenly brown.
Add the flour mixture to the banana mixture. Fold gently with a spatula just until no large dry pockets remain. A few small flour streaks are preferable to overmixing: too much stirring develops gluten and can make banana bread tough or give it a peaked, chewy middle.
Scrape the batter into the prepared pan and level the top. Bake on the center rack for about 60 minutes, beginning to check at 55 minutes. The top should be browned and a toothpick inserted near the center should come out with a few moist crumbs, not wet batter. If the top is darkening before the center is done, loosely cover it with foil for the remaining bake.
For the egg-containing loaf, use a food thermometer to confirm the center reaches 160°F (71°C), the USDA FSIS safe minimum for egg dishes; banana bread is generally fully baked at about 200–205°F (93–96°C), which also helps set its crumb. Remove the pan from the oven and let it stand for 15 minutes. Lift the loaf out or turn it onto a rack, then cool for another 45 minutes before slicing. This one-hour cooling period helps the center finish setting and prevents gummy slices.

Tips

Choose bananas with plenty of brown spots and a strong banana aroma. Green or just-yellow fruit is firmer and less sweet, so the bread may taste less ripe and the bananas will be harder to mash. Weigh the mashed fruit if possible; too much banana can leave the center damp even when the outside looks done.
Use ordinary unsulfured molasses for the closest brown-sugar flavor. Blackstrap molasses is much more bitter and assertive, so it can overpower the banana. If it is all you have, use 2 teaspoons (about 13 g) blackstrap and add 1 teaspoon (5 ml) milk or water to the wet mixture.
Measure flour lightly rather than scooping straight from the bag. A packed cup can add enough extra flour to make a dry, heavy loaf. If you do not have a scale, fluff the flour, spoon it into the measuring cup, and level it without tapping the cup.
Do not slice the loaf while it is hot. The middle is still setting as it cools, and an early cut can make an otherwise well-baked loaf seem underdone. If you want neat slices, wait until it is completely cool and use a serrated knife with a gentle sawing motion.

Serving Suggestions

Serve banana bread at room temperature, when its crumb is soft and the molasses-banana flavor is easy to taste. A plain slice works well for breakfast or an afternoon snack; for a more substantial serving, add a little butter, cream cheese, or nut butter. Toasting a slice brings out a lightly crisp edge, especially if the loaf has been refrigerated.

For dessert, serve a slice with plain yogurt, lightly whipped cream, or a scoop of vanilla ice cream. Keep toppings simple so they complement rather than hide the banana flavor. If serving several people, let the loaf cool fully before cutting it into 10 slices, then offer spreads on the side instead of topping every piece in advance.

Variations

No molasses: Use 1/2 cup (100 g) granulated sugar in place of the brown sugar and omit the molasses. The loaf will still bake successfully, but it will have a cleaner, less caramel-like sweetness and may be slightly less moist. There is no need to add extra liquid; the bananas provide plenty of moisture.

Maple version: Replace the molasses with 1 tablespoon (15 ml) pure maple syrup. This gives a softer, lighter flavor than molasses. Because maple syrup is less concentrated, the finished loaf will not taste quite as much like brown sugar, but the small amount does not require another change to the recipe.

Add-ins: Fold in up to 1/2 cup (60 g) chopped walnuts or pecans, or 1/2 cup (85 g) chocolate chips, after combining the wet and dry mixtures. More add-ins can weigh down the loaf or make it harder to tell whether the center is baked, so keep the total moderate.

Warm spice: Increase the cinnamon to 1 teaspoon (2 g), or add 1/4 teaspoon (0.5 g) ground nutmeg. These spices pair well with banana and molasses, but they are optional; the basic recipe keeps the flavor familiar and lets the fruit lead.

Storage and Reheating

Cool the loaf on a rack, then wrap it or place it in an airtight container and refrigerate it within 2 hours of baking. Refrigerated banana bread keeps well for 3–4 days. Chilling can firm the butter and make slices feel less tender, so bring a piece to room temperature before serving, or warm it briefly.

For longer storage, wrap individual slices or the whole cooled loaf tightly, place it in a freezer-safe bag or container, and freeze for up to 3 months. Thaw wrapped slices in the refrigerator or at room temperature, then unwrap them so condensation does not collect on the surface. To reheat leftovers, warm them in a 325°F (165°C) oven until the center reaches 165°F (74°C), the USDA FSIS recommendation for reheated leftovers. A thermometer is the most reliable way to check; avoid reheating repeatedly, since that dries the crumb.

Frequently Asked Questions

Can I use white sugar instead of brown sugar in banana bread?

Yes. Use the same volume of granulated sugar as the brown sugar called for. The bread will be sweet, but it will lack some of brown sugar’s mellow, caramel-like flavor and may be a little less moist. For a closer match, mix 1/2 cup (100 g) granulated sugar with 1 tablespoon (20 g) molasses for every 1/2 cup of packed brown sugar.

Does the molasses need to be mixed with the sugar first?

No. In this recipe, whisk the molasses into the wet ingredients with the butter, banana, egg, and vanilla. Mixing it with the sugar first can also work, but it is not necessary. If you see a few dark streaks while stirring, continue mixing until the molasses is spread through the banana mixture.

Can I use honey or maple syrup instead?

You can use a small amount for flavor, but liquid sweeteners are not a direct one-for-one substitute for brown sugar because they add more moisture. For this recipe, 1 tablespoon (15 ml) maple syrup can replace the molasses while the granulated sugar stays in place. Replacing all the sugar with honey or syrup would require changing the other ingredients and could make the loaf dense or wet.

Why is my banana bread gummy in the middle?

Common causes include too much mashed banana, excess flour from tightly packed measuring cups, underbaking, or slicing before the loaf has cooled. Weighing the banana and flour helps keep the proportions steady. Check the center with a toothpick and thermometer, and let the baked loaf cool for the full hour before cutting it.

Can I make this recipe without an egg?

A mashed ripe banana can replace the egg, but the loaf will be denser and more moist, and the banana flavor will be stronger. Use about 1/4 cup (60 g) extra mashed banana in place of the egg, keeping the total banana close to 1 3/4 cups (405 g). The crumb may take longer to set, so rely on the center’s texture and temperature rather than the clock alone.
