Gluten Free Banana Bread – Moist, Easy & One Bowl

If you’ve been searching for a gluten free banana bread that is actually moist, fluffy, and tastes just like the real thing — you just found it. This gluten free banana bread recipe uses one bowl, takes about ten minutes of prep, and comes out perfectly every single time. No mixer needed.

We go through a lot of bananas in our house. There are always a couple that sit just a little too long — too soft to eat, but absolutely perfect for baking. Once I started eating gluten-free, I knew I couldn’t give up banana bread. After plenty of testing, this gluten free banana bread is the one. Nobody can tell it’s gluten-free.

“WOW. Just wow. Absolutely blown away by this banana bread. I will be dreaming about it forever.” – Bruce

Why This Recipe Actually Works

Most gluten free banana bread recipes fail for one of three reasons: they come out gummy in the middle, they sink as they cool, or the texture is dense and heavy. This recipe solves all three.

In regular baking, gluten provides the elastic network that traps air bubbles and holds the bread’s structure. Without it, you need to recreate that structure in other ways. Xanthan gum acts as the binder — it mimics gluten’s sticky, elastic properties and keeps the crumb from falling apart. Most 1-to-1 GF flour blends already include it, but if yours doesn’t, add ¼ teaspoon separately.

Resting the batter for 15 minutes before baking is the other secret. It allows the gluten-free flour to fully hydrate and gives the leavening a head start — this is why the loaf rises with a beautiful dome instead of sinking in the center.

Ingredients

Very ripe bananas – 3 large (about 1 cup mashed) The star of the recipe. Overripe bananas have more sugar and a stronger flavor. Always measure by volume — the size of bananas varies too much to go by count alone.

Unsalted butter, melted – ⅓ cup Adds richness and tenderness. Using melted butter means no mixer needed. Swap for coconut oil or avocado oil for a dairy-free version.

Granulated sugar – ¾ cup Sweetens and helps with browning. You can use light brown sugar for a deeper flavor, or reduce to ½ cup if your bananas are very ripe and sweet.

Large egg – 1, room temperature Provides structure and binds the batter. Room temperature eggs blend more smoothly. For a vegan version, use a flax egg (1 tbsp ground flax + 3 tbsp water, rested 5 minutes).

Pure vanilla extract – 1 teaspoon Enhances the banana flavor. Use pure extract, not imitation — the difference is noticeable in a simple recipe like this.

Baking soda – 1 teaspoon The leavening agent. Make sure yours is fresh — a flat loaf is often a baking soda problem.

Salt – ¼ teaspoon Enhances every other flavor. Don’t skip it.

Gluten-free all-purpose flour with xanthan gum – 1½ cups Use a 1-to-1 blend such as Bob’s Red Mill, King Arthur Measure for Measure, or Pillsbury GF. If your blend doesn’t include xanthan gum, add ¼ teaspoon separately.

How to Make Gluten Free Banana Bread – Step by Step

Step 1 – Preheat and prep Preheat your oven to 350°F (175°C). Grease a 9×5 inch loaf pan with butter or cooking spray. For easy removal, line with parchment paper and leave an overhang on the long sides.

Step 2 – Mash and measure the bananas In a large bowl, mash the bananas with a fork until smooth. Measure to confirm you have about 1 cup. This step matters — too much banana adds excess liquid and makes the bread gummy.

Pro tip: If your bananas aren’t ripe enough, bake them unpeeled at 300°F for 15–20 minutes until the skins turn black. They’ll be perfectly soft and sweet inside.

Step 3 – Mix the wet ingredients Stir in the melted butter, sugar, egg, and vanilla extract into the mashed bananas. Mix until well combined.

Step 4 – Add baking soda and salt Stir in the baking soda and salt. You may notice a slight reaction as the baking soda meets the acidic bananas — that’s exactly what you want.

Step 5 – Add the flour Using the spoon-and-level method, measure your GF flour into the bowl. Stir until just combined. A few dry streaks are okay — do not overmix.

Pro tip: Overmixing gluten-free batter makes it dense and tough. Stir until you no longer see dry flour, then stop.

Step 6 – Rest the batter (the secret step) Let the batter sit at room temperature for 15 minutes before baking. This allows the flour to fully hydrate and gives the loaf a beautiful domed top.

Step 7 – Bake Pour the batter into the prepared pan. Bake on the center rack for 50–60 minutes, until a toothpick inserted in the center comes out clean. If the top is browning too fast, tent loosely with foil and continue baking.

Step 8 – Cool completely before slicing Cool in the pan for 10 minutes, then turn onto a wire rack. Wait at least 20–30 more minutes before slicing. Cutting into warm GF bread traps steam and makes the crumb gummy — patience is worth it.

Tips for the Best Gluten Free Banana Bread

• Always use room temperature ingredients. Cold butter and eggs don’t mix evenly and result in a denser loaf.
• Measure flour with the spoon-and-level method. Scooping directly from the bag packs the flour and can add up to 30% more than intended, making the bread dry and crumbly.
• Use very ripe bananas. Brown, heavily spotted bananas give the most flavor. If yours are too firm, freeze them overnight and thaw completely before using.
• Not all GF flours behave the same. Stick to a 1-to-1 blend with xanthan gum. Avoid single-ingredient flours like almond or coconut flour without significant recipe adjustments.
• Don’t open the oven before 40 minutes. Early peeking causes the center to sink.

Troubleshooting Your Gluten Free Banana Bread

Gluten free banana bread can be tricky at first. Here are the most common problems and how to fix them:

Bread is gummy in the middle Almost always a liquid-to-flour imbalance. Measure your bananas by volume (1 cup), not by count. Also make sure the bread is fully cooled before slicing.

Bread sank in the center The batter wasn’t rested before baking, the oven was opened too early, or your baking soda has lost its potency.

Texture is dense and heavy The batter was overmixed after adding the flour, or the ingredients were cold when combined.

Bread is dry and crumbly Too much flour. Use the spoon-and-level method every time.

Top browned but inside was raw Your oven runs hot. Reduce temperature to 325°F, bake longer, and tent the top with foil after 40 minutes.

Substitutions

Dairy-free: Replace butter with melted coconut oil or avocado oil in equal amounts.

Vegan: Use coconut oil instead of butter and a flax egg instead of the regular egg (1 tbsp ground flax + 3 tbsp water, rest 5 minutes before using).

Less sugar: Reduce to ½ cup, especially if your bananas are very ripe. Going lower than that will affect the texture of the loaf.

Applesauce instead of butter: Possible, but the bread will be less rich and noticeably denser. Coconut oil is a better substitute.

Gluten Free Banana Bread Variations and Mix-ins

One of the best things about this gluten free banana bread is how easy it is to customize. Fold ½ cup of any of the following into the batter along with the flour:

Chocolate chip: Use mini chips — they distribute more evenly and don’t sink to the bottom.

Blueberry: Fresh or frozen. If frozen, don’t thaw first — fold them in straight from the freezer.

Walnuts or pecans: Chop roughly and toast in a dry pan for 3–4 minutes before adding. Toasting deepens the flavor.

Cinnamon swirl: Mix 2 tbsp sugar with 1 tsp cinnamon. Pour half the batter into the pan, sprinkle the cinnamon sugar, add the rest of the batter, and swirl gently with a knife.

How to Store Gluten Free Banana Bread

Room temperature: Up to 2 days in an airtight container.

Refrigerator: Up to 5 days. Wrap tightly or use an airtight container. Let slices come to room temperature before eating, or warm in the microwave for 15 seconds.

Freezer: Up to 3 months. This bread freezes beautifully. Slice first, wrap each slice individually in plastic wrap, then freeze in an airtight bag. Thaw overnight in the fridge or for 1–2 hours at room temperature.
