Ingredients
- 2 medium ripe bananas (about 200g peeled)
- 2 large eggs
- 1/4 cup (60ml) unsweetened almond milk
- 1/4 cup (60ml) light olive oil or melted coconut oil
- 1 teaspoon vanilla extract
- 1/3 cup (65g) granulated erythritol or monk fruit sweetener
- 1 1/4 cups (125g) gluten free old-fashioned rolled oats
- 1 cup (100g) blanched almond flour
- 2 tablespoons coconut flour
- 1 1/2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon salt
- 1/3 cup (35g) chopped walnuts or pecans (optional)
Instructions
- Preheat your oven to 350°F (175°C). Line a 9×5-inch (23x13cm) loaf pan with parchment paper, letting the sides overhang for easy removal. Lightly grease if desired.
- In a large mixing bowl, mash the ripe bananas with a fork until mostly smooth, leaving a few small chunks for texture.
- Add the eggs, almond milk, oil, vanilla extract, and erythritol (or monk fruit sweetener). Whisk until well combined and smooth.
- In a separate bowl, stir together the oats, almond flour, coconut flour, baking powder, baking soda, cinnamon, and salt until evenly mixed.
- Gradually add the dry ingredients to the wet ingredients, stirring gently with a spatula until just combined. Do not overmix; a few lumps are fine.
- If using, fold in the chopped nuts.
- Pour the batter into the prepared loaf pan and smooth the top with a spatula. Tap the pan lightly on the counter to release any air bubbles.
- Bake for 45-55 minutes, or until a toothpick inserted into the center comes out mostly clean (a few moist crumbs are okay). If the top browns too quickly, loosely tent with foil after 35 minutes.
- Remove from the oven and cool in the pan for 10-15 minutes. Then lift the bread out using the parchment overhang and transfer to a wire rack to cool completely before slicing.
- Slice and enjoy! For best texture, let the bread cool fully before cutting.
Tips
- Substitutions: Swap almond milk for any unsweetened plant milk. Coconut oil adds a subtle flavor, while light olive oil keeps it neutral.
- Oat Texture: For a finer crumb, pulse the oats in a food processor for 10-15 seconds before using. For more texture, use whole rolled oats.
- Banana Ripeness: Use bananas with plenty of brown spots for natural sweetness and moisture. Avoid green or underripe bananas.
- Sweetener Notes: Erythritol and monk fruit are both low glycemic. Adjust to taste, but avoid honey, maple syrup, or agave for a diabetic-friendly loaf.
- Don’t Overmix: Stir until just combined to avoid a dense or gummy bread.
Serving Suggestions
- Enjoy warm with a pat of butter or a dollop of Greek yogurt for breakfast.
- Serve with a handful of berries for extra fiber and antioxidants.
- Pair with a cup of unsweetened tea or coffee for a filling snack.
- Top with a sprinkle of cinnamon or a few chopped nuts for crunch.
- Slice thin for a light dessert, or toast for a satisfying afternoon treat.
Variations
- Chocolate Chip Banana Oat Bread: Fold in 1/4 cup (40g) sugar-free chocolate chips for a decadent twist.
- Berry Banana Bread: Gently fold in 1/2 cup (60g) fresh blueberries or raspberries for bursts of fruit.
- Seed Mix-Ins: Add 2 tablespoons chia seeds or flaxseeds for extra fiber and omega-3s.
- Nut-Free Version: Replace almond flour with sunflower seed flour and skip the nuts for an allergy-friendly loaf.
- Spice It Up: Add a pinch of nutmeg or ginger for added warmth.
Storage and Reheating
Let the banana oat bread cool completely before storing. Wrap the loaf tightly in plastic wrap or foil, or store slices in an airtight container. It will keep at room temperature for up to 2 days, or in the refrigerator for up to 5 days. For longer storage, freeze individual slices wrapped in parchment and placed in a freezer bag for up to 2 months.
To reheat, warm slices in the microwave for 15-20 seconds, or toast gently in a toaster oven until heated through. Avoid overheating, as this can dry out the bread.
Frequently Asked Questions
- Can I make this banana oat bread entirely without oats?
Yes, you can omit the oats and use a combination of extra almond flour and a little coconut flour to help bind the loaf. However, oats provide structure and fiber, so the texture will be more cake-like and less hearty. For a true low carb, oat-free version, use 1 1/2 cups almond flour and 1/4 cup coconut flour, and check doneness a few minutes earlier. - Is this banana bread suitable for type 2 diabetics?
This recipe is designed with diabetes management in mind. It uses low glycemic sweeteners, is free from refined sugars, and keeps carbohydrate content lower than traditional banana bread by using almond and coconut flours. However, bananas do contain natural sugars, so portion control is important. Always consult your healthcare provider for individual dietary advice. - Can I use a different sweetener?
Absolutely. Erythritol and monk fruit are popular for their low glycemic index and minimal impact on blood sugar. You can also use allulose or stevia blends. Avoid honey, maple syrup, or coconut sugar if you want to keep it diabetic friendly. Adjust the amount to your preferred sweetness, as some sweeteners are more potent than others. - Why is my banana bread gummy or dense?
This can happen if the batter is overmixed, or if too much moisture is present. Make sure to measure the bananas (about 200g peeled) and not add extra, and only mix until combined. Also, check your baking powder and baking soda are fresh, as old leaveners lose their effectiveness. - Is this bread safe for those with celiac disease?
Yes, as long as you use certified gluten free oats and ensure all other ingredients are gluten free, this recipe is suitable for people with celiac disease. Always double-check packaging for cross-contamination warnings. - Can I make muffins instead of a loaf?
Yes, the batter works wonderfully for muffins. Divide evenly among 10-12 lined muffin cups and bake at 350°F (175°C) for 18-22 minutes, or until a toothpick inserted in the center comes out clean. Cool in the pan for 5 minutes, then transfer to a rack.
