This healthy blueberry banana bread is soft, moist, and loaded with fresh blueberries. Made with almond and oat flour, it's gluten-free, oil-free, and naturally sweetened with just ripe bananas and a splash of maple syrup — one bowl, one hour, and the kind of loaf I keep on the counter all week.
Prep the pan. Preheat the oven to 350°F and line a bread tin with parchment paper or grease it well.
Make homemade oat flour (optional). If you're making your own, add 1.5 cups of rolled oats to a blender and blend until fine, about 20 seconds to 1 minute. Measure out 1 cup of flour.
Whisk the dry ingredients. In a small mixing bowl, whisk together the almond flour, oat flour, cinnamon, baking powder, baking soda, and salt. Set aside.
Whisk the wet ingredients. In a large mixing bowl, whisk together the eggs, mashed bananas, maple syrup, and vanilla extract until fully combined.
Combine and fold in blueberries. Add the dry ingredients to the wet and mix until just combined. Gently fold in the blueberries with a spatula, then pour the batter into the prepared bread tin.
Bake. Bake for 50–60 minutes, or until a toothpick inserted in the center comes out clean.
Cool completely. Let the bread cool fully in the pan before slicing — this is what gives you a clean crumb instead of a gummy center.
Notes
Homemade oat flour: Add 1.5 cups of rolled oats to a blender and blend until fine, about 20 seconds to 1 minute. Measure out 1 cup for this recipe.Store-bought oat flour: Works great — just don't pack it into the measuring cup. Spoon and level, or the loaf will turn out dry.Almond flour: Use blanched almond flour, not almond meal. I don't recommend Trader Joe's brand — it runs coarse and makes the loaf mushy. Bob's Red Mill is my go-to.Bananas: Use very ripe bananas with lots of brown spots. Yellow bananas won't give you enough sweetness or moisture.Blueberries: Fresh or frozen, both work. If using frozen, toss them in a teaspoon of oat flour before folding them in so they don't sink.Storing: Store in an airtight container at room temperature or in the fridge for up to 5 days.Freezing: Slice the loaf, then store slices in a freezer-safe bag for up to 3 months. Thaw at room temperature for 30 minutes or microwave for 20 seconds.
