These blueberry banana oat bars are the perfect breakfast on the go or delicious snack to have on hand, especially if you have little ones! They are naturally sweetened with banana, are incredibly nutrient dense, and are so easy to make.
Prep the pan and preheat oven. Preheat oven to 350. Grease a loaf pan with butter and line with parchment paper for easy removal.
Mix wet ingredients. In a large bowl, add the mashed banana, kefir, egg, and nut butter. Stir until fully combined and smooth.
Add dry ingredients. Stir in the oats, oat flour, flaxseed, baking powder, and cinnamon until just combined.
Fold in blueberries. Gently stir in the frozen blueberries, being careful not to overmix.
Bake. Pour the mixture into the prepared loaf pan. Bake for 30–35 minutes, or until set and soft but not doughy in the center. Let cool before slicing. Enjoy these blueberry banana oat bars!
Notes
Use a very ripe banana for the best sweetness and texture.
Don’t overbake. These blueberry banana oat bars should be moist and tender, not dry.
Let them cool completely before slicing for clean edges.
Use frozen blueberries straight from the freezer to prevent excess moisture.
Want more protein? Add collagen, Greek yogurt on top, or enjoy with nut butter.
Let muffins cool completely before storing in an airtight container in the refrigerator for up to 5 days.
