How to Make Banana Blueberry Oatmeal Muffins
- Preheat oven to 375 degrees. Line muffin with muffin liners. Using two medium sized bowls mix the wet and dry ingredients separately.
- Incorporate the dry ingredients into the wet ingredients, except blueberries. Add blueberries at the end but do not overmix otherwise you will have a blue batter.
- Evenly scoop the batter into the muffin liners.
- In a small bowl mix the ingredients of the topping together and using a small spoon scoop mixture on top of each muffin. Repeat until all the muffins have been topped with the mixture.
- Bake for about 20 minutes or until a toothpick inserted comes out fairly dry. Do not over cook. Remove from oven and let cool for about 15 minutes.
Meal Prep Tips
- Use blueberries that are frozen, do not thaw otherwise they will be melted and contain a lot of liquid and turn the batter blue
- When adding them to the batter, add them as the last ingredient and incorporate them only to evenly distribute them in the batter. Do not overmix as they will turn the batter blue.
- Use non stick cupcake liners. That way the paper won't stick to the muffins and instead it will peel away easy.
Possible Ingredient Substitutions
- Whole wheat flour - Instead of using all-purpose flour, try using whole wheat flour for a healthier option.
- Other berries - Swap the blueberries for raspberries, cranberries or chopped strawberries if you prefer a different berry flavor.
- Vegan - For a vegan version, replace the eggs with a flax or chia seed egg substitute.
- Almond flour - use almond flour or a gluten free flour for a gluten free option
- Fresh blueberries - use fresh berries instead of frozen

Yes, you can use frozen blueberries in muffins. In fact, they tend to hold their shape better during baking and can create a nice burst of juice and flavor in the muffins. However, keep in mind that frozen blueberries may slightly increase the baking time of the muffins. Be sure to gently fold them into the batter while still frozen to prevent them from bleeding too much into the batter.
Oatmeal muffins offer several health benefits, as they are a good source of fiber and protein, which help keep you feeling full and satisfied. Oats are also known to lower cholesterol levels and may reduce the risk of heart disease. Oatmeal muffins with fruit like blueberries provide antioxidants, which can help boost your immune system and reduce inflammation.
Yes, you can freeze muffins with a streusel topping. It is best to freeze them without any additional toppings or glazes. Once the muffins have cooled completely, wrap them tightly in plastic wrap and then place them in an airtight container or freezer bag. They can be frozen for up to 3 months. To reheat, simply let them thaw at room temperature and then reheat in the oven or microwave. Keep in mind that the streusel topping may not be as crisp after freezing and reheating.
