Prep & Cook Time
Prep Time: 15 minutes
Cook Time: 25 minutes
Total Time: 40 minutes
Servings: 12 muffins
Ingredients
- cooking spray
- 2 medium overripe bananas (mashed (about 1 cup))
- 1 large egg (room temperature)
- ½ cup maple syrup
- 1 tsp pure vanilla powder (use half this amount if you prefer less rich vanilla flavor)
- ⅓ cup vegetable oil
- ¼ cup plain Greek yogurt (room temperature)
- 1 ½ cup all-purpose flour
- 1 cup old fashioned oats
- 1 ½ tsp baking powder
- 1 tsp baking soda
- ½ tsp salt
- ½ tsp ground cinnamon
- 1 cup blueberries (fresh or frozen)
Instructions
- Preheat your oven to 350°F (175°C). Grease a 12-cup standard muffin tin with cooking spray or line with paper liners.
- In a large bowl, mash the 2 medium overripe bananas until mostly smooth. Add the 1 large egg, ½ cup maple syrup, 1 tsp pure vanilla powder (use half this amount if you prefer less rich vanilla flavor), ⅓ cup vegetable oil, and ¼ cup plain Greek yogurt. Whisk until the wet ingredients are well combined.
- In a separate medium bowl, whisk together the 1 ½ cup all-purpose flour, 1 cup old fashioned oats, 1 ½ tsp baking powder, 1 tsp baking soda, ½ tsp salt, and ½ tsp ground cinnamon.
- Gently fold the dry ingredients into the wet ingredients using a spatula until just combined. Be careful not to overmix; a few streaks of flour are okay.
- Toss the 1 cup blueberries in a tablespoon of the flour mixture from the bowl (this helps prevent sinking). Gently fold the blueberries into the muffin batter.
- Divide the batter evenly among the 12 prepared muffin cups, filling each about ¾ full.
- Bake for 20-25 minutes, or until the tops are golden and a toothpick inserted into the center of a muffin comes out clean or with a few dry crumbs.
- Allow the muffins to cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
Variations
- Topping Twist: Before baking, sprinkle the tops with a mix of oats and a light dusting of cinnamon sugar for extra texture.
- Mini Muffins: Pour the batter into a mini muffin tin and reduce the baking time to 12-15 minutes for a bite-sized treat.
- Flavor Infusion: Add a teaspoon of lemon zest to the batter to brighten up the blueberry flavor.
- Double Berry: Substitute half of the blueberries with raspberries or chopped strawberries for a mixed berry version.
Tips for Success
- Room temperature ingredients are key for an even mix and better rise. Take your egg and yogurt out about 30 minutes before baking.
- Do not overmix the batter. Stir just until the flour disappears; this ensures tender, not tough, muffins.
- Fill any empty muffin cups in your pan with a little water to protect the pan and ensure even baking for your muffins.
Storage & Reheating
Store cooled muffins in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days. For longer storage, freeze for up to 3 months. To reheat, warm in the microwave for 15-20 seconds or in a 300°F oven for 5-10 minutes until warm.
FAQ
Can I use quick oats instead of old fashioned?
Yes, but the texture will be slightly less chewy and more uniform.
My berries sank to the bottom. How can I prevent this?
Tossing them in a little flour before folding them in is the best trick. Also, ensure your batter isn’t too thin, and avoid over-stirring once they’re added.
Can I make this recipe into a loaf?
You can. Pour the batter into a greased 9×5-inch loaf pan and bake at 350°F for 50-60 minutes, until a tester comes out clean.
Why do my bananas and yogurt need to be room temperature?
Room temperature ingredients emulsify better with the oil and syrup, creating a smoother batter and more uniform crumb. Cold ingredients can lead to dense muffins.
Can I use honey instead of maple syrup?
Yes, you can use an equal amount of honey. The flavor will be slightly different but still delicious.
Can I omit the Greek yogurt?
The yogurt adds moisture and a slight tang. You can substitute it with an equal amount of sour cream or applesauce in a pinch.
