Ingredients You’ll Need

- All-Purpose Flour: This is how many sweet treats begin. It's the structure of baked goods.
- Oats: High in fiber and low in calories. Added to muffins, they provide more nutrients and make them more filling.
- Baking Soda: A leavening agent that helps muffins rise.
- Salt: Actually makes sweet things taste sweeter. It intensifies how we taste sweetness in food.
- Cinnamon: Adds a hint of warmth and spice.
- Unsweetened Applesauce: A great replacement for high-calorie oils in baked goods. It keeps the food moist and the natural sweetness cuts back the need for a lot of sugar.
- Egg Whites: Lower in calories and fat than the whole egg. They add moisture and help hold the muffins together.
- Sugar: Adds sufficient sweetness.
- Water: Adds additional moisture.
- Frozen Blueberries: Hold their shape and color well when used in baked goods. They are also harvested at their best, so you know they'll taste great.
Step-By-Step Instructions

Step 1:
Before getting started, preheat the oven to 350 degrees F and then either line a muffin pan with cupcake liners or spray the pan with cooking spray.
Step 2:
In a large bowl, mix flour, oats, baking soda, cinnamon and salt together.
Step 3:
In the same bowl, add the applesauce, sugar, egg whites and water. Mix until the dry ingredients are blended into the wet ingredients.
Step 4:
Add the frozen blueberries and gently fold into the batter. Pour batter into prepared muffin pan.
Step 5:
Bake for 20 minutes. After 20 minutes, stick a toothpick into the center of one of the muffins. If it comes out clean with a few moist crumbs, they're done.

Expert Tips
- Blueberries are heavier than the batter, so they might sink into the bottom of the muffins. To prevent this, toss the berries in a couple of tablespoons of flour. It helps keep them suspended within the batter.
- For light and fluffy muffins, avoid over-mixing. When adding the blueberries to the batter, be sure to fold them in instead of stirring.
- For sweeter muffins, feel free to sprinkle a little extra cinnamon and sugar on top of each muffin before baking.
- To avoid the batter spilling over the muffin tins, fill each tin no more than ⅔rds of the way full.
- Be careful not to over-bake these muffins as they can easily become too dense and dry.
- To avoid soggy bottoms, do not let your muffins sit in the tin for longer than 5 minutes. If using liners, you can move them to a cooling rack immediately. Otherwise, wait 5 minutes and then move them to a cooling rack.
Variations
- Fold in chopped walnuts with the frozen blueberries for a little added crunch.
- Add chocolate chips to the batter, keeping in mind that any add-ins will up the calorie count.
- Add zest! Zest a lemon and fold it into the batter for a little citrus.
- A reader had great success using half no-calorie sugar and half brown sugar and adding crumbles on top.
Storing & Freezing
- Storing: Place cooled muffins in an airtight container or resealable plastic bag in a single layer and store them at room temperature for up to 3 days.
- Freezing: Place cooled muffins in a freezer-safe resealable bag or wrap them tightly in heavy foil and freeze for up to 3 months.

I so agree with you that blueberries are even better in baked goods than raw. These look so light and yet so flavorful. I bet the applesauce gives it a nice touch of tartness as well.

Can you use fresh blueberries instead of frozen ones?

Hi Kaylee, you can, but fresh is more likely to burst, which isn’t necessarily a negative thing. They’ll just turn your blueberry muffins blue.
