Healthy Blueberry Muffins Under 100 Calories – Light, Easy, and Delicious
These blueberry muffins are soft, juicy, and taste like a treat, but each one stays under 100 calories. They’re perfect for breakfast on the go, a light snack, or something sweet after dinner without the sugar crash. The batter comes together in one bowl, and the ingredients are simple pantry staples.
You’ll get a tender crumb, bright blueberry bursts, and a hint of vanilla in every bite. Best of all, they freeze well and reheat beautifully.
Ingredients
Method
- Preheat and prep. Heat your oven to 400°F (200°C). Line a 12-cup muffin pan with paper liners or lightly coat with nonstick spray.
- Mix the dry. In a medium bowl, whisk 3/4 cup white whole wheat flour, 3/4 cup oat flour, 1 1/2 teaspoons baking powder, 1/4 teaspoon baking soda, 1/4 teaspoon salt, and 1/2 teaspoon cinnamon.
- Whisk the wet. In a large bowl, whisk 1/2 cup plain nonfat Greek yogurt, 1/3 cup unsweetened almond milk, 1 large egg, 1 tablespoon light olive oil, 1 teaspoon vanilla, and 1/3 cup granulated sweetener. Add 1 teaspoon lemon zest if using.
- Combine gently. Add the dry ingredients to the wet and stir with a spatula just until no dry spots remain. The batter should be thick but scoopable. If needed, add 1–2 teaspoons more milk.
- Fold in berries. Toss 3/4 cup blueberries with 1 teaspoon flour (prevents sinking), then gently fold into the batter. If using frozen, do not thaw.
- Portion. Divide batter evenly among the 12 cups. Aim for about 2 tablespoons per muffin. Sprinkle a few extra blueberries on top if you like.
- Bake hot, then finish. Bake at 400°F for 5 minutes to help the muffins rise, then reduce heat to 350°F (177°C) and bake 8–10 more minutes. They’re done when a toothpick comes out clean or with a few moist crumbs.
- Cool. Let muffins rest in the pan for 5 minutes, then transfer to a rack to finish cooling. This keeps them light and prevents sogginess.
What Makes This Special
These muffins keep the flavor and texture you love while trimming extra sugar and fat. Instead of heavy butter, they use a mix of Greek yogurt and a touch of oil for moisture and softness. Oat flour and white whole wheat flour boost fiber without making the muffins dense.
A little lemon zest brightens the blueberries, and vanilla adds warmth. The result: real bakery taste at a fraction of the calories.

Keeping It Fresh
These muffins stay soft at room temperature for 2–3 days in an airtight container. Add a paper towel to the container to absorb extra moisture.
For longer storage, freeze in a single layer, then move to a freezer bag for up to 3 months. Reheat in the microwave for 15–20 seconds or warm in a 300°F oven for 5–7 minutes.
Benefits of This Recipe
- Under 100 calories per muffin when portioned as directed and made with a 1:1 zero-calorie sweetener or reduced sugar.
- Higher in protein thanks to Greek yogurt and egg, helping with fullness.
- More fiber from oat flour and whole wheat flour for steady energy.
- Lower in fat but still moist, using just a small amount of heart-healthy oil.
- Quick to make: one bowl for wet, one for dry, and about 15 minutes of bake time.
- Kid-friendly and great for lunchboxes or pre-workout snacks.
Common Mistakes to Avoid
- Overmixing the batter. This toughens the muffins. Stir just until combined.
- Overbaking. Dry muffins happen fast.
Start checking early, especially if your oven runs hot.
- Skipping the initial high heat. That first 5 minutes at 400°F gives a better rise and a taller dome.
- Adding too many berries. It can weigh down the batter and cause soggy centers. Stick to about 3/4 cup for 12 muffins.
- Using the wrong flour swap. Regular whole wheat flour can be too heavy. Choose white whole wheat or pastry flour for a softer crumb.
Variations You Can Try
- Lemon Blueberry: Add 1 additional teaspoon lemon zest and 1 tablespoon lemon juice.
Increase sweetener slightly if needed.
- Almond Crunch: Stir in 1/4 teaspoon almond extract and sprinkle sliced almonds on top before baking.
- Protein Boost: Replace 1/4 cup oat flour with 1/4 cup unflavored or vanilla whey protein. Add a splash more milk if batter is thick.
- Gluten-Free: Use certified gluten-free oat flour and a 1:1 gluten-free baking blend instead of white whole wheat.
- No-Sugar-Added: Use a granulated monk fruit or erythritol sweetener. Check sweetness to taste.
- Mixed Berry: Swap half the blueberries for raspberries or chopped strawberries.
FAQ
How are these under 100 calories?
Portion size and ingredients make the difference.
Using Greek yogurt, a small amount of oil, and a measured amount of sweetener keeps each muffin under 100 calories when the batter is divided into 12 standard muffins. If you use regular sugar, the calories are still low; a 1:1 zero-calorie sweetener lowers them further.
Can I use only all-purpose flour?
Yes. Replace the white whole wheat and oat flour with the same total amount of all-purpose flour.
The muffins will be slightly lighter in color and still tender. Fiber will be a bit lower, so consider adding 1 tablespoon ground flaxseed.
Do frozen blueberries work?
Absolutely. Use them straight from the freezer and toss with a teaspoon of flour before folding in.
Don’t thaw, or the muffins may turn purple and bake up wet.
Can I make these dairy-free?
Yes. Use a thick dairy-free yogurt (coconut or almond) and a non-dairy milk. Check consistency; if your yogurt is thinner, reduce the milk slightly.
How do I keep muffins from sticking to the liners?
Use quality paper liners or silicone liners and give them a light spray.
Let muffins cool 10–15 minutes before peeling off the liner to prevent tearing.
Can I make mini muffins?
Yes. Spoon into a greased mini muffin pan and bake at 400°F for 3 minutes, then 350°F for 6–8 minutes total. You’ll get about 24–28 minis; adjust calorie count accordingly.
Why did my muffins sink?
Common causes include underbaking, too much liquid, or opening the oven door early.
Measure carefully, keep the initial high heat, and bake until the centers spring back lightly to the touch.
