Cinnamon Apple Oat Muffins Under 100 Calories – Light, Cozy, and Easy
These muffins bring the comfort of warm apples and cinnamon without the calorie overload. They’re soft, naturally sweet, and perfect for mornings when you want something homemade but simple. You’ll mix everything in one bowl, pop them in the oven, and enjoy a warm, cozy treat in under 30 minutes.
They taste like a mini apple crisp in muffin form—yet each one stays under 100 calories. Great for breakfast meal prep, snacks, or a light dessert with tea.
Ingredients
Method
- Prep your pan and oven: Heat the oven to 350°F (175°C). Line a 12-cup muffin pan with paper liners or lightly coat with cooking spray.
- Make oat “flour”: Pulse the rolled oats in a blender or food processor 10–15 seconds until coarse, like fine breadcrumbs. You want texture, not a powder.
- Combine dry ingredients: In a large bowl, whisk the processed oats, flour, baking powder, baking soda, cinnamon, and salt.
- Mix wet ingredients: In a separate bowl, whisk the applesauce, Greek yogurt, almond milk, egg, vanilla, and maple syrup until smooth.
- Bring it together: Pour the wet mixture into the dry ingredients. Stir gently until just combined—no dry streaks, but don’t overmix.
- Fold in the apple: Add the diced apple and fold until evenly distributed. The batter will be thick; that’s ideal for tender muffins.
- Portion the batter: Divide into 12 muffin cups. For a light crunch, sprinkle a tiny pinch of turbinado sugar on top of each (optional).
- Bake: Bake 14–17 minutes, or until a toothpick comes out with just a few moist crumbs and the tops spring back.
- Cool: Let the muffins rest in the pan for 5 minutes, then transfer to a wire rack to cool completely. This helps set the crumb and keeps them from turning gummy.
- Enjoy: Serve warm or at room temp. They pair well with tea, coffee, or a smear of almond butter if you have extra calories to spend.

How to Store
- Room temperature: Store in an airtight container for up to 2 days.
Place a paper towel under and over the muffins to absorb moisture.
- Refrigerator: Keeps well for 4–5 days. Warm in the microwave for 10–15 seconds for best texture.
- Freezer: Wrap individually and freeze up to 2 months. Thaw overnight in the fridge, or microwave from frozen for 25–35 seconds.
Health Benefits
- High-fiber oats: Rolled oats support steady energy and can help lower LDL cholesterol.
- Lower sugar load: Apples, applesauce, and a small amount of maple syrup keep sweetness gentle and more balanced.
- Protein boost from yogurt and egg: These help you feel satisfied and support muscle repair.
- Whole grain flour: Provides extra fiber and micronutrients compared to refined flour.
- Fewer saturated fats: No butter or oil needed; moisture comes from yogurt, applesauce, and milk.
Pitfalls to Watch Out For
- Overmixing the batter: This can make muffins tough.
Stir just until combined.
- Cutting apples too large: Big chunks release water unevenly and cause soggy pockets. Keep the dice small and even.
- Skipping liners or spray: These muffins are low in fat and may stick. Use liners or grease the pan well.
- Overbaking: Dryness sneaks up fast with lean batters.
Check early at 14 minutes.
- Too much sweetener: More syrup or honey bumps calories quickly. Stick to the listed amount if you want to stay under 100 calories.
Recipe Variations
- Apple pie spice twist: Swap 1 teaspoon of cinnamon for 1 1/4 teaspoons apple pie spice for a warmer, bakery-style flavor.
- Crumble topping (not under 100 calories): Mix 2 tablespoons oats with 1 teaspoon coconut oil and 1 teaspoon brown sugar; sprinkle lightly before baking.
- No egg: Replace the egg with a flax egg (1 tablespoon ground flax + 3 tablespoons warm water). Texture will be a bit denser but still tender.
- Gluten-free: Use certified gluten-free oats and a 1:1 gluten-free baking blend instead of whole wheat flour.
- Extra protein: Stir in 1–2 tablespoons vanilla or unflavored whey or plant protein powder and add a splash more milk to keep the batter spreadable.
- Cranberry apple: Fold in 2 tablespoons finely chopped dried cranberries for tart pops of flavor (adds a few calories).
- Mini muffins: Bake in a mini pan for 9–11 minutes.
Great for portion control and lunchboxes.
FAQ
Are these really under 100 calories?
Yes—if you stick to the listed amounts and make 12 muffins, each is roughly under 100 calories. Exact numbers vary a bit based on the apple size and sweetener used.
Can I use quick oats instead of rolled oats?
You can. Quick oats will blend even faster and give a slightly softer crumb.
Avoid instant oatmeal packets with sweeteners or flavors.
Do I have to peel the apple?
No. The peel adds fiber and a bit of color. If you prefer a smoother bite, peel it; otherwise, dice very small and keep the skin on.
What if I don’t have Greek yogurt?
Use regular nonfat yogurt, but strain it for 10 minutes to remove excess liquid.
You can also swap with low-fat yogurt; just reduce the milk by a tablespoon if the batter seems thin.
Can I make these without added sweetener?
Yes, but the flavor will be more subtle. Use a very sweet apple and add an extra tablespoon of applesauce for moisture. A pinch more cinnamon helps, too.
Why are my muffins gummy?
Common causes are overmixing, underbaking, or too much moisture from large apple chunks.
Make sure the toothpick comes out with just a few moist crumbs and let them cool on a rack.
How do I reheat them so they taste fresh?
Microwave for 10–15 seconds or toast in a toaster oven at low heat for a few minutes. A warm muffin tastes softer and more aromatic.
Can I add nuts?
Absolutely. Chopped walnuts or pecans are great, but they will raise calories.
Sprinkle a few pieces on top of each muffin rather than mixing a lot into the batter.
