Ingredients
Method
- Prep your pan and oven. Heat the oven to 350°F (175°C). Line a 12-cup mini muffin pan or a 24-cup mini pan depending on size, or lightly grease a standard muffin pan. For under 100 calories, aim for 12 standard muffins at about 95–100 calories each, or 24 minis at about 50 each.
- Hydrate the oats. In a bowl, stir 1 cup rolled oats with 1/2 cup plain nonfat Greek yogurt and 1/2 cup unsweetened applesauce. Let it sit for 10 minutes. This softens the oats and improves texture.
- Whisk the dry mix. In another bowl, combine 1/2 cup whole wheat flour, 1 teaspoon baking powder, 1/4 teaspoon baking soda, 1/4 teaspoon fine salt, and 1/2 teaspoon ground cinnamon. If you like brightness, add 1/2 teaspoon lemon zest.
- Finish the wet mix. To the hydrated oats, add 1 tablespoon neutral oil, 1 large egg white (or 1 small egg), 1 teaspoon vanilla extract, and 3 tablespoons honey or maple syrup. Whisk until smooth.
- Fold in the peaches. Gently stir in 1 cup finely diced ripe peaches (pat dry if using thawed frozen). The smaller the dice, the more evenly the fruit distributes.
- Combine wet and dry. Add the dry ingredients to the wet and fold until just combined. Do not overmix; a few streaks of flour are fine. The batter should be thick but scoopable.
- Portion the batter. Divide evenly among the muffin cups, filling each about 3/4 full. Sprinkle a few oat flakes on top if you like a toasty look.
- Bake. For standard muffins, bake 14–17 minutes; for mini muffins, bake 9–12 minutes. They’re done when a toothpick comes out with a few moist crumbs and the tops spring back.
- Cool properly. Let muffins rest in the pan for 5 minutes, then transfer to a rack. Cooling sets the crumb and keeps them from collapsing.
- Calculate to confirm calories. With the listed amounts and 12 standard muffins, each should land under 100 calories. If you add extra sweetener or larger peach chunks, recheck your portions.
Why This Recipe Works
This recipe leans on rolled oats and a touch of whole wheat flour to create a tender muffin that still feels hearty. Using ripe peaches adds natural sweetness, so we can use less added sugar and still get great flavor.
Greek yogurt keeps the crumb moist without relying on a lot of oil. A small amount of oil helps with texture and prevents dryness, especially around the edges. The balance of moisture, fruit, and whole grains makes these muffins light, satisfying, and reliably under 100 calories each when portioned correctly.

Keeping It Fresh
These muffins stay moist thanks to yogurt and peaches, but moisture also shortens counter life.
Store them in an airtight container lined with a paper towel at room temperature for up to 2 days. For longer storage, refrigerate up to 5 days, or freeze up to 2 months. Freeze on a tray first, then bag to keep them from sticking together. Reheat in the microwave for 10–15 seconds to soften and bring back that just-baked feel.
Why This is Good for You
Each muffin is under 100 calories, yet offers whole grains from oats and whole wheat flour.
Oats bring soluble fiber, which supports steady energy and helps you feel satisfied. Peaches add natural sweetness plus vitamin C and a little potassium. Greek yogurt provides protein and a creamy texture without heavy fat.
This combo makes a smart snack that won’t spike your day but still feels like a treat.
Pitfalls to Watch Out For
- Watery fruit: If using frozen peaches, thaw and pat dry. Extra liquid can make the muffins gummy or underbaked.
- Overmixing: Stir only until the flour disappears. Overworking develops gluten and leads to tough muffins.
- Overbaking: These go from perfect to dry fast.
Start checking a couple of minutes early.
- Portion creep: Overfilling cups raises calories per muffin. Use a scoop to keep portions even.
- Skipping the oat soak: Dry oats can pull moisture from the batter and create a coarse, crumbly texture.
Variations You Can Try
- Ginger Peach: Add 1/4 teaspoon ground ginger or 1 teaspoon minced candied ginger for warmth.
- Almond Twist: Swap vanilla for 1/2 teaspoon almond extract and top with a few sliced almonds. Keep it light to stay under 100 calories.
- Blueberry-Peach Duo: Use 3/4 cup peaches and 1/2 cup blueberries for a mixed-fruit muffin.
- No Refined Sweetener: Replace honey/maple with 2 extra tablespoons unsweetened applesauce and a pinch more cinnamon.
Taste will be less sweet but still pleasant.
- Gluten-Friendly: Use certified gluten-free oats and a 1:1 gluten-free baking blend in place of whole wheat flour. Texture will be slightly more tender.
- Protein Bump: Stir in 1–2 tablespoons vanilla protein powder and add a splash of milk if the batter thickens too much. Check calories if you’re tracking closely.
FAQ
How do I keep these under 100 calories?
Portion control is key.
With the listed amounts, dividing the batter into 12 standard muffins keeps each one just under 100 calories. Measure your sweetener and oil carefully, and don’t overload with extra fruit.
Can I use canned peaches?
Yes, if they’re packed in juice, not heavy syrup. Drain very well and pat dry.
Dice small to prevent pockets of moisture.
What if I don’t have Greek yogurt?
Use regular plain yogurt, but strain it for 10–15 minutes in a fine mesh sieve to thicken. This helps mimic Greek yogurt’s moisture balance.
Do these freeze well?
They freeze beautifully. Cool completely, freeze on a sheet pan, then store in a freezer bag.
Reheat in the microwave for 20–30 seconds or let them thaw at room temperature.
Can I make them vegan?
Yes. Use a flax egg (1 tablespoon ground flax + 3 tablespoons water), plant-based yogurt, and maple syrup instead of honey. Texture will be slightly different but still soft and moist.
Can I bake them as mini muffins?
Absolutely.
Fill mini cups about 3/4 full and start checking at 9 minutes. Mini muffins are great for portion control and quick snacks.
Why are my muffins dense?
Most often, the batter was overmixed or the oats weren’t hydrated long enough. Also check that your baking powder and baking soda are fresh.
Can I add nuts or chocolate chips?
You can, but add sparingly if you want to stay under 100 calories.
A teaspoon of chopped nuts or mini chips per muffin goes a long way.
