Not a cupcake in disguise. These are mini muffins you can hand to a toddler without guilt, or grab yourself when you need something that tastes like a real baked good but isn’t loaded with sugar and fat. The trick is letting banana and Greek yogurt do the heavy lifting for moisture and structure, while whole wheat flour adds fiber without turning the crumb into cardboard.
Blueberries stay suspended instead of sinking into a soggy layer at the bottom, which is the usual failure with fruit muffins this small. That’s the kind of detail that makes these baby blueberry banana yogurt muffins worth baking, not just scrolling past.
The first time I made these, all the blueberries sank to the bottom and turned the muffin bases purple and mushy.
Toss frozen blueberries with flour before folding in
Frozen wild blueberries are smaller and hold shape better than fresh; they don’t crush as easily when stirred into batter. Coating them with 1 tablespoon of flour before folding creates a dry surface that grips the batter, keeping them suspended evenly throughout each muffin.
Now I always toss the frozen blueberries with a tablespoon of flour before folding them in, they stay suspended and hold their shape through baking. No blue streaks bleeding into the crumb, just tidy little pockets of fruit.
Banana plus yogurt replaces extra fat
Mashed ripe banana does more than sweeten, it packs the batter with moisture that keeps these mini muffins tender without drowning them in oil. Greek yogurt brings protein and a subtle tang, and its thickness gives structure that would otherwise come from more butter or coconut oil. Together they create a soft, springy crumb that doesn’t taste lean.
You get a full-flavored muffin that’s actually lighter on added fat, which matters when feeding these as a snack.
White whole wheat flour for a lighter whole-grain texture
White whole wheat flour comes from a different wheat variety than standard whole wheat; it has milder flavor and finer texture, so it doesn’t overwhelm the banana and blueberry. Since it contains the whole grain, you get more fiber than all-purpose flour, but the gluten development stays lower because whole-wheat flours absorb more liquid and form less elastic dough. That’s why these muffins turn out tender, not dense or dry.
A healthy choice that still tastes like a treat.

Ingredient notes for these blueberry banana mini muffins
Very ripe banana: Use one medium banana with brown spots for maximum sweetness and moisture; underripe banana won’t mash smooth.
Frozen wild blueberries: Small wild blueberries hold shape better than larger cultivated ones; thaw and drain well to avoid excess liquid.
White whole wheat flour: Milder than standard whole wheat, it gives a lighter texture while still adding fiber; all-purpose works too.
Plain Greek yogurt: Full fat or 2% Greek yogurt provides the best structure and tang; avoid nonfat, which can make muffins dry.
Unrefined coconut oil: Melted coconut oil adds a subtle flavor; butter is a fine swap, but use unsalted if you add the optional salt.
How to tell when these mini muffins are just right
Whisk wet ingredients until uniform
Beat the banana, egg, oil, yogurt, and vanilla into a single pale, creamy mixture. Any streaks of egg white or oil pockets will affect the crumb, so keep whisking until it looks like a thin smoothie.
Fold flour just until no dry streaks remain
Switch to a spatula and stir the flour mixture into the wet batter with a few broad strokes. Stop the moment the last white streak disappears. Overmixing activates gluten, making muffins tough rather than tender.
Fold in floured blueberries gently
Scatter the floured berries over the batter and fold with two or three turns. You should see even blue specks but no purple swirls. If the batter turns blue, you crushed the berries, next time fold lighter.
Drop batter by tablespoonfuls into prepared pan
Use a #60 scoop or two spoons to fill each cup almost to the rim. The batter should mound slightly above the edge. Wipe any drips off the pan so they don’t burn onto the muffin sides.
Bake until toothpick comes out clean
Start checking at 11 minutes. Insert a toothpick into the center of a muffin in the middle of the pan; it should emerge with a few moist crumbs but no wet batter. The tops will be pale golden and spring back when pressed.
Rest in the pan before turning out
Let the muffins sit in the pan for at least 5 minutes after baking. The steam finishes setting the interior structure. If you try to lift them too soon, the bottoms will tear and stick to the liners.

Baby Blueberry Banana Yogurt Muffins
Ingredients
- 1/2 cup mashed very ripe banana 1 medium
- 1 large egg
- 2 tbsp melted unrefined coconut oil or butter
- 1/4 cup plain Greek yogurt
- 1/2 tsp vanilla
- 3/4 cup white whole wheat flour (or all purpose), divided
- 1/2 tsp aluminum free baking powder
- 1/4 tsp baking soda
- pinch salt optional
- 1/2 cup frozen wild blueberries, thawed and drained
Instructions
Preheat oven and prep pan:
Preheat oven to 350°F (175°C). Prepare a mini muffin pan by lining with paper liners or using a silicone pan; lightly grease with oil to avoid sticking.Mash banana and measure:
Thoroughly mash the banana until smooth, then measure 1/2 cup.Coat blueberries with flour:
Combine the blueberries with 1 tbsp of the flour, tossing to coat; this keeps them from sinking during baking.Whisk wet ingredients:
In a large bowl, whisk together the mashed banana, egg, melted coconut oil, yogurt, and vanilla until uniform.Mix dry ingredients:
Add the remaining flour, baking powder, baking soda, and salt (if using), stirring just until no dry streaks remain.Fold in blueberries:
Carefully fold the floured blueberries into the batter.Fill muffin cups:
Drop the batter by 1 tablespoonfuls into the prepared muffin cups.Bake until done:
Bake for 11-15 minutes, testing with a toothpick inserted in the center—it should come out clean.Cool in pan:
Allow the muffins to rest in the pan for at least 5-10 minutes before turning out onto a rack.

Swap the banana? Not so fast, here’s what works and what doesn’t
Banana: 1/2 cup unsweetened applesauce or 1/2 cup mashed ripe pear. Applesauce makes muffins moister and less sweet, so you may need an extra tablespoon of sugar.
Pear adds similar moisture but milder flavor; the crumb will be slightly more delicate. Don’t use pumpkin or sweet potato, they’re too dense and change the texture entirely.
Greek yogurt: Sour cream or buttermilk (use same amount, 1/4 cup). Sour cream gives the same tang and moisture with a slightly richer crumb. Buttermilk makes the batter thinner, so the muffins spread more and rise less; reduce liquid elsewhere by 1 tablespoon if you swap.
Avoid nonfat yogurt or milk, they’ll make the crumb dry.
White whole wheat flour: All-purpose flour, 1:1 by volume (3/4 cup). All-purpose gives a lighter, softer crumb with less fiber. No other adjustments needed.
Don’t use standard whole wheat flour without reducing it to 1/2 cup plus 2 tablespoons and adding 1 tablespoon of liquid, it will make the muffins dense.
Coconut oil: Melted unsalted butter or neutral oil (like avocado or grapeseed), same amount (2 tablespoons). Butter adds richness and a firmer crumb; the flavor is more savory.
Neutral oil keeps the muffins tender but less flavorful. Avoid olive oil, its flavor clashes with blueberry and banana.
Storage and Serving
Store leftover muffins in an airtight container at room temperature for up to 3 days. The crumb stays tender the first day; by day 2, the berries release a bit of moisture, making the muffins slightly softer but still pleasant. For longer storage, freeze them in a single layer in a freezer bag for up to 3 months.
Thaw at room temperature for about 30 minutes. If you reheat, wrap a muffin in a paper towel and microwave for 10 seconds to restore some warmth and softness. Don’t refrigerate the muffins.
The fridge dries out baked goods faster than the freezer and speeds up staling. These muffins are best eaten within a few hours of baking when the exterior is still slightly crisp and the interior is moist.
No finishing touch is added at the end.
Tips
- Use a #60 cookie scoop to portion the batter; it ensures all muffins are the same size so they bake evenly in the short 11-to-15-minute window.
- Let the muffins cool in the pan for a full 10 minutes before turning out; the steam finishes setting the tender crumb and prevents the bottoms from tearing.

Frequently Asked Questions
Can I use fresh blueberries instead of frozen?
Fresh blueberries work, but they’re larger and more fragile. They’ll sink and burst more easily than the smaller wild frozen ones. If you swap, toss them with flour too, but expect some blue streaking in the crumb.
Wild frozen blueberries are the best fit for this recipe.
How do I know when the mini muffins are done baking?
Insert a toothpick into the center of a muffin from the middle of the pan. It should come out with a few moist crumbs but no wet batter.
The tops will be pale golden and spring back when you press them. Start checking at 11 minutes; the full window is 11 to 15 minutes.
Can I make these muffins ahead and freeze them?
Yes, freeze them in a single layer in a freezer bag for up to 3 months. Thaw at room temperature for about 30 minutes. To reheat, wrap a muffin in a paper towel and microwave 10 seconds.
Don’t refrigerate them, the fridge dries out baked goods faster than the freezer.
Why did my blueberries sink to the bottom of the muffins?
Most likely you skipped tossing the blueberries with flour before folding them in. That coating helps the batter grip the berries so they stay suspended.
Also, if the batter was too thin, maybe from overripe banana or not draining the thawed berries, the fruit will sink. Toss them with 1 tablespoon of flour next time and make sure your yogurt isn’t watery.
