The Simple Muffin That Changed My Morning Routine
Let me tell you when I first tried to make a blueberry mug muffin, I wasn’t trying to create a recipe for the blog. I just needed a quick pick-me-up one morning. It had been a long night, and I was staring into my pantry, hoping inspiration would strike. There were blueberries in the fridge, some oat flour on the shelf, and I thought, “What if I just made a single muffin… in a mug?”
I grew up in Indiana, where muffins were baked by the dozen and usually reserved for Saturdays or potlucks. But here in Asheville, life’s a little different. I don’t always have time or a reason to make a whole batch. That morning, I wanted something cozy and satisfying, like the muffins my grandmother made, but healthier and faster. And that’s how this recipe was born.
I combined a few ingredients, gave it a stir, and stuck it in the microwave. One minute later, I had a warm, fluffy muffin, bursting with juicy blueberries and I was hooked.
Since then, I’ve tested and refined the recipe dozens of times. It’s not just a quick breakfast; it’s my go-to when I need a comforting snack or a little treat without the guilt. The best part? You can customize it based on what you have. Swap the milk, use frozen berries, add lemon zest make it yours.
If you’re someone who values flavor and feeling good, you’re going to love this recipe. And if you’re a fan of minimalist desserts, you’ll probably enjoy our 3-ingredient mug cake too.

How to Make an Easy Blueberry Mug Muffin (That Actually Works)
Quick Steps for a Fluffy, Fruity Treat in Minutes
You don’t need to be a baker to whip up a soft, delicious, easy blueberry mug muffin. This is the kind of recipe you can make in your pajamas with one mug, one spoon, and five minutes.
Here’s how to do it right every time:
- Choose your mug. Pick a microwave-safe mug that’s at least 10 oz to prevent overflow.
- Mix dry ingredients. Add 3 tablespoons oat flour, 1/4 teaspoon baking powder, and a pinch of cinnamon (if using) right into the mug. Stir well.
- Add wet ingredients. Pour in 1 tablespoon maple syrup, 2 tablespoons milk, 1/4 teaspoon vanilla extract, and 1 tablespoon Greek yogurt (optional, but adds richness). Stir until smooth.
- Fold in blueberries. Gently stir in 2 tablespoons of fresh or frozen blueberries. Don’t overmix.
- Microwave. Heat on high for 60–90 seconds. The muffin should rise and look set on top.
- Cool and enjoy. Let it cool for 1 minute (it will be hot!). Grab a spoon and dig in.
💡 Pro Tip: Microwave times vary. Start with 60 seconds and check the center with a spoon. Still gooey? Microwave in 10-second bursts until it’s cooked through.
Once you make this once, it becomes second nature. You’ll find your own rhythm your preferred sweetness level, how many blueberries you love, or if you want to sneak in a few white chocolate chips (highly recommended!).
Mistakes to Avoid When Making Mug Muffins
Even simple recipes can flop if you’re not careful. Here are the most common mistakes people make with an easy blueberry mug muffin and how to avoid them:
- Overmixing the batter: Stir just until combined. Overmixing makes it gummy.
- Adding too many blueberries: Keep it to about 2 tablespoons. More than that and your muffin won’t rise.
- Using too much flour: If your mug muffin feels dry, double-check your flour scoop. Lightly spoon it in, don’t pack it.
- Microwaving too long: Dry, rubbery muffins happen fast. Stick with short bursts and check as you go.
- Forgetting to grease the mug: Even with a nonstick mug, a light spray helps you scoop every bite.
