– 1 cup rolled oats
– 1 cup whole wheat flour
– 1/2 cup packed brown sugar
– 1 tablespoon baking powder
– 1/2 teaspoon baking soda
– 1/2 teaspoon salt
– 1 cup buttermilk (or plant-based milk with 1 tablespoon vinegar)

– Zest of 1 lemon
– 1/4 cup fresh lemon juice

Substitutions for Common Ingredients
You can swap buttermilk with plant-based milk mixed with vinegar. This works well. If you don’t have vegetable oil, melted coconut oil is a good choice.

Nutritional Information
Each muffin has about 160 calories. They contain 4 grams of protein and 3 grams of fiber. With 7 grams of sugar, they are a treat that won’t spike your blood sugar too much. The muffins also provide a good source of vitamins from blueberries and lemon.

Step-by-Step Instructions
Prepping the Oven and Muffin Tin
First, preheat your oven to 350°F (175°C). This step is key to getting the muffins just right. Next, grab a muffin tin. You can line it with paper liners or grease it lightly with cooking spray or oil. Both methods work well.
Mixing the Dry Ingredients
In a large bowl, combine the rolled oats, whole wheat flour, brown sugar, baking powder, baking soda, and salt. Whisk these dry ingredients together until they blend well. This mix gives your muffins a great base.
Preparing the Wet Ingredients
In another bowl, whisk together the buttermilk, vegetable oil, eggs, lemon zest, lemon juice, and vanilla extract. Make sure this mixture is smooth. This is where the flavor starts to build.
Combining Wet and Dry Mixtures
Now, pour the wet mixture into the bowl with the dry ingredients. Gently stir with a spatula or wooden spoon. Mix just until combined. It’s okay if there are small lumps. Overmixing can make the muffins tough.
Folding in the Blueberries
Carefully fold in the fresh blueberries. Make sure they spread evenly in the batter. Avoid crushing them, as you want those juicy bursts of flavor in each muffin!
Baking and Cooling
Use a spoon or ice cream scoop to fill each muffin cup about three-quarters full. Bake in your preheated oven for 18-20 minutes. To check if they are done, insert a toothpick in the center; it should come out clean. Once baked, let the muffins cool in the tin for about 5 minutes, then transfer them to a wire rack. Let them cool completely before you enjoy them.
Tips & Tricks
Ensuring Perfect Muffin Texture
To make your muffins soft and fluffy, do not overmix the batter. When you combine the wet and dry ingredients, stir gently. You want to mix just until the flour disappears. A few lumps are okay. This method keeps the muffins light. For a great rise, use fresh baking powder. Always check the expiration date on your baking soda too.
Best Practices for Folding Blueberries
When adding blueberries, be gentle. Use a spatula to fold them in. This keeps the berries whole and juicy. If you crush the berries, your muffins may turn blue. Try to evenly distribute them throughout the batter. If you use frozen blueberries, do not thaw them first. This helps prevent extra moisture in the batter.
How to Store Muffins for Freshness
To keep your muffins fresh, store them in an airtight container. They stay good for about three days at room temperature. If you want them to last longer, freeze them. Just wrap each muffin in plastic wrap. Place them in a freezer bag, and they can last up to three months. When you’re ready to eat, thaw at room temperature or warm in the oven.
Pro Tips
- Use Fresh Ingredients: Always opt for fresh blueberries when in season for the best flavor and texture.
- Don’t Overmix: Mix the batter until just combined to ensure your muffins remain light and fluffy.
- Experiment with Add-ins: Feel free to add nuts or seeds for extra crunch and nutrition.
- Storage Tips: Store muffins in an airtight container at room temperature for up to 3 days or freeze for longer shelf life.
Variations
Different Fruit Additions
You can mix up the fruits in these muffins. Try adding raspberries, strawberries, or blackberries. Each fruit brings a unique taste. For a tropical twist, add chopped mango or pineapple. Just remember to keep the amount similar to the blueberries. Use one cup of any fruit you choose.
Alternative Flours and Sweeteners
Switching flours can change the muffins’ texture and taste. You can use almond flour or oat flour. These flours are gluten-free and give a nice flavor. If you want a sweeter muffin, try using maple syrup or honey instead of brown sugar. Use about half the amount since these sweeteners are stronger.
Gluten-Free Options
If you need gluten-free muffins, switch the whole wheat flour with a gluten-free blend. Many brands offer good mixes that work well in baking. You can also use rolled oats labeled gluten-free. This way, everyone can enjoy these tasty muffins without worry.

Yes, you can use frozen blueberries. They are easy to find and work well. Frozen blueberries do not need thawing. Just fold them into the batter straight from the freezer. This keeps them from staining the batter too much.
