Key Ingredients for Blueberry Muffins Oat Flour
Dry Ingredients:
- 2 cups oat flour (or 2 cups old-fashioned oats, ground)
- 1/2 cup granulated sugar
- 2 teaspoons baking powder
- 1/2 teaspoon salt
- 1/2 teaspoon cinnamon
Wet Ingredients:
- 2 large eggs, room temperature
- 3/4 cup milk (dairy or non-dairy)
- 1/4 cup melted butter or coconut oil
- 1/4 cup Greek yogurt or applesauce
- 1 teaspoon vanilla extract
Add-ins:
- 1 cup fresh or frozen blueberries
- 1 tablespoon flour (for coating berries)

Step-by-Step Instructions
Step 1: Prepare Your Kitchen
Preheat your oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or generously grease with butter. If using old-fashioned oats instead of pre-made oat flour, pulse them in a food processor for 30-60 seconds until they reach a fine, flour-like consistency.
Step 2: Mix the Dry Ingredients
In a large bowl, whisk together the oat flour, sugar, baking powder, salt, and cinnamon until well combined. This ensures even distribution of leavening agents and prevents lumps in your finished muffins.
Step 3: Prepare the Blueberries
Toss your blueberries with 1 tablespoon of flour in a small bowl. This coating prevents the berries from sinking to the bottom during baking and helps them distribute evenly throughout the muffins.
Step 4: Combine Wet Ingredients
In a separate medium bowl, whisk together the eggs, milk, melted butter, Greek yogurt, and vanilla extract until smooth. Make sure your melted butter isn’t too hot, as it could cook the eggs.
Step 5: Create the Batter
Pour the wet ingredients into the dry ingredients. Using a rubber spatula or wooden spoon, gently fold the mixture together just until combined. The batter should look slightly lumpy – overmixing leads to tough muffins.
Step 6: Fold in Blueberries
Gently fold the flour-coated blueberries into the batter with minimal mixing. You want to maintain those beautiful pockets of berries throughout each muffin.
Step 7: Fill and Bake
Divide the batter evenly among the 12 muffin cups, filling each about 2/3 full. Bake for 18-22 minutes, or until the tops are golden brown and a toothpick inserted into the center comes out with just a few moist crumbs.
Step 8: Cool and Enjoy
Allow muffins to cool in the pan for 5 minutes before transferring to a wire rack. This prevents them from becoming soggy on the bottom while ensuring they hold their shape.
What to Serve Blueberry Muffins Oat Flour With
These versatile muffins pair beautifully with both sweet and savory options:
Morning Companions: Serve warm with a pat of butter, cream cheese, or your favorite jam. They’re perfect alongside a cup of freshly brewed coffee or chai tea.
Breakfast Spread: Include them in a brunch spread with scrambled eggs, crispy bacon, and fresh fruit salad for a balanced meal.
Afternoon Treats: Pair with a glass of cold milk or herbal tea for an afternoon snack that satisfies without being overly heavy.
Dessert Options: Serve slightly warmed with a scoop of vanilla ice cream or a dollop of whipped cream for an elevated dessert experience.

Top Tips for Perfecting Blueberry Muffins Oat Flour
Don’t Overmix the Batter
The key to fluffy muffins is minimal mixing. Stir just until the ingredients are combined – lumps are your friend! Overmixed batter develops too much gluten, resulting in dense, tough muffins.
Use Room Temperature Ingredients
Room temperature eggs and milk blend more easily with other ingredients, creating a smoother batter and more even texture in your finished muffins.
Coat Your Berries
Always toss blueberries in a little flour before folding them in. This prevents them from sinking and creates better distribution throughout the muffin.
Check for Doneness Properly
Insert a toothpick into the center of a muffin – it should come out with a few moist crumbs, not completely clean. Completely clean means they’re overbaked.
Make Your Own Oat Flour
For the freshest flavor, grind your own oats in a food processor. It’s more economical and ensures you’re getting the finest texture possible.
Storing and Reheating Tips
Room Temperature Storage: Store cooled muffins in an airtight container at room temperature for up to 3 days. Place a paper towel in the bottom of the container to absorb excess moisture.
Refrigerator Storage: For longer freshness, refrigerate muffins in an airtight container for up to 1 week. This is especially important in humid climates.
Freezing Instructions: Wrap individual muffins in plastic wrap, then place in a freezer bag. They’ll stay fresh for up to 3 months. Thaw at room temperature for 2-3 hours.
Reheating Methods:
- Microwave: 15-20 seconds for room temperature muffins, 30-45 seconds for frozen
- Oven: Wrap in foil and warm at 350°F for 5-10 minutes
- Toaster: Cut in half and toast lightly for a crispy exterior

Frequently Asked Questions
Can I substitute the oat flour with regular flour?
Yes, you can substitute oat flour with all-purpose flour using a 1:1 ratio. However, you’ll lose the nutty flavor and added fiber that makes these muffins special. The texture will also be slightly different – less dense and chewy.
How do I make oat flour at home?
Simply pulse old-fashioned oats in a food processor for 30-60 seconds until they reach a fine, flour-like consistency. Let the processor rest for a minute before opening to allow the oat dust to settle.
Can I use frozen blueberries instead of fresh?
Absolutely! Don’t thaw frozen blueberries first – use them straight from the freezer. This prevents them from bleeding color into the batter and helps maintain the muffin’s appearance.
Why are my muffins dense instead of fluffy?
Dense muffins usually result from overmixing the batter or using ingredients that are too cold. Mix just until combined and ensure your eggs and milk are at room temperature for the best results.
How can I make these muffins dairy-free?
Replace the milk with your favorite non-dairy alternative (oat, almond, or soy milk work well), use coconut oil instead of butter, and substitute the Greek yogurt with applesauce or mashed banana.
Can I add other mix-ins besides blueberries?
Yes! Try raspberries, blackberries, chocolate chips, chopped nuts, or dried cranberries. Keep the total add-ins to about 1 cup to maintain the proper batter consistency.
How do I prevent the muffin tops from browning too quickly?
If your muffin tops are browning faster than the centers are cooking, reduce your oven temperature by 25°F and increase the baking time by 3-5 minutes.
What’s the best way to measure oat flour?
Spoon the oat flour into your measuring cup and level with a knife. Don’t pack it down. If you’re grinding your own oats, 1 cup of oats typically yields about 3/4 cup of oat flour.
Additional Helpful Tips for Success
Ingredient Quality Matters: Use fresh, plump blueberries for the best flavor. If using frozen, choose brands without added sugar or preservatives.
Muffin Tin Preparation: For easy removal, use paper liners or thoroughly grease your muffin tin. A light dusting of oat flour after greasing can provide extra insurance against sticking.
Altitude Adjustments: If baking at high altitude (above 3,000 feet), reduce baking powder by 1/4 teaspoon and increase liquid by 2-3 tablespoons for best results.
Flavor Variations: Add 1 teaspoon of lemon zest for bright, citrusy muffins, or try 1/2 teaspoon almond extract for a subtle nutty flavor that complements the oat flour beautifully.
Make-Ahead Tips: You can prepare the dry ingredients up to a week in advance and store in an airtight container. When ready to bake, simply add the wet ingredients and proceed with the recipe.
These blueberry muffins oat flour treats prove that healthy baking doesn’t require sacrificing flavor or texture. With their tender crumb, bursts of sweet berries, and wholesome ingredients, they’re destined to become a staple in your baking repertoire. Whether you’re meal prepping for the week or treating your family to a special weekend breakfast, these muffins deliver consistent, delicious results every single time.
