Ingredients

• 1 cup Old-fashioned rolled oats
• 1 cup All-purpose flour
• 0.25 cup Ground flaxseed
• 0.5 cup Brown sugar
• 2 teaspoons Baking powder
• 0.5 teaspoon Baking soda
• 1 teaspoon Cinnamon
• 0.25 teaspoon Salt
• 1 cup Buttermilk
• 1 Egg
• 0.25 cup Melted unsalted butter
• 1 teaspoon Vanilla extract
• 1 cup Fresh or frozen blueberries

Directions

Step 1

Preheat your oven to 400°F (200°C) and line a standard 12-cup muffin tin with paper liners or lightly grease it with cooking spray.

Step 2

In a large mixing bowl, combine the rolled oats, all-purpose flour, ground flaxseed, brown sugar, baking powder, baking soda, cinnamon, and salt. Stir well to ensure all dry ingredients are evenly mixed.

Step 3

In a medium bowl, whisk together the buttermilk, egg, melted butter, and vanilla extract until smooth.

Step 4

Pour the wet ingredients into the bowl of dry ingredients. Using a spatula or wooden spoon, gently fold the mixture until just combined. Avoid overmixing as it can result in dense muffins.

Step 5

Gently fold in the blueberries, being careful not to crush them. If using frozen blueberries, no need to thaw them beforehand.

Step 6

Divide the batter evenly among the prepared muffin tin cups, filling each about 3/4 full.

Step 7

Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center of a muffin comes out clean.

Step 8

Remove the muffins from the oven and let them cool in the pan for 5 minutes. Transfer them to a wire rack to cool completely.

Step 9

Serve warm or at room temperature. Store any leftovers in an airtight container at room temperature for up to 2 days, or freeze for longer storage.
