Ingredients
For the Muffins:
- 1 ¾ cups all-purpose flour
- ½ cup granulated sugar
- ¼ cup brown sugar
- 2 tsp baking powder
- ½ tsp baking soda
- ½ tsp salt
- 1 tsp cinnamon
- ½ cup unsalted butter, melted
- ½ cup milk (or buttermilk for extra softness)
- 2 large eggs
- 1 tsp vanilla extract
- 1 ½ cups fresh blackberries (or frozen, thawed & drained)
For the Oatmeal Streusel:
- ½ cup old-fashioned rolled oats
- ¼ cup all-purpose flour
- ¼ cup brown sugar
- ½ tsp cinnamon
- ¼ cup unsalted butter, melted
Instructions
- Preheat the oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or lightly grease it.
- Prepare the streusel topping: In a small bowl, mix the oats, flour, brown sugar, cinnamon, and melted butter until crumbly. Set aside.
- Make the muffin batter: In a large bowl, whisk together flour, granulated sugar, brown sugar, baking powder, baking soda, salt, and cinnamon.
- In another bowl, whisk the melted butter, milk, eggs, and vanilla until well combined.
- Gently fold the wet ingredients into the dry ingredients, mixing just until combined. Do not overmix.
- Carefully fold in the blackberries, trying not to crush them.
- Fill the muffin tin: Divide the batter evenly among the muffin cups, filling each about ¾ full. Sprinkle the oatmeal streusel topping over each muffin.
- Bake for 18-22 minutes, or until a toothpick inserted in the center comes out clean.
- Cool & enjoy: Let muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
Notes
- If using frozen blackberries, do not thaw them completely to prevent excess moisture.
- For extra crunch, add chopped nuts like pecans or walnuts to the streusel.
- These muffins stay fresh in an airtight container at room temperature for up to 3 days or in the fridge for up to a week.
