Description

Delight in these moist and flavorful Blackberry Muffins topped with a crunchy oatmeal streusel. Perfect for breakfast or a snack, these muffins combine fresh or frozen blackberries with a tender crumb and a buttery oat topping for a satisfying treat.


Ingredients

Scale

Muffin Batter

  • 2 cups all-purpose flour
  • 1 cup granulated sugar
  • 1/2 cup butter, melted
  • 2 large eggs
  • 1/2 cup milk
  • 1 teaspoon vanilla extract
  • 2 teaspoons baking powder
  • 1/2 teaspoon salt
  • 1 1/2 cups fresh or frozen blackberries

Oatmeal Streusel

  • 1/2 cup old-fashioned oats
  • 1/4 cup all-purpose flour
  • 1/4 cup brown sugar
  • 1/4 cup butter, cold and cubed


Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C) and line a muffin tin with paper liners to prepare for baking.
  2. Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, baking powder, and salt until evenly combined.
  3. Combine Wet Ingredients: In a separate bowl, mix the melted butter, eggs, milk, and vanilla extract thoroughly.
  4. Combine Batter: Add the wet ingredients to the dry ingredients and stir gently until just combined. Carefully fold in the blackberries to avoid breaking them.
  5. Prepare Streusel: In a small bowl, mix oats, flour, and brown sugar. Cut in the cold cubed butter with a pastry cutter or fingers until the mixture resembles coarse crumbs.
  6. Fill Muffin Tin: Spoon the batter into each muffin cup, filling about three-quarters full. Evenly sprinkle the oatmeal streusel over the tops of the batter-filled cups.
  7. Bake: Bake in the preheated oven for 20-25 minutes or until a toothpick inserted into the center of a muffin comes out clean.
  8. Cool: Allow the muffins to cool in the tin for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • Fresh blackberries are preferred but frozen blackberries can be used; just do not thaw before folding into the batter to prevent color bleeding.
  • Do not overmix the batter to keep muffins tender.
  • The streusel can be made ahead and stored in the refrigerator.
  • For a dairy-free version, substitute butter and milk with plant-based alternatives.
  • Store muffins in an airtight container at room temperature for up to 3 days or freeze for longer storage.
