Ingredients

Streusel Crumble Topping

  • 1/4 cup salted butter, melted
  • 1/2 cup all-purpose flour
  • 1/2 cup granulated sugar
  • 1/8 teaspoon ground cinnamon
  • 1 pinch salt

Muffin Batter

  • 1-3/4 cups all-purpose flour
  • 1/2 cup granulated sugar
  • 3 teaspoons baking powder
  • 3/4 teaspoon salt
  • 1 large egg, beaten
  • 1/3 cup canola oil
  • 3/4 cup milk
  • 1-1/2 cups fresh blackberries, rinsed and larger berries halved (or frozen blackberries)

Instructions

  1. Preparation: Preheat the oven to 375°F (190°C). Line a muffin or cupcake pan with paper liners and set aside. Rinse the blackberries and cut larger ones in half, then dry on a paper towel-lined plate.
  2. Make Streusel Crumble Topping: In a small bowl, combine melted butter, flour, sugar, cinnamon, and salt. Use a fork or spoon to cut the butter into the mixture until small crumbs form, avoiding overmixing. Cover with plastic wrap and refrigerate until ready to use.
  3. Prepare Dry Ingredients: In a medium bowl, whisk together the flour, sugar, baking powder, and salt.
  4. Make Muffin Batter: Add milk, canola oil, and beaten egg to the dry ingredients. Stir gently with a large spoon until just combined; do not overmix to keep muffins tender.
  5. Fold in Blackberries: Using a spatula, gently fold the prepared blackberries into the batter.
  6. Fill Muffin Liners: Evenly distribute the batter into each paper-lined muffin cup in the baking pan.
  7. Add Streusel Topping: Sprinkle the crumble topping evenly over each muffin.
  8. Bake: Bake in the preheated oven at 375°F (190°C) for about 20-21 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
  9. Cool: Remove muffins from the oven and transfer to a cooling rack. Let them cool before serving.
  10. Serve: Enjoy muffins warm, at room temperature, or chilled according to preference.

Notes

  • Using fresh blackberries is ideal, but frozen can be substituted; thaw and drain well before adding.
  • Do not overmix the batter to avoid dense muffins.
  • The crumble topping can be made ahead and stored refrigerated.
  • Check muffins a few minutes before the baking time ends, as oven temperatures vary.
  • Store muffins in an airtight container at room temperature for up to 2 days or refrigerate for longer freshness.
