Mixed Berry Muffins with Brown Sugar Streusel

Mixed Berry Muffin Recipe

  • Author: Rebecca Blackwell
  • Total Time: 45 minutes
  • Yield: 12


Moist and tender muffins, packed with berries and topped with buttery brown sugar streusel.



  • 3/4 cup brown sugar
  • 3/4 cup unbleached all-purpose flour
  • 3/4 tsp cinnamon
  • 1 tsp salt
  • 1/3 cup old fashioned oats
  • 6 tbsp butter, melted


  • 2 cups unbleached all-purpose flour
  • 2 tsp baking powder
  • ½ tsp salt
  • 4 tbsp butter, melted
  • 1/2 cup granulated sugar
  • 1/2 cup Stevia (see note)
  • 2 large eggs
  • 1¼ cup plain yogurt, full fat or 2%
  • 1 tbsp lemon zest
  • 1 tsp vanilla extract
  • 2 heaping cups fresh or frozen berries



  1. Combine all the dry ingredients in a small bowl. Pour in the melted butter and mix until all the dry ingredients are moistened. Cover, and set aside.


  1. Preheat oven to 375 degrees and line muffin pan with paper liners.
  2. Dump the flour, baking powder and salt into a medium size bowl and mix with a wire whisk to combine.
  3. Combine the melted butter, sugar, and Stevia in a medium size bowl and whisk vigorously with a wire whisk for about 30 seconds, until well combined. Add the eggs and whisk for another 30 seconds. Whisk in the yogurt, lemon zest and vanilla extract until combined.
  4. With a rubber spatula or wooden spoon, stir in the dry ingredients and then the berries. The batter will be very thick. If using fresh berries, fold them into the batter as gently as you can with a rubber spatula or wooden spoon. When mixing in frozen berries, I usually use my hands to fully incorporate them into the batter.
  5. If using tulip muffin liners, distribute the batter amongst 12 muffin cups. If using regular muffin liners, fill 18 - 24 muffin cups ½ full. The batter is very thick, so use your fingers or the back of a spoon to press the batter gently into each cup. Evenly distribute the crumb topping across all the muffins.
  6. If using tulip liners, bake for 28 - 32 minutes, until a toothpick inserted in the center of one of the muffins comes out mostly clean. If baking slightly smaller muffins in regular muffin liners, bake for 18 -23 minutes.
  7. Let cool on a wire rack.


  • If not using Stevia, increase the granulated sugar to 1 cup.
