These easy blueberry muffins have a crunchy crumb topping and the fluffiest texture ever! Studded with juicy blueberries, these bakery-style muffins are a delightful morning treat.


For the muffins:

  • 2 cups all-purpose flour
  • 2 teaspoons baking powder
  • 1/2 teaspoon kosher salt
  • 3/4 cup yogurt
  • 1 cup granulated sugar
  • 3 large eggs
  • 1 teaspoon vanilla extract
  • 3/4 cup olive oil
  • 2 cups fresh blueberries

For the streusel crumb topping:

  • 1/3 cup all-purpose flour
  • 3 tablespoons light brown sugar
  • 1 teaspoon cinnamon
  • 3 tablespoons unsalted butter, cut into small pieces


Prep your tools. Preheat oven to 350°F. Grease a muffin tin with the capacity for 12 muffins and set it aside.

Make the crumb topping. In a small bowl combine the streusel crumb topping ingredients. Use your fingers to work the butter into the dry ingredients until it resembles coarse breadcrumbs. Set aside. 

Mix the dry ingredients. In a large bowl, combine flour, baking powder, and salt.

Mix the wet ingredients. In a different bowl, whisk together yogurt, eggs, sugar, olive oil, and vanilla.

Combine. Add the dry ingredients to the wet ingredients and mix well until combined.

Add blueberries. Stir in the blueberries. 

Bake. Divide the batter among your muffin tins. Sprinkle the crumb topping onto each muffin. Bake for 30-35 minutes, until the muffins are golden brown and spring back when you gently press them with your fingertips.


Let your muffins come to room temperature, then place them in an airtight container and store them as follows.

  • Counter: They will keep for up to 3 days on the counter. You can also use a glass cake stand with a cover to store these.
  • Fridge: Place the container with the muffins in the fridge and store them for up to 7 days.
  • Freezer: Wrap each muffin in saran wrap before placing them in your airtight, freezer-safe container. They will keep for up to 3 months.
