Instructions
Prepare the Streusel Topping:
In a small bowl, whisk together ½ cup(70g) gluten-free flour¼ cup(50g) granulated sugar, ¼ cup(50g) light brown sugar, ½ teaspoon ground cinnamon, and ¼ teaspoon kosher salt.
Pour in 4 tablespoons(56g) unsalted butter that has been melted and slightly cooled and mix with a fork until crumbs form. Chill in the refrigerator while you make the batter.
Prepare the Muffin Batter:
Preheat the oven to 400°F. Line a 12-cup muffin tin with paper liners or grease with nonstick cooking spray.
In a small bowl, toss 9 oz(250g) mixed berries with 1 tablespoon of the 2 cups(280g) gluten-free flour blend. Set aside.
In a large bowl, whisk together the remaining gluten-free flour blend, 1 cup(200g) granulated sugar, 1 tablespoon(12g) baking powder, ½ teaspoon(2g) baking soda, and ½ teaspoon(3g) kosher salt.
In a medium bowl, whisk together ½ cup(120g) whole milk, 2(100g) large eggs, ½ cup(113g) vegetable oil, and ½ tablespoon(7g) vanilla extract until smooth.
Pour the wet ingredients into the dry ingredients and fold until just combined. Do not overmix.
Gently fold in the floured berries.
Assemble and Bake:
Use a cookie scoop or measuring cup to portion out the batter into the prepared muffin tin, filling each cup almost to the top.
Sprinkle the streusel topping evenly over each muffin.
Bake at 400°F for 15-17 minutes, until the tops are golden and a toothpick inserted between the berries comes out with a few moist crumbs.
Let the muffins cool in the tin for 5 minutes before transferring to a wire rack.
Notes
Gluten-Free Flour: I tested this recipe with Bob's Red Mill 1-to-1 Gluten-Free Baking Flour (blue bag), which already contains xanthan gum. I cannot verify other flour blends will work as I have not tested them.
Room Temperature Ingredients: Bring your eggs and milk to room temperature before mixing for a better rise and more even batter.
