Preheat the oven to 425 degrees Fahrenheit.
Line a 12 cavity muffin tin with liners and set aside. I used these tulip liners to get the muffins big and tall. In a mixing bowl, whisk together all wet ingredients until smooth.
1/2 cup unsalted butter, 3/4 cup white sugar, 2 eggs, 3/4 cup milk, 2/3 cup greek yogurt, 1 teaspoon vanilla bean paste
Add in the flour, baking powder, baking soda and salt.
2 1/2 cups gluten free all purpose baking flour, 1 tablespoon cornstarch, 3 teaspoon baking powder, 1/4 teaspoon baking soda, 1/2 teaspoon salt
Whisk to combine.
Toss the diced strawberries with the 1 tablespoon of flour.
1 cup strawberries , 1 tablespoon gluten free all purpose baking flour
Add the strawberries to the batter and mix to combine.
Let set while we prep the streusel. Combine the melted butter, sugar and flour. Mix to combine.
1 tablespoon butter, 2 tablespoons brown sugar, 3 tablespoons gluten free all purpose baking flour
Scoop the batter into the prepared muffin tin. Add the streusel evenly on top.
Bake at 425 for 5 minutes, then decrease the temperature to 350 and bake an additional 16- 20 minutes or until a toothpick comes out clean.
Let cool in the muffin tin for about 10-15 minutes, then remove and let cool on a wire rack. Enjoy!
