Preheat the oven to 350°. Line muffin tins with paper liners.
In a large bowl sift the flour, sugar, baking powder, baking soda, salt, and cinnamon. Mix to combine.
In a separate medium bowl, mix together the milk, butter, eggs, and vanilla extract.
Create a hole in the center of the dry ingredients. Pour the wet ingredients into the dry ingredients and mix with a fork just until combined. The batter will be lumpy.
Fold the strawberries into the mix - careful not to over mix.
For the streusel topping, combine the flour, sugar, cinnamon, and salt in a medium bowl. Add the cold butter and use a fork to cut the butter into the flour mixture until the texture is crumbly.
Scoop the muffin mixture into the muffin tins using an ice cream scoop or large cookie scoop. Fill the muffin cups so that they are almost full.
Sprinkle the streusel topping over the muffin batter.
Bake the muffins for about 20-25 minutes, until golden brown and cooked through.
