Preheat the oven to 350°F. Line 18 muffin tins with cupcake liners. Set aside.
Sift together 2 cups of the flour, 1 teaspoon baking powder and 1 teaspoon salt in a mixing bowl, set aside.
In a small bowl, toss together the remaining 2 tablespoons of flour and 2 tablespoons of the sugar with the chopped 2 cups fresh strawberries . Set aside.
In a stand mixer fitted with the paddle attachment or a large mixing bowl with an electric mixer, blend together the melted 1/2 cup unsalted butter, remaining sugar, 3/4 cup milk , 1 egg and1 teaspoon vanilla extract.
Slowly add the dry ingredients to the batter. Do not over mix. Stop when it is combined, but there are still small lumps.
Fold in the strawberries, including any excess flour or sugar in the bowl, by hand. The batter will marbleize or turn blue if using frozen strawberries.
Cheesecake Filling:
In a medium mixing bowl or the bowl of a stand mixer fitted with the paddle attachment, beat the softened 4 ounces cream cheese until smooth.
Add the 1 egg and 1 teaspoon vanilla extract , mix. Blend in the 3 tablespoons sugar and 1 tablespoon flour, mix well for 2-3 minutes. Set aside.
Streusel Topping:
Use a cheese grater and grate cold 1/4 cup unsalted butter into a bowl. Cut in the 2 tablespoons brown sugar, 2 tablespoons sugar, 1/2 cup flour and 1/4 teaspoon fine sea salt .
Assemble the Muffins:
Spoon 1 heaping tablespoon of muffin batter in each lined muffin tin. Add a little less than 1 tablespoon cheesecake mixture to each. Top with more muffin batter until approximately 2/3 full. Sprinkle the tops evenly with streusel mixture, pressing it ever so gently down to make it stick.
Bake the muffins for 25 minutes or until they are lightly browned. Times may vary based on oven and how much you filled those cups (I know a few of you took some chances and filled them to the brim, didn't you??). Muffin tops will spring back to the touch.
Remove from the oven and allow to cool.
