Wash and dry the strawberries, remove the green and then cut into small pieces until you have 1 cup.
Spread the strawberries on a plate and then place in the freezer for about 20-30 minutes.*
Preheat the oven to 375 degrees.
In a large bowl, mix flour with baking powder. Put cubes of cold butter on top. Grind into small crumbs with your hands or a pastry cutter.
Measure 2 tbsp of the flour/butter mixture, and set aside for later.
In a small bowl, mix the sugar, vanilla, and egg.
Combine all ingredients in the large bowl. Then, add in the heavy cream.
Lastly, fold in the strawberries.
Spoon the batter into 9-10 muffin cups. You can use a muffin tin sprayed with cooking spray, or use muffin liners.
Take the reserved flour/butter mixture and mix with 1 extra tbsp of sugar. Sprinkle this on top the muffins before cooking.
Bake 20-25 minutes or until a toothpick comes out clean!
