Preheat oven to 425°.
Combine dry ingredients in a bowl and whisk.
Cut the butter into bits and add to dry mixture, us a pastry cutter, a fork or your hands to work it into the flour mixture to form a crumb-like consistency.
Add about half an egg and 2½ Tablespoons of cream and stir with a fork until the dough holds together.
Turn the dough out a cutting board and knead together with your hands 10 or so times. Pat into a rectangle about ½ inch thick, make rounds using a biscuit cutter or cookie cutter. Makes about 7 biscuits.
Bake on a sprayed cake pan or baking sheet for 15 minutes, until very lightly browned. Allow to cool slightly before slicing open in half.
Meanwhile, make the homemade whipped cream. Using the remainder of a half pint of cream (so just under a cup), place in a bowl with the powdered sugar and vanilla and whisk. Take turns whisking if you have little helpers until you have whipped cream! You can also put it in a jar with a lid and shake it into whipped cream. You can, of course, use a mixer!
Slice the strawberries, you can add a pinch of sugar to them if you like.
To assemble, slice the shortcakes open like sandwiches, fill with whipped cream and strawberries, and more on top. Serve immediately and enjoy!
