Slice the strawberries. Mix half of the sliced strawberries with 1/4 cup brown sugar & the lemon zest. Mash with a fork. Add rest of strawberries and mix gently to combine. Cover and set aside to rest. The flavours will deepen while it rests and you make the shortcakes.
Preheat oven to 400F
Sift together - flour, sugar, salt, baking powder.
Add 3/4 of the butter, mix to combine. Do not over mix. Add 1 1/4 cup cream. Mix to a soft dough. If it is looking too dry/not coming together add cold water a tsp at a time and knead till it starts coming together.
Turn into a clean floured counter and knead for 1 min. Roll out to about 1/2 inch thick. Cut using a 3 in biscuit cutter or an upside down glass. There should be an even number of circles. Total about 24 circles.
Grease the baking pan and place half the rounds on the pan. Leaving about 1-2 inches space between each. Melt remaining butter and brush the tops of each round. Top with the remaining rounds. You will have about 12 shortcakes in total.
Bake 10-15 mins or till golden brown.
Meanwhile whip the remaining cream with vanilla till stiff peaks form. Set aside.
When the shortcakes come out of the oven. Allow to cool 5 mins. Split in half and place the bottom half on a plate. Spread with more melted butter, Top with a dollop of whipped cream and a spoon of the prepared strawberry mixture. Top with the second half of the shortcake, more cream and strawberries. Top with a sprinkle of finely chopped basil, if you like.
Serve immediately while the shortcake is till warm.
Shortcakes can be frozen after baking. Warm them up just before serving. Great for breakfast with coffee or chai!
