This is a fun recipe to make with a group of kids in a classroom or at a birthday party. Little kids can mix the sugar with the berries, whisk the dry ingredients together, cut out and arrange the biscuits, shake the cream and build shortcakes. Bigger kids can do all parts of this recipe, except putting the cakes into and removing them from the oven.
A 2-inch biscuit cutter and a sealable plastic container (at least 1 quart) for making whipped cream
Make the strawberries first: Mix the sliced strawberries with the sugar and a squeeze of lemon in a large bowl. Set them aside, stirring a few times, until they are nice and juicy, about 30 minutes.
Make the biscuits: Preheat the oven to 425 degrees F. Whisk together the flour, sugar, baking powder and salt in a large bowl. Add the cream. Add the lemon zest and juice. Stir the mixture with a wooden spoon until it just forms a dough. Gather the dough into a ball and transfer it to a flour-sprinkled surface. Pat it into a 1/2-inch-thick circle. Cut as many mini biscuits as you can with a 2-inch biscuit cutter. Gently press the scraps together and repeat. Arrange the rounds 1 inch apart on 2 parchment-lined baking sheets. Brush them with more cream and sprinkle with a little sugar. Bake them in the middle of the oven until they are just golden, about 12 minutes. Cool the biscuits while you make the whipped cream.
Make the whipped cream: Combine the cream with the sugar and vanilla in a sealable container. Whisk or shake with the lid on until soft peaks form.
To serve: Split the biscuits with a fork and spoon some juicy strawberries and whipped cream on the bottom halves of the biscuits. Place the top halves on top. Add more whipped cream and a mint leaf to each, if using.
