- Prepare the Strawberries: In a medium bowl, combine the sliced strawberries, sugar, and lemon juice (if using). Stir gently and let macerate at room temperature for at least 30 minutes, or up to 2 hours, stirring occasionally. 
- Make the Shortcake Dough: Preheat oven to 400F (200C). In a large bowl, whisk together the flour, sugar, baking powder, and salt. 
- Cut in the Butter: Add the cold, cubed vegan butter to the dry ingredients. Use a pastry blender or your fingertips to cut the butter into the flour mixture until it resembles coarse crumbs. 
- Add Wet Ingredients: In a separate small bowl, combine the plant-based milk and vanilla extract. Pour the wet ingredients into the dry ingredients and stir until just combined. Do not overmix. 
- Shape the Shortcakes: Drop spoonfuls of dough (about 1/2 cup each) onto a baking sheet lined with parchment paper. 
- Bake the Shortcakes: Bake for 18-22 minutes, or until golden brown. Let cool on a wire rack. 
- Prepare the Vegan Whipped Cream: Carefully scoop out the thick coconut cream from the top of the refrigerated coconut milk cans, leaving the watery liquid behind. Place the coconut cream in a chilled bowl. 
- Whip the Cream: Add the powdered sugar and vanilla extract to the coconut cream. Use an electric mixer to whip the cream until light and fluffy, about 3-5 minutes. 
- Assemble the Shortcakes: Split each shortcake in half. Spoon a generous amount of macerated strawberries and their juices over the bottom half of each shortcake. Top with a dollop of vegan whipped cream and the top half of the shortcake. Serve immediately. 
- Tips and Substitutions: 
- For a richer shortcake, use coconut oil instead of vegan butter, but make sure it's solid. 
- Maple syrup or agave nectar can substitute granulated sugar in the shortcakes or macerated strawberries. 
- Store-bought vegan whipped topping can be used for convenience.
