Preheat the oven to 400℉ and line a baking sheet with parchment paper. In a small pitcher or bowl, whisk the coconut milk and lemon juice together. Set it aside and let it sit for about 5 minutes to thicken. This mixture will serve as a buttermilk-style substitute for your shortcake biscuit dough!
In a medium bowl, sprinkle the sliced strawberries with 2 tbsp of cane sugar, then stir to combine. Set them aside while you finish the biscuit dough, as the berries will become juicier after a bit of time!
Combine the all purpose flour, almond flour, cane sugar, baking powder, and cornstarch in a bowl. Whisk to incorporate.
Add the coconut oil and use a pastry cutter or spatula--or use your hands if you like!--to work it into the flour until the mixture takes on a sandy consistency. A mixture of small lumps and larger lumps here is a good thing! Add the coconut milk + lemon juice mixture you prepared earlier and use a spatula to fold it in.
Keep stirring and folding just until the dough comes together. I find at a certain point, it’s easiest to use your hands here.
Transfer the dough onto a floured board or clean countertop flatten it with clean hands or a rolling pin. Aim for an overall thickness of about ½-inch. Using a flour-dusted cookie cutter or the rim of a glass, cut out six circles and place them onto the baking sheet, arranging them so that they touch each other.
Transfer your biscuits to the preheated oven and bake until risen and slightly golden brown, about 18 minutes. Cool the biscuits completely before you separate them, then use a serrated knife to slice them each in half along their equator.
Place a spoonful of strawberries and juice on the bottom half of each biscuit. Top the berries with a dollop–or two, if you’re like me!--of whipped coconut cream and place the top half of the biscuit on each.
