Preheat oven to 425°F and line a baking sheet with parchment paper.
In a large bowl, whisk the flour, baking powder, sugar, and sea salt together.
Using a pastry cutter or the back of a fork, cut the cold butter in until the mixture looks nice and crumbly.
Add the cream and vanilla and stir until just combined.
Using a 4 TBS cookie scoop, scoop dough into mounds, evenly spaced on the baking sheet. There's no need to roll or shape these, craggy tops are perfect here.
Bake biscuits for 12–14 minutes until golden on top. Let cool slightly.
Notes
Use very cold butter for the best texture.
Don’t overmix the dough. It should be a little rough.
For savory use, you can leave out the vanilla.
If the dough feels too dry, add a splash of cream to help it come together.
If you substitute milk for heavy cream, the biscuits will be lighter, slightly less rich, and also less tender.
