1Whisk together the cake flour, all-purpose flour, sugar, baking powder, baking soda, and salt in a large bowl.
2Add in the cold and cubed butter, and use a pastry cutter or two knives to cut the butter into the flour mixture until it is crumbly and the butter resembles pea-sized chunks.
3Make a well in the center of the mixture, and pour in the buttermilk and sourdough discard.
4Mix with a wooden spoon until barely combined (it will still be crumbly).
5Use your hands to knead and fold the dough over itself a couple of times until combined.
6Add the blueberries, and gently fold a few more times until the blueberries are evenly dispersed.
7Use a very large cookie scoop or a ½ cup measuring cup to scoop the dough for each biscuit, and place in the prepared skillet or pan.
8Brush the tops of the biscuits with buttermilk or heavy cream.
9Sprinkle the tops with the cinnamon sugar mixture.
10Bake for 20-25 minutes, or until fluffy and golden brown.
11While baking, prepare the whipped salted vanilla bean butter. In a medium bowl, whip the butter and vanilla bean paste together with a whisk or handheld electric mixer until combined and fluffy. It will also turn slightly lighter in color.
12Remove the biscuits from the oven and serve warm with the whipped salted vanilla bean butter, honey, and flaky sea salt if desired.
