Mix the flour, baking powder, and salt until it's combined.
Add the cream. You may need more or less cream depending on what grain you are using and if it's 100% whole grain or if the bran has been removed to make all-purpose flour.
Using a dough whisk, combine until it's clumpy. You will still have some dry flour.
Using your hands, pull the dough together to create disk of dough.
Using a floured or oiled surface, place the disk of dough down and roll it out to be about 3/4" of an inch thick. You can make your biscuits thinner or thicker depending on your personal preference.
Using a biscuit cutter (or cookie cutter), cut out your biscuits. Keep gathering and rolling out your scrap dough until you've used as much of the dough as you can.
For the last bit of dough, called a "cathead" biscuit, push the dough down into your biscuit cutter, pulling the dough out to create a biscuit. This way you use cup all your dough.
Place your cut biscuits on a greased cookie sheet or cast iron skillet.
Bake at 350 degrees for 18-20 minutes or until slightly browned.
