In the bowl of a stand mixer, combine 5 cups of cottage cheese with 4 cups of self-rising flour.
Using your paddle attachment, set the mixer to low speed and mix until mostly combined.
Once the dough is mostly combined, begin adding the fifth cup of self-rising flour bit by bit while the mixer is running. Once all of the flour is added, continue mixing until the dough is well combined. It will be sticky, but you should be able to manipulate the dough without only a little excess sticking to your hands.
Spoon the dough onto a greased cutting board in 1-2 tbsp balls. If you have a cookie scoop, it would work well for this.
Bake the biscuits for 20-25 minutes. If after 20 minutes you notice the biscuits are not evenly browning, turn the trays around in the oven and cook for another 5 minutes.
The biscuits will be lightly browned on top. Test for doneness by inserting a toothpick into the thickest part of the biscuit. It should come out clean when biscuits are done.
