Easy, Flaky, Buttery Biscuits

I have tried many of a biscuit recipe... I think this is the best one yet. 

3 cups Flour
4-½ teaspoons Baking Powder
2 Tablespoons Sugar
¾ teaspoons Cream Of Tartar
½ teaspoons Salt
¾ cups Butter, Cold
1 whole Egg, Slightly Beaten
1 cup Milk

Preheat oven to 450 degrees.
Mix dry ingredients together.
Cut in cold butter, until it is pea-sized.
Mix egg and milk, pour into the dry mix.
Stir together with a fork.
Combine all the dry mix with the wet mixture until it forms a soft ball.
Turn out onto a floured counter.
Pat down until 3/4″ thick (rolling will keep it from being flaky).
Using a biscuit cutter (or whatever you have handy), cut biscuits out and place on an ungreased pan.
Bake for 10-12 minutes until golden and beautiful.


note: I have always laid my dough out into a rectangle and cut out square biscuits. It just seems like effective use of time and dough.
