Preheat your conventional oven to 400 degrees Fahrenheit. Get a large mixing bowl, spatula and a whisk ready.
Mix in the baking powder and soda, flour, salt all into the mixing bowl. Mix it with the whisk so that everything is properly blended and not in clumps. Add the butter pieces to the mix as well at this point. Once you have consistency, it’s time to add in the buttermilks while stirring at the same time in a gentle motion. Use a spatula or spoon for this part of the job. Don’t pour it all in immediately. Instead, pour and mix repeatedly.
By this point, the dough has formed, and it can be poured out on to a workspace is already dusted with flour. Use a rolling pin to flatten the dough gently into a circle. The desired depth is about one inch of thickness.
With pre-designed biscuit cutter carve out the shapes of the biscuits from the dough. If you have leftover and can combine it into another biscuit, do so. Place each cut biscuit shape into a baking pan with enough room that the edges are just in contact with each other.
Insert the pan into the oven and bake for a maximum of 15 minutes (your time might vary a bit less depending on your oven). Ideally, the outside of the biscuits should be a light golden brown on the top part and lighter on the sides.
