Whisk together flour, salt, baking soda and baking powder in a large bowl. Cut cold butter into flour mixture until it resembles coarse crumbs. I shred my butter with a hand shredder but you could cut it in small pieces. I just use a large spoon to cut the butter into the flour.

Stir in the French onion dip and buttermilk with a spoon until it comes together with the flour. Sprinkle some flour onto a counter top or board, pat out with your hands to about 1/2 inch thick. Cut out biscuits with a biscuit cutter. (You can use an empty metal can or a glass, too.) Place on a sprayed baking sheet and bake in preheated 425 degree oven for 12 to 15 minutes until tops are golden brown.
