Preheat your oven to 350 degrees F.
Place diced butter cubes in the freezer while you prepare the rest of your ingredients. You want the butter to be as cold as possible, at least 5 minutes.
In a medium sized mixing bowl place dry ingredients (flour, salt, and baking soda) and whisk together to combine. Prepare your buttermilk in a measuring cup.
Add in your cubed butter and work together with your hands or pastry cutter. Only do this until the consistency has pea sized pieces of butter with a few large pieces still intact.
Pour in your buttermilk and mix together with a fork or your hands. Be careful not to overmix.
Add the blueberries mixing them in with your hands so they don’t burst.
Pat dough out on a floured surface with your hands (A rolling pin may burst blueberries) into a 1-inch-thick rectangle.
Cut 8 biscuits out with a 2-inch biscuit cutter.
Place on a parchment paper baking sheet and into the freezer for 10 minutes.
Take out of the freezer and bake for 15-20 minutes.
While the biscuits are baking you can make the glaze. In a mixing bowl mix together cream cheese, powdered sugar, vanilla, and milk with a hand mixer. Combine until the glaze is smooth.
Allow baked biscuits to cool for ten minutes. You do not want the glaze to melt on top of the biscuits. Once they are cooled, drizzle glaze over biscuits before serving. Enjoy!
