In a large bowl, combine all purpose flour, diced chives, garlic powder, onion powder, smoked paprika, sugar, baking powder, and kosher salt. Whisk together. 3 cups All Purpose Flour 2 tbsp Fresh Chives1 tbsp Garlic Powder1 tbsp Onion Powder1/2 tsp Smoked Paprika1 tbsp Sugar1 1/2 tbsp Baking Powder1 1/2 tsp Kosher Salt
Grate the butter with a box grater (or cut into small 1/2 inch pieces) and add it to the flour mixture. Pinch and turn the butter into the flour together until pea sized morsels form. (when you can squeeze everything together and it holds shape in your hand, you're ready to proceed) You can also use a pastry cutter or food processor to do this. 3/4 cup Salted Butter
Then add shredded cheddar cheese and parmesan. Toss together to evenly distribute. Whisk together buttermilk and egg in a small cup and then pour into the dry ingredients. 1 1/2 cups Sharp Cheddar Cheese1/3 cups Parmesan3/4 cup + 1 tbsp Buttermilk1 large Egg
Mix together until the dough comes together - it may look shaggy/crumbly at first, but it will come together after mixing for about 1 minute. Do not add more buttermilk!
Once the dough is combined, use a 1/4 cup measuring cup to scoop out the biscuit dough. Gently press together to form a circular shape, then place onto a baking sheet. Repeat with remaining dough.
Freeze the dough for 30 minutes.
Preheat the oven to 400 degrees F.
Once preheated, bake for 18-22 minutes on the middle rack, until the tops of the biscuits are golden brown.
Mix together the garlic butter ingredients and brush on top of the warm biscuits fresh out of the oven. 4 tbsp Salted Butter1/2 tsp Old Bay Seasoning 2 cloves Garlic2 tsp Parsley
