Follow these step-by-step instructions to create a delectable dish that will impress your family and friends. The process is divided into two main parts: making the biscuits and preparing the beef gravy.

Making the Biscuits:

1. Preheat the Oven: Preheat your oven to 450°F (230°C) and line a baking sheet with parchment paper.
2. Mix Dry Ingredients: In a large mixing bowl, combine the flour, baking powder, baking soda, and salt.
3. Add the Butter: Using a pastry cutter or your fingers, cut the cold, cubed butter into the dry ingredients until the mixture resembles coarse crumbs.
4. Incorporate the Buttermilk: Gradually add the buttermilk, stirring until just combined. Be careful not to overmix, as this can result in tough biscuits.
5. Shape the Dough: Turn the dough out onto a floured surface and gently knead it a few times. Roll it out to about 1/2-inch thickness.
6. Cut the Biscuits: Use a biscuit cutter or a round glass to cut out biscuits and place them on the prepared baking sheet.
7. Bake the Biscuits: Bake for 10-12 minutes or until golden brown. Remove from the oven and let them cool slightly on a wire rack.

Preparing the Beef Gravy:

1. Cook the Ground Beef: In a large skillet over medium heat, cook the ground beef until browned, breaking it into small pieces with a spatula. Drain any excess fat.
2. Add the Flour: Sprinkle the flour over the cooked beef and stir to coat.
3. Pour in the Broth: Gradually add the beef broth, stirring constantly to prevent lumps from forming.
4. Stir in the Cream: Add the heavy cream and continue to stir until the gravy thickens.
5. Season the Gravy: Add the Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Adjust the seasoning to taste.
6. Simmer the Gravy: Reduce the heat to low and let the gravy simmer for 5 minutes, allowing the flavors to meld together.
