Preheat oven to 350 degrees and spray a large baking sheet with non-stick cooking spray.
In a medium bowl, add the ground beef, 1 egg, breadcrumbs, mustard, ketchup, 1 teaspoon garlic powder, onion powder, and Worcestershire sauce. Mix all ingredients until well blended.
Place the block of cheese on a cutting board. This recipe makes 16 Cheeseburger Biscuit Bombs. Cut the block into 16 even slices, then cut the slices in half. You will have a total of 32 pieces of cheese.
Separate the meat mixture into 16 pieces. Take a ball of meat and flatten it either in your hand or on a clean counter. Place two pieces of cheese in the center of the flattened meat. Bring the meat up and over the cheese to surround the cheese completely. Roll the stuffed meatball in your hand to firm the meat and seal any area where cheese may be showing. Repeat this step with all pieces of meat and cheese.
Place stuffed meatballs on prepared baking sheet and bake for 15 to 20 minutes, or until meat is cooked through. Remove meat from oven and scrape away any cheese that has seeped onto the baking sheet. Escaping cheese is normal. Allow meat to cool before wrapping it in biscuit dough.
Reduce oven temperature and preheat oven for the biscuits. If using a dark colored baking sheet, set temperature to 375 degrees. If using a light colored nonstick baking sheet, set temperature to 350 degrees.
Remove biscuits from the can and cut each round in half. Take a biscuit half and bring ends together to form a circle. Flatten the circle until it's wide enough to wrap around a meatball. Place a stuffed meatball in the center of the circle. Bring sides of dough up and around the meatball and pinch lightly at the top to seal. Next, smooth out the pinched dough and smooth out the wrapped meatball, closing any gaps that may be present. Repeat this process with the rest of the meatballs.
Place meatball stuffed biscuits on a baking sheet that has been sprayed with non-stick cooking spray.
In a small bowl prepare the egg wash. Mix 1 egg white, water, 1/2 teaspoon garlic powder, and parsley until well blended. Brush each biscuit with the egg white wash. Bake biscuits for 18 to 20 minutes, or until tops of biscuits are golden brown. Be careful to not burn the bottom of the biscuits.
Notes
Helpful Tips:These amazing little treats are scrumptious right out of the oven (watch out for that hot gooey cheese!), or reheated in the microwave. You can prepare the stuffed meatballs (cheese inside meat only) up to 2 days in advance and do the baking of the meatballs and biscuits the day of your event.
