Pre-heat oven to 400*F.
Line a baking sheet with parchment and spray/grease the parchment with oil.
Combine all dry ingredients in a large bowl.
Grate in the butter, cheese and then add the rest of the wet ingredients.
Stir to combine and then add in the bacon as well.
Use your hands to form the somewhat crumbly mixture into a ball.
Place the ball on the lined baking sheet and flatten to just over an inch or so thick.
Brush the dough with heavy cream(optional, helps browning) and then slice into 4-6 small pieces.
Separate the pieces slightly and bake for 20-25min or until the scones are browned to your liking.
Serve hot. Enjoy your keto bacon cheddar onion scones!
