Preheat the oven to 350°F and line a baking tray with parchment paper.

Drizzle the potatoes with olive oil. Use a fork to poke holes in them. Place the potatoes on the lined baking tray and bake for 1 hour or until a fork slides into them easily.

While the potatoes bake, fry the bacon in a hot skillet until it is completely crispy, the crispier the better. Use a knife or scissors to cut it up into small pieces. 

Once the potato is cooked and cool enough to handle, use a sharp knife to cut off the top third of the potato lengthwise. Scoop the inside of the baked potato out with a spoon and put it into a bowl. 

Using a potato masher or a fork, mash the potato until it’s smooth. Add in the butter, sour cream, milk, salt, and pepper.

Add the diced bacon, spring onion, and half the grated cheese into the bowl and combine.

Scoop the mashed potato mix back into the potato skins. Sprinkle on the potato the rest of the grated cheese. Set the oven to GRILL and place the potatoes inside for 2 – 3 minutes or until the cheese has melted.
