Step 1: Preheat the Oven

1. Preheat your oven to 375°F (190°C).

Step 2: Prepare the Muffin Tin

1. Lightly grease a standard muffin tin with cooking spray or oil to prevent sticking.

Step 3: Cook the Bacon

1. In a skillet over medium heat, cook the bacon until partially cooked but still pliable (about 5-7 minutes).
2. Remove the bacon and place on paper towels to drain excess fat.

Step 4: Form the Cups

1. Take one slice of bacon and place it around the inside of each muffin cup, forming a circle. Use one slice per cup or overlap two slices for a thicker base.

Step 5: Add Eggs

1. Carefully crack an egg into each bacon-lined muffin cup. Season with salt and pepper if desired.
2. Sprinkle any optional toppings on top of the eggs.

Step 6: Bake

1. Place the muffin tin in the oven and bake for 15-20 minutes, or until eggs are set to your liking. For runny yolks, check at around 12-15 minutes.

Step 7: Cool and Serve

1. Remove the muffin tin from the oven and let cool for a few minutes.
2. Run a knife around the edges to help release the cups, then gently lift them out.
3. Serve warm and enjoy your Bacon & Egg Cups.
