We love these for a yummy and nutritious breakfast on the go. If you feel so inclined, you can sub 1 pound of cooked sausage for the bacon and bacon bits, but I would recommend using silicone baking cups or a 9x13 glass pan coated with non-stick spray instead of a muffin tin if you go that route.
Preheat oven to 350. Lightly brown the bacon (do not fully cook). Set aside to drain. Pat with a paper towel to remove excess grease. Cut one piece of bacon into quarters. Use two half pieces on the bottom and one whole piece to go around each cup on a 12 muffin tin.
Add half a bag of bacon bits and 1 Tbsp of bacon drippings to the remaining egg mixture and stir well. Fill each cup on a 6 muffin tin (do not grease or line), or use silicone baking cups if able. Bake for 25 minutes. Serve immediately or allow to cool and refrigerate or freeze.
