Do not over mix.Fold in Flavourings, including cooked bacon..Place 3 tbsp of the batter into 4 muffin tin holes. Bang the tin to flatten the batter.Make a divot in the batter (so the egg yolk settles in the middle). Crack an egg into each hole. Divide the remaining batter between each hole to cover the egg.
