Cook the bacon - but not too crispy. I like to line a plate with a lot of paper towel and line the bacon on it then add some more paper towel on top and cook in the microwave. About 4-5 minutes does the trick usually. Once cooked chop into small pieces.
Add the marshmallow fluff, evaporated milk, butter, brown sugar and salt to a pot and apply medium-high heat until boiling. Time it to boil that way for 5 minutes. Stir often with a whisk.
Remove from the heat and add the white chocolate chips. Stir in until melted.
Add the bacon pieces, chopped pecans and maple extract. Stir well until combined.
Line an 8x8" pan with foil and spray lightly with oil. Pour the fudge mixture into the pan and spread out evenly with a spatula.
Put into the refrigerator for at least 2 hours.
Once set cut into squares.
Notes
Try to find a bacon that is as lean as possible. Back bacon will work the best.
