• Place Sweet Potatoes chunks in a large pot and cover with water. Bring to a boil and cook until Potatoes are soft and knife inserted easily goes through.
• Drain and place in large bowl.
• Preheat oven to 350F.
• Add Sugar, Vanilla and Butter, and give it a stir. Now add in Eggs and using mixer, blend well until fluffy.
• Put Sweet Potato mixture into at least a 2 quart baking dish.
• To make the topping, mix together the Light Brown Sugar, Flour, melted Butter and Pecans until well mixed and butter has been "absorbed" and you now have a "crumble" mixture.
• Sprinkle over the top of the Sweet Potato mixture to cover completely.
• Place in 350F preheated oven, uncovered and bake for about 30 minutes or the crumble on top starts to turn golden.
• Remove from oven and cool for at least 5 minutes before serving.
• Serve and ENJOY!

If you want to add some scattered Marshmallows over top and let them brown, do so during the last 10 minutes of baking.
