Start with 4 large sweet potatoes, just look at those beauties! After you dice and boil them for 20 minutes, you mash them and add all the good stuff...
To make the streusel topping, mix the flour, brown sugar, salt, and cinnamon together, then "cut" the butter in with a pastry utensil. Next stir in the pecans and marshmallows. When you spread it on top of the sweet potatoes, add some more marshmallows for good measure. It's the right thing to do!
Mmmmm, just look at that pan full of yumminess!
