Preheat oven to 350° Fahrenheit. Poke holes all around sweet potatoes with a fork then transfer to a baking sheet and bake for 1 hour or until very soft. Remove from the oven and let cool before transferring the flesh to a large bowl.
Mash sweet potatoes until smooth then add in the butter, eggs, brown sugar, sugar, milk, and vanilla extract. Beat with either a hand or stand mixer until smooth.
Transfer soufflé to a 9×13-inch baking dish then assemble the topping by mixing all topping ingredients together in a bowl. Sprinkle topping over top of soufflé.
Bake for 30-40 minutes or until golden brown.
Enjoy!
