Step 1

Preheat the oven to 375 degrees Fahrenheit. Poke each sweet potato with a fork several times. Cook in the microwave individually for about 8 minutes each.

Step 2

Remove sweet potato skins by peeling them back, using a knife if needed.

Step 3

In the bowl of a stand mixer, add cooked sweet potato, 1/2 cup of brown sugar, 1 stick of melted butter, salt, and vanilla extract. Mix using the paddle attachment until smooth.

Step 4

In a separate bowl, add remaining stick of butter, flour, pecans, and remaining 1 cup of brown sugar.

Step 5

Pour sweet potato mixture into an 8x8-inch baking dish that has been sprayed with non-stick cooking spray. Spread evenly so the top is smooth. Sprinkle the streusel topping evenly on top. Bake for 15 minutes.
