Place a sweet potato in the microwave and cook for 6 minutes.
Test potato for doneness. It should be soft enough to eat.
Cut the potato in half. Place cut side up on a microwaveable plate.
Create hatch marks on potato. Spread to open.
Add butter and brown sugar to each half allowing it to get down in the cracks.
Place mini marshmallows on top then pecans.
Microwave for 30 seconds. Check to see if marshmallows are melted. If not, continue in 15 second intervals until the marshmallows have spread out and do not look like distinct little balls.
