First, preheat oven to 400ºF and spray a baking sheet with nonstick cooking spray.
Then, prepare Brussels sprouts by washing, patting dry, and halving the longway.
Place Brussels sprouts on a large baking sheet, drizzle with olive oil, and toss.
Then, season with garlic powder, salt, and, pepper, and toss again.
Bake at 400ºF for 20 minutes.
While the Brussels sprouts are roasting, mix together apple butter and maple syrup and set aside.
Once your Brussels sprouts have cooked for 20 minutes, remove them from the oven and spoon on 3 tablespoons of the apple butter mixture. Toss to make sure everything is fully coated.
Then, move the brussels sprouts to one side of the pan and spray the other side with nonstick cooking spray. Add the raw pecans.
Toss the pecans in the remaining apple butter mixture. Spread pecans out evenly so none of them are overlapping.
Roast at 400ºF for another 10 to 15 minutes.
