Using a small saucepan, melt butter over medium heat. Add all three sugars and pumpkin spice. Mix to combine.
Remove from heat and add vanilla, lemon, and coconut.
Pour mixture all over sliced yams to coat. Cover with foil and roast for 60-70 minutes or until tender. Remove from the oven and baste with mixture.
Place yams back into oven and roast for another 20 minutes uncovered. Remove from the oven and allow to sit for about 10 minutes before serving. Say Grace and enjoy!!
