Soak plank for 30 minutes in tepid water.
Toast almonds in a skillets, making sure to move them around often so they do not burn. This process will take about 3 minutes or so. Once they start to toast, it will go fast so keep a close eye on them. Remove almonds from heat and place onto a cutting board. Using a sharp knife, chop into smaller pieces. Set aside.
Preheat grill for medium heat.
Remove plank from water and dry off thoroughly with paper towels.
Unwrap brie wheels and place them on the plank. Set plank onto grill grate, close lid and let cheese warm through for about 7-10 minutes. Next, spoon about 1/2 to 1 tablespoon of preserves right on the top center of each brie. Top with almonds. Save some extra preserves and almonds to serve on the side. Let cheese continue to warm for about 2 more minutes.
Remove and serve with your chosen accompaniments. I recommend crostini, crackers, or sliced apples.
