Preheat the oven to 325°F. Line a baking sheet with parchment paper.
In a medium bowl, stir together flour, walnuts, brown sugar, and salt. Mix in Vanilla Fudge Butter Snack Spread with fingertips until fully combined. Break into small crumbles and arrange in an even layer on one side of the sheet pan.
Use a paring knife to cut off the top rind of the Brie, leaving a ¼-inch border around the edges (cut away the rind from above at a slight angle). Discard the rind and put the Brie in a small baking dish.
Spread surface of the cheese with apricot preserves and cover with foil. Place on the other side of the baking sheet and bake for 30-35 minutes or until cheese is completely melted and the crumble is golden brown.
Sprinkle crumbles all over the surface of the baked brie and serve with sliced baguette, crackers, sliced apples.
