Preheat oven to 375°F (190°C). Line a baking sheet with foil and place a wire rack on top.
In a bowl, mix together the brown sugar, water, black pepper, cayenne, and red pepper flakes until a thick paste forms.
Dredge each bacon strip through the sugar-spice mixture, pressing firmly to coat both sides. Lay strips on the wire rack with space between each piece.
Bake for 25–30 minutes, flipping carefully at the 15-minute mark, until dark, caramelized, and crispy. Let cool completely on the rack, then break into bite-size pieces.
Slice baguette into 24 rounds on a diagonal. Arrange on a baking sheet, brush with olive oil, and season with salt and pepper. Bake at 375°F for 8–10 minutes, flipping once, until golden and crisp. Optional: rub a peeled garlic clove over the warm toast.
Spread goat cheese generously onto each crostini. Top with candied bacon pieces. Drizzle with honey, maple syrup, or hot honey. Garnish with fresh thyme, chives, or candied pecans if desired.
Serve immediately for best texture.
