Prepare the Crostini: Slice the baguette into ½-inch thick pieces and arrange them on a baking sheet. Preheat your oven to 400°F (200°C) and lightly brush each slice with olive oil. Bake for 5-7 minutes, or until golden and crisp.

Assemble the Savory Toppings: Once the crostini are cooled slightly, spread a generous layer of pesto on each slice. Cut cherry tomatoes in half and place them on top of the pesto. Cut mozzarella cheese into ghost shapes and press onto the tomatoes.

Create Spooky Eyeballs: Slice black olives into thin rounds and place them on top of the mozzarella cheese ghosts. Use toothpicks if needed to secure them in place.

Garnish and Serve: Add fresh basil leaves on top and arrange on a festive platter. Drizzle with olive oil for extra shine.

Optional Sweet Version: Mix cream cheese with powdered sugar until smooth. Spread on alternating crostini and sprinkle crushed candies on top.
