Make the Batter: In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt. In another bowl, beat the eggs, then whisk in the milk, melted butter, and vanilla extract. Pour the wet ingredients into the dry ingredients and stir until just combined. A few lumps are okay; do not overmix.

Prepare for Decorating: Transfer roughly ½ cup of the plain batter to a small bowl. Mix in the melted chocolate chips and milk to create a thin, pipeable chocolate batter. Pour this into a squeeze bottle or a zip-top bag with a tiny corner snipped off.

Cook the Pancakes: Heat a non-stick griddle or pan over medium heat. Lightly grease with butter or oil. For each pancake, pour about ¼ cup of the plain batter onto the griddle, spacing them apart.

Create the Designs:

• Jack-o’-Lanterns: Cook plain circular pancakes. Once plated, use the chocolate bottle to draw triangle eyes and a jagged mouth while the pancake is still warm.

• Spider Webs: Pour a small circle of plain batter. Immediately pipe concentric circles of chocolate batter on top. Drag a toothpick from the center outward through the circles 6-8 times to create a web.

• Monsters: Pour the plain batter into free-form blob shapes. While cooking the second side, press candy eyes, banana slices, or chocolate chips into the pancake to create a face.

Serve: Serve immediately with maple syrup and extra toppings.
