Tip

Depending on the brand, the red gel might be labeled as "decorating gel." Make sure the tube has a pointed nozzle.

Remove the pot from the heat. Add the vanilla extract and about 10 drops of red food coloring, one by one, while mixing constantly. (You might need more than 10 drops, depending on your specific food coloring and desired hue.) Aim for a color between beige and pink.

Tip

Once you remove the marshmallows from the heat, try to work briskly. The melted marshmallows will get sticky quickly.

5. Add the cereal

6. Shape your Halloween desserts

Lightly grease a large spoon and your hands; this will prevent the treats from sticking. Check the Rice Krispie mixture to make sure it's cool enough to touch but still moldable.

Use the spoon to scoop up about 1/3 cup (it's OK if it's not exact). Form the mixture into an oval shape, with one end slightly more narrow than the other, about 3 inches long.

Tip

If the mixture in the pot hardens before you're done, you can re-melt it over low heat.

7. Make your brains

Using a butter knife, make an indent in the center of each oval to create the brain shape. Let the treats harden completely.

To each Rice Krispie treat, add a line of red gel icing along the indent. Add zig-zag lines branching out from the center.

Tip

Store your leftovers in an air-tight container to pull out as a Halloween treat at your next party.

Happy Halloween!
