Tip

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

Step 1

Line a large baking sheet with parchment paper or a silicone baking mat. Alternatively, you can grease the sheet. Set aside.

Step 4

Remove the pot from the heat. Add the vanilla extract and about 10 drops of 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 to pink.

Tip

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

Step 5

Add the Rice Krispy cereal and mix until fully coated.

Step 6

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

Use the spoon to scoop up about 1/3 cup (it's okay 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.

Step 7

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

Step 8

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