Is there anything cuter than Halloween rice krispie treats? They’re the perfect blend of cute and just a touch spooky, and easy enough to make with kids (and they’ll look like the pictures!).
This post is set up a little bit differently from normal. You can jump to each type of treat decoration style in the list below, or scroll through to see what’s used for each and step-by-step images.

Mummy Treats
Add the eyes first, attaching with a dab of buttercream. Pipe criss-crossing strips of frosting. Don’t cover the eyes, but frosting touching the eyes is okay! Repeat with the strips until covered.
Many Eyed Monster Treats
Spoon an uneven, dripped layer of glaze on two-thirds of the treat. Top with several candy eyes.
Frankenstein Treats
Top with a layer of glaze and add two eyes. Using black icing, pipe attached upside-down triangles at the top of the treat for hair. Pipe a squiggly line for the mouth and an intersected line as stitches. Add silver sprinkles for staples, and mini peanut butter cups as neck bolts (attach with more glaze).
Jack-O’-Lantern Treats
Fully cover the top of the treat in orange glaze. Pipe a jack-o-lantern shape with the black frosting and optionally add spooky eyes.
Tips and Notes
You’ll need a double batch of the rice krispie treats to make enough to frost with the different variations. Make them in a rectangular dish so that you can cut the longer rectangles rather than squares.
We use this American buttercream for piping on the mummy treats. The glaze topping the others is a simple icing sugar and milk glaze, with food colouring added as needed.
Add a little orange or green food colouring to the marshmallow base of the treats while cooking if you’d like.
Beyond what we’ve outlined here, there are lots of other Halloween rice krispie treat options! Think ghosts, spiders, and vampires (pipe fangs or use large white sprinkles). Or go more cute with pumpkin cookie cutters and glaze like we did for our cinnamon sugar cookies.
Substitutions
Use melted chocolate in place of the black piping gel, or tint some buttercream black to use instead. We like using the gel pictured as it’s so kid-friendly and easy.
If you don’t want to use glaze, try candy melts instead. They’re already coloured and easy to melt in the microwave.
Try flavouring the base of the treats with pumpkin pie spice for a seasonal twist.
To make vegan Halloween rice krispie squares, use vegan marshmallows (we like Dandies), vegan butter, and our vegan vanilla buttercream for frosting.
