How to Make Ruler Rice Krispie Treats
Let’s walk through this step-by-step. You’ll have a tray of rulers ready in under 30 minutes!
- Unwrap the Rice Krispie Treats.
Take each one out of its packaging. - Shape each treat.
Flatten them slightly and use a bench scraper or knife to make the edges more rectangular and ruler-like. Sharper edges help the tick marks look neater. - Melt the candy melts.
Place the black candy melts in a microwave-safe bowl. Heat in 20-second intervals, stirring in between, until smooth. - Prepare your piping bag.
Spoon the melted chocolate into a piping bag or a zip-top bag. Snip a small hole at the tip. - Decorate!
Pipe short and long tick marks along one long side of each treat, mimicking a real ruler. 🎓 - Let them set.
Lay the treats flat and allow the chocolate to harden. This takes about 10 minutes at room temperature.
Now they’re ready to serve!

Can You Store or Make Them Ahead?
Absolutely! 🙌
Store the finished ruler treats in an airtight container at room temperature. They’ll stay fresh for up to 1 week.
If you’re making them for a big event or classroom party, you can prep them 1-2 days ahead with no problem.
Just make sure to let the chocolate fully harden before stacking them.

Common Questions About Ruler Rice Krispie Treats
Can I use homemade Rice Krispie treats instead?
Yes! Just make sure they’re cooled and firm before shaping them. Homemade versions may be softer, so chill them first for better results.
What if I don’t have a piping bag?
A zip-top bag works great. Just snip a tiny hole in one corner for piping.
Are these safe for nut-free classrooms?
Check your Rice Krispie treat packaging and candy melts. Many are nut-free, but always read labels to be sure.

Can I freeze them?
It’s not recommended. Freezing can change the texture of the treats and cause condensation when thawing, which affects the chocolate.
Do I need a ruler to guide my tick marks?
Not really! You can eyeball the marks. But if you want precision, lay a real ruler beside the treat for guidance.
Can I use melted chocolate chips instead of candy melts?
Yes, but candy melts harden better and are easier to pipe. If using chocolate chips, add a little coconut oil for smoothness.
