Step‑by‑Step Instructions for Ruler Rice Krispies Treats

Step 1: Melt the Base
In a large pot, combine 4 tablespoons of butter and 10 ounces of large marshmallows. Heat over low heat, stirring frequently for about 5-7 minutes until the mixture is completely melted and smooth. Be sure to watch closely to prevent burning. As the butter and marshmallows blend, the nostalgic aroma will fill your kitchen, setting the stage for delightful Ruler Rice Krispies Treats.

Step 2: Color It
Once the mixture is smooth and creamy, remove the pot from heat. Immediately add about 1-2 tablespoons of yellow gel food coloring, stirring until the color is fully incorporated. This step is crucial for achieving that vibrant ruler hue—work quickly to ensure an even distribution of color throughout the marshmallow mixture, which should be a beautiful, sunny yellow.

Step 3: Mix Cereal
Now, it's time to fold in 6 cups of Rice Krispies cereal. Using a spatula, gently mix the cereal into the colored marshmallow base for about 2-3 minutes. Aim for an even coating of the crispy cereal, ensuring every piece is enveloped in that sweet, gooey mixture. The combination should be sticky and fluffy, indicating it's ready for the next step in creating your Ruler Rice Krispies Treats.

Step 4: Press Mixture
Prepare a 9x13-inch pan by greasing it with butter or lining it with parchment paper for easy removal. Transfer the Rice Krispies mixture into the pan and evenly spread it out. Using a potato masher or your hands, compact the mixture firmly into the pan until it’s smooth on top. This step is essential for achieving the perfect shape and texture for your ruler treats.

Step 5: Cool & Cut
Allow the mixture to cool at room temperature for about 30 minutes or until it’s completely set. Once cooled, use a sharp knife to cut the slab into ruler-shaped pieces, about 2 inches wide and 6 inches long. Ensure the knife is clean; running it under hot water can help make smoother cuts, allowing your Ruler Rice Krispies Treats to maintain neat edges for a polished presentation.

Step 6: Decorate
While your treats cool, melt a small amount of black melting candy in a microwave-safe bowl, heating in 30-second intervals until smooth. Transfer the melted candy into a piping bag or a plastic sandwich bag with a corner snipped off. Carefully pipe measurement lines onto each Rice Krispies treat, mimicking the look of a real ruler. Be sure to work quickly to prevent the candy from hardening before you finish your designs.

How to Store and Freeze Ruler Rice Krispies Treats

Room Temperature: Keep your Ruler Rice Krispies Treats in an airtight container at room temperature for up to 1 week for optimal freshness.

Fridge: If you prefer a firmer texture, store them in the fridge for up to 2 weeks, layering them between parchment paper to prevent sticking.

Freezer: For longer storage, wrap individual treats in plastic wrap and place them in a freezer-safe bag. They can be frozen for up to 1 month.

Reheating: To enjoy, simply let the frozen treats thaw at room temperature for about 30 minutes before serving, ensuring they retain their chewy goodness.

Make Ahead Options

You can easily prepare the Ruler Rice Krispies Treats in advance, making them perfect for busy schedules! Create the base mixture (butter, marshmallows, and Rice Krispies) up to 24 hours ahead of time. Simply follow the melting and mixing steps, then press it into the pan and allow it to cool completely before covering it tightly with plastic wrap to maintain freshness. For best results, wait to add the yellow coloring and decoration until just before serving to keep the colors vibrant and the appearance sharp. This way, when you’re ready to impress family and friends, you can simply cut and decorate, delivering those sweet, nostalgic treats with minimal effort!

Ruler Rice Krispies Treats Recipe FAQs

How do I select the best marshmallows for this recipe?
Absolutely! When choosing marshmallows, go for large, soft marshmallows rather than mini ones as they melt more evenly and create a smoother blended mixture. Check for any signs of the marshmallows being old, like a dry texture or stickiness, as fresh marshmallows will provide the best texture for your treats.

What is the best way to store Ruler Rice Krispies Treats?
You can keep these delightful Ruler Rice Krispies Treats in an airtight container at room temperature for up to 1 week. If you prefer a firmer texture, they can also be stored in the fridge for up to 2 weeks. Just be sure to layer them between parchment paper to prevent sticking; no one wants their treats to be a gooey mess!

Can I freeze Ruler Rice Krispies Treats?
Yes, you can absolutely freeze them! Wrap each treat individually in plastic wrap and place them inside a freezer-safe bag. They will retain their deliciousness for up to 1 month. When you're ready to enjoy them, simply unwrap and let them thaw at room temperature for about 30 minutes. They’ll be just as tasty as when they were first made!

What do I do if my Ruler Rice Krispies Treats are too hard or too soft?
If your treats end up too hard, it may be that you compressed them too much during the pressing step. For next time, try gently pressing them down rather than packing them tightly. In contrast, if they're too soft, ensure that you let them cool completely before cutting or decorating—this helps them firm up. You can also refrigerate them for a little while to help with firmness without sacrificing that gooey goodness.

Are Ruler Rice Krispies Treats safe for people with allergies?
If anyone in your home has allergies, it’s essential to check ingredient labels carefully. The standard ingredients may contain gluten or dairy. To make them allergy-friendly, use gluten-free crispy rice cereal and dairy-free butter alternatives. Always verify all ingredients, particularly any add-ins like candy, which might contain allergens.

Can pets have Ruler Rice Krispies Treats?
It's best to keep these treats away from pets. While plain Rice Krispies are generally safe in small amounts, the butter and especially the chocolate or melting candy can be harmful to dogs. Be sure to store your treats out of reach of furry friends to keep both them and your delicious Ruler Rice Krispies safe!
