Step‑by‑Step Instructions for Ruler Rice Krispies

Step 1: Prepare the Baking Dish
Start by preheating your kitchen to a cozy atmosphere, then take a 9×13 inch baking dish and line it with parchment paper, ensuring the paper hangs over the edges for easy removal. Spray the parchment generously with non-stick cooking spray to prevent any sticky surprises later. This will be your canvas for the delightful Ruler Rice Krispies.

Step 2: Melt Butter and Marshmallows
In a large saucepan, place 3 tablespoons of butter over low heat. As the butter begins to melt, gently stir in a full bag of mini marshmallows. Keep stirring continuously for about 5-7 minutes until the mixture becomes smooth, creamy and slightly bubbly. This gooey concoction will be the heart of your Ruler Rice Krispies!

Step 3: Combine with Rice Krispies
Once the marshmallows have melted perfectly, remove the saucepan from heat. Pour in 6 cups of Rice Krispies cereal, stirring gently but thoroughly until each piece is completely coated in the marshmallow mixture. This step should take about 2-3 minutes, and you'll know it's ready when you see no dry cereal peeking through the sticky goodness.

Step 4: Divide the Mixture
Transfer the mixture to a clean surface and quickly divide it into three equal portions. Leave one portion plain and add yellow gel coloring to another and red gel coloring to the last. Use your hands or a spatula to mix until the colors are vibrant. These colors will bring your Ruler Rice Krispies to life!

Step 5: Layer the Mixtures
Now it's time to create the colorful layers! Start by pressing the red mixture evenly into the bottom third of your prepared baking dish, using the spatula for smoothness. Follow with the yellow mixture for the center layer and finally, press the plain mixture on top. Make sure each layer is packed tightly and smooth—this will help your treats maintain their shape.

Step 6: Allow to Cool
Once all the layers are in place, allow the Ruler Rice Krispies to cool completely at room temperature. This should take about 30 minutes. You'll know they’re ready when they feel firm to the touch. Patience here ensures beautifully cut bars later on.

Step 7: Cut into Bars
Once cooled and set, lift the entire block out of the dish using the parchment paper overhang. Place it on a cutting board and, using a sharp knife, slice the treats into long rectangle bars, resembling rulers. Aim for about 12 bars for perfect portion sizes to share!

Step 8: Melt and Decorate
In two separate microwave-safe bowls, melt ½ cup of white candy melts and ½ cup of chocolate chips. Heat them in the microwave in 20-second intervals, stirring frequently until smooth. Use a piping bag or a spoon to create ruler markings with the melted chocolate and a “metal edge” using the white melts on one side of the treat.

Step 9: Add Finishing Touches
After adding the basic designs, take a black edible marker or decorating gel to draw numbers and small lines on the treats, enhancing the ruler effect. Let your creativity run wild here; this is the fun part that brings your Ruler Rice Krispies to life!

Step 10: Set and Serve
Allow all decorations to set for about 15 minutes, then your creative Ruler Rice Krispies will be ready to serve! Whether for a party, a snack, or a fun treat at home, these eye-catching bars are sure to delight. Enjoy the smiles they bring!

Make Ahead Options

These Ruler Rice Krispies are ideal for busy home cooks looking to streamline their meal prep! You can prepare the colorful Rice Krispies mixture up to 24 hours in advance.

This way, you'll delight your family and friends with freshly decorated treats, just as delicious as if made on the spot!

Expert Tips for Ruler Rice Krispies

Uniform Color Mixing: Ensure each colored portion of the mixture is well-mixed for vibrant and consistent colors in your Ruler Rice Krispies.

Don’t Rush Cooling: Allow the layered treats to cool completely; this makes cutting much easier and prevents messy bars.

Sharp Knife for Cutting: Use a sharp knife to slice into bars for clean edges; a dull knife may crush the layers.

Experiment with Flavors: Try adding flavored extracts, like vanilla or almond, to the melted marshmallow for extra deliciousness without losing the classic taste.

Wrapping for Freshness: Store your Ruler Rice Krispies in an airtight container at room temperature to keep them chewy and fresh for up to five days.

Avoid Overheating: When melting candy melts or chocolate chips, heat in short intervals to prevent scorching; stir often for a smoother texture.

How to Store and Freeze Ruler Rice Krispies

Room Temperature: Store Ruler Rice Krispies in an airtight container at room temperature for up to 5 days to maintain their delightful chewy texture.

Fridge: If you prefer a firmer treat, refrigerate them for up to a week, but ensure they’re tightly wrapped to prevent them from drying out.

Freezer: For longer storage, freeze Ruler Rice Krispies in individual pieces wrapped in plastic wrap, then place in a freezer bag for up to 3 months.

Reheating: When ready to enjoy, thaw at room temperature for about an hour, or microwave briefly (10-15 seconds) for a soft, gooey treat again!

Ruler Rice Krispies Recipe FAQs

What is the best way to choose ripe ingredients for my Ruler Rice Krispies?
Absolutely! While the ingredients for this recipe are mostly shelf-stable, it’s important to ensure your mini marshmallows are soft and fresh. Check the expiration date and choose a bag that feels light and fluffy without any hard clumps. For the gel food coloring, ensure the tubes are well-sealed and not expired for the best color effect!

How should I store my Ruler Rice Krispies?
Store your Ruler Rice Krispies in an airtight container at room temperature for up to 5 days. This helps maintain their chewy, delicious texture. If humidity affects your area, consider wrapping the bars individually in plastic wrap for added protection against moisture.

Can I freeze my Ruler Rice Krispies?
Absolutely! For longer-lasting treats, freeze your Ruler Rice Krispies by wrapping each bar tightly in plastic wrap, then placing them in a freezer-safe bag. They can be stored for up to 3 months. When you're ready to indulge, simply thaw at room temperature for about an hour. For a quick fix, microwave them for 10-15 seconds to restore their gooeyness.

What should I do if my Ruler Rice Krispies are too sticky or fall apart?
Very! If your Ruler Rice Krispies are too sticky, it may be a sign you added too much marshmallow or didn't let them cool properly. To troubleshoot, try refrigerating them for 30 minutes before cutting, which may firm up the layers. If they fall apart, ensure you’re pressing the mixture firmly into the pan to create cohesive layers!

Are Ruler Rice Krispies safe for people with allergies or dietary restrictions?
Definitely! While this recipe is generally safe, it contains marshmallows and butter, which may not be suitable for individuals with dairy or gluten sensitivities. Always read ingredient labels, and if you have concerns, consider making your own marshmallows or using dairy-free alternatives to butter to suit various dietary needs.

How long should I let the Ruler Rice Krispies cool before cutting?
After combining the mixtures in the baking dish, let the treats cool at room temperature for about 30 minutes. They should feel firm to the touch before cutting. Take your time – rushing this step can lead to messy bars that don't hold their shape.
