Step‑by‑Step Instructions for Ruler Rice Krispies
Step 1: Prepare the Baking Dish
Start by preheating your kitchen to a cozy warmth. Take a 9×13 inch baking dish and line it with parchment paper, ensuring the paper hangs over the edges for easy removal later. Spray the parchment thoroughly with non-stick cooking spray to prevent any sticking.
Step 2: Melt the Butter and Marshmallows
In a large saucepan, melt 3 tablespoons of butter over low heat. Once the butter is completely melted, add a 10 oz bag of mini marshmallows. Stir constantly with a spatula until the marshmallows are fully melted and smooth, which should take about 5 minutes. Remove the pan from the heat once you achieve a glossy mixture.
Step 3: Combine with Rice Krispies
Quickly pour in 6 cups of Rice Krispies cereal into the melted marshmallow mixture. Gently fold the cereal using a spatula until every Rice Krispie is well-coated with the gooey marshmallow mixture. This should take about 2-3 minutes.
Step 4: Divide the Mixture
Carefully divide the mixture into three equal portions. Transfer one portion to a separate bowl to remain plain, adding red gel food coloring to the second portion and yellow coloring to the last. Stir each mixture until the colors are vibrant and evenly distributed, making sure each color stands out beautifully.
Step 5: Layer the Colors
Using your clean spatula, begin by pressing the red mixture firmly into the bottom third of the prepared baking dish. Next, sprinkle the yellow mixture into the center third, pressing down evenly. Finally, add the uncolored mixture on top, smoothing it out to create a flat surface. Allow the layers to cool completely for about 30 minutes.
Step 6: Cut into Bars
Once the layered treats are set and firm, slice them into long rectangle bars to resemble rulers. Aim for uniformity, making sure each piece is about 1 inch wide for a neat appearance. This step allows you to create the fun shape of your Ruler Rice Krispies.
Step 7: Melt the Candy Coatings
In two separate microwave-safe bowls, melt ½ cup of white candy melts and ½ cup of chocolate chips in 30-second intervals, stirring after each session to prevent overheating. Aim for a smooth consistency; this will be used for decorating.
Step 8: Decorate the Bars
Using a piping bag or a spoon, carefully add ruler markings with the melted chocolate onto one side of each treat. Create a “metal edge” by drizzling melted white candy melts along the other side. This will enhance the ruler appearance significantly.
Step 9: Final Touches
Utilize black decorating gel or a black edible marker to add numbers and small lines on your Ruler Rice Krispies. Take your time to ensure the markings are neat and resemble an actual ruler, which adds a fun touch to your delightful treats.
Step 10: Let Set and Serve
Allow the decorated Ruler Rice Krispies to set fully before serving or wrapping them for later enjoyment. This ensures that the coatings have hardened, making your colorful creations not only beautiful but also easy to handle and deliciously satisfying!
Make Ahead Options
These Ruler Rice Krispies are perfect for meal prep enthusiasts! You can prepare the treat layers up to 24 hours in advance by following the usual steps, but before pressing them into the baking dish, allow them to cool completely. Once the layers are done, wrap the entire dish tightly in plastic wrap and refrigerate. This helps maintain their delightful texture and vibrant colors until you're ready to finish them. When it’s time to decorate, simply melt the candy coatings and add the markings as instructed, and your Ruler Rice Krispies will be just as delicious and visually appealing as if they were freshly made!
Tips for the Best Ruler Rice Krispies
Perfect Color Mixing: Ensure you use gel food coloring rather than liquid to achieve vibrant, consistent colors without altering the texture of your Ruler Rice Krispies.
Cooling Time: Be patient! Allowing the mixture to cool completely ensures the layers stay firm and hold their shape when cut, preventing any mess.
Avoid Over-melting: Melt the butter and marshmallows on low heat only, avoiding burning which could ruin the gooey texture essential for great Ruler Rice Krispies.
Cut with Care: Use a sharp knife to cut the treats into even bars. This not only makes for a professional presentation but also ensures a delightful experience for everyone.
Decorate with Precision: When adding ruler markings, take your time for neatness. You want those little details to shine, bringing your Ruler Rice Krispies to life!
