How to make LEGO Rice Krispie Treats
LEGO Rice Krispie Treats are perfect for any kids birthday party. I mean, what kid doesn’t love LEGOS? The only thing that can make them better is if you can eat them.
Seriously though, your kids are going to love these LEGO Rice Krispie Treats. They’re cute, colorful and super fun to make.
To get the multiple colors you will need to know how to make Rice Krispie Treats with food coloring. We’ll list the basics below but you will also need to reference our other colored Rice Krispie Treats, like Blue Rice Krispie Treats, Yellow Rice Krispie Treats, Green Rice Krispie Treats, or Red Rice Krispie Treats for more details.
If you’ve worked with food coloring before, you’ll have no problem. It’s actually very similar to the Sesame Street Rice Krispie Treats, minus the googly eyes, of course.
Melt your butter in a large stock pot. We usually do this on our stovetop with medium heat.
When your butter is mostly melted, you can add your marshmallows. If you are making a full batch for each color, you’ll use a full 16 ounce bag. If you are making the colors out of one single batch, you’ll want to split that bag into quarters or 4 ounces each color.
Stir the marshmallows and butter together with a spatula until everything is completely melted. You should have an almost complete liquid with a golden buttery sheen to it. You can follow the Microwave Rice Krispie Treats recipe to speed this part up, if you like.
You want to decide which color brick you would like to make first. For instance, we’ll start with red. Take your red food coloring and add it liberally to the melted marshmallows.
You’ll want to stir while you’re adding food coloring so that you can make sure you’re using enough. You want your LEGO bricks to be bright and colorful, so we always use a lot of food coloring.
Once you have the correct color, reduce your heat to low or medium low. You do this so that marshmallows do not overcook and become brittle.
Now it’s time to add in your Rice Krispies. If you’re making a full batch of red, you’ll use six measured cups. If you are making quarters then you’ll want to use somewhere around 1 1/4 to 1 1/2 cups.
Once you’ve added in your cereal, continue to stir with your spatula until everything is an even color and evenly coated in marshmallows. You may need to add more food coloring at this point. Just check on the color and see how satisfied you are.
Now that everything is mixed and a bright red color, you’ll want to get out either an 8 x 8 baking pan, if you’re making batches in quarters, or a 9 x 13 baking pan, if you’re making each color its own batch. You also want to get a can of spray Canola oil.
Spray the inside of whichever pan you decide to use with canola oil. You want to coat the bottom and the inside walls completely.
Now scoop your Rice Krispie Treat mix into the bottom of that pan. Using your spatula, flatten it out until it is completely even.
Now set this color to the side and allow it to cool and move on to the next color. You’ll repeat steps 1 through 3, three more times until you have all four colors.
Now that you have all four colors completed, it’s time to cut them and prepare them for decorating. You’ll still cut them the same way regardless of if you made an 8 x 8 pan or a 9 x 13 full batch for each color.
You’ll want to cut them into rectangles instead of the normal squares. Now we typically cut them 2 inches long and 1 inch wide. If you want larger blocks, you can just as easily cut them 4 inches long and 2 inches wide.
The decorating part is the easiest of all. All you need for decoration is either a bag of M&M minis or full size plain M&M’s.
If you cut your LEGO blocks into two by one inch rectangles, you will use the M&M minis. Simply arrange them across the top of the LEGO block in a 2 x 3 grid. You may need to push the M&M slightly down into the Rice Krispie Treat, just to make sure that they don’t fall off.
If you’ve made the larger 4 x 2 inch LEGO blocks, you’ll want to use the full sized plain M&M’s. Arrange them in the same 2 x 3 grid as you did in the previous instructions.
All that’s left is to stack them creatively and unveil them to your awaiting guest.
