LEGO Party Treats transform 12 store-bought crispy rice bars with bright candy-melt coatings and matching candy studs. Leaving some bars full-size and cutting others creates a playful assortment of rectangular, square, and tiny brick shapes without baking or making marshmallow cereal mixture from scratch.
Plan about 60 minutes for unwrapping, cutting, melting five colors, decorating, and setting. Work with one candy color at a time so its coating remains fluid, and attach the matching M&M's before that surface hardens.
Colorful LEGO Treat Ingredients
Begin with exactly 12 individually wrapped store-bought Rice Krispies Treats. For the colored tops, use candy-melt wafers in red, yellow, orange, green, and blue. The recipe does not assign a fixed total weight because the amount depends on how many treats receive each color.
Select M&M's in those same five colors to form the studs. Keep a little vegetable oil available only if a melted coating is too thick to spread. No additional cereal, marshmallow, butter, or frosting is required.

How to Make LEGO Rice Krispies Treats
- Unwrap all 12 treats and arrange them on a parchment-lined baking pan. Leave bars whole for large bricks.
- For square bricks, cut roughly one-third from selected bars. Use each small offcut to make the tiniest bricks.
- Place about ½ cup of one color candy wafers in a microwave-safe bowl. Microwave in 30-second bursts, stirring after each, until smooth.
- If the coating is too thick, stir in only a tiny amount of vegetable oil.
- Spoon the melted color over the top of each chosen treat and spread it evenly.
- While wet, press matching M&M's on top in arrangements of 2, 4, or 6 studs. Repeat one color at a time.
- Set at room temperature until hard, or refrigerate about 15 minutes.

Create Several Brick Sizes
Full bars naturally resemble long bricks and need no trimming. To create a square, slice about one-third from a bar with a sharp knife. Save that offcut rather than discarding it, because its compact shape becomes a tiny brick after coating.
Make clean, straight cuts without compressing the cereal. A lightly sawing motion works better than forceful downward pressure. Arrange all shapes on parchment with space between them before melting candy, since the coating stage moves quickly.

Organize Five Matching Color Stations
Separate red, yellow, orange, green, and blue wafers before beginning, and sort the matching candies into their own small groups. This preparation prevents searching for the correct studs while a freshly coated surface begins to harden.
Use one microwave-safe bowl per color when possible, or wash and dry the bowl completely between colors. Even a small trace can muddy a bright shade. Keep utensils separate too, especially when moving from a dark color into yellow.
Melt Candy Wafers Gradually
Begin with roughly ½ cup wafers of the first color. Microwave for 30 seconds, stir thoroughly, then continue in 30-second bursts. Stirring between every interval distributes residual heat and prevents scorching around the bowl's edges.
Stop heating as soon as the final pieces dissolve through stirring. If the coating is smooth but too thick to spread, mix in a tiny amount of vegetable oil. Add it sparingly; excessive oil can make the coating slow to set or appear greasy.
Coat Only the Top Surface
Spoon a modest amount of melted candy over the top of one crispy rice shape. Spread it from edge to edge with the back of the spoon or a small knife. The recipe calls for covering the top, not dipping the entire bar, which keeps the treat easy to handle and avoids an overly thick coating.
Work over parchment so drips release after setting. Finish a manageable number in the current color rather than coating all 12 at once. The studs must be attached while every top remains glossy and wet.
Arrange Two, Four, or Six Studs
Choose the stud count according to the brick shape. Two matching M&M's suit a tiny piece, four fit a square, and six create two tidy rows on a longer rectangle. Press each candy gently into the wet coating without pushing down to the cereal layer.
Keep every stud the same color as its coating: red on red, yellow on yellow, orange on orange, green on green, and blue on blue. Even spacing creates a recognizable brick pattern and helps the simple store-bought base look carefully finished.
Let the Decorations Set Completely
Leave the decorated bars undisturbed at room temperature until the coating is hard and no longer glossy. For faster results, place the pan in the refrigerator for about 15 minutes, as the original recipe allows.
Do not stack or transfer treats while the coating is soft. The stud candies can slide and bright colors can smear onto neighboring pieces. Once set, lift each treat by its cereal sides rather than touching the decorated top.
Plan the Work Color by Color
A reliable sequence is melt, coat, add studs, and set one color before starting the next. This is more controlled than melting all five bowls at once, because candy wafers begin thickening as they cool. If a bowl firms during use, warm it for a short interval and stir.
Distribute shapes among colors before melting so the final platter has a balanced assortment. There is no required count per shade. Preserve the total starting quantity of 12 bars, recognizing that cutting selected bars creates additional individual pieces.
Storage and Party Presentation
After the coating is firm, store the treats airtight at cool room temperature with parchment between layers. Moisture and heat can soften the cereal or dull the candy finish. If the room is warm, refrigerate briefly and bring the treats out near serving time.
Arrange the five colors in loose rows or a mixed pattern on a clean platter. Avoid stacking too high because the studs create an uneven surface. These are especially useful for a themed birthday table because the decoration is completed before guests arrive.
Troubleshooting the Candy Coating
Thick coating usually needs more stirring before oil. Candy melts often become smoother as the bowl's retained heat finishes melting them. Add only a tiny drop of vegetable oil if stirring does not solve the problem.
Studs that fall off were probably placed after the surface began setting. Rewarm a little matching coating, use it as edible adhesive, and let the treat harden again. Crumbled bars were likely cut with excessive pressure, so use a sharper knife and gentle sawing motion next time.
Conclusion
Unwrap 12 crispy rice treats and cut selected bars into square and tiny shapes. Melt about ½ cup candy wafers one color at a time in 30-second intervals, thinning with a tiny amount of oil only if needed. Coat the tops, add matching M&M's in 2-, 4-, or 6-stud patterns, and set at room temperature or chill 15 minutes.
Frequently Asked Questions
- → How many crispy rice treats do I need?
Start with exactly 12 store-bought treats; cutting some creates a larger number of differently sized finished pieces.
- → How much candy melt should I heat at once?
Begin with about ½ cup of one color and melt more only when needed.
- → Why should I decorate one color at a time?
The matching candy studs must be attached while the coating is wet, so one-color batches prevent it hardening too soon.
- → How quickly can I set the treats?
Let them harden at room temperature, or refrigerate the pan for about 15 minutes to speed setting.
