Let’s break down the process into easy-to-follow steps.

Step 1: Prepare Loaf Pan. Coat a 9×5-inch loaf pan with cooking spray and line with 2 strips of parchment paper (perpendicular and overlapping), leaving an overhang. Spray the parchment with cooking spray. This will make it easy to lift the finished cereal treat loaf out of the pan.

Step 2: Melt and Mix (First Layer). Put 1 ½ cups of the mini marshmallows and 1 tablespoon of the butter in a medium microwave-safe bowl. Microwave until the marshmallows are puffed and the butter is melted, about 1 minute. Stir until completely smooth (microwave for 30 more seconds, if necessary). Tint with food coloring, stirring to combine. Add 1 ½ cups of the cereal and stir until well coated.

Step 3: Press into Pan. Spray your hands or a rubber spatula with cooking spray. Press the mixture into the prepared loaf pan in an even layer.

Step 4: Repeat for Remaining Layers. Repeat steps 2 and 3 three more times, tinting each batch of marshmallow mixture a different color and pressing the cereal mixture into the pan in layers.

Step 5: Compact and Chill. Once all of the layers are complete, press the mixture down firmly in the loaf pan to make it compact. Refrigerate until very firm, about 20 minutes.

Step 6: Cut into Eggs. Lift the cereal treat loaf out of the pan using the overhanging parchment paper; remove the parchment. Cut the loaf crosswise into ¾- to 1-inch-thick slices. Using a 3- to 4-inch egg-shaped cutter, cut 1 egg diagonally from each slice.

These instructions are clear and not too difficult.
