Prepare the Rice Krispie Treats by melting the butter over low heat. Once melted, stir in the marshmallows until the mixture is smooth. Remove from the heat and stir in the vanilla extract.
In a large bowl, pour the marshmallow mixture over the Rice Krispies and mix until completely combined.
Grease a baking sheet and flatten the Rice Krispie mix. Use a Mickey Mouse cookie cutter to shape the treats. Use your hands to add more of the cereal mixture to the mold, if needed. (Watch the video down below to see how to do this).
Transfer the Mickey-shaped treats to a sheet of parchment paper or wax paper and allow them to cool.
While the treats are cooling, begin melting the white candy melts. Follow the package directions for your microwaves wattage.
When the white candy is melted, dip the front of each Mickey treat in the candy to completely cover the front. Place the treat back on the wax paper.
After you have dipped the Rice Krispie Treats, cut each jumbo marshmallow in half.
Use a fork to dip the outside of the marshmallow half in the white candy melt, then roll it in coconut flakes.
Attach the marshmallow tail to the bunny treat (the white layer on the treat should still be wet).
Add the remaining melted white candy to a piping bag, and pipe a white circle around each of Mickey's ears to create the outline of the bunny's paw.
Melt the pink candy melts according to the package directions. Add the melted candy to a piping bag and pipe on the rest of the bunny paw.
Allow the candy melts to harden, then you can serve to your friends and family! Store them in an airtight container for up to two days.
