Halloween is a fun time to whip up some cool treats. Why not spoil guests at a holiday party or kids at their school class party with these easy to assemble goodies. Pumpkin Rice Krispie Treats. This ain’t your ordinary Rice Krispie Treat. Oreo Spiders. This no bake treat is one the kids can make all on their own. Pumpkin Lollipops. These suckers are such a clever idea. Not only are they darling treats, but they are so simple to assemble.
