Turn store-bought Rice Krispy treats into fun, ruler-shaped snacks with just black candy melts! A quick, no-bake back-to-school treat ready in 10 minutes.
Unwrap each Rice Krispy treat and gently press it into a more rectangular shape. Use a bench scraper or the edge of a spatula to help keep the sides straight and neat.
Melt the black candy melts, then pour them into a piping bag.
Snip a small hole at the tip of the bag and pipe ruler-style tick marks along one long edge of each treat. Vary the lengths of the lines to mimic a real ruler.
Let them sit for about 10 minutes, or until the candy melts are fully set.
