Melt the butter in a large pot over low heat. Add the mini marshmallows and stir often until smooth and fully melted, about 4-5 minutes.
03 -
Remove the pot from the heat. Stir in the cherry gelatin powder, vanilla, and salt until the mixture is evenly pink with no dry streaks.

Add the crisp rice cereal and fold with a greased spatula until the cereal is evenly coated. Work gently so the cereal stays light.

Transfer the mixture to the prepared pan. Use greased hands or parchment to press it into an even layer without compacting it hard.

Melt the dark chocolate in 20 second microwave bursts, stirring after each burst. Stir in oil if needed, then drizzle over the treats. Add sprinkles while the chocolate is wet if using.
07 -
Let the treats stand at room temperature for 45-60 minutes, until the chocolate is firm. Lift out with the parchment and cut into 16 squares.
