Melt butter over medium heat. Add marshmallows and stir until melted. Add cereal and remove from heat stirring until completely coated. Pour onto greased baking sheet with the extra mini marshmallows if desired. Gently press out and let firm up for a few minutes. Using the star cookie cutter of choice press out the cereal. You may need to reshape when removing cutter. Let these cool. Heat up chocolate chips with oil in 10 second increments and stirring between. Put into a baggie and press to a corner. Snip a tiny piece off that corner and use it to drizzle on the chocolate. If using the sticks to make pops insert these just after removing the cookie cutter. A little extra mixture may need to be added to secure the back.
