Calories: ~140 per treat
Ingredients:
- 6 cups Rice Krispies cereal
- 3 tablespoons butter
- 1 (10 oz) bag mini marshmallows
- Yellow food coloring (optional, for ruler color)
- Black edible food marker or melted chocolate for markings
- White candy melts (optional, for numbers or edge details)
👩🍳 Instructions
Melt the butter in a large saucepan over low heat. Add marshmallows and stir until completely melted and smooth. If using, stir in a few drops of yellow food coloring until you get the desired shade.

Transfer the mixture to a greased 9×13-inch pan. Press evenly using a spatula or wax paper. Let cool for about 10 minutes.
Once set, cut into rectangular bars (about 1 inch by 4–5 inches) to resemble rulers.
Use the edible marker or melted chocolate to draw ruler lines and numbers on each treat. Get creative! You can also use a piping bag and candy melts for more detailed decorating.
Let decorations set before serving or packaging.
