Ingredients and substitutions
- Rice krispies cereal - The cereal and chocolate chips can be substituted with cocoa krispies cereal if desired.
- Butter - Salted butter can be substituted with unsalted butter and a pinch of salt.
- Semi-sweet chocolate chips - Can be substituted with other baking chip flavors for a different color and flavor.
- Marshmallows - Regular or mini marshmallows can be used in this recipe. I prefer mini marshmallows because they melt quickly.
- White chocolate chips - I find that white chocolate chips are best for drawing spider webs. Melting wafers could work, but melt into a thinner consistency that's difficult to control.
How to make spider web Rice Krispies treats
- Melt butter, mini marshmallows, and chocolate chips over low heat. Stir until evenly incorporated and remove from heat.
- Stir in Rice Krispies until evenly coated and then press into a greased 9x13 pan. Cool for 10 minutes.
- Slice treats into 2 inch squares and place on a cooling rack to decorate.
- Melt white chocolate chips and pipe them in spider web patterns on your treats. Refrigerate for 10 minutes to set the chocolate before serving.
Tips and tricks
Piping bag - Carefully pour your melted chocolate into a plastic sandwich bag or small piping bag. Seal the bag, then cut off a small tip from one of the corners.
Drawing spider webs - Starting at one corner of the rice krispies treat, draw four lines of the same length out from the corner to create a starburst pattern. Then, draw a swooping line to connect the ends of each line together. Last, add one more set of swooping lines halfway down the four lines to complete the spider web design.
Chocolate consistency - If your chocolate is very warm, it may be too runny and difficult to control. If this is the case, allow it to cool and thicken for a few minutes before continuing.

Yes! Layer your rice krispies treats between sheets of wax paper in an airtight container. They should last about six weeks in the freezer when stored properly.
Marshmallows can be substituted with a jar of marshmallow fluff. The butter and marshmallows could also be substituted with ¾ cup of peanut butter and ¾ cup of honey heated over medium heat until melted and smooth, similar to the base of scotcheroos.

- 10 ounces (284 g) mini marshmallows
- 1 cup (170 g) semi-sweet chocolate chips
- 6 cups (168 g) rice krispies cereal
- ½ cup (85 g) white chocolate chips
Instructions
- In a saucepan over low heat, melt butter. Add mini marshmallows and chocolate chips, stirring until melted and evenly incorporated. Remove from heat.

- Slice rice krispies into 2 inch squares and transfer to a cooling rack or sheet of wax paper for decorating.
- Add white chocolate chips to a microwave safe bowl. Heat in 30 second increments until warm, then stir until melted. Carefully pour white chocolate into a plastic sandwich bag or piping bag, seal, and cut off the tip from one corner.
- Draw spider webs onto each treat. Start in one corner and draw four even lines outward to make a starburst pattern. Connect the lines with a swooping line at the ends, and again in the middle, to make a spiderweb pattern. Transfer treats to refrigerator for 10 minutes to allow chocolate to harden before serving.
