How to Make Frankenstein Rice Krispies with Cupcakes in a Jar

Cupcakes: 25-30 min

Preheat the oven to 350 degrees.

Make cupcakes to package instructions.

Add 2 drops of green gel food coloring (I used neon green but any green works)

Separate evenly into cupcake tins

Bake for 15-18 mins, remove from oven and allow to cool

Frosting: 15min

Beat butter on medium speed in a stand mixer or with a handheld until fluffy

Gradually beat in the powdered sugar

Add the vanilla and milk and beat until incorporated, about 2 mins

Tint buttercream icing purple (I used 2 drops electric purple, Violet can also be used)

Beat for 5 mins on high to make it super silky

Add buttercream to a piping bag (or Ziplock bag) fitted with a 1M or 2D piping tip

Franken pops:25 mins

Melt the green candy melts and add in 1-2 tsp of coconut oil (you can also use vegetable oil)

Melt on 30 second increments at a time until melted, do not overheat it, as it will burn.

Mix it well, adding 1 tsp of oil at a time to make it smooth.

Once melted (should take no longer than 60-90 secs) dip the rice krispy treat face down into the


Add candy eyeballs immediately

Once all are completed set them to side and repeat the melting process with black candy melts

Add the melted black candy to a piping bag or Ziplock bag and snip a small hole in the tip

Making small up and down movements while squeezing the black candy, create the hair.

Once the hair is created, give the face eyebrows, a mouth and a little zigzag scar at the bottom

right corner.

Allow to set for 10 mins or until completely dry.

Add the popsicle sticks to the bottom then set aside.

Assembly: 5-10 mins

Remove the cupcakes from their liners and slice them in half crosswise.

Place one half in the jar upside down

Squeeze a circle of frosting around the top, applying even pressure the entire time.

Add the other half of the cupcake on top and repeat with frosting.

Slice another cupcake in half and add a third layer to the jar, top with frosting and sprinkle

Once all of the jars are filled, add the Frankenstein rice krispy pops to the center of the jars to

complete the project.


If working with kids add the popsicle sticks to the rice krispy treats before decorating, but make

sure your bowl is large enough to dip the rice krispy treat.

It is strongly recommended to use piping bags to have more control over the design, but ziplock

bags will work.

Sprinkles can be added at each layer if you would like.

Each jar should have 3 sections of cake and 3 sections of frosting
