Toxic Slime-filled Cupcakes!
Fudge cupcakes filled with toxic green slime!  Yummy white chocolate pudding makes the slime and fun buttercream and bones complete this mad-scientist dessert.  Print some free radioactive cupcake toppers and you have such a fun October treat!!

These cupcakes are delicious…..  I know the green slime might throw you off, but that slime is the creamiest pudding filling….oh my.  It is like a custard filled doughnut…but better.

I’m a scientist in my day job, so when thinking creepy I tend toward the blood and guts variety more than ghosts and monsters.  I knew I wanted green slime, so I looked up recipes for ideas (realistic slime….it needed to be realistic….)  and I came across an adorable blog with the idea of using plain old pudding with green food coloring– easy! Plus I loved her frosting “blob” technique, so a few parts of this recipe are borrowed from ideas on Make Bake Celebrate.

I also created some free printable “radioactive” cupcake toppers for you.  Just click here for the link, print 2 pages on card stock, cut them out and use double-sided tape to stick them back-to-back over a toothpick.    Easy-peasy and a perfect finish on these!  Aren’t they fun?!???

Lets make these cute little cupcakes together!  (printable recipe)

INGREDIENTS:

  • One boxed cake mix (plus water, oil and eggs to make according to box)
  • One box (3.3 oz.) Jello Brand White Chocolate Pudding (instant)
  • Milk (to make pudding according to package)
  • Green food coloring gel
  • Purple food coloring gel
  • 2 sticks (1 cup) salted butter
  • 2 sticks (1 cup) unsalted butter
  • 1 teaspoon clear vanilla
  • 3 cups powdered sugar
  • Sprinkles/ decorations for tops of cupcakes  (I used Wilton Bones Sprinkles)

DIRECTIONS:

  • Preheat oven to 350F degrees.
  • Make cupcakes according to box and divide evenly into 24 cupcake liners placed in cupcake tins.
  • Bake according to times given on boxed mix.
  • Remove from oven and cool completely.
  • Make pudding according to package and at the end add green food color gel (I used Leaf green by WIlton ) until it looks like radioactive slime!!!  Carefully spoon into a zip-top bag.
  • Core your cooled cupcakes- you can use a paring knife to just remove a core, but a cupcake corer is much faster and more uniform.  I use the Chicago Metallic Cupcake Plunger and it is cheap and small and perfect for the job!
  • Carefully clip a corner of your green slime (pudding) bag and fill each cupcake cavity about half full of “slime”.
  • Trim a little off the bottom of the “core” you removed and place it back on top of the filling- like a little cupcake cork!

  • Make frosting by combining butters, powdered sugar and vanilla in a large mixing bowl and beating it on high until light and fluffy.
  • Divide frosting in half and mix green into one half and purple into the other half until fully combined.
  • Place each color of frosting in a bag that has been fitted with a Wilton 2A round decorating tip.  Pipe round dots of frosting in alternating colors all over each cupcake top.

  • Add sprinkles, bones, skulls, eyeballs…. any cool and creepy decorations you want!
  • Top each cupcake with a free printable topper and ENJOY!!!!

My thoughts:  I would make these again in a heartbeat.  I might make them again this weekend.  Yes, they are super fun, but the pudding is really SO good inside!  I feel like every cupcake should have pudding inside…!  I always love to watch the reactions when people bite into things for the first time– and these don’t disappoint!!!  Lots of laughter and smiles at this yummy green slime!  Enjoy!!!!!! ~r

  10. I love this idea. Im making a ninja turtle cake in a couple days and needed an edible slime for the cake. I also have cupcake to make on the side and I am now going to do the slime in the middle of the cupcakes as well. So excited to see the kids reaction when they bit into them. Thanks for the idea!!

  11. Do you have to refrigerate them since they have the pudding in the middle?? Thank you for your help and recipe. I am making them today.

    • I’m so sorry I didn’t get back with you sooner! If you are keeping them for several days I definitely would refrigerate. The buttercream will harden up in the fridge though, so pull them out and let them warm up a little before serving.

  14. Would these need to be refrigerated because of the pudding?
    Can they be made ahead of time?

    • Hi Keri, Yes- refrigerate them, and No- you need to make them close to serving because the pudding will make your cookie cups soggy eventually. You could make the cups and fill them just before? Hope this helps!
