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)
- 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)
- 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
