- Halloween Sprinkles – If you want you can easily sprinkle on some Halloween sprinkles to dress up the cupcakes in a jar even more.
How to Make
Step 1: Start by preheating the oven and place liners in the cupcake pan. Then mix up the cake mix and add in the 1 teaspoon of vanilla to the cake mix. This dresses up the flavor.
Step 2: Pour the batter into the cupcake tin around 3/4 the way full. Bake for 15-18 minutes or until the cupcakes are done. Let cool completely.
Step 3: Work on making your Frankenstein Rice Krispies, directions are here.
Step 4: Once cupcakes are cooled work on the buttercream frosting. Beat butter on medium heat with a hand mixer, until fluffy.
Work in the powdered sugar, a little at a time. Then add in the vanilla and milk, to thin out the frosting.
Add in the neon purple food coloring. I did 2 drops of the Neon purple. Beat for 5 minutes until super silky.
Place the frosting in a piping bag, with a 1M or 2D piping tip.
How to Assemble Halloween Cupcakes
Step 5: Remove the cupcake from the liner, and slice in half.
Step 6: Place half the cupcake in a jar, upside down. Just keep it on the bottom of the jar.
Step 7: Add a layer of frosting. Make sure to apply even pressure the whole time as you create your circle.
Step 8: Top with the other half of the cupcake and repeat the frosting on top. Then add one more cupcake, and repeat frosting again.
Step 9: Place the Frankenstein on the center of the jar, for a Frankenstein cupcake in a jar treat.
Helpful tips for DIY Halloween cupcakes and Halloween cupcake decorations tricks.
- You want 3 layers of cupcakes in each jar, with a layer of frosting in between.
- Top your cupcakes with a store bought treat if you don’t want to make the Frankenstein.
- Use even pressure when you make the circle of frosting between the layers.
- Gently sit the cupcake on top of the frosting, try not to push down and smoosh the frosting.
- Add Halloween sprinkles in the layers of cake and frosting if you want added texture and color.
- Store these cupcakes in an airtight container until ready to serve, so you don’t dry out the cupcakes.
Variations To Recipe
- Use homemade cake batter instead of boxed cake if you want.
- Color the cake mix any color you want.
- Same for the frosting, choose any color of frosting. I find neon colors work the best in terms of food coloring.
- You do not have to top the cupcakes with the Frankenstein if you don’t want, I just love the way it looks.
- Add on fun Halloween candy to dress up and give as optional Halloween cupcake toppers.
- You can use chocolate cake instead of white cake if you want.
Here are a few helpful tips for these silly scary Halloween cupcakes! A simple frankenstein cupcake recipe.
I baked my cupcakes at 350 degrees for 15-18 minutes. You can stick a toothpick in the center of the cupcake to feel if they are baked. No wet batter will be on the toothpick when you pull it out.
Go right ahead and freeze the cupcakes if you want. You can freeze them before you slice and assemble them in a jar. Or after, just place lid on the jar and leave of the Rice Krispies treat, or place the whole treat in an airtight container.
Cupcakes will freeze 3-4 months. Thaw in the fridge in an airtight container in the fridge.
Buttercream frosting does need to be refrigerated, otherwise it will begin to break down.
