Frankenstein Cupcakes in A Jar are a fun and easy Halloween cupcake recipe. Green cupcakes, purple buttercream, and a Frankenstein Rice Krispies Treat!
Preheat the oven to 350 degrees, and line you cupcake pan with liners. Mix up the cupcake batter. Cake mix, water, egg, and vanilla. Then color with food coloring.
Pour the batter 3/4 the way full, and then bake 15-18 minutes until they are fully cooked. Then allow to cool on cooling rack until fully cooled.
While cupcakes are cooling I made the Frankenstein Rice Krispies treats.
Then in a bowl you will work on your buttercream. Beat your butter on medium speed for a few minutes until fluffy. Then slowly mix in the powdered sugar.
Add in the vanilla and milk and beat till it is incorporated. It takes around 2 minutes.
Add in the food coloring, and create the desired color you want. Then beat for 5 minutes or until super silky.
Put the frosting in a piping bag and then use a 1M or 2D piping tip.
To assemble the cupcakes, slice cupcakes in half. Place one half of the cupcake in a jar.
Squeeze a circle of frosting on top, and then add another half of cupcake, more frosting, then cupcake, and then top with frosting.
Stick your Frankenstein Rice Krispies pop in, and add sprinkles if you want.
Serve up these Frankenstein cupcakes in a jar!
Notes
I recommend using a piping bag as it allows more control than a Ziploc bag.
Color the cake mix and the frosting to your desired color. I prefer neon food coloring for this recipe.
Sprinkles are optional.
You want 3 layers of cupcake and 3 layers of frosting in each jar.
You can use homemade cake batter instead of boxed if you want.
Store in an airtight container until ready to serve.
