Ingredients

16 Frankenstein Rice Krispies pops (tutorial here)
1 box white cake mix (15.25 oz)
3 eggs
1 cup water
1 teaspoon vanilla extract
2 drops neon green gel food coloring
2 cups softened butter
5 cups powdered sugar
2 teaspoons vanilla extract
1-2 drops neon purple gel food coloring

Instructions

Step 1: Preheat the oven to 350°F (175°C) and line your cupcake pan with liners. In a bowl, mix the cake mix, water, eggs, and 1 teaspoon vanilla until smooth. Add the neon green gel food coloring and stir until the color is even.
Step 2: Pour the batter into the cupcake liners, filling each about 3/4 full. Bake for 15-18 minutes or until a toothpick inserted in the center comes out clean. Remove from oven and let cool completely on a wire rack.
Step 3: While the cupcakes cool, prepare your Frankenstein Rice Krispies treats according to your tutorial or recipe.
Step 4: To make the buttercream frosting, beat the softened butter on medium speed until fluffy, about 2-3 minutes. Gradually add the powdered sugar and continue mixing until combined.
Step 5: Add 2 teaspoons vanilla and 1-2 drops neon purple gel food coloring. Beat the frosting for about 5 minutes until silky and smooth.
Step 6: Spoon the frosting into a piping bag fitted with a 1M or 2D piping tip for easy decorating.
Step 7: Slice each cooled cupcake in half horizontally. Place one half into a clean jar.
Step 8: Pipe a circle of frosting over the cupcake half, then add the next cupcake half on top. Repeat layering with frosting and cupcake until the jar is full, finishing with frosting on top.
Step 9: Insert a Frankenstein Rice Krispies pop into each jar and add sprinkles if desired for extra decoration.
Step 10: Serve your whimsical Frankenstein Cupcakes in a Jar and enjoy!

Tips & Variations

For a more vibrant green, add gel food coloring a drop at a time until you reach the desired shade.
Try using different colored sprinkles to match other Halloween themes or party colors.
If you prefer, substitute the neon purple frosting color with black or gray to keep the spooky vibe.
Use mini jars or clear cups for a nice presentation and portion control.

Storage

Store the cupcakes in jars with tight lids in the refrigerator for up to 3 days. Allow them to come to room temperature before serving for the best texture. Buttercream frosting can firm up when chilled but softens quickly at room temperature. For longer storage, freeze the jars without the Frankenstein pops for up to one month and thaw overnight in the fridge.

How to Serve

Three clear glass jars show layered desserts sitting on a white marbled surface with scattered colorful sprinkles. Each jar has three layers of light green cake alternating with thick swirls of bright pink frosting. On top of each jar stands a green rectangular cookie decorated with black icing to form a face with big white and black eyes and a wavy mouth, resembling a spooky character. The cookies have a textured surface and black icing as hair on top. Behind the jars, a small white pumpkin and a wooden spoon add to the scene. Photo taken with an iphone --ar 4:5 --v 7
