🧾 Main Ingredients Notes

• Cupcakes: Use your favorite recipe or purchase already prepared. I've included a simple chocolate cupcake recipe below.
• Vanilla Buttercream Frosting: You can make your own, or purchase premade frosting. It's simple to make your own vanilla buttercream, the recipe below. Another option is to use softened cream cheese frosting mixed with just a bit of powdered sugar and vanilla paste.
• Red Gel Color: For a clean line, use the red food coloring gel color right out of the tube. For something a little messier, mix the color with corn syrup. *If you don't want o use food coloring you can get a great effect using a raspberry jam, it won't have a clean line but will have a messier look!
• Creepy Crawly decorations optional

See the recipe card for ingredient quantities.

Vanilla Buttercream from Scratch

It's really easy and only takes a few minutes. You can also make the buttercream a couple of days before you decorate the cupcakes.

½ cup unsalted butter soft and at room temperature
1 ½ cups powdered sugar (confectioners sugar)
1 tablespoon + 2 teaspoons heavy cream
½ teaspoon vanilla extract
Pinch fine table salt (omit salt if using salted butter)

• Add the butter to a medium bowl and use a hand mixer on medium speed to beat the butter until smooth and creamy, This only takes a couple of minutes or less.
• Add in sugar, cream, vanilla, and salt and mix at low speed until the ingredients are mixed.
• Next, increase the speed to medium-high and beat until smooth and fluffy, this usually takes 2-3 minutes when making a small batch. If the buttercream is too thick, add a little more cream, if it’s too thin, add more powdered sugar.
• The buttercream is ready to use immediately. If making ahead of time, place the buttercream in a Ziploc bag and refrigerate for up to 1 week. When ready to use bring the frosting back to room temperature,

🧁Brain Cupcake Decorating Instructions

(Note: please see the recipe card at the bottom of the post for the complete written instructions.)

Start with 6 prebaked chocolate cupcakes. Assemble the piping bag, and attach the coupler and tip. No piping bag? You can also use a Ziploc bag fitted with a coupler and round tip.

Add the vanilla buttercream into the piping bag and press out two lines of icing across the middle of the cupcake. Make sure you lift the piping bag over the cupcakes and allow the icing to fall (this helps keep the shape)

Next, make a tight zigzag line on both sides of the two straight lines.

Make another zigzag line on the edges.

For a cleaner final presentation use a bottle of red gel sparkle food coloring

Pipe the red along the ridges of the buttercream.

For the more gruesome appearance mix 1 tablespoon corn syrup with 1-2 drops of the red gel food coloring.
