Bloody Syringe Cupcakes with Red Gel Filling

Introduction

Few Halloween treats are as chillingly fun and crowd-pleasing as Bloody Syringe Cupcakes. These rich chocolate cupcakes are filled with a sweet red gel that oozes out when bitten into, mimicking “blood.” To complete the creepy effect, each cupcake is topped with a frosting swirl and finished with a mini plastic syringe filled with the same red gel—making them interactive, festive, and downright spooky.

This recipe is a fantastic way to combine delicious flavor with playful Halloween theatrics. Imagine guests squeezing the syringes into their cupcakes for that dramatic, gory effect—it’s equal parts gross and delightful!

Plus, it’s versatile—you can play with flavors (red velvet, vanilla, or even pumpkin spice) and fillings (raspberry jam, strawberry sauce, or cherry pie filling). Every time I make these cupcakes, they instantly steal the spotlight on the dessert table.

For Decoration

• 12 small plastic syringes (food-safe, 5–10 ml size)

Cooking Directions

1. Bake the Cupcakes
   • Preheat oven to 350°F (175°C). Line a 12-cup muffin tin with cupcake liners.
   • In a large bowl, whisk flour, sugar, cocoa, baking powder, baking soda, and salt.

   • Stir in hot water/coffee until batter is thin.
   • Fill liners ⅔ full and bake for 18–20 minutes. Cool completely.
2. Prepare the Red Gel Filling
   • Warm jam slightly, then stir in red food coloring until it resembles “blood.”
   • Transfer some into syringes, and reserve the rest for filling cupcakes.
3. Make the Frosting
   • Beat butter until fluffy.
   • Gradually add powdered sugar, cream, vanilla, and salt. Beat until smooth and pipeable.
4. Assemble the Cupcakes
   • Use a cupcake corer or small knife to cut a hole in the center of each cupcake.
   • Fill holes with red gel filling.
   • Pipe frosting over the top to cover the filled centers.
5. Decorate
   • Insert a syringe filled with red gel into each cupcake.
   • Optionally, drizzle a little gel over frosting for a dramatic “blood splatter” look.

Step-by-Step Preparation Method

3. Whip buttercream → smooth + fluffy.
4. Core cupcakes → fill with red gel.
5. Frost cupcakes → swirl with piping bag.
6. Insert syringe + drizzle with “blood.”

How to Serve

Serve cupcakes on a dark platter with fake cobwebs or scattered candy eyeballs for effect. Guests can squeeze the syringe before biting for maximum spooky drama! Perfect as a centerpiece for your Halloween dessert table.

Recipe Tips

• Use gel food coloring for the deepest red.
• Chill filled cupcakes before frosting to prevent gel from seeping out.
• For a more realistic effect, splatter red gel across cupcakes using a clean brush or spoon.
• Test syringes beforehand to ensure they work smoothly.

Variations

• Red Velvet Cupcakes: Perfectly spooky red interior.
• Pumpkin Spice Version: Swap cocoa powder for pumpkin pie spice + pumpkin puree.
• Black Frosting: Tint frosting black for extra gothic appeal.
