Ingredients
Below are the main ingredient groups for these cupcakes. Scroll to the recipe card for exact amounts and the full instructions.
For the cupcakes and Glass Candy
- 24 baked and cooled cupcakes: Use store-bought mix or homemade red velvet cupcakes. Any cupcake flavor will work.
- Water
- Light corn syrup: Helps prevent crystallization in the sugar glass. Golden or glucose syrup can be substituted.
- Granulated sugar: A good-quality cane sugar yields consistent results.
- Clear vanilla extract: Optional flavoring for the sugar glass; use clear extract to avoid coloring the shards.
For the Frosting
- Unsalted butter and salt: Use cool room-temperature butter for a smooth buttercream. Omit extra salt if using salted butter.
- Milk: Any milk works; use to adjust frosting consistency.
- Vanilla extract: Use your preferred vanilla for flavor.
- Powdered sugar: This is an American buttercream, so powdered sugar is the main sweetener; sift after measuring.
For the Blood Topping
- Sweetened condensed milk: Thick and slightly off-white, it gives realistic texture and color. Corn syrup or strawberry syrup can be used instead.
- Red gel food coloring: Use gel color for a vibrant blood-red shade.
Equipment
These tools will help you make sugar glass safely and decorate the cupcakes neatly.
- Baking sheet: A flat sheet to pour and set the sugar glass.
- Non-stick foil or spray: Line the sheet so the candy releases easily.
- Medium saucepan: Use a 3–4 quart pan to avoid boil-over while cooking the syrup.
- Pastry brush: For wiping sugar crystals from the pan walls.
- Candy thermometer: Essential—small temperature differences change the candy’s texture.
- Kitchen mallet: To break set sugar glass into jagged shards; a rolling pin or heavy spoon can substitute.
- Mixer: Stand or hand mixer for whipping buttercream.
- Piping bags and tips: For piping swirls and the blood drizzle; a disposable bag or zip-top bag works as a simple hack.
- Piping tip: A large closed star tip works well for swirls.
- Cupcake liners: Optional festive liners add Halloween flair.

Bloody Glass Cupcakes
Ingredients
- 24 baked and cooled cupcakes (from scratch or your favorite mix)
For the Edible Sugar Glass Shards
- 4 fl oz (1/2 cup) water
- 8.25 oz (3/4 cup) light corn syrup (or glucose/golden syrup)
- 14 oz (2 cups) granulated sugar
- 2 tsp clear vanilla extract (optional)
For the Frosting
- 1 lb (2 cups) unsalted butter, cool room temperature
- 2 TBSP milk (or water), plus more to adjust
- 1/2 tsp salt
- 1 TBSP vanilla extract
- 28 oz (7 cups) powdered sugar, sifted after measuring
For the Blood Topping
- 1/2 cup sweetened condensed milk (or corn syrup or strawberry syrup)
- Red gel food coloring
Instructions
Make Glass Candy Shards
- Prepare baking sheet: Line a baking sheet with non-stick foil or spray it with non-stick cooking spray.
- Heat water, corn syrup, and sugar: In a medium saucepan combine water, corn syrup, and granulated sugar. Heat over medium-high and stir until the sugar dissolves.
- Wipe pan with pastry brush: When the mixture simmers, brush the pan walls with a wet pastry brush to prevent crystallization. Insert a candy thermometer.
- Cook without stirring: Continue to cook without stirring until the syrup reaches 290°F (143°C). Watch carefully—temperature matters.
- Remove from heat and add flavoring: Take the pan off the heat, wait until rapid bubbles subside, then stir in clear vanilla if using.
- Pour candy to set: Pour the syrup onto the prepared sheet and spread into a thin layer. Let cool completely at room temperature.
- Break: Once set, break the sugar sheet into jagged shards with a mallet or heavy tool. Store in an airtight container in a dry place up to a week (see notes).
Make the Frosting
- Beat the butter: In a large bowl, beat butter on medium speed until very pale, 3–4 minutes.
- Add milk, salt, and vanilla: Add 1 TBSP milk, salt, and vanilla; mix to combine.
- Slowly add powdered sugar: With mixer on low, add powdered sugar gradually. Scrape bowl and beat on medium for 30 seconds.
- Adjust consistency: If too stiff, add milk a teaspoon at a time. Adjust with more powdered sugar or milk to reach desired texture.
- Use or store: Use immediately or store in an airtight container for up to a week. Re-whip if needed after chilling.
Make the Blood Topping
- Mix milk and food coloring: Combine sweetened condensed milk with red gel food coloring until a blood-red color is achieved.
Frost and Decorate the Cupcakes
- Prep piping bags: Fit a piping bag with a large closed star tip for the buttercream and a small round tip for the blood topping. A zip-top bag with a snipped corner also works.
- Frost and top with shards: Pipe a white buttercream swirl on each cupcake and insert a few sugar glass shards at varying angles.
- Drizzle topping: Drizzle the red topping over the shards so it drips down the frosting. Serve immediately.
- Store: Store extras in an airtight container at room temperature for 2–3 days; sugar glass can become sticky over time when in contact with frosting.
- Make-ahead: Cupcakes can be frosted in advance and refrigerated up to a week. Add shards and blood topping just before serving; bring to room temperature for best flavor.
Recipe Notes
Make the glass candy in advance: Sugar shards can be made up to 7 days ahead and stored in an airtight container in a dry place. In humid climates they may become sticky after 2–3 days; consider using desiccant packs if storing longer.
Make the frosting in advance: Buttercream keeps for several days refrigerated in an airtight container. Press plastic wrap onto the surface, then bring to room temperature and re-whip before using.
Adjust frosting consistency: Temperature, butter brand, and kitchen conditions affect texture. Tweak with milk or powdered sugar as needed.
Measuring Tips
Recipes are developed using weight measurements; a kitchen scale is recommended for accuracy. Volume equivalents are provided, but weights yield the most consistent baking results.

🍬 Candy Making Tips
Candy making combines science and technique. Key tips: use a reliable candy thermometer, prevent crystallization by brushing down pan walls, and be mindful of humidity when storing sugar glass. If you’re new to candy making, practice with small batches and read up on thermometer use and temperature adjustments for altitude.
💡 FAQs
Use a zip-top plastic bag filled with frosting and snip one corner to pipe. The size of the cut controls the flow; you won’t get the same ridged effect as a star tip, but you can still create attractive swirls.
Make the cupcakes and frosting in advance: Cupcakes can be frosted and stored refrigerated in an airtight container for up to a week. Add glass shards and the blood topping just before serving and bring chilled cupcakes to room temperature for best flavor.
Make the glass candy ahead: Sugar shards can be made up to 7 days ahead in a dry location; humid climates shorten shelf life to 2–3 days.
Store extras in an airtight container at room temperature for 2–3 days. The sugar glass will become sticky the longer it contacts the frosting.
