Bloody Broken Glass Cupcakes

Step 1
Preheat an oven to 350 degrees F (175 degrees C). Line 2, 12-cupcake tins with paper cupcake liners.

Step 2
Blend cake mix, 1 cup water, vegetable oil, and eggs in a large bowl. Beat with a mixer on low speed for 2 minutes. Divide cake batter between lined cupcake tins.

Step 3
Bake cupcakes in preheated oven until a toothpick inserted in the center comes out clean, 18 to 22 minutes. Cool completely. Frost cupcakes with white frosting.

Step 4
Make the sugar glass. Mix 2 cups water, 1 cup corn syrup, white sugar, and cream of tartar in a large saucepan; bring to a boil. Use a candy thermometer and boil sugar syrup until temperature reaches 300 degrees (hard ball), stirring constantly. The mixture will thicken as water evaporates. When sugar reaches 300 degrees, quickly pour onto a metal baking pan. Cool until completely hardened. Break into "shards" using a meat mallet.

Step 5
Make the edible blood. Mix together 1/2 cup corn syrup and cornstarch in a large bowl. Slowly stir in the 1/4 cup of water, adding more if necessary, until the corn syrup mixture has thickened to the consistency of blood. Stir in the red and blue food coloring.

Step 6
Stab each frosted cupcake with a few shards of broken sugar glass. Drizzle on drops of "blood" to complete the effect.
