The faux-blood glaze can be made days in advance and warmed briefly for a fresh, sinister drip right before serving. Need a tweak? A gluten-free flour blend or plant-based cream cheese swaps in seamlessly without sacrificing flair.
All-purpose flour, 1 ¼ cups (160 g)
Preheat the oven to 350°F
For a richer “blood” effect, stir a teaspoon of raspberry preserves into the glaze and warm it just until pourable—too hot and it turns translucent. Let the frosted cupcakes chill 15 minutes, then spoon on the glaze; the cold surface firms the drips in place for clean, photo-worthy streaks.
