Step 1: Preparation and Oven Setup Preheat your oven to 350°F (175°C). Lightly grease two 6-cavity donut pans with non-stick cooking spray or a little bit of melted butter to ensure the donuts pop out easily after baking.
Step 2: Whisking Dry Ingredients In a large mixing bowl, sift together the all-purpose flour, cocoa powder, granulated sugar, baking powder, and salt. Sifting helps remove any lumps from the cocoa powder and ensures a light, airy donut texture.
Step 3: Combining Wet Ingredients In a separate medium bowl, whisk together the buttermilk, egg, melted butter, and vanilla extract. Stir in the red gel food coloring until the mixture is a bright, vibrant crimson.
Step 4: Mixing the Batter Gently pour the wet ingredients into the dry ingredients. Use a spatula to fold them together until just combined. Be careful not to overmix, as this can make the donuts tough and rubbery.
Step 5: Filling the Pans and Baking Transfer the batter into a piping bag or a large zip-top bag with the corner snipped off. Pipe the batter into the prepared donut cavities, filling them about 2/3 full. Bake for 10 to 12 minutes, or until a toothpick inserted into the thickest part comes out clean.
Step 6: Cooling and Glazing Let the donuts cool in the pan for 5 minutes before transferring them to a wire rack to cool completely. While they cool, whisk the softened cream cheese, powdered sugar, and milk together until smooth. Once cooled, dip the top of each donut into the cream cheese glaze.
Step 7: Adding the Vampire Bite While the glaze is still slightly tacky, place a pair of plastic vampire fangs into the center hole of each donut. In a small microwave-safe bowl, warm the jam for 10 seconds to thin it out. Use a toothpick or a small spoon to drip two “blood” spots near the fangs and let some jam run down the side of the donut.
